Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

1.0 IntroductionThis Project Application and Environmental Assessment Report (EAR) is submitted to the Minister for Planning pursuant to Part 3A of the Environmental Planning and Assessment Act 1979 (EP&A Act). The Project Application seeks approval for bulk excavation, remediation, and basement car parking at Barangaroo as described in Section 4.0 of this EAR.

The EAR has been prepared by JBA Urban Planning Consultants Pty Ltd, for the proponent, Lend Lease (Millers Point) Pty Limited (LL), and is based on plans and drawings provided by Lend Lease Design and Aspect/Oculus (Appendix A) and the supporting technical documents provided by the expert consultant team (see Table of Contents).

The EAR describes the site, its environs and the proposed development, and includes an assessment of the proposal in accordance with the Director-General’s Environmental Assessment Requirements (DGRs) under Part 3A of the EP&A Act (Appendix B). It should be read in conjunction with the studies and other information appended to this report which address the DGRs for the environmental assessment. The studies provide a technical assessment of the environmental impact of the proposed development, and recommend proposed mitigation measures to manage potential environmental impacts associated with the proposal.

1.1 Background

1.1.1 Approved Concept Plan An international urban design competition for the East Darling Harbour site (now known as Barangaroo) was held in 2005, attracting 139 entries from around the world. The winning design by Hill Thalis Architecture + Urban Projects, Paul Berkemeier Architects and Jane Irwin Landscape Architecture was announced in March 2006.

The Barangaroo Concept Plan (based on the winning Hill Thalis scheme) was approved in February 2007. The Concept Plan covers urban design and policy initiatives and is the statutory planning approval to guide the urban renewal of Barangaroo.

The Concept Plan approval (as modified) provides for:

A mixed use development involving a maximum of 489,500m� 2 gross floor area (GFA), comprising of:

Approximately 11 hectares of new public open space / public domain, with �a range of formal and informal open spaces serving separate recreational functions and including a 1.4km public foreshore promenade.

A maximum of 8,500m� 2 GFA for a passenger terminal and a maximum of 3,000m2 GFA for active uses that support the public domain within the public recreation zone.

Built form design principles, maximum building heights and GFA for each �development block within the mixed use zone.

Public domain landscape concept, including parks, streets and �pedestrian connections.

Alteration of the existing seawalls and creation of two enlarged coves and a �natural headland.

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The Statements of Commitment approved under the existing Concept Plan (as modified) require a series of Implementation Plans and Strategies to be prepared prior to the lodgement of future project applications to address:

Design Excellence; �

Public Domain; �

Transport Management and Access; �

Community and Social Impacts; �

Utility Services and Infrastructure; �

Housing; �

Marketing and Promotion; �

Retail Management; and �

Geotechnical and Environmental Site Remediation. �

The Statements of Commitment require the establishment of Technical Working Groups to prepare each Implementation Plan and Strategy. The Technical Working Groups have been convened and meet regularly (refer to Section 3 for further details).

1.1.2 Concept Plan ModificationsThe approved Concept Plan has been modified three times since originally being approved. MP 06-0162 MOD 3 was most recently approved in November 2009. As described above, the approved Concept Plan provides for a mixed use development with a maximum of 489,500m2 GFA contained within 8 blocks on a total site area of 22 hectares, comprised of:

a maximum of 97,075m� 2 and a minimum of 58,245m2 residential GFA;

a maximum of 50,000m� 2 GFA for tourist uses;

a maximum of 39,000m� 2 GFA for retail uses; and

a minimum of 2,000m� 2 GFA for community uses.

1.1.3 Demolition Project Application On 15 November 2007, the Minister for Planning granted project approval for demolition and preliminary site establishment works to prepare the site for future development, in accordance with the Barangaroo Concept Plan (MP 07_0077).

Prepared on behalf of the Sydney Harbour Foreshore Authority, the approved works included:

Demolition of structures including Transit sheds 3, 4, 5 and 6 and �associated structures;

Demolition of transit shed 8, entry gatehouse, 13 light towers;�

Demolition of the Sydney Ports Amenities building, Sydney Ports Office �building, and Wharf 8 Passenger Terminal;

Removal of the vehicle wash down bay and diesel tanks and storage shed; and�

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

1.1.4 Headland Park An early works Project Application is currently being prepared by the Barangaroo Delivery Authority to prepare the northern extremities of the Barangaroo site for the construction of the Headland Park. The Project Application is expected to be lodged in June 2010 and will seek approval for:

Demolition of above ground structures and establishment of a construction �compound including sheds and site hoardings;

Bulk earthworks, including placement of fill as part of the formation of the �final landform;

Extraction of rough sawn sandstone blocks for reuse within the Barangaroo �site from beneath the existing concrete apron; and

Retention or relocation (yet to be determined) of the existing Sewage Pumping �Station and Network.

1.1.5 Stage 1 Tender and Bid ProcessThe 22 hectare Barangaroo site has been divided into three distinct redevelopment areas (from north to south) – the Headland Park, Barangaroo Stage 2 and Barangaroo Stage 1.

LL was successfully appointed as the preferred proponent to develop Barangaroo Stage 1 (otherwise known as Barangaroo South) on 20 December 2009.

LL’s appointment follows approximately 18 months of open and subsequently selective tendering by multiple consortia. At each stage of the process, the consortia were required to develop and submit increasingly detailed designs for Stage 1 of the Barangaroo site, which were evaluated by the Barangaroo Delivery Authority and its evaluation panel.

The Stage 1 bid chronology can be broadly summarised as follows:

April 2008 – Stage 1 Expression of Interest released;�

June 2008 – Stage 1 Expression of Interest closes;�

September 2008 – Shortlist of 3 proponents (including LL) announced and �invited to participate in the Stage 1 Request for Detailed Proposals (RFDP);

August 2009 – LL and Brookfield Multiplex chosen as final 2 proponents to �particpate in the Final Phase RFDP process;

November 2009 – Final Phase bids close; and�

December 2009 – LL announced as winning preferred proponent.�

The scheme submitted by LL and selected by the State Government was chosen as the winning bid on the basis that it exhibits the urban structure, place making, sustainability, and financial drivers required to ensure the viability of Barangaroo’s Southern Precinct.

This Project Application forms the first of a series of individual Project Applications that LL will be submitting to deliver Stage 1 of the Barangaroo development. This Project Application is consistent with the established planning framework for the site, including the approved Concept Plan, and can therefore be lodged under the approved Concept Plan.

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

1.1.6 Barangaroo Delivery Authority The Barangaroo Delivery Authority was established under the Barangaroo Delivery Authority Act 2009 to manage the redevelopment of Barangaroo and to deliver world class benchmarks in urban design, public domain and sustainability.

The creation of the Authority reinforces the NSW Government’s commitment to the delivery of Barangaroo in a coordinated and financially responsible manner.

The Barangaroo Delivery Authority is the majority landowner of the site.

1.2 Summary of Approval SoughtClause 5(1) of Part 12 of Schedule 3 of the Major Development SEPP states that Part 3A of the EP&A Act applies to development within the Barangaroo site that has a capital investment value of more than $5 million. The proposal has a capital investment value of over$190 million, and Part 3A of the EP&A Act therefore applies.

The Project Application seeks approval for the bulk excavation and construction of a basement car park to accommodate up to 880 car parking spaces and associated services and infrastructure to support the initial phases of the future development of Barangaroo Stage 1.

Approval is not sought for the detailed final internal layout, allocation of parking spaces to future land uses/specific buildings, or for operation of the basement car park at this stage.

The proposed basement car park is located predominantly within Blocks 2 and 3 of the Barangaroo site as identified under the approved Concept Plan and has been designed in accordance with the approved Concept Plan.

The basement car park has been designed to maintain maximum flexibility with respect to the potential options for the detailed design and distribution of above ground floor space (commercial, residential, community and retail floor space).

Particularly, the proposed basement car park has been designed such that the building core locations, final car parking provision and layout, and pedestrian and vehicular access arrangements (including lifts and fire stairs) are can continue to be concurrently designed whilst having regard to the future built form above the basement car park, which is to be the subject of separate detailed Project Application(s) in the future.

The proposed basement car park has also been designed such that it is capable of expansion / connection to additional basement areas at subsequent stages of the development to accommodate additional parking as required to support the proposed gross floor area and land use mix as the overall Barangaroo Stage 1 development proceeds.

In summary, this Project Application seeks approval for:

demolition of any existing structures and footings, part of an underground �cassion wall, hardstand areas, removal of piles, and removal of existing vegetation within Blocks 1, 2 and 3 and within the adjacent public domain area, which have not been previously approved to be demolished or removed under MP 07-0077 Demolition Works;

site establishment, including provision of concrete crushing infrastructure, �environmental protection structures, de-watering infrastructure, and groundwater treatment;

bulk earthworks for the purposes of excavating for the basement within �Blocks 1,2 and 3 and the adjacent public domain area;

on-site treatment and remediation of contaminated soils;�

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

transportation of excavated material to temporary locations to the site of �the Headland Park for future placement and land forming by the Barangaroo Delivery Authority under its Headland Park Early Works Project Application;

temporary stockpiling of excavated material across the Barangaroo site �as required;

transportation and disposal of material off site, where required; �

structural works, comprising the construction of:�

foundations (piling, caps and footings);-

basement levels; -

perimeter retention system to basement walls; and-

all associated elements and structures; -

up to 880 car parking spaces which equates to the car parking required to �support GFA as envisaged by the approved Concept Plan for Blocks 2 and 3, and part of Block 4 (noting that it has been displaced by the enlarged Southern Cove) in accordance with the car parking rates approved under the Concept Plan;

indicative parking layout, loading, plant location, bicycle parking and �associated amenities;

road works, including the extension of Margaret Street (known as Margaret �Street West in the approved Concept Plan) and Lime Street;

construction of temporary vehicular access from Hickson Road and �permanent vehicular access from Margaret Street West;

associated utilities and infrastructure works including decommissioning and/�or relocation of services as outlined in the Infrastructure Concept Plan at Appendix S; and

temporary use of the basement for construction related storage and activity.�

This Project Application does not seek consent for the following development, which will be the subject of separate future Project Applications as relevant:

building works, including the core/foundations for future commercial and �residential buildings and the public domain above the basement level;

the final total number and allocation of car parking spaces relevant to the �amount and land use mix of GFA ultimately approved within the overall Stage 1 development;

detailed layout and operation of the car parking associated with each building;�

any retail uses in the basement; �

any precinct infrastructure services other than those identified in this �Project Application;

permanent access to the basement from Hickson Road, which is proposed to �be provided once remediation of the DECCW Declaration Area has occurred;

construction of any future basement areas outside the Project Application �Site; and

detailed landscaping and public domain works which will be the subject �of future Project Applications for Blocks 1-4 and the public domain/ foreshore precinct.

1.2.1 Future Concept Plan Modification Implementation of LL’s Stage 1 winning scheme will ultimately necessitate a Concept Plan Modification to address LL’s proposed height and gross floor area increases, and the establishment of a new pier and landmark building extending into the Harbour.

Director General’s environmental assessment requirements have been issued for the Concept Plan Modification. The proposed Concept Plan Modification will be submitted to the Department of Planning shortly.

This Project Application does not rely on the proposed Concept Plan Modification. Approval is being sought for the carrying out of excavation, construction of the basement levels, and associated servicing and infrastructure works, none of which impact upon or are impacted by the scope of the proposed Concept Plan Modifications.

2.4 Existing Development and Structures

2.4.1 Built FormThe Project Application Site is predominantly covered by hardstand areas including concrete and bitumen. A number of structures currently occupy the site, including:

the � Wharf 8 Passenger Terminal, car parking and landscaped areas;

a disused brick office building, security gate house and electrical substation �located in the southeast;

Sydney Ports Authority workshop building in the northeast; and�

a nu� mber of light poles spaced across the entire area.

The Passenger Terminal consists of a main building in the central portion of the site (containing a warehouse, offices and main passenger terminal area) and a cruise ship loading dock on Darling Harbour. The Passenger Terminal is proposed to be demolished in July 2010 (under MP 07_0077) and replaced with a temporary cruise terminal, which was erected to the north of Block 5 and is complete and operational.

The Sydney Ports Authority workshop building is currently being used by the Barangaroo Delivery Authority as a public display for the proposed Barangaroo development.

2.4.2 Infrastructure and Services

Stormwater

The existing stormwater network is characterised by a series of transverse piped stormwater systems (typically between 450mm to 600mm in diameter) draining Hickson Road and other external catchments through the Barangaroo site directly to the Harbour.

Water

The existing water supplies to the Barangaroo site are supplied from a 300mm diameter Sydney Water main in Hickson Road.

Sewer

There is an existing sewer network traversing the basement footprint which drains to an existing Sydney Water sewage pumping station SP1129. This pumping station is located outside the basement footprint. There is no other existing sewer network passing through the basement footprint.

Electricity

There are a number of existing 5kV HV Energy Australia (EA) supplies to the Barangaroo site. There is an existing substation (DH No.7) currently within the Project Application Site that serves the Passenger Terminal and other existing buildings on site.

Telecommunications

A telephone exchange is located in Kent Street, and existing Telstra copper lines feed into the site at various locations along Hickson Road and Dalgety Road. There are mobile phone equipment shelters located near Hickson Road.

Natural GasThere is an existing 110mmm low pressure (7kPa) nylon gas main along Hickson Road and a high pressure gas main located at the corner of Sussex and Napoleon Streets. There is no existing high pressure main connection serving the Barangaroo site, however, there are small low pressure connections.

2.5 Traffic and Transport

2.5.1 Vehicular and Pedestrian Access Hickson Road connects into Sussex Street south of Napolean Street and is the predominant north-south access road for Stage 1 and consequently the Project Application Site.

Local road access to the Barangaroo site area is provided as follows:

From the CBD via Napoleon Street;�

From Millers Point via Dalgety Road;�

Via George Street from the north east;�

Via Sussex Street/Kent Street/Napoleon Street from the southern CBD;�

Via Harbour Street, Wheat Road (through King Street Wharf) to Shelley �Street from the south; and

Via the east-west alignment of Napoleon Street and Margaret Street.�

Over 1,500 vehicles pass through the intersection of Hickson Road, Napolean Street and Sussex Street (refer to ARUP Traffic and Parking Report at Appendix D). Key local intersections surrounding the site have been modelled as a component of previous studies, and were found as having existing reasonable levels of operation.

2.5.2 Public TransportThe site is served by the following public transport modes:

Rail:� Wynyard, Martin Place, Town Hall and Circular Quay railway stations are within viable walking distance of the Barangaroo site and provide frequent services throughout the day.

Bus:� There is a major bus interchange located at Wynyard Station for buses servicing the Hills District, Northern Beaches and the North Shore areas. These services all utilise the bus lane on the Harbour Bridge to access Wynyard.

� A number of bus routes also terminate in the vicinity of the Barangaroo site, King Street Wharf and Circular Quay.

Ferry:� Commuter ferry services arrive and depart from both King Street Wharf and Circular Quay.

Refer to Transport Management and Access Plan (Supplementary) prepared by ARUP at Appendix E.

2.5.3 Pedestrians and Cyclists

Pedestrian Access

Pedestrian access is available along all local roads, which are footpath lined. Pedestrian access is also available across the Barangaroo site and along the waterfront via fenced routes. Notwithstanding the high degree of pedestrian footpaths and thoroughfares, there are generally low levels of pedestrian activity adjacent to the site.

On days when the Passenger Terminal is operational, passengers arriving and departing the site use the Sussex Street / Shelley Street intersection to access Wynyard Station. This intersection is controlled by traffic signals and has pedestrian crossing facilities on all three approaches.

12 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

Pedestrian traffic movements to and from the Passenger Terminal are in the order of 1,700 pedestrian movements in total for each cruise ship visit, with the majority typically occurring between the hours of 11am and 2pm.

Bicycles

A bicycle lane exists along Hickson Road between Circular Quay and Napolean Street which is utilised by both commuter and recreational cyclists. Cycling connections to the site are being improved through the construction of separated cycleways along King Street (completed May 2009) and Kent Street (scheduled for completion early 2011).

Internally, the site is relatively flat which will encourage pedestrian and cycle movement.

The site is constrained however in that there is a considerable grade differential to other parts of the CBD and to Wynyard.

2.6 Physical Characteristics

2.6.1 TopographyThe ground surface of the entire Project Application Site is at an elevation of approximately 2m (AHD).

The surrounding landform (outside the bounds of the Site) rises rapidly to the east. A 10m high sandstone cliff is situated east of Hickson Road and Sussex Street and is likely to continue beneath the fill and alluvial materials present on the site (see Section 2.6.2 below).

2.6.2 Geology and GeomorphologyThe Geotechnical Report prepared by ARUP at Appendix F provides a detailed analysis of the geological and geomorphological characteristics of the Project Application Site.

The Sydney Geological Map Scale 1:100,000 and the Sydney Geological Map Scale 1:250,000 indicate the Barangaroo site is underlain by Hawkesbury Sandstone. Quaternary sediments and man-made fill overlay the Hawkesbury Sandstone. The majority of the Project Application Site is underlain by man-made fill, consistent with the knowledge that the Barangaroo site has been successively reclaimed since the 1800’s.

Structural lineaments and dykes of note are identified in Figure 1 of ARUP’s Geotechnical Report, and include:

The Luna Park Fault Zone located near the northern extent of the Barangaroo �Stage 1 area and which is associated with significant reductions in rock strength; and

The Pittman LIV Dyke which is inferred to traverse the northern extent of �the Barnagaroo Stage 1 area, approximately 300m north of the existing Passenger Terminal.

2.6.3 Groundwater and HydrogeologyThe groundwater profile beneath the Project Application Site is likely to be influenced by the groundwater flow from the east beneath the CBD and tidal fluctuations associated with Sydney Harbour.

Data collected in July 2006 indicates that the depth of groundwater ranged between 1.7m and 2.5m below ground level. Short term variations in groundwater levels were reported particularly close to the sea wall.

Page 21: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

13JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

A detailed chemical composition of the groundwater is provided in Section 4.5 of AECOM’s Remedial Action Plan (Appendix G). In summary, groundwater analysis indicates varying concentrations of contaminates. Detectable concentrations of TPH, PAHs and BTEX are limited to the north eastern area of the site and associated with the former gasworks. Heavy metal concentrations likely to be related to fill materials are present in groundwater across the site.

2.6.4 Soil LandscapesThe 1:100,000 Sydney Soil Landscape Map indicate the Project Application Site is underlain by disturbed soils.

A high probability of acid sulphate soil is associated with the estuarine sediments in Sydney Harbour. Accordingly, acid sulphate soil is likely to underlie the man-made fill materials that occupy the overall Stage 1 area. Refer to Acid Sulphate Soils Report prepared by AECOM at Appendix I.

2.6.5 Site ContaminationA number of site history studies and environmental site investigations have been undertaken to assess the extent and nature of contaminants within the Barangaroo site as a whole, as well as within the Stage 1 area and the Project Application Site specifically.

Investigations have revealed that both the soil and groundwater is contaminated, and that the extent of the contaminated materials varies across the site.

Concentrations of lead, total petroleum hydrocarbons (TBHs), benzene, xylenes and polycyclic aromatic hydrocarbons (PAHs) in the soil variably exceed criteria levels. The contamination is largely associated with the operation of the former gasworks, which were located immediately north of the Project Application Site; and from the importation of materials historically used to fill the site.

In May 2009, the Department of Environment, Climate Change and Water (DECCW) declared part of the Barangaroo site (Blocks 4 and 5) and immediately adjacent land within the Hickson Road reservation to be a remediation site under the Contaminated Land Management Act, 1997 (Declaration No. 21122) (known as the DECCW Declaration Area). No part of the Project Application Site forms part of the Declaration Area as demonstrated by Figure 4.

Remediation of that part of the Barangaroo site comprising Blocks 4 and 5 and the Southern Cove, and the adjacent area of Hickson Road, will the subject of a separate future Remediation Action Plan and Project Application(s).

ERM has prepared an Overarching Remedial Action Plan (RAP) for the Barangaroo site for the Barangaroo Delivery Authority (Appendix J). The Overarching RAP presents a summary of the contamination issues identified on the Barangaroo site and outlines an approach to the remediation of the site as a whole. A Site Auditor’s Statement has been received in relation to the Overarching RAP (Appendix K). The Overarching RAP requires that site specific RAPs be developed for the DECCW Declared Area and for the other development sites. Site specific Remedial Works Plan are also required, which are to detail remedial measures.

The Overarching RAP envisages that excavated material will be remediated (where required) and re-used within the Barangaroo site, including re-use for the construction of the proposed northern Headland Park (subject to a separate approval).

With respect to the Project Application Site, the Overarching RAP considers on-site treatment of contaminated material to be the most practical methodology. The Overarching RAP notes that on-site treatment of groundwater from dewatering excavations will also be required, however ongoing treatment of groundwater is not likely to be required following removal of contaminated material.

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

Figure 4 – DECCW Declared Area Source: DECCW Declaration

In accordance with the requirements of the Overarching RAP, a site specific RAP for Blocks 1, 2 and 3 and the public domain area within the Project Application Site has been prepared by AECOM and is included at Appendix G. As detailed at Appendix G the extent of contamination within the Project Application Site can be summarised as

Block 1� : contains no contaminated material and excavated material is accordingly expected to be suitable for re-use. No significant groundwater contamination has been identified in Block 1.

Block 2� : eight hotspots have been identified at various depths. The hotspots in Block 2 are attributed to the presence of localised contaminated material and are generally considered to present a minimal unacceptable risk to human health or the environment. Accordingly, the hotspots are not expected to require remediation, however further assessment is proposed to be undertaken (refer to Section 6.5). Groundwater beneath Block 2 exhibits traces of benzene, TPH and PAH, however concentrations are generally below acceptable limits of reporting.

Block 3� : potentially contaminated material is present in the north-eastern and north-western portions of Block 3 and is attributed to the former gasworks and filling activities undertaken in the past. Remediation of Block 3 will be undertaken in conformance with the Overarching RAP and site specific RAP. Detailed remediation requirements for contaminated material will be provided in the Human Health and Ecological Risk Assessment (HHERA) – refer to Section 6.5; and

Public Recreation Area� : three hotspots have been identified at various depths. The hotspots are located away from the former gasworks and are thought to be associated with the presence of contaminated fill materials. The hotspots in the Public Recreation Area are considered to present a minimal unacceptable risk to human health or the environment as their exceedances are marginal. Further, the hotspots are located below groundwater and will not be removed as part of the proposed works. Notwithstanding this, further assessment is proposed to be undertaken (refer to Section 6.5).

Full details of the soil and groundwater contamination and exceedence levels within the Project Application Site are documented in the AECOM report included at Appendix G.

2.6.6 Vegetation The Project Application Site is largely devoid of existing vegetation with the exception of landscaped areas comprising predominantly native species surrounding the existing Passenger Terminal and Sydney Ports Authority workshop building. The interface of the Project Application Site with Hickson Road is also characterised by mature Fig trees. Dominant species include Melalueca quinquenervia, Ficus micocarpa, Platanus x hybrida, Ficus benjamina, and Cupaniopsis anarcardioides.

The Tree Health and Assessment Report prepared by Jacksons Nature Works (Appendix L) provides a detailed species list of existing vegetation within the Project Application Site.

2.6.7 Heritage and Archaeology

Non Indigenous Heritage

Neither the Project Application Site nor any building/structure/element within it, is listed as a local or State heritage item.

The approved Concept Plan and subsequent Demolition Project Application comprehensively addressed the heritage significance of the Barangaroo site. The Heritage Impact Statement prepared for the site by City Plan Heritage in 2007 (refer to Demolition Project Application) also confirms the Project Application Site is not of heritage significance and does not exhibit heritage values (including existing buildings and structures).

Non-Indigenous Archaeology

A Non-Indigenous Archaeological Assessment undertaken by Casey and Lowe for the Barangaroo Stage 1 area and for land within the vicinity of the broader Barangaroo site indicates Local and State significant archaeological remains associated with former maritime infrastructure, ship building, and industrial activities, both on and adjacent to the Site, are likely to be present (Appendix M).

These may include:

Late 19� th and 20th Century wharfage timber piles;

19� th Century wharfage, yards and stores;

Gasworks remains and associated infrastructure;�

Early remains associated with maritime infrastructure, and examples of �maritime construction and foreshore remodelling; and

Henry Bass’ shipyard.�

Further investigations are required and are detailed in Sections 6.12.1 and 6.12.2.

Indigenous Heritage and Archaeology

A search of the Department of Environment, Climate Change and Water’s (DECCW’s) Aboriginal Heritage Information Management System (AHIMS) indicates that no known Aboriginal sites have been previously recorded within or in the vicinity of the Project Application Site or the broader Barangaroo site.

Comber Consultants have nonetheless undertaken an Aboriginal Archaeological and Cultural Heritage Assessment (Appendix N) which suggests that subsurface archaeological deposits containing artefact scatters and/or middens may be located within the eastern portion of the Barangaroo Stage1 area, including land within the Project Application Site and particularly near the original shoreline.

2.7 Surrounding DevelopmentThe proposed basement car park structure sits predominantly beneath the redevelopment sites of Blocks 2 and 3 and extends partially beneath the public domain foreshore area of the approved Concept Plan. The redevelopment of the land above the basement car park will be subject to future Project Applications. A description of the existing development and future proposed development envisaged under the approved Concept Plan (as modified) is outlined below.

2.7.1 Existing Development

To the North

Immediately north of the Project Application Site is the DECCW Declared Area which will be the subject of a future Project Application. Barangaroo Stage 2 and the site of the new Headland Park are further beyond.

To the East

To the immediate east of the site is Hickson Road and existing CBD development comprising Lend Lease’s headquarters – The Bond, Grafton Bond and The Sussex. Residential development is located east of these buildings, elevated above the site.

To the South

South of the site is the remainder of the Barangaroo site, being Block 1 which is proposed for commercial development. Beyond Block 1 lies the KPMG, Macquarie Bank and Amex buildings and the King Street Wharf precinct.

To the West

To the west of the site is Sydney Harbour and the waters of Darling Harbour. Further west is Darling Island.

2.7.2 Future Proposed Development

Block 2

Block 2 will accommodate new commercial buildings with ancillary retail uses, comprising approximately 211,907m2 of floor space. The development will also include public domain improvements around the new buildings on Block 2.

Block 3

Block 3 will accommodate new commercial buildings with ancillary retail uses. The buildings will comprise approximately 85,568m2 of floor space.

Public Domain

A foreshore link is proposed along the western edge of the Barangaroo site connecting the King Street Wharf Precinct in the south to the Headland Park in the north. The new foreshore link will be subject to a separate detailed Project Application(s) in the near future.

Since their establishment, the Technical Working Groups have met numerous times and three Implementation Plans/Strategies that are relevant to this Project Application have been prepared in consultation with these Technical Working Groups.

Further to this consultation, several of the specialists responsible for the preparation of the technical reports that comprise the appendices to this EAR have engaged in various consultations with relevant stakeholders, including the relevant utility providers.

3.2 Community ConsultationMore than 3, 000 people attended the display suite and month-long program of community forums aimed at providing direct public feedback into the ongoing design process for Stage 1 of Barangaroo. The objective of these forums was to encourage people from all over Sydney to provide feedback into the design and contribute ideas to ‘weave’ Barangaroo into the existing fabric of Sydney.

Over the month, the Barangaroo Delivery Authority also conducted a series of community events across Sydney, including the CBD, Parramatta and Caringbah. LL presented the Barangaroo Stage 1 development scheme and Peter Walker (of JPW) presented the Headland Park scheme. LL representatives also participated in the workshops presented as part of these events.

In addition LL has been running more intimate information events for local residents as part of its on-going community engagement program. As a result, hundreds of ideas, suggestions and comments have been fed directly into the design process for the site and have influenced the overall design rationale for Stage 1, including the location and configuration of the basement levels as proposed by this Project Application.

3.3 Ongoing ConsultationLL recognises the importance of positive relationships with all stakeholders and seeks to proactively engage with them over the duration of the Stage 1 project. A Stakeholder Consultation Strategy has been prepared (within the Environmental, Construction and Site Management Plan at Appendix O) which details how LL proposes to undertake stakeholder engagement to ensure all individuals and/or groups that have an interest in, or are affected by, the Project are consulted with.

Page 27: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

19JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

A strong commitment to an inclusive and pro-active community and stakeholder engagement process underpins this strategy. LL’s key objective to the ongoing consultation is:

To set the path for carrying out effective and meaningful consultation through an ‘early and often’ approach which incorporates stakeholder feedback into every stage of the project.

LL’s communications strategy has been devised with the following principles in mind:

An inclusive approach� – to implement inclusive community engagement processes, stakeholders must be provided with information that enables them to make informed decisions and to contribute in a meaningful (and informed) way. This includes providing the right amount of information in a timely way that is in plain English and consistent.

Transparent processes� – engagement processes should be transparent in order to develop trust and build strong relationships with the community. This means that information should be shared openly between stakeholders, where possible.

Community feedback� – engagement activities should be responsive as well as pro-active. This means that feedback should be an integral part of the process. Stakeholders should have the opportunity to provide feedback as part of the consultation process. This will assist in developing trust, ensuring communication flows in and out of the project team and that the community is kept informed of progress on the Project.

LL’s Stakeholder Consultation Strategy has been prepared to provide Lend Lease with the opportunity to;

recognise that LL’s business has an impact on communities and �other stakeholders;

be proactive in order to understand the needs of stakeholders and be in a �position to respond to these needs and meet them wherever possible;

provide accurate, up to date and accessible information to stakeholders as �early as possible and at regular intervals throughout the project;

be open, honest, fair and realistic in all dealings with stakeholders;�

treat the communities in which LL works with respect;�

recognise diversity and seek to inform all stakeholders of any decisions �affecting them;

ensure that all stakeholders and affected community members are well �informed about the Barangaroo development and can provide input into the project;

communicate LL’s intentions transparently in relation to Barangaroo;�

minimise impacts to affected residents and stakeholders; �

reiterate LL’s commitment to local employment and job creation, revitalised �infrastructure and improved quality of life for Sydney residents and visitors to Sydney; and

create a forum for exchange and information flow.�

4.1 Demolition Demolition of a number of existing structures on the Project Application Site will be completed under the existing approval for Demolition Works at Barangaroo, Sydney (MP 07-0077).

MP 07-0077, which was prepared on behalf of the Sydney Harbour Foreshore Authority, granted approval for the demolition of a range of existing structures within the Barangaroo site to prepare the site for future development as approved under the Barangaroo Concept Plan (refer to Section 1.1.3).

The works approved under MP07-0077 have been commenced but not completed. Demolition of the remaining structures approved under MP 07_0077 is proposed to commence in July 2010.

This Project Application seeks approval for the demolition of the following structures that were not included under MP 07_0077:

the concrete hardstand spanning the Project Application Site;�

any remaining existing structures, footings and hardstand required to be �removed to facilitate the proposed Margaret Street West street extension (refer to Section 4.7);

the substation located on the south eastern portion of the site adjacent to �Hickson Road;

the existing sand filled caisson sea wall located beneath the hardstand area �within the northern portion of the Project Application Site; and

22 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

4.2 Bulk ExcavationThe Project Application seeks approval for the bulk earthworks required to excavate the area to accommodate the basement car park, plant areas and ancillary areas as provided for by the approved Concept Plan.

It is estimated that approximately 350,000m3 of material will be excavated to enable the construction of the combined basement predominantly under Blocks 2 and 3. The excavation of the basement will reach a maximum depth of approximately -27 AHD. Excavation of bedrock will be required in the east and north east of the Project Application Site.

Retention systems are proposed to be installed prior to the bulk earthworks being undertaken. Groundwater control and retention systems are proposed to be installed to the proposed basement perimeters, and will typically be constructed with large piling rigs, and serviced by crawler cranes. These structures will be progressively anchored with the excavation works.

Conventional large excavation equipment, including excavators and bulldozers, are to be used. Excavation measures such as ripping equipment and/or hydraulic rock breakers will need to be used. The underlying sandstone exposed is expected to be largely within good quality Class IV or better sandstone.

Temporary de-watering of the site, also the subject of this Project Application, will be required to undertake the bulk excavation works.

Remediation works as outlined in Section 4.3, will be carried out in conjunction with the bulk earthworks.

4.3 RemediationThe purpose of the remediation works is to make the Project Application Site suitable for the proposed uses as envisaged by the approved Concept Plan. A Site Auditor’s Statement (Appendices H and K) advises that the Project Application Site is capable of being made suitable for its intended uses.

Any contaminated material will be remediated as required. Suitably treated and excavated material will re-used across the broader Barangaroo site to minimise the need to import fill for public domain works, and the creation of the Headland Park.

The treated material will be validated to ensure suitability for use at the Headland Park, or any other parts of the Barangaroo site as appropriate (subject to further necessary approval(s)). Temporary stockpiling may be required across the Barangaroo site to store excavated (and where relevant suitably treated) material. LL will work with the Department of Planning to confirm the exact location of temporary stockpiles prior to excavation works commencing on the site. Material unsuitable or unavailable for re-use on-site will be disposed off-site at a suitable waste management facility.

Although it is intended that treated surplus fill be transported to and placed at the site of the new Headland Park, this Project Application does not propose any land forming works associated with the creation of the Headland Park. Any land forming works for the Headland Park will be undertaken in accordance with MP10-0047 – Headland Park and Northern Cove Early Works, which is proposed to be submitted to the Department of Planning by the Barangaroo Delivery Authority in June 2010.

The Overarching Remedial Action Plan (prepared by ERM and attached at Appendix J) and the Remedial Action Plan, Barangaroo – Other Remediation Works (South) Area (AECOM, June 2010) (Appendix G) has been prepared in accordance with SEPP 55 and sets out the detailed methodology for remediating the Project Application Site to make the site suitable for the proposed uses under the approved Concept Plan.

set-up of decontamination stations and wheel wash zones at entrance and �exit points of the remediation enclosure.

A Site Auditor’s Statement will be obtained upon completion of the remediation works to verify the site is suitable for the proposed uses as envisaged under the approved Concept Plan. A detailed consideration of the remediation works and the RAPs is in Section 6.5.

Having regard to SEPP 33 and relevant guidelines, the remediation works are not considered to be a potentially hazardous industry(ies) as the works, in conjunction with the mitigation measures prescribed in the Overarching RAP and site specific RAP, are unlikely to pose a significant risk to human health, life or property or the biophysical environment.

4.4 Structural Works and Level by Level Description of Basement

This Project Application has been designed to facilitate early delivery of the Barangaroo Stage 1 development.

A combined basement is proposed as it allows for maximum design efficiency, and for vehicular circulation within the Stage 1 area to be rationalised to the greatest extent practicable. Rather than a series of separate basements, with separate vehicular ingress and egress points, a combined basement of the nature proposed allows for the number of vehicular accesses and crossings within the future public domain to be minimised.

As previously identified, the basement structure has been designed to both maintain flexibility with respect to the ultimate detailed design and distribution of the above ground floor space (commercial, residential and retail floor space); and to allow for expansion of the basement to occur in the future as required to support the GFA and land use mix of the Stage 1 development as it progresses.

The proposed basement structure has been designed based on an assumed GFA and land use mix that complies with the approved Concept Plan as identified at Section 4.5, and the resultant car parking demand generated in accordance with the car parking rates approved under the Concept Plan.

24 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The quantum of car parking proposed and the consequent size of the proposed basement structure is not influenced by the ongoing design process being undertaken for the towers and buildings that sit above, and as such the construction of the basement levels can proceed prior to those Applications being finalised.

The proposed basement structure has been designed to centralise plant and services required to support future development within the Stage 1 area. The plant and services areas have been located such that they are readily capable of servicing a variety of end building configurations, and have been sized and designed to support the maximum quantum of GFA and the land use mix for the Stage 1 development area approved under the Concept Plan.

4.4.1 FoundationsThe Project Application seeks approval for the necessary piling, caps and footings to support the basement car park as shown shown on the drawings at Appendix A.

4.4.2 Basement

Ground Level

The extent of the works proposed at Ground Level is limited to the ramps that provide access to the lower levels and to the surface road works described in Section 4.7.

Level B1A

This level accommodates a future car park entry, showers and lockers to service the residential, commercial and retail floor space above that will be subject to future Project Applications. It also includes areas for plant and storage, and loading docks. A substation and main low voltage switch room are also located at this level.

Level B1

A future blackwater treatment plant, plant and storage areas, loading docks, waste/garbage recycling area, and bicycle storage areas are located on Level B1. A small area of future retail GFA (subject to future Project Application approval) is also provided. Provision for a total of 2,200 bicycle / storage cages will be provided.

Levels C1 to C6 (inclusive)

Levels C1 – C6 accommodate the future 880 car parking spaces. The 880 car parking spaces shown at Levels C1 to C6 is an indicative parking provision (refer to Section 4.5 below). Support plant and equipment is located on each basement level.

4.5 ParkingThe Project Application seeks approval for up to 880 car parking spaces. Table 2 summarises the assumptions that the calculation of the 880 car parking spaces is based upon.

The final number of car parking spaces, and their allocation to specific uses / buildings will be determined as part of a series of future Project Applications relating to the above ground built form. It is proposed that each subsequent Project Application for Barangaroo (which requires the provision of car parking) will seek approval for an allocation and the operation of a specific number of car spaces out of the total 880 spaces proposed within the basement car park under this Project Application.

Page 33: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

25JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The operation of the car parking spaces will therefore commence in stages following approval of each of the relevant Project Applications that propose allocation of the spaces to approved GFA. The approved allocation of parking will always remain consistent with the car parking rate approved under the Concept Plan.

The proposed car parking spaces will not be utilised for commercial or other parking purposes until the construction and occupation of the commercial, retail and/or residential buildings.

It is proposed as part of this Project Application that the basement car park will be used temporarily for construction related activities (but not parking), facilities and accommodation until such time as it is required to facilitate operation of the commercial, retail and residential development.

The proposed quantum of parking area has been calculated on the approximate number of car spaces that has been identified as required to support the built form in accordance with the approved Concept Plan (as modified).

Retail 30,000m2 63

Commercial 277,900m2 463

Total 880

4.6 Loading DockA major loading dock is proposed to service the Stage 1 area with multiple points of vertical connection to both the ground level and to each of the future buildings above the basement.

The proposed design / layout of the loading dock provides good efficiency in terms of the layout, manoeuvring space and the ability for different sized truck spaces to be managed for appropriate uses. Additional loading docks will be associated with residential lift cores in other locations, and will be subject to future Project Applications.

The loading dock will be a fully shared facility with managed time of arrival. The loading dock makes provision for five (5) garbage compactors, 26 truck and van docks and 10 courier spaces. Additional spill-over courier spaces, 10 motorbike spaces and up to 46 bicycle courier spaces are also available.

The loading dock will be accessed via the Margaret Street West entry and controlled by a dock controller. There will be on-site personnel who would manage the loading dock area, monitoring and managing delivery vehicles on entry to the site.

4.7 Road WorksThe Project Application seeks approval for a range of road works associated with the future development of Barangaroo. The works, which are shown in Figure 5 below, comprise:

the extension of Margaret Street West;�

the extension of Lime Street;�

temporary vehicular access from Hickson Road; and�

vehicular access from Margaret Street West.�

Margaret Street West will be constructed in its final alignment through to Lime Street allowing closure of the existing diagonal connection between Shelley Street and Lime Street.

The proposed road works may require approval under Section 138 of the Roads Act 1993 from the appropriate roads authority, which in this case is the City of Sydney Council, particularly in relation to:

the erection of any structures or the carrying out works in, on or over any �public road(s);

digging up or disturbing the surface of a public road(s);�

removing or interfering with a structure, work or tree on any public road(s); or�

connecting a road(s) (whether public or private) to a classified road.�

LL will obtain the required approval(s) under the Roads Act, 1993 from the City of Sydney prior to commencing the proposed road works. It should be noted that any required approval under Section 138 of the Roads Act, 1993 cannot be refused if it is necessary for carrying out the project and is required to be substantially consistent with the Project Application approval (refer Section 75V(1) of the EP& A Act).

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

4.8 Vehicle AccessUltimately, two vehicle entrances are proposed to provide access to the basement carpark.

The first is on Hickson Road and will provide ramp access to Level B1. This access will serve as the final vehicular access point to the basement car park (see Figure 5). However, this road is located within the DECCW declared area to the north of the Project Application Site (within Block 4) which is required to be remediated prior to any development proceeding. The design and construction of this access road will therefore be subject to a separate future Project Application.

This Project Application includes a temporary road to be constructed to connect the spiral ramp in the north east corner of the basement to Hickson Road. The ramp will provide access to the residential, retail and commercial car parking levels which are located along the Hickson Road alignment.

Roller shutters or other barriers will secure this ramp until the operation of the car park is approved under future Project Applications. The lower section of this ramp is shown on Drawing BB1_PA1_A0006. The upper section of the ramp is detailed in Drawing BB1_PA1_A005.

Details relating to all aspects of the operation of the car park will be submitted with the future PAs (and updated sequentially as necessary).

The other vehicle entrance is located at the western edge of the proposed Margaret Street West extension, which will be accessed from Hickson Road. This entrance leads directly to the loading dock (see Section 4.6).

Figure 6 – Initial Vehicle Access Plan (including temporary access) Source: ARUP

4.9 Pedestrian AccessProvision for a number of lift cores and associated lift lobbies has been made in the basement levels. Lift cores and lift lobbies are located throughout the car park, providing access to Blocks 2 and 3 above, and are indicatively shown in the attached architectural drawings (Appendix A).

The parking spaces have been indicatively allocated in zones to correspond with the various lift core access points for convenient and safe access by residents and employees.

Page 36: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

28 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

Pedestrian access around the site during works and up to the completion of the construction will be restricted within the Project Application Site.

The detailed design of the interface between the car park ramp / access points and the future public domain will be the subject of future Project Application(s) that seek approval for the public domain and will be in accordance with the Public Domain Plan that is to be prepared in consultation with the Technical Working Groups. The detailed design of the car park ramps will consider pedestrians and pedestrian safety, and measures such as mirrors / warning systems etc will be included.

4.10 Safety, Security and LegibilityCCTV monitoring will be provided throughout the car park, with coverage in particular to lift lobbies, loading docks, and vehicle entry and exit points.

Furthermore, a loading dock manager will be located at the bottom of the loading dock access ramp to control access to the loading docks. The access ramp will have a roller shutter that will be closed out of hours for safety.

The car park access will be controlled by roller shutter doors.

Details relating to way finding signage within the basement will be provided as part of the documentation accompanying the Project Applications for each relevant building to ensure that the circulation and parking arrangements are legible for both permanent occupants and visitors. External way finding signage relating to the basement carpark entrances (both vehicular and pedestrian) will be documented in the future detailed Project Applications to ensure that circulation and access within the Stage 1 development area is legible.

4.11 Environmental, Construction and Site Management

An Environmental, Construction and Site Management Plan (ECSMP) has been prepared by Bovis Lend Lease in association with Cardno and is located at Appendix O. The ECSMP incorporates the recommendations made in the expert consultant reports prepared to accompany this Application and addresses the necessary environmental, construction and site management relating to:

the establishment of appropriate environmental protection structures;�

demolition of existing ground slabs and the grubbing and demolition of �existing below ground foundations and structures;

tree clearing;�

decommissioning and capping off of existing services and relocation �where required;

soil remediation – treatment of contaminated soils excavated as part of the �bulk earthworks;

construction of basement perimeter retention structures;�

basement construction;�

potential concrete crushing and screening operations;�

loading and hauling of fill materials excavated from the basement to the �proposed Headland Park at the north of the site;

where required, classification and off-site disposal to licensed landfill of �excavated fill materials deemed unsuitable for re-use; and

de-watering operations, including water treatment where required.�

29JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

A Construction Traffic Management Plan (CTMP) (see Appendix Q) has been prepared by ARUP. The CTMP identifies truck access routes and construction traffic management measures proposed.

Waste Management

A Waste Management Plan has been prepared by ARUP which is included at Appendix R. Waste storage has been planned so that residential, commercial and retail waste can be stored separately. Also, wherever possible, recyclables and general waste are planned to be stored in separate rooms to ensure waste streams are not inadvertently mixed.

Detailed waste management plans for each future building confirming the assumptions in the Waste Management Plan accompanying this Project Application will be submitted with the relevant Project Applications. The proposed basement waste storage areas have been designed on the basis that waste will be managed in accordance with the following principles:

Residential waste:

Occupants from residential blocks will place their general waste down a �waste chute which will enable waste to be collected in waste storage rooms within the basement;

Occupants from residential blocks will place their recyclables within �recycling bins provided within storage areas on each floor. These recyclables will be collected by building management and transported via lifts to basement storage;

Waste chutes may be provided, the details of which will be provided in �future applications; and

A compactor for general waste will be provided.�

Commercial and retail waste:

General waste will be stored in a dedicated waste storage room(s);�

Retail wet waste will be stored in a separate semi enclosed area(s);�

Recyclables will be stored in dedicated recyclables waste storage room(s); and�

Compactors will be provided for the general waste and cardboard/paper �waste; waste collection will be undertaken by a private contractor once a day.

The waste management areas within the proposed basement have been designed and sized to accommodate the demand anticipated to be generated by approximately 30,000m2 retail GFA, 277,900m2 commercial GFA and 312 residential apartments.

Construction Hours

It is proposed to undertaken construction between the hours of 7.00am and 8:00pm Monday – Friday and between 7:00am and 5:00pm on Saturdays. No work will be undertaken on Sundays or Public Holidays, except in the limited cases identified below.

It is noted that the proposed hours are outside DECCW’s standard hours of construction. However, this extended period will enable the activities to be carried out in a more efficient manner, thereby shortening the overall construction period.

It is also noted that some activities are required to be undertaken outside normal construction hours, for example dewatering and treatment of groundwater, dust suppression, attendance of environmental protection structures, and other site and maintenance activities.

Page 38: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

30 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The works and the specific activities to be undertaken during the periods outside DECCW standard construction hours include concrete finishing processes, maintenance, materials handling/deliveries and other relatively quiet activities. Loud activities such as sheet piling, excavator mounted hammers and major earthmoving equipment are not proposed.

Dewatering and soil and groundwater treatment plant would need to operate on a 24 hours per day basis to clear groundwater from the site.

Out of hours works would be undertaken in emergency situations to ensure safety is maintained.

Temporary Structures

A number of temporary structures are required on the Barangaroo site to facilitate the construction works.

Concrete Crushing Plant

A concrete crushing and screening plant is proposed to process the concrete waste from the demolition of the ground slabs within the Project Application Site. The proposed location of the crushing plant as well as associated stockpiles is as shown on drawing DA-025 appended to the ECSMP at Appendix O.

As a preferred option in line with the goals of the Waste Management Plan (Appendix R), demolished concrete will be crushed on site for future use in the Headland Park in applications such as drainage media. Likely other uses may include temporary roads and select fill material. If in the unlikely event that concrete crushing does not occur on the site, the demolished and crushed concrete may be transported off-site to a licensed crushing facility. Off-site transport will likely generate in the order of 10-15 truck movements per day for a period of approximately 10-12 weeks.

Hoardings / Site Fences

The construction site will be secured by a combination of hoardings and fencing, as described in Table 3 below.

Table 3 – Proposed construction hoardings/ site fences

Frontage Proposed Fencing

Hickson Road A Class B painted hoarding along Hickson Road Work extending north from the Margaret Street intersection. Vehicle gates will be located at the northern end of Stage 1 for access to and from site, to coincide with existing crossovers associated with the former Port use. This area will be secured by gatemen and stop/go personnel to control pedestrian and vehicle traffic.

Shelley Street Shelley Street will be protected by chain wire, barbed fencing covered with shade cloth. Personnel security turnstiles will be located along this frontage for access to site until this part of the site is redeveloped by the extension of Margaret Street West.

Western Frontage (along the Promenade)

Class A 2.4m painted plywood hoarding or chain wire that bounds the site mesh/barbed fence will be erected along the Western Frontage to maintain the public thoroughfare through to King Street Wharf.

Northern Frontage Class A painted hoarding of minimum 2.4m height.

Appropriate logos and other artwork will be located on the hoardings/fencing in consultation with the Department of Planning and Barangaroo Delivery Authority.

4.12 Building ServicesThe indicative services within the proposed basement are summarised below, with further detail provided in the Infrastructure Concept Plan prepared by ARUP (refer Appendix S. The final services will be designed to achieve the level of performance required by Blocks 1-4 and the Ecologically Sustainable Development (ESD) strategies and the overall ESD strategy for the site.

Mechanical Services

A mechanical ventilation system will be provided to provide exhaust and supply air systems. In order to reduce the electrical consumption of the basement area, the car park supply and exhaust ventilation system will incorporate variable speed fan drives controlled by CO and NO2 sensors as appropriate.

Utilities and Services Provision

Infrastructure upgrades are being developed with the relevant infrastructure providers for the entire Barangaroo site. As a result, the detailed design of long term services has not been resolved at this time.

This Project Application therefore makes provision for in-ground services and utilities below basement slabs and road verges.

An Infrastructure Concept Plan detailing the proposed site-wide upgrades required is located at Appendix S and can be summarised as follows:

Water services: � a water extension main from the 300mm Sydney Water supply in Hickson Road is proposed. Final routing and locations are to be agreed with Sydney Water during detailed design and following modelling of the network. A separate non-potable water service shall be provided from the blackwater treatment plant to each building to target water consumption reductions.

Sewer services: � provision is being made for a blackwater treatment plan, to be located within the vicinity of the existing sewage pumping station. Discussions are in progress with Sydney Water to confirm the capacity of the existing pumping station and the feasibility for the pumping station to be sewer mined to provide additional capacity that can be treated and reused by the black water treatment plant.

Electrical services:� Energy Australia has advised that electrical supply will be provided from the new City North Zone Substation located on the corner of Erskine Street and Sussex Street. Feeders will be reticulated along Sussex Street and Hickson Road to the Substation. It should be noted that substations will also be provided within future individual buildings, which will be supplied from the feeders identified above.

Telecommunications Services: � extensive upgrades of the surrounding telecommunications systems will be required. LL is working with telecommunications providers to develop appropriate concepts and technologies to meet the expected demands of the future development.

Gas Services: � The existing high pressure main will require extending to provide sufficient gas for the Project Application site. New gas mains will be reticulated within future roads to be constructed under separate Project Applications.

Chilled Water Services: � Provision is being made within the basement for a centralised chiller plant and Harbour heat rejection plant from which chilled water shall be reticulated to future individual buildings. This strategy is being developed further as part of the design.

32 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

Fire ServicesThe fire safety of the basement areas will be developed to meet the Performance Requirements of the Building Codes Australia. This will be achieved either through compliance with the BCA’s Deemed to Satisfy Provisions or through performance based fire engineering design where necessary.

Lighting

Internal lighting will be provided throughout the car park in accordance with AS1680. This lighting will incorporate energy efficient lamps and a controls system that includes timers and occupancy sensors. Emergency and exit lighting will be designed in accordance with AS2293.1 and the BCA.

Site Stormwater Infrastructure

The locations of the existing stormwater pipes which traverse the site are not compatible with the proposed works.

Accordingly the Project Application seeks approval for the construction of in-ground stormwater infrastructure and temporary diversion of the existing stormwater infrastructure as shown on the Stormwater Concept Plan at Appendix T and Figure 7.

Figure 7 – Stormwater Concept Plan Source: ARUP

Other than the removal of existing pipes through the proposed Basement area, and their replacement temporarily, the design shall ensure that there is no negative impact on surrounding neighbours relating to the existing overland flow paths through and around the perimeter of the Stage 1 site. Details are to be developed and integrated into the ground plane design and detailed in future Project Applications.

4.13 Ecologically Sustainable DevelopmentAn overview of the significant sustainability principles and targets for the whole Barangaroo site and Stage 1 precinct are located in the ESD Report at Appendix U. The realisation of these targets will be delivered progressively throughout the Stage 1 development phase. Consequently the subject Project Application should be considered in context with the sustainability aspirations of the broader Stage 1 development.

In particular the following ESD initiatives will be incorporated into the construction and operation of the Project Application:

Page 41: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The� basement is capable of supporting buildings which will achieve a NABERS 5 star and a minimum of 5 star Green Star building ratings.

The basement provides spatial allocation for a future precinct blackwater �plant. This plant will be designed to a capacity that allows a water positive outcome.

The basement provides a range of plant rooms for a centralised chilled water �plant, harbour water cooling, and electrical infrastructure.

The� basement will incorporate the following waste management initiatives:

waste- collection areas in the basement have been provided allowing for the streaming of recyclables;

where possible material excavated from the Basements is proposed to be - reused at the site of the proposed Headland Park;

on-site concrete crushing is proposed as a means of recycling demolition - waste prior to reuse in creating the Headland Park;

waste minimisation and recycling practices will be adopted during the - demolition and construction phases of the basement works;

contaminated groundwater is proposed to be collected, treated and - reused for dust suppression where appropriate; and

car parking rates and numbers in accordance with the TMAP which - reduces the amount of cars associated with the development compared to normal Sydney CBD practice.

4.14 StagingThe expected sequencing of the works will be undertaken over a two year period approximately as follows:

Oc� tober 2010 - March 2011: Piling and retention system construction, including excavation of approx 24,000m3 of material from the site;

February 2011 – January 2012: Excavation of approx 335,000m� 3 of material which will typically stay on site and be transferred to the proposed Headland Park. Approximately 3,000 m3 of contaminated material may be removed from the site following remediation treatment; and

Octobe� r 2011 – December 2012: Construction of concrete columns and slabs for basement car park and loading dock area.

The construction timing for each phase of the works described and the Headland Park works will run concurrently as shown in the following chart at Table 4. It should be noted that the Headland Park works are covered by MP10_0047 and will be carried out by a contractor separately commissioned by the Barangaroo Delivery Authority.

Construction staging plans for the proposed works are appended to the ECSMP which is located at Appendix O.

Major Development SEPP The Barangaroo site is listed as a State Significant Site under Part 12 of Schedule 3 of the Major Development SEPP. The SEPP zones the Project Application Site part B4 Mixed Use and part RE1 Public Recreation. The proposed earth works and basement are permissible in both zones with development consent.

SEPP 33 The remediation works as described in Sections 4.3 and 6.5 are not considered to be a potentially hazardous industry(ies) as the works, in conjunction with the mitigation measures prescribed in the Overarching RAP and site specific RAP, are unlikely to pose a significant risk to human health, life or property or the biophysical environment.

SEPP 55 A Remediation Action Plan has been prepared for the site in accordance with SEPP 55 (see Appendix G). Following the necessary remediation works, the site will be suitable for the proposed uses.

Sydney Regional Environmental Plan (Sydney Harbour Catchment) 2005

Barangaroo is located within the boundaries of the Sydney Harbour Catchment and as such is subject to the provisions of Sydney Regional Environmental Plan (Sydney Harbour Catchment) 2005 (Sydney Harbour REP). The Sydney Harbour REP aims to provide a clear and consistent planning framework to protect and enhance the unique attributes of the Harbour. The Project Application is consistent with the SREP as it will provide the first step in facilitating the delivery of Barangaroo which will create a healthy and sustainable waterway environment and promoting recreational access to the foreshore and waterways.

Sydney Harbour Foreshore and Waterways Area Development Control Plan

The Sydney Harbour Foreshore and Waterways Area Development Control Plan (the DCP) complements Sydney Harbour REP and provides more detailed design parameters for development within the foreshore area of Sydney Harbour.The proposal is generally consistent with DCP.

6.2 Consistency with the Barangaroo Concept Plan

The Project Application seeks approval for the carrying out of excavation, construction of the basement levels to accommodate up to 880 car parking spaces, and associated servicing and infrastructure works. The Project Application does not seek approval for the detailed layout and operation of car parking spaces, loading dock and servicing areas, or for other uses within the basement levels.

The detailed layout and operation of the basement levels will be addressed in a series of future Project Applications relating to the built form ultimately proposed above the basement areas. Notwithstanding this, an indicative layout has been designed and the car parking rates that have been approved by the existing Concept Plan (as modified) have been adopted to demonstrate that the proposed basement levels will adequately accommodate a suitable provision of car parking in relation to the GFA and land use mix of the approved Concept Plan.

The Project Application has been designed to facilitate early delivery of the first stage of the overall development on the site.

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The proposed basement car park and associated plant and services has been specifically and carefully designed to allow works to commence whilst maintaining maximum flexibility until such time as the detailed design and distribution of the above ground floor space (commercial, residential, community and retail floor space) is finalised.

Particularly, the building core locations, car parking rate and provision, and pedestrian and vehicular access arrangements (including lifts and fire stairs) are not influenced by the ongoing design process being undertaken for the above ground buildings, and as such the construction of the basement levels can proceed prior to those Applications being finalised.

Importantly, the excavation and construction of basement levels is consistent with the approved Concept Plan (as modified). Modification B3 of the Concept Plan approval requires the new Southern Cove to be enlarged beyond the approved location of the proposed Globe Street. The enlargement of the Southern Cove water intrusion in conjunction with the planning and design requirements imposed by Modification B3, have consequently provided LL with the opportunity to further reconsider the overall master plan for the site, including the configuration of the internal street and public domain networks, arrangement of land uses across the site, and the distribution of the approved GFA and heights across the entire site (to be detailed in future Project Applications to be submitted shortly).

Modification C1 of the Concept Plan approval permits the redistribution of any GFA between Blocks 2, 3, 4 and 5, that is displaced by the encroachment of the enlarged Southern Cove (Modification B3), as long as the total GFA permitted on those blocks is not exceeded. This current Project Application is a direct response to the combined effect of Modifications B3 and C1 and accordingly is complying with the terms of the Concept Plan approval. The Project Application is therefore consistent with the Concept Plan as currently in place.

The Project Application is also consistent with the approved Concept Plan Statement of Commitments (see Appendix V).

6.3 Traffic, Transport and AccessTraffic, access and parking impacts have been assessed by ARUP. A copy of their reports – a Supplementary TMAP; a Traffic and Parking Report; and a Construction Traffic Management Plan – are respectively attached at Appendices E, D, and Q and are summarised below.

6.3.1 Traffic GenerationAlthough seeking approval for up to 880 car parking spaces on the site, the proposed development does not seek consent for the operation of any parking spaces on the site to commence, and therefore there will be limited vehicle movements until the future commercial, residential and retail buildings (subject to other Project Applications) are approved, constructed and occupied.

In the context of the existing traffic flows on the surrounding street network, ARUP has assessed the resultant peak hour traffic generation of the site as a whole to be relatively small. The traffic generation of the site is constrained by a low parking provision rate for commercial, residential and retail uses adopted under the approved Concept Plan.

As referenced in the TMAP dated September 2008, a Paramics model of the Sydney CBD was utilised to test traffic options with different trip generations and traffic management measures for the completed Barangaroo development. The modelling demonstrates that traffic operation will continue to be reasonable post development of the Concept Plan, however average speeds will be lower. As a result of the indicative modelling, it can be concluded that the proposed car parking arrangements (once operational) will operate without overloading the local road network.

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

6.3.2 Access and Circulation The proposed Margaret Street West extension and the Hickson Road basement access arrangements have been designed generally in accordance with the applicable City of Sydney and RTA accepted standards. A right turn bay is required at the Hickson Road access to allow for turning movements with respect to the proposed temporary access. This traffic arrangement will be subject to consultation with the City of Sydney. The permanent access will be the subject of a future Project Application following remediation of the DECCW declared site. Preliminary modelling indicates that the right turn bay complements current traffic management arrangements, particularly as Hickson Road speed limits in this area are restricted by existing traffic calming measures.

Discussions are in progress with NSW Maritime, as the relevant landowner, regarding the detailed design of the Margaret Street works. These works may require road opening/closure permits, which LL will obtain prior to commencement of these works.

The loading dock and all access ramps have been designed in accordance with AS2890.2- 2002 – Off-street commercial vehicle facilities. A series of truck turning manoeuvres have been tested utilising AutoTrack to confirm that the basement will provide good levels of access for all truck sizes from courier cars up to 12.5m long heavy rig vehicles.

The construction of a combined basement carpark beneath the future development provides for a significantly enhanced level of efficiency in carpark design, and allows for vehicular circulation within the Stage 1 area to be rationalised to a high degree. Rather than a series of separate basements, with separate vehicular and pedestrian access arrangements, the proposed combined basement allows for the number of vehicular access points and crossings within the public domain to be minimised. This supports the creation of a pedestrian oriented public domain.

6.3.3 Car ParkingAs outlined in Section 4.3, the Project Application seeks approval for up to 880 car parking spaces.

The proposed number of car parking spaces complies with the relevant parking rates under the approved Barangaroo Concept Plan, based on an assumed development comprising 30,000m2 retail GFA, 277,900m2 commercial GFA and 312 residential apartments.

Whilst the final number, layout, allocation and operation of the proposed car parking spaces will be the subject of a series of future Project Applications, this Project Application recognises that the parking policy for the Barangaroo site should support public transport and other non-car modes of transport. Low car parking provision is also important in ensuring the CBD’s existing road network is not compromised through potential traffic generation.

By way of comparison, the City of Sydney commercial parking rate prescribed by the Central Sydney Local Environment Plan 2005 is 1 space per 340m2 GFA. Application of that rate would necessitate 817 spaces for the future commercial floor space alone.

The proposed provision of commercial car parking in this Project Application is (as required by the approved Concept Plan) represents a much stricter provision of commercial car parking than that permitted elsewhere in the Sydney CBD. The indicative 463 commercial spaces proposed, represents 354 less spaces than would otherwise apply if the City of Sydney Council standard commercial car parking rates were applied to the land area within the B4 zone.

The proposal therefore improves upon the City of Sydney’s car parking rates for commercial development. The Sydney City Council’s existing parking rates under Sydney LEP 2005 for residential development have also been adopted as required by the approved Concept Plan.

Page 48: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

40 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The proposed car parking provision is entirely consistent with the rates identified in the approved TMAP (dated September 2008) and supports the 4% car mode share outlined in the approved Concept Plan.

6.3.4 Loading DocksBasement Level B1 includes 26 truck bays. These truck bays are to be controlled by the loading dock manager, and the majority of deliveries would be prearranged. These measures have been assessed by ARUP and have been found to be adequate.

Furthermore, ARUP has undertaken a turning path analysis of the loading bays within Basement Level B1A and B1. The available manoeuvring space is considered satisfactory.

6.3.5 Construction Traffic Management ARUP has prepared a Construction Traffic Management Plan (CTMP) (see Appendix Q) for the proposed works. The CTMP assesses the likely construction traffic generated during the initial stages of the development of the site and its likely impact to the road network. Pedestrian safety and amenity issues during the construction of the proposed works have also been considered. The assessment concludes that the construction related traffic impacts arising from the works proposed can be appropriately managed.

Traffic Generation

ARUP estimates that the proposed development will generate the following traffic movements during the construction period:

Morning Peak Hour 8-9 am, 11 visitor cars in, 20 trucks in, 1 trucks out.�

Afternoon Peak Hour, 5-6 pm, 11 visitor cars out, 1 trucks in, 20 trucks out.�

Some of the elements of the excavation and basement construction works proposed will overlap and be carried out at the same time (refer to Table 4). The maximum truck movements for each phase of construction works will be as follows:

Site establishment and demolition�

average of 24 truck movements per day -

maximum of 73 truck movements per day -

maximum of 7 truck movement per hour-

Piling and retention System Construction �

average of 30 truck movements per day -

maximum of 40 truck movements per day -

maximum of 5 truck movement per hour -

Bulk excavation – removal of treated contaminated material from the site�

average of 8 truck movements per day -

maximum of 16 truck movements per day -

maximum of 2 truck movement per hour-

Bulk excavation – transfer of excavated material to Headland Park �

maximum of 30 trucks arrive on site in the morning and stay on site all - day before departing in the afternoon

Bulk excavation – transfer of excavated material off the site�

in the order of 15 trucks per day arriving and leaving the site throughout - the day

Concrete columns and slab construction �

average of 30 truck movements per day -

maximum of 100 truck movements per day -

maximum of 10 truck movement per hour-

A comparison of the existing and forecast intersection performance at peak hours based on the estimated traffic generation and truck access routes demonstrates that the construction traffic will not affect the level of service (LOS) at any of the key intersections identified (see Table 7).

It is noted that it is not the intention of LL to transport any contaminated materials from the bulk excavation and basement works via Sydney Harbour. Therefore there will be no navigation or safety impacts on other water based traffic and ferry commuter services.

Truck Access Routes

Where possible, existing gates will be utilised to minimise the impacts on existing parking and traffic arrangement within Hickson Road. In order to ensure that safe access is achieved, Traffic Control Plans will be prepared by RTA accredited contractors. Trained and licensed Traffic Controllers may also be used to assist with truck manoeuvring into and out of the traffic stream (refer to Draft Statement of Commitments).

Construction and Pedestrian Traffic Management

The proposed worksite frontage pedestrian / work zone (see Section 4.11) will maintain a safe pedestrian access corridor adjacent to the works at all times along the western side of Hickson Road.

The proposed site hours of operation of 7am – 8pm on weekdays will mean that the majority of site traffic movements are generated outside the normal commuter peak traffic periods, such that their impacts on the surrounding road network are minimised.

Existing and forecast pedestrian activity along Hickson Road is anticipated to remain, particularly when the Temporary Cruise Passenger Terminal is in operation. Safe pedestrian access along the western side of Hickson Road will need to be provided. Hoardings and fencing is proposed to assist with pedestrian safety. A safe pedestrian refuge crossing is recommended to be constructed within Napolean Street to facilitate pedestrian movements on the eastern side of Hickson Road, which may be an attractive alternative to walking adjacent to the construction site (refer Section 6 of the Construction Traffic Management Plan at Appendix Q). This will be subject to consultation with the City of Sydney.

Page 50: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

42 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The CTMP makes a number of recommendations regarding traffic control:

The site traffic control recommendations for each worksite gate entry or exit �point (including all appropriate signage) should be determined by means of a “Traffic Control Plan” to be prepared by an RTA accredited contractor.

Each site entry and/or exit gate number and the name or other description �of its proposed activity should be clearly signposted for the benefit of all approaching site traffic, in particular emergency services vehicles.

The vehicular traffic movements at each of the site entry or exit gates for �traffic to and from Hickson Road will potentially need to be controlled by a flagman to ensure no potential traffic safety conflicts occur between the site truck traffic and pedestrians on the adjacent footpath.

The project will be carried out in conformance with Appendix Q and accordingly the above recommendations have been incorporated into the draft Statement of Commitments.

Bus and Emergency Vehicle Operations

ARUP has concluded that the proposed works and truck movements are unlikely to have any adverse impact on bus services, bus operational requirements or emergency vehicle access.

6.3.6 Metro Rail CorridorThe proposed development will not impede the Metro rail corridor or affect the future operations of the CBD Metro project. Refer to Metro Interaction Report prepared by ARUP at Appendix W.

The basement entry ramp will pass over the Metro rail corridor before further ramping down to lower basement levels. This entry ramp is located approximately 12-15 metres above the top of the proposed Metro tunnels. It will be constructed as a suspended concrete structure so as to ensure that any future excavation works for the Metro will have negligible impact on the ramp.

It is proposed that the basement slabs and podium ground plane slab, together with the future above ground structure, coordinate with and are supported by the Metro Station and Service Box structure.

6.4 Visual AmenityThe architectural drawings at Appendix A demonstrate the basement car park and basement areas are wholly contained below ground level which will allow for future Project Applications to provide public streets with a high quality public domain.

The entry and exits to the basement car park are located at the road level and will therefore have no detrimental impacts on the visual amenity of the area.

A range of temporary structures such as the site offices were approved as part of a separate Project Application (MP 07_0077). The location of these structures is confirmed under this Project Application for approval.

Site hoardings and fences will be screened to add visual interest wherever possible.

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

6.5 Remediation of Contaminated MaterialThe Overarching Remedial Action Plan for Barangaroo prepared by ERM (Appendix J) and Remedial Action Plan Other Remediation Works (South) Area prepared by AECOM (Appendix G) establish the endorsed remediation activities for Stage 1 of the Barangaroo development including the Project Application Site. The proposed remediation works will be undertaken in conformance with these two RAPS and the detailed HHERA.

The preferred remediation strategy for the Project Application Site is to remediate the contaminated soil which is either a source of groundwater contamination and/or a risk to human health. Therefore the remedial process is focused on soil remediation technologies. Active groundwater remediation is not currently proposed as the groundwater contamination will be addressed by removing the contaminated soil.

The treatment of contaminated material is proposed to be ex-situ solidification or stabilisation of materials. Chemical additives will be blended into the contaminated soil to reduce its toxicity and limit solubility and mobility. This is a proven method of treating a broad range of contaminants including petroleum hydrocarbons, PAHs and metals.

The re-use of treated materials (where suitable) within the broader Barangaroo site will be cost effective and deliver significant environmental benefits including:

minimising waste disposal to landfill;�

minimising CO� 2 emissions through reduced transport requirements;

reducing the amount of imported fill; and�

helping minimise the carbon footprint of the overall Barangaroo �re-development.

Temporary stockpiling may be required across the Barangaroo site to store excavated (and where relevant suitably treated) material. LL will work with the Department of Planning to confirm the exact location of temporary stockpiles prior to excavation works commencing on the site. Unsuitable treated material will be disposed off site to a licensed landfill operator.

The HHERA referred to in Section 4.3, will be prepared prior to commencement of construction works and set Site Specific Target Criteria (SSTC) for the remediation of contaminated material. The SSTC will:

define soil concentrations that will not represent an unacceptable risk to �human health or the environment if left in-situ at the site or incorporated elsewhere into the Barangaroo development;

define groundwater concentrations that will not represent an unacceptable �risk to human health or the environment;

establish standards for quality of material proposed to be used on the site or �other areas of Barangaroo; and

establish if any treatment is required to achieve relevant standards.�

The Remedial Action Plan Other Remediation Works (South) Area and the Overarching RAP have been reviewed by accredited Site Auditors, who have provided preliminary comments on the suitability and appropriateness of the planned remediation. The Site Auditors’ respective reviews of the Remedial Action Plan Other Remediation Works (South) Area and Overarching RAP is included at Appendix H and Appendix K. The Site Auditors’ reviews found:

the assessment of remedial options in the RAPs was adequate;�

the preferred ex situ stabilisation and solidification remediation options and �rationale are appropriate;

Page 52: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

44 JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

the validation sampling approach is reasonable, however the frequency of �sampling required will depend upon the results obtained and their consistency;

a groundwater monitoring plan should be prepared; and �

the site management plan and contingency plan measures are �considered appropriate.

The Site Auditors have concluded that the remediation and validation approach is generally appropriate and that the level of detail in the RAP is appropriate for the current stage of the remediation planning process. The Site Auditor for the Remedial Action Plan Other Remediation Works (South) Area also considered that the RAP strategies contained within that RAP are generally consistent with the Overarching RAP. The preparation of the HHERA, SSTC, RAP Addendum and RWP has been incorporated into the draft Statement of Commitments.

6.6 Hydrology and Water ManagementA Water Quality Report (Appendix X) has been prepared by Worley Parsons to specifically address the DGRs relating to the potential Hydrology and Water Management issues associated with the development. The project will be carried out in conformance with Appendix X.

6.6.1 Water Quality ImpactsIt is not expected that the proposed works will result in any significant water quality impacts in Sydney Harbour given:

the works will be carried out landward of the existing outer sea wall; and�

once the basement retention systems are constructed, they will limit and �act to control any movement of groundwater between the construction area and the Harbour. Water quality risks will therefore be negligible once construction of the retention systems has been completed.

However, the report does identify the potential for water quality impacts associated with the earthworks, such as material stockpiles, silt and dust may have sedimentation impacts; and dewatering. To manage the potential sedimentation and dewatering impacts the following water quality management, mitigation and monitoring measures can be implemented in accordance with best practice. The measures, which are detailed in the Water Quality Report include:

Appropriate excavation methods�

Turbidity (silt curtains)�

Erosion and sediment control measures�

Dewatering and water treatment (It is proposed to collect and treat (to the �standard required) the water that will infiltrate the excavation before it is discharged into the stormwater or sewer system).

Routine visual inspections�

Water quality monitoring �

Monitoring weather and tides�

Details of the water quality monitoring program proposed are also contained in the Water Quality Report.

45JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

6.6.2 Estuarine Water Quality and Aquatic EcologyAn assessment of the impacts of the proposal on the estuarine water quality and aquatic ecology (at Appendix X) demonstrates that the bulk excavation and the basement works are unlikely to have any direct interaction with the water or bed of the Harbour if undertaken in conformance with Appendix X as:

all works will be undertaken on land that is set back from the existing �caisson walls and the rock embankment beneath the existing wharf; and

the majority of the excavation and remediation works, which have the �greatest potential to cause impact to the water and the Harbour, will largely be undertaken upon completion of the basement perimeter retention systems.

The Report does identify that there is a low risk of groundwater or sediment movement through or under the shoreline structures during construction of the basement retention systems because these are set back from the existing foreshore alignment. The Report recommends that the detailed design of the retention systems consider and minimise any potential for disruption to the gravel foundations below the caisson structures. It is further recommended that a silt curtain be used during construction of the basement retention system structures.

The Report also notes that:

No marine vegetation was observed during the marine ecology study. �

There will not be any impacts on estuarine circulation or changes to �hydrological regimes in the surrounding harbour waters.

The Estuarine foreshores will not be altered as part of the Project Application.�

6.6.3 StormwaterA Stormwater Concept Plan has been prepared by ARUP for Stage 1 which illustrates the proposed works (see Appendix T). The design will minimise negative impacts on surrounding neighbours relating to the existing overland flow paths through and around the perimeter of the Stage 1 site. The final design of the stormwater infrastructure will be developed and integrated into the ground plane design as part of subsequent Project Applications.

Whilst not directly relevant to the subject Project Application, it should be noted that all stormwater falling on the Barangaroo site is typically to be either reused via building based rainwater tanks or alternatively treated to National Best Practice with an integrated approach to Water Sensitive Urban Design (WSUD) before being discharged into the Harbour. This will include:

removal of litter and gross pollutants from stormwater running into �the Harbour;

a reduction in total suspended solids (TSS) of greater than 80%; and�

a reduction in total nutrients (TN + TP) of greater than 45%.�

Future public domain and building Project Applications will address WSUD and the stormwater catchment strategy appropriately adapted.

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

6.6.4 RecommendationsThe project works will be undertaken in conformance with Appendices S, W and X, including:

To avoid impacts to the marine environment from movement of �contaminated groundwater from adjacent areas, it is recommended to avoid/minimise contact with seawater and minimise disruption to the gravel foundations below the caisson structure, whilst the basement retention structures and retaining walls are being constructed.

To manage any potential water quality impacts, water quality monitoring be �considered as described in the Water Quality Monitoring Requirements report at Appendix X.

Water quality control measures that should be implemented include �appropriate excavation methods, installation of turbidity (silt) curtains, erosion and sediment control measures, dewatering and water treatment, routine visual inspections, stormwater management, water quality monitoring, and monitoring of weather and tides.

Water quality monitoring activities required for the bulk excavation and �car park basement activities would be incorporated into a Water Quality Monitoring Plan developed for Stage 1. This will establish a consistent approach to monitoring of all construction activities.

Scope should be included for additional water quality monitoring to be �undertaken during construction operations in response to potential water quality exceedence events when required.

Water quality criteria that can be applied for this project should be based on �recommendations provided in the ANZECC Guidelines.

The above recommendations have been incorporated into the draft Statement of Commitments.

6.7 Waste ManagementA Waste Management Plan (WMP) has been prepared by ARUP and is located at Appendix R. The WMP identifies waste sources during demolition, construction and operation and proposes measures to manage waste in a way that satisfies all legislative requirements.

The project design generally adopts the recommendations of Appendix R. Space has been allocated within the basement levels to accommodate the estimated levels of waste generated by the future Stage 1 development once operational. Separate waste strategies have been developed for the future retail, commercial and residential uses on the site, and will be detailed in future Project Applications for the built form.

As required by the DGRs, the WMP also contains specific details on:

the quantity of non-liquid and liquid waste; �

the quantity, type and specification for all output products;�

the intended end uses for output products and the standard used to assess �those products;

the layout, treatment process and environmental controls of the proposal;�

the management of non-liquid and liquid waste; and�

spoil disposal.�

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

6.8 Air Quality and OdourThe Air Quality Impact Assessment (AQIA) has been prepared by AECOM and is located at Appendix Y. The AQIA identifies the potential construction activities and associated primary pollutants of concern, the nearest sensitive receivers, and assesses the air quality impacts in accordance with the relevant DECCW guidelines and policies.

The dispersion modelling predicts that there will be short-term exceedences of PM10 and NO2 levels as a result of the basement retention system excavations and the bulk excavation emplacement works, with exceedences of the annual total suspended particulate matter (TSP) criterion also predicted at three ground level receptors for the bulk excavation scenario.

The exceedences were primarily predicted at receptors located closest to the site (i.e. those located across Hickson Road and adjacent to the emplacement activities proposed at Headland Park). The exceedences primarily affected commercial properties, which are likely to be serviced by air conditioning. As such, actual effects on people within those buildings would be determined by the locations of the air conditioning intakes. It is noted that the Headland Park activities will be assessed by the Barangaroo Delivery Authority as part of its Headland Park Early Works Project Application proposed to be submitted in June 2010.

The AQIA recommends that a review should be undertaken of potentially affected buildings to determine whether intake valves are located on the sides of buildings closest to the Barangaroo site. If the valves are not located on the western side of the buildings then the emissions from the site are not likely to significantly affect air quality within the buildings.

In the event that the intake valves are located on the sides of buildings closest to the Barangaroo site, the AQIA makes a number of recommendations, which have been incorporated into the ECSMP (see Appendix O), to minimise and mitigate any impacts of the activities on these receptors.

In particular the AQIA recommends a monitoring program be implemented that includes continuous monitoring of PM10 levels, which will allow reactive management of elevated dust concentrations, and monitoring of TSP concentrations using high volume air samplers, which will additionally allow the analysis of heavy metals concentrations to validate the modelling results.

Furthermore, the monitoring program also includes odour monitoring along the boundary of the bulk excavation works and at adjacent sensitive receptor locations, again to validate the modelling results and ensure no adverse effects on neighbouring properties. The proposed monitoring plan has also been incorporated into the ECSMP prepared for the site (see Appendix O).

While no exceedences of the odour criterion of contaminants were predicted to occur, monitoring of these parameters is recommended to verify the modelling results.

The AQIA concludes that if the onsite activities are implemented in accordance with proven and industry standard dust and odour management techniques, there still exists the risk that under certain conditions, exceedences of DECCW criteria may occur for selected pollutants (TSP, PM10 and NO2). With the application of a strict reactive air pollutant monitoring program and the implementation of additional mitigation measures in the event measured pollutants levels exceed their criteria (as set out in the AQIA), it is expected that adverse impacts on surrounding sensitive receptors will not occur.

The project will be undertaken in conformance with Appendices N and Y and accordingly the above recommendations have been incorporated into the draft Statement of Commitments.

6.9 Noise & Vibration

6.9.1 Construction Acoustic Logic Consultancy has undertaken an Excavation and Construction Noise and Vibration Assessment and Noise and Vibration Management Plan for the proposed development (Appendix Z).

To determine the existing background noise levels, noise monitoring was undertaken on 6 June 2007, 14 December 2007, 29 April 2010, 5 May 2010 and 12 May 2010 in the locations shown in Table 8 and Figure 8.

Figure 8 – Sensitive Noise Receivers around the Barangaroo site Source: Acoustic Logic

In summary, the results of the assessment are as follows:

The commercial receivers located on Hickson Road that operate with closed �windows and are air conditioned will not generally exceed the Noise Affected Management Level and therefore will not be adversely affected;

The commercial receivers located at the northern end of King Street Wharf, �and at the “Top Floor Café”, in worst case situations, will exceed the Noise Affected Management noise goals, primarily due to excavator mounted hydraulic hammers and sheet piling operations;

The residential premises near the site including those on the Balmain �Peninsula (with openable windows) will receive noise levels exceeding the Noise Affected Management noise goals;

Activities proposed during 6pm-8pm during the week (Mondays – Fridays) �are anticipated to generate noise levels that will not exceed the existing background levels by more than 5dB(A), and accordingly minimal or no impacts are expected;

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

Between 7am and 8am and 1pm and 5pm on Saturdays, predicted �noise levels are expected to not exceed the City of Sydney’s Category 1 construction hours;

The application of DECCW’s more stringent Industrial Noise Policy noise �emission requirements to the proposed dewatering and groundwater treatment plant demonstrate the noise levels can be suitably managed.

Hydraulic hammering and sheet piping operations have been identified as being the noise sources producing exceedances of the management goals and these activities should be specifically managed in accordance with the Noise and Vibration Management Plan attached as Appendix 2 to Acoustic Logic’s Noise and Vibration Management Plan (Appendix Z).

Mitigation measures identified in the Noise and Vibration Management Plan include:

Selection of alternate appliances or processes;�

Acoustic barriers and buffer zones;�

Silencing devices;�

Material handling;�

Treatment of specific equipment;�

Establishment of site practices;�

Strategic positioning of processes on site;�

Establishment of direct communication with affected parties;�

Management training�

Complaints handling; and �

Monitoring.�

The remaining proposed construction activities will generally comply with DECCW Noise Affected Management Levels of (rating background + 10 dB(A)). However under worst case conditions cumulatively these may cause small minor exceedances of the Noise Affected Management level. These exceedances would be minor and given that some of these processes would be used in place of (much louder) hammering no specific additional management measures are proposed for these processes.

Construction Traffic Noise

The roads most impacted by traffic generated by the proposed construction activities would be Hickson Road and Sussex Street.

Proposed noise mitigation measures include:

Implementation and use of a site based haul route located entirely within the �Project Application Site between the basement excavations passing through the eastern edge of the temporary Passenger Terminal adjacent to its car park/bus handling roadway and to the site of the proposed Headland Park;

The amount of spoil to be trucked off site will be reduced significantly �through reuse and sustainability initiatives associated with the beneficial reuse of material within the Headland Park;

Onsite crushing and screening of concrete for reuse on site thereby �potentially reducing material transported off site;

Commencement of major concrete pours as early as possible so as to �minimise use of public roads during peak hours.

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The Report concludes that adverse noise impacts generated by heavy vehicle movements will be minimal. Notwithstanding this, the site exit for vehicles leaving the site in a southerly direction will be located as far as practicable to the south of the site to minimise vehicle noise impacts.

Vibration

Due to the significant distance separation between the activities and most sensitive structures or occupancies and the nature of the works being undertaken, predictions indicate that the recommended vibration levels will not be exceeded and additional mitigation methods are unlikely to be required.

The only receivers where excessive vibration may be produced are the receivers at the northern end of King Street Wharf. The Report recommends that a “Basements Noise and Vibration Management Plan” be prepared to ensure these structures are protected.

The above recommendation has been incorporated into the draft Statement of Commitments.

6.9.2 OperationalAn Acoustic Report has been prepared by ARUP to identify and discuss acoustic issues relating to the operation of the basement (see Appendix AA). As the proposed development does not seek approval for the uses within the basement areas the operational acoustic impact does not arise at this stage. Acoustic assessments will be undertaken as part of the future Project Applications for the operational aspects of the basement, as relevant.

6.10 Health ImpactsThe proposed scope of works have the potential for health impacts upon nearby residents, workers and the general public which will need to be anticipated and addressed. As a result a Health Impact Assessment has been prepared by AECOM and is located at Appendix BB.

The main potential for human health impacts is considered to be through the inhalation of dust originating from contaminated soil. Dermal contact and oral ingestion of deposited dust also pose a risk of health impacts. The significant exposure groups which may potentially experience health impacts are considered to be workers on site, nearby residents and children staying at the childcare facility at 30 The Bond on Hickson Road.

The Assessment concludes that with the implementation of recommended control measures, it is expected that the risk of exposure to harmful concentration levels of Pollutants of Potential Concern (PoPC) would be acceptable.

To ensure that potential human health impacts on nearby sensitive receptors are minimised, the report recommends that the pollutant management measures (detailed in Appendix BB) such as dust suppression, hoardings, and surface stabilisation amongst others, are implemented through the Environmental, Construction, and Site Management Plan (ECSMP). The ECSMP (see Appendix O) incorporates the pollutant management measures recommended.

The Assessment also recommends that in order to confirm the actual concentrations of PoPC within the site and at selected sensitive receptors beyond the site boundary, a monitoring program should be developed and implemented. The results from the monitoring program should be linked to corrective actions in case of any exceedences of adopted assessment criteria, including the modification of work patterns and procedures and the implementation of additional control measures.

6.11 Climate Change and Sea Level RiseA Climate Change and Sea Level Rise Assessment has been prepared by ARUP and is located at Appendix CC. The Assessment has been prepared in accordance with the NSW Sea Level Rise Policy Statement and NSW Draft Coastal Planning Guideline: Adapting to Sea Level Rise. The NSW Government has adopted a planning benchmark of 0.9m mean sea level rise by 2100.

The Assessment demonstrates that there is a risk that a 0.9m sea level rise could result in inundation of the Barangaroo site by either direct coastal inundation or by a failure of the stormwater system where the discharge point to the Harbour would become submerged.

As a result the Assessment recommends the establishment of a sea wall, or subsequent landward change in the proposed public domain height, at a minimum height of 2.575 AHD. The recommended sea wall height is based on it being:

greater than the current 1 in 100 year event (1.435 AHD) for Sydney �Harbour plus an additional 0.9m to accommodate mean sea level rise (2.335 AHD); and

equal to the current Sydney Harbour Foreshores DCP (1.675 AHD) plus an �additional 0.9m (2.575 AHD).

It is also noted that the height of the wall should be incrementally increased in the future to respond to actual demonstrated sea level changes.

The Assessment makes the following recommendations concerning the management of stormwater:

The stormwater discharge point should be located within the existing �caisson structure seawall or basement perimeter retention system wall (in the case of the Southern Cove) at the highest point possible to allow gravity flow of the site run-off to the Harbour.

The pipeline should be designed to be of sufficient capacity to manage �partial backfilling from inundation during storm surge events which may occur towards 2100.

Overland flow paths should also be identified to manage the stormwater �flows should the discharge point become obstructed which may occur towards 2100 during an extreme storm surge event.

The Assessment also concludes there is a residual risk of inundation impacts on the basement development if mean sea level rise in Sydney Harbour is greater than 0.9m and an extreme storm surge event occurs greater than the current 1 in 100 year event. To mitigate these residual and co-incidental risks, the following measures are recommended:

selecting materials to prevent accelerated degradation of infrastructure �and buildings;

locating key infrastructure at elevated locations closer to Hickson Road �(such as substations);

providing for safe exit routes above storm flood height levels; and�

adopting principles of adaptive management such as the design of future �public domain elements and seawalls is designed so its height may be incrementally increased should future research, change in Government policy or actual events suggest that sea level rise will be greater than current projections.

The project will be undertaken in conformance with Appendix CC and accordingly the above recommendations are reflected in the draft Statement of Commitments.

6.12 Heritage

6.12.1 Non-Indigenous ArchaeologyA Non-Indigenous Archaeological Assessment has been undertaken by Casey and Lowe and is located at Appendix M. The Assessment concludes that there is a moderate to high level of archaeological potential across most of the site. The site contains a mixture of archaeological remains associated with maritime infrastructure, shipbuilding and industrial land uses, in particular:

early maritime infrastructure (1810s-1830s) with associated stores and �reclamation processes, notably Portion 20 associated with Prosper de Mestre and Francois Girard;

Henry Bass’ early shipyard;�

the AGL gasworks (1839-1921) which is highly contaminated;�

mid 19th-century wharfage which is augmented, demolished and upgraded �through time until it became the Grafton wharf which was associated with the nearby bond stores; and

new wharfage in the 1880s involved the raising of street levels (0.60m) to �accommodate larger ships.

The Assessment acknowledges that there is limited opportunity to retain archaeology in situ within Barangaroo Stage 1 and that the archaeological remains will be impacted by the proposed bulk excavation. As a result the report makes the following recommendations:

A program of archaeological investigation should be undertaken and an �excavation director appointed to manage the program.

A Research Design and Management Strategy report needs to be written �to guide this investigation, which is prepared in accordance with applicable Heritage Council guidelines.

Testing of areas of impact within the study area should be carried out to �determine the nature and depth of archaeological remains and to assist the development of an archaeological management strategy.

Based on the archaeological integrity of the remains, a program of �archaeological salvage and recording should be undertaken. Salvage is to include sampling sections of the site, such as:

Recording a number of sections of the later 19th century wharfage, - notably the Grafton wharf.

The maritime infrastructure, stores and reclamation in Portion 20, Block 2.-

If possible the remains of Henry Bass’ early shipyard and - associated reclamation and expansion of the site, but dependent on contamination issues.

The nature of the area’s reclamation fills should be investigated – these - will be present throughout the study area.

Evidence for the early topography and natural landform and how this was - modified through time.

Develop a strategy for recording as much of the gasworks as possible within �the constraints of the contamination to human health and safety.

The archaeological sampling and recording need to be undertaken according �to adoption and implementation of Heritage Branch guidelines and best practice archaeological methodologies. This will then feed into the future interpretation and produce a detailed record of the site.

A repository for the artefacts recovered from the site will need to be provided.�

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

As required by the Barangaroo Concept Plan Statement of Commitments, an Archaeological Research Design and Management Strategy has been prepared by Casey and Lowe and is located at Appendix DD. The Strategy is intended to provide guidance and methodologies for undertaking the archaeological program within the approved development.

6.12.2 Indigenous ArchaeologyAn Aboriginal Cultural Heritage Assessment has been prepared by Comber Consultants and is located at Appendix N.

There are no recorded Aboriginal sites within the Project Application Site. As the site has been developed there is no surface visibility, however, an assessment was undertaken to determine whether any sub-surface Aboriginal archaeological deposits could remain.

The Assessment concludes that it is possible that sub-surface Aboriginal archaeological deposits may remain within the site in the form of stone tools or remnant midden material.

The Assessment recommends that given the proximity of known sites around the Sydney Harbour foreshore, a program of subsurface testing should be undertaken prior to construction of the proposed development within the area where the original shoreline was located as shown in Figure 9. It is noted that testing is not required within the areas of reclaimed land.

Figure 9 – Plan showing the footprint of the proposed basement areas (including the DECCW declared area basement) and the 1822 shoreline Source: Comber Consultant

The Assessment makes the following recommendations which have been incorporated into the draft Statement of Commitments:

A program of Aboriginal archaeological sub-surface testing should be �undertaken prior to the redevelopment of Barangaroo Stage 1. Prior to commencement of the testing, a research design and archaeological management plan should be prepared which clearly sets out the methodology to be followed. This document should also consider issues of contaminated soils, the impact of remediation on the archaeological resource and mitigation measures.

Such a program of sub-surface testing should be undertaken in partnership �with the Metropolitan Local Aboriginal Land Council.

If any Aboriginal “objects” (as defined under the National Parks and �Wildlife Act 1974) are located during the course of the testing program, the Metropolitan Local Aboriginal Land Council should apply for a Care Agreement with DECCW to enable retention of any discovered relics.

Page 63: Environmental Assessment Report Project … Excavation and Basement Car Parking PA1 (MP10_0023) Barangaroo Stage 1 June 2010 10051 Environmental Assessment Report Project Application

55JBA Urban Planning Consultants Pty Ltd 10051

Bulk Excavation and Basement Car Parking (MP10_0023) Project Application | June 2010

The program of sub-surface testing should be coordinated with �Casey & Lowe, the archaeologists undertaking testing in respect of the historical archaeology.

If, during the course of the redevelopment, any previously undetected �Aboriginal “objects”, artefacts or sites are uncovered, work must cease in the vicinity of that object, artefact or site and further advice sought from the archaeologist who undertook the program of sub-surface testing.

Interpretation of the Aboriginal history of the site should be included in the �redevelopment proposals.

As the Assessment recommends that testing be undertaken an Aboriginal Archaeological Management Plan and Research Design report has been prepared by Comber Consultants and is located at Appendix EE. The Assessment provides strategies for managing Aboriginal archaeological heritage within the proposed site and sets out strategies and research design to enable the testing recommended in the Aboriginal Cultural Heritage Assessment to be undertaken.

6.12.3 Interpretation StrategyThe approved Concept Plan’s Statements of Commitment require an Interpretation Strategy to be prepared prior to any works commencing that involve surface disturbance. An Outline Interpretation Plan has therefore been prepared by Tanner Architects and is located at Appendix FF.

The Plan, which was prepared for the entire Barangaroo Stage 1 area:

identifies the themes and messages considered significant to the Stage 1 area;�

develops a conceptual approach to interpretation of the Stage 1 area, using �a variety of means;

proposes locations for specific interpretation to enhance the understanding �of the heritage significance of the Stage 1 area; and

recommends methods and media appropriate to the interpretation of the �Stage 1 area.

Where appropriate interpretation options recommended in the strategy will be implemented through the basement areas. During the excavation works, any archaeological relics or other cultural artefacts identified will, where appropriate, be incorporated into future public displays.

6.13 Geotechnical ImpactsA Geotechnical Report has been prepared by ARUP and is located at Appendix F. The preliminary assessment indicates that the geotechnical conditions on the site are suitable for the proposed development. The Report also provides advice on the engineering methods which could be implemented when developing the detailed construction drawings for the proposed works.

6.14 Acid Sulfate SoilsAn Acid Sulfate Soils Management Plan has been prepared by AECOM and is located at Appendix I. Potential Acid Sulfate Soils (PASS) have been identified to be potentially present at depths ranging from -10.58 – 15.36m AHD across the proposed excavation areas of the Project Application Site.

The ASS Management Plan outlines the strategies for dealing with the PASS. In general the PASS material will be placed into an appropriately bunded treatment area (pads) and treated with a neutralising agent (e.g. lime, or taken off site for disposal at an approved landfill site). The treatment pad design details are presented in the ASS Management Plan.

6.15 Tree RemovalA Tree Health and Assessment Report has been prepared by Jacksons Nature Works and is located at Appendix L. The Report assesses the health and significance of all the trees (124) located on and around the Barangaroo Stage 1 site.

The assessments of the 74 trees proposed to be removed as part of the Project Application were categorised as being:

not represen� tative of remanent vegetation found at Millers Point;

not rare or an endangered species; and�

are able to � be readily purchased at an advanced size.

Therefore the Report supports the proposed tree removal and recommends a Tree Management Plan be prepared with the relevant tree protection measures to minimise any potential impacts on the trees proposed to be retained.

The project will be undertaken in conformance with Appendix L and as such the above recommendations are reflected in the draft Statement of Commitments.

6.16 Fire EngineeringA Fire Engineering review (see Appendix GG) has been prepared by ARUP to inform the basement design. The review also makes the following recommendations regarding fire safety.

The fire safety of the basement will be developed to meet the Performance Requirements of the Building Code of Australia (BCA). This will be achieved either through meeting the Deemed to Satisfy Provisions noted in the BCA; or, where the design of the building falls outside of the prescriptive nature of the Code, through performance based fire engineering design.

As the basement area will house much of the building services plant for the above ground buildings and therefore will be linked, in some form, to all the buildings on site, the consequences and impact of a fire within the basement will need to be considered and a robust fire safety strategy will be required to achieve an appropriate level of life safety and fire and smoke control. The Fire Safety Strategy should address:

Safe � egress provisions for all basement occupants. However, fire engineered solutions may be required to allow extended travel distances in order to address the functional requirements of the site and constraints of the above ground urban landscape.

The individual fire risks associated with loading docks, substations, data �centres, storage areas and fuel stores, whilst maintaining the functional requirements of the spaces.

Require wherever possible the central and coordinated placement of fire �safety measures having regard to the future above ground buildings’ fire systems. This will include:

wat- er storage for fire safety systems;

sprinkler pumps; and-

hydran- t pumps.

The above recommendations are reflected in the draft Statement of Commitments, in recognition of LL’s intent to carry out the project in conformance with Appendix GG. The draft Statements of Commitments have committed LL to the preparation of the Fire Safety Strategy in consultation with the NSW Fire Brigade, building certifiers, building insurers and relevant stakeholders. The commitments also obligate LL to undertake stakeholder consultation early in the design process to provide LL with the opportunity to appropriately resolve all fire safety engineering matters and proposed evacuation strategy(ies).

6.17 BCAMcKenzie Group Consulting has reviewed the documentation for the bulk excavation and basement car parking against the relevant provisions of the BCA (see Appendix HH).

The Report concludes that the proposal will generally comply with the BCA and where there are areas that do not comply with the deemed to satisfy provisions, an alternate solution prepared by a suitable qualified person will be prepared to ensure compliance with the Performance Requirements of the BCA. This will include assessment of the egress provisions for the building to BCA Performance Requirements DP4. Where items for which an alternate solution is prepared relate to Category 2 items under the Environmental Planning & Assessment Regulation 2000, approval will be required by the NSW Fire Brigade as part of the Construction Certificate process.

The above recommendations are reflected in the draft Statement of Commitments, in recognition of LL’s intent to carry out the project in conformance with Appendix HH.

6.18 AccessMorris Goding Accessibility Consulting have undertaken an Access Review of the proposed application (see Appendix II). The Review provides a series of commitments for the detailed design of the car park, including:

Bovis Lend Lease and Morris Goding Accessibility Consulting will examine �key physical elements, to identify physical barriers, and incorporate solutions as a suitable response to disability statutory regulations.

The design will be developed to ensure the principles of the Disability �Discrimination Act (DDA) are upheld.

The car parking design will comply with the requirements of AS2890.6 and �include requirements for accessible paths of travel and seamless integration within the basement car parking under the draft DDA Premises Standards.

The developed design of the basement car park will provide a consistent �accessible environment through detailed design and planning of integrated accessible network of paths of travel to the precinct and associated ferries and public transport. This will include the provision of appropriate continuous accessible paths of travel, circulation areas, signage, lighting, handrails, stairs, ramps, lifts, accessible car parking layout and positioning, accessible pedestrian and transport linkages.

The above recommendations are reflected in the draft Statement of Commitments, in recognition of LL’s intent to carry out the project in conformance with Appendix II.

7.0 Draft Statement of Commitments

7.1 Traffic Management and Accessibility Impacts

Construction works will be undertaken generally in accordance with the Construction Traffic Management Plan prepared by ARUP.

LL make the following commitments regarding construction traffic control:

The site traffic control recommendations for each worksite gate entry or exit �point (including all appropriate signage) should be determined by means of a “Traffic Control Plan” to be prepared by an RTA accredited contractor.

Each site entry and/or exit gate number and the name or other description �of its proposed activity should be clearly signposted for the benefit of all approaching site traffic, in particular emergency services vehicles.

The vehicular traffic movements at each of the site entry or exit gates for �traffic to and from Hickson Road will potentially need to be controlled by a flagman to ensure no potential traffic safety conflicts occur between the site truck traffic and pedestrians on the adjacent footpath.

7.2 Remediation Action PlanThe remediation works will be undertaken to make the site suitable for the proposed uses as envisaged under the approved Concept Plan.

Remediation works will be undertaken in conformance with the Overarching RAP (ERM) and the site specific RAP (AECOM).

A HHERA will be prepared and set Site Specific Target Criteria (SSTC) to detail specific remediation works.

An Environmental Management Plan (EMP) will be prepared prior to commencement of works. The EMP will detail:

surface water and ground water management;�

air quality management; and�

noise and � vibration management;

7.3 Soil and WaterLL make the following commitments regarding soil and water management:

To manag� e any potential water quality impacts, water quality monitoring will undertaken as described in the Water Quality Monitoring Requirements report at Appendix X.

The following water quality control measures will be implemented: �appropriate excavation methods, installation of turbidity (silt) curtains, erosion and sediment control measures, dewatering and water treatment, routine visual inspections, stormwater management, water quality monitoring, and monitoring of weather and tides.

Water quality monitoring activities required for the bulk excavation and �car park basement activities would be incorporated into a Water Quality Monitoring Plan developed for the overall project.

Additional water quality monitoring will be undertaken during construction �operations in response to potential water quality exceedence events when required.

Water q� uality criteria that will be applied for this project will be generally based on recommendations provided in the ANZECC Guidelines.

7.4 Waste ManagementConstruction works will be generally undertaken in accordance with the Waste Management Plan (WMP) prepared by ARUP.

7.5 Air Quality and OdourA monitoring program will be implemented that includes monitoring of PM10 levels, which will allow reactive management of elevated dust concentrations, and monitoring of TSP concentrations using high volume air samplers, which will additionally allow the analysis of heavy metals concentrations to validate the modelling results.

7.6 Noise & VibrationAll construction activities will be managed in accordance with the Noise and Vibration Management Plan prepared by Acoustic Logic.

7.7 Climate Change and Sea Level RiseTo mitigate these residual and co-incidental risks of climate change and sea level rise, LL commits to:

generally selecting materials to prevent accelerated degradation of �infrastructure and buildings;

locating key infrastructure at elevated locations typically closer to Hickson �Road (such as substations);

providing for safe exit routes above storm flood height levels; and�

noting the recommendations set out in ARUP’s Climate Change and �Sea Level Rise Report (Appendix CC) regarding the potential adaptive management of the seawall / public domain elements. Future Project Applications will be designed to ensure the future seawall’s height or public domain elements may be incrementally increased should future research, change in Government policy or actual events suggest that sea level rise will be greater than current projections.

7.8 Heritage

7.8.1 Non-Indigenous ArchaeologyLL make the following commitments in relation to non-indigenous archaeology:

Undertake a program of archaeological investigation with an excavation �director appointed to manage the program.

Testing of areas of impact within the study area should be carried out to �determine the nature and depth of archaeological remains and to assist the development of an archaeological management strategy.

Based on the archaeological integrity of the remains, a program of �archaeological salvage and recording will be required. Salvage would include sampling sections of the site, such as:

Recording a number of sections of the later 19th century wharfage, notably - the Grafton wharf.

The maritime infrastructure, stores and reclamation in Portion 20, Block 2.-

If possible the remains of Henry Bass’ early shipyard and - associated reclamation and expansion of the site, but dependent on contamination issues.

The nature of the area’s reclamation fills should be investigated – these - will be present throughout the study area.

Evidence for the early topography and natural landform and how this was - modified through time.

Develop a strategy for recording as much of the gasworks as possible within �the constraints of the contamination to human health and safety.

The archaeological sampling and recording need to be undertaken �according to Heritage Branch guidelines and best practice archaeological methodologies. This will then feed into the future interpretation and produce a detailed record of the site.

The proponent or the Barangaroo Delivery Authority will need to provide a �repository for the artefacts recovered from the site.

7.8.2 Indigenous ArchaeologyA program of Aboriginal archaeological sub-surface testing will be �undertaken prior to the redevelopment of Barangaroo Stage 1.

The program of sub-surface testing will be undertaken in partnership with �the Metropolitan Local Aboriginal Land Council.

If any Aboriginal “objects” (as defined under the National Parks and �Wildlife Act 1974) are located during the course of the testing program, the Metropolitan Local Aboriginal Land Council should apply for a Care Agreement with the DECCW to enable them to keep the objects.

If, during the course of the redevelopment, any previously undetected �Aboriginal “objects”, artefacts or sites are uncovered, work must cease in the vicinity of that object, artefact or site and further advice sought from the archaeologist who undertook the program of sub-surface testing.

Interpretation of the Aboriginal history of the site will be included in the �redevelopment proposals.

7.8.3 Interpretation StrategyAn Outline Interpretation Plan has been prepared by Tanner Architects and is located at Appendix FF. The Plan, which was prepared for the entire Barangaroo Stage 1 area:

identifies the themes and messages considered significant to the Stage 1 area;�

develops a conceptual approach to interpretation of the Stage 1 area, using �a variety of means;

proposes locations for specific interpretation to enhance the understanding �of the heritage significance of the Stage 1 area; and

recommends methods and media appropriate to the interpretation of the �Stage 1 area.

Where appropriate interpretation options recommended in the strategy will be implemented through the basement areas. During the excavation works any archaeological relics or other cultural artefacts identified will, where appropriate, be incorporated into future public displays.

7.9 Tree RemovalA Tree Management Plan will be prepared with the relevant tree protection measures to minimise any potential impacts on the trees proposed to be retained.

7.10 Fire EngineeringThe fire safety of the basement will be developed to meet the Performance Requirements of the Building Codes Australia. This will be achieved either through meeting the Deemed to Satisfy Provisions noted in the BCA; or, where the design of the building falls outside of the prescriptive nature of the codes, through performance based fire engineering design.

A Fire Safety Strategy will be prepared in consultation with the NSW Fire Brigade, building certifiers, building insurers and relevant stakeholders to address:

Safe egress provisions for all basement occupants. Fire engineered solutions �may be required to allow extended travel distances in order to address the functional requirements of the site and constraints of the above ground urban landscape;

The individual fire risks associated with loading docks, substations, data �centres, storage areas and fuel stores, whilst maintaining the functional requirements of the spaces; and

Require wherever possible the central and coordinated placement of fire �safety measures having regard to the future above ground buildings’ fire systems. This will include:

water storage for fire safety systems; -

sprinkler pumps; and-

hydrant pumps.-

Stakeholder consultation will be undertaken early in the design process to provide Lend Lease with the opportunity to appropriately resolve all fire safety engineering matters and proposed evacuation strategy(ies).

7.11 BCAThe proposed development will comply with the BCA and where there are areas that do not comply with the deemed to satisfy provisions, an alternate solution prepared by a suitable qualified person will be prepared to ensure compliance with the Performance Requirements of the BCA. Where items for which an alternate solution is prepared relate to Category 2 items under the Environmental Planning & Assessment Regulation 2000, approval will be required by the NSW Fire Brigade as part of the Construction Certificate process.

7.12 AccessThe proposed design will utilize the Federal Disability Discrimination Act �(DDA), AS 1428 series, AS2890.6, BCA part D3 to develop appropriate design documentation, to provide adequate access provisions for people with disabilities.

Bovis Lend Lease and Morris Goding Accessibility Consulting will examine �key physical elements, to identify physical barriers, and incorporate solutions as a suitable response to disability statutory regulations.

The design will be developed to ensure the principles of the DDA are �upheld. Under the Disability Discrimination Act (DDA), it is unlawful to discriminate against people with disabilities in the provision of appropriate access, where the approach or access to and within a premises, makes it impossible or unreasonably difficult for people with disabilities to make use of a particular service.

The car parking design will comply with the requirements of AS2890.6 and �include requirements for accessible paths of travel and seamless integration within the basement car parking under the draft DDA Premises Standards.
