1.0 Purpose and Description of the Project

1.1 Introduction

Waste management procedures and processes are aimed at ensuring legal compliance, adoption of the waste hierarchy (reduce, reuse, recycle), and best practice measures to eliminate and control waste production on site.

This Demolition and Waste Management Plan (D&WMP) has been prepared in support of the full planning application for the mixed use redevelopment of land known as plots 5 and 6 located and accessed from Acklam Road, London W10 and to set the standards for site waste management going forward. This document sets out the forecast volumes and expected nature of all waste generated by the project during the construction phase, who is responsible for the monitoring and management of waste created, the measures taken to segregate waste appropriately and the methods of monitoring all waste. This D&WMP has been developed with reference to the requirements of BREEAM and the former Site Waste Management Plan Regulations 2008 (revoked in December 2013) and responds to RBKC’s Local Plan policies CE1 (Climate Change) and CE3 (Waste). This plan will develop throughout the various stages of the project and will therefore be treated as ‘live’ and updated accordingly to reflect the most current position of the project. The plan will be developed and implemented in accordance with the following model.

1.2 Project Details

Project Name Plots 5&6 Acklam Road

Project Address Plots 5&6 Acklam Road, London W10

Project Use Classes Residential & Community Space

Site Works Start Date Q4 2020

Site Works Completion Date Q1/Q2 2022

Project Cost (Estimated) £10M

1.3 Site Context

The site is located in Acklam Road, within walking distance to Westbourne Park underground station.

Opposite the site is Al Manaar Muslim Cultural Heritage Centre (to the north-east), while to the south-west there is a four storey residential building forming part of Swinbrook Estate. Al Manaar is a valued local community organisation and an active prayer site. It has ongoing community events and attracts constant usage throughout the year, generating high level of vehicular and pedestrian movement. To the south is the elevated dual carriageway section of the A40 (known as the Westway), at a height of around 8 metres above local ground level. Under the Westway there is a minibus storage area that utilises Acklam Road for access.


5

Directly beyond this, there is a railway section used by the Circle and Hammersmith & City lines of the London Underground, with Westbourne Park station around 100-200 metres to the south-east of the site. To the North, along Acklam Road, is Barley Shotts Business Park with associated parking, hardscape surfacing and street tree planting. To the north-east of the site (beyond Al Manaar Centre) there are several railway lines leading into and out of London Paddington station, serving Great Western Railway, Heathrow Connect and Heathrow Express services. Crossrail, or the Elizabeth line, will also utilise this section of railway once opened.

The majority of the site is currently a temporary wildflower meadow however this is currently unused. An electrical substation is located in the south east corner of the site. This live substation comprises a masonry structure with concrete flat roof. The western side of the site is divided by a chain link fence and contains a large spoil heap of mixed material, previous builders waste material and accumulated rubbish and debris. This disused portion of the site has become overgrown.

1.4 Description of the Development Works

The site redevelopment will be providing residential accommodation on the upper floors, alongside non-residential uses on the ground floor.

The residential dwellings will comprise 32 mixed tenure with one shared tenure blind entrance located on levels 01 to 07. Approximately 810 sqm of D1 flexible community use space will be provided at the ground level.

It is currently envisaged that the building structure is to comprise a reinforced concrete frame supported on an arrangement of capped reinforced concrete piles. External envelopes are to be predominantly masonry with an SFS inner wall. The community area at ground and part level 01 will be provided with storey height glazed panels. Each demise will be divided by twin-wall plasterboard partitioning with further plasterboard partitioning forming the internal apartment spaces.

Internal fit out will comprise typical residential finishes.

1.5 Estimated Site Works Programme

Site Clearance works are expected to commence in Aug/Sep 2020 followed by construction in Oct/Nov 2020. The decommissioning and subsequent demolition of the existing substation is anticipated in Q3 2021. Completion of the project is anticipated Q1/Q2 2022.

2.0 Responsibilities

The Client is responsible for ensuring that a Demolition and Waste Management Plan is prepared and issued for each element and stage of the project.

The Principal Contractor is responsible for the implementation of the Demolition and Waste Management Plan on site from commencement of the project and may also undertake the role of Site Waste Champion (see below). The Project Principal Contractor is responsible for the recording and reviewing of waste returns.

The Contract Administrator and Principal Contractor are responsible for the determining and monitoring of waste management performance targets.

As a part of the Principal Contractor duties the Site Waste Champion is responsible for promoting the awareness of the D&WMP amongst the workforce, monitoring and reporting on waste generation on site, monitoring and enforcing waste separation on site, monitoring the effectiveness of the D&WMP and encouraging suggestions for better waste management on site.

The responsible persons for this site will be identified once the Principal Contractor has been appointed for this project and the main construction works. This document will be updated and the details of the relevant parties displayed on site.

3.0 Waste Identification

3.1 Waste Code Categorisation

The on-site works, consisting of demolition of existing structures and construction of new replacement structures, will typically generate large volumes of waste. It is the responsibility of the developer, designers and contractors to ensure that waste generated on site is reduced as far as possible.

Identifying the anticipated waste material volumes and components is essential to developing a focused strategy for managing the generation and subsequent processing of construction and demolition waste. For this site, the following waste materials have been identified as being likely to be encountered or generated, the following tables includes the European Waste Codes (EWC) for each waste type.

The stage 3 design GA’s and elevations have been used to assess the approximate waste volumes for this size and type of project. Where possible, volumes of materials have been approximated and typical waste factors applied.

3.2 Nature & Volumes of Waste

3.2.1 Decommissioning & Demolition

The site is currently occupied by communal gardens, an electrical sub-station and a small group of trees and shrubs. As such there is little to decommission and demolish. The majority of the demolition waste arising will be from the substation. It is likely that as this is currently live it will be retained until the new substation is commissioned some time into the construction of the new building. The following table provides an assessment of the potential waste arising from demolition and a site clearance works.

3.2.2 Ground Conditions

A number of investigation reports have been prepared for previous development proposals on the site and these reports have been made available to the team. Logs within these reports suggest made ground up to 2.5m deep over from London Clays. Localised contamination was encountered (asbestos and hydrocarbons) which will require removal. Some excavation work was undertaken on the site circa. 2012, however the nature of this work is not yet known. It is possible that excavations were related to the basement plantroom within the adjacent property.

The materials listed above are the expected waste categories for the proposed scheme. following the receipt of further information on the existing structures and-or an updated design for the scheme then the table above will be updated as applicable.

4.0 Waste Handling & Management

4.1 Methods of Reducing Waste

The Principal Contractor will be required to assess all waste materials on site will be assessed for potential re-use, recycling, reduction in volume and finally disposal, disposal being the final and least desirable option.

When procuring materials for site the Principal Contractor will be required where possible to reduce the number of deliveries, waste wrapping and packaging for materials. All material purchases will be scheduled and ordered accurately to ensure there is no excess of materials e.g. correct length of handrails ordered to match the corresponding location on site, materials used where intended.

Material delivery timings will also be carefully scheduled to be in a ‘just in time’ manner to prevent materials from spoiling through long storage periods e.g. plasterboard being damaged through misuse or windows being damaged on site and requiring replacements.

All wastes generated from the development will be assessed for their potential to be recycled or re-used within the project where suitable. All wastes on site must be reclaimed, recycled or re-used on site and will include measures such as re-using large offcuts of wood as noggins or packers, crushed concrete for road-hardstanding sub-base.

The following measures will be taken to encourage waste reduction on site:

• Re-use of offcuts and discarded materials through awareness e.g. offcuts of sufficient length being used as noggins and packers

• Re-use of inert fill for landscaping to prevent export of fill from site • Segregation of waste streams for re-use and recycling on site to prevent general waste skips

being used to dispose of materials which could otherwise be repurposed • Returning suitable equipment to manufacturers for reconditioning and re-use instead of

disposal • Use of specialist handlers for specialist materials such as scrap metalwork • Topsoil stripped from site will be reused in landscaping works

Where possible all waste on site will be re-used and recycled however where this is not possible the Principal Contractor will liaise with the Clients Administrator and determine whether the waste could be utilised on another site and will enquire as to the feasibility of transferring this to another site.


11

5.0 Waste Segregation

Waste materials on site will be separated into the identified waste streams in section 3.0 with any additional material waste streams included as they become applicable. On site, a waste management area will be established within the site compound where the identified waste streams will be separated into to enable the re-use and recycling of suitable materials.

Designated waste segregation area

The waste management area will be secured using demountable mesh fencing or similar to prevent fly-tipping and will be located on a suitable area of hardstanding, materials arising from demolition can be used to create an area if necessary. Within the waste management area there will be 6-8 skips subject to the stage of the project. Where the waste streams are split into the following groups.

Mixed Packaging EWC 15-01-01-02-04-06

This stream combines EWC 15-01-01-02-04-06 which includes general paper, card packaging, plastic, metallic and mixed packaging. These items will consist of all general packaging items to be disposed of to ensure a tidy site and consequently reducing the risk of hazards generated by discarded packaging. This stream will require a single skip and will not include large or bulky waste. All items should be broken down by hand into manageable pieces.

Packaging Containing Residue of Dangerous Substances EWC 15-01-10*

This stream covers EWC 15-01-10* such as aerosol or paint cans, which still contain some residues and so, cannot be included within EWC 15-01-04. This stream will not require a full skip but will have a secure storage area within the waste management area.


12

Concrete EWC 17-01-01

Consisting of all concrete waste which cannot be re-used on site for hardstanding. Where possible this stream will be re-used on alternative sites, due to the size of materials generated in this waste stream, such as concrete blocks and floor tiles etc., a full skip will be required within the waste management area.

Bricks EWC 17-01-02

This waste stream will consist of brick-blockwork generated on site which cannot be re-used on site or, having been suitably packaged, transferred to an alternative site. Due to the weight and size of waste generated in this stream, a full skip will be required.

Tiles & Ceramics EWC 17-01-03

Consists of all tiles and ceramics including roof tiles, floor tiles and additional ceramic items on site. The size of these items will not necessitate a full skip on site but will require a separate storage area to ensure items remain undamaged for future use.

Timber EWC 17-02-01

All timber waste generated on site falls into this waste stream but it does not include M.D.F or chipboard due to the fact these materials already contain glue and break down to dust. All re-usable items will be kept and used on site within the construction works. All items that cannot be re-used will be recycled. This waste stream will not require a skip but will need a suitable storage area within the waste management area to prevent spoiling of potentially re-usable items.

Glass EWC 17-02-02

All glass waste generated on site falls into this stream such as windows or screens. Due to the nature of the waste a separate waste storage area will be required for health and safety, however there will not be a skip required on site.

Mixed Metals EWC 17-04-07

All forms of mixed metal generated on site will fall into this stream, due to the size and weight a full skip will be required for this waste stream.

Soil and stones containing hazardous substances EWC 17-05-03*

Where suspected contaminated or hazardous material or ground is encountered, the Principal Contractor is responsible for commissioning testing on samples to classify the extent and nature of these substances. This shall be undertaken by an NAMAS / UKAS accredited testing facility. The hazardous waste will be carefully segregated and transferred to an appropriate waste handling facility by a registered carrier.

Soil and Stone EWC 17-05-04

This waste stream consists of the remaining inert fill once all landscaping works have been completed. Where possible all materials will be re-used on site or at an alternative site if feasible. This waste stream will require a skip on site.


13

Insulation EWC 17-04-06

This waste stream covers the materials generated from the insulation of the existing building on site or any waste generated from installing new insulation. This waste stream will require a skip on site.

Plasterboard EWC 17-08-02

All plasterboard based materials are included in this waste stream, and will arise from the demolition and from the new construction works. These materials can be broken down in size and a separate dedicated skip will be provided for this waste stream.

Mixed Construction & Demolition Waste EWC 17-09-04

This waste stream consists of the remaining construction and demolition waste not covered within the other waste streams. This waste stream will require a skip on site, where possible all materials will be recycled or re-used.

Canteen Waste EWC 20-01-08

All waste generated by the on-site welfare and accommodation will be captured in this waste stream, it is not expected that a skip will be required for this stream although a separate storage area will be required.

6.0 Training

The Principal Contractor should ensure that all parties working on site are adequately trained in management of the waste they produce and dispose of. Primary training of subcontractors should be undertaken by the Principal Contractor, with subsequent training of all subcontractor staff undertaken by the subcontractors themselves. Everyone on site should receive relevant training which should include:

• The D&WMP • Roles and responsibilities • Waste procedures on site • Hazardous waste • Duty of care - responsibilities • Materials storage

The following types of training are being recommended, depending on the roles and responsibilities of those receiving training:

• Induction • Tool box talks • Workshops

The Principal Contractor should maintain a training log of all those receiving training in relation to this D&WMP. A copy of the training log should be retained on site, and preferably also within the D&WMP document - tool. A sample training log is given below.


14

Name Company Date Who trained by Type of training Date next training due

7.0 Communication

The D&WMP is an active management tool that should be implemented by all employees working on site. It is therefore very important that the requirements of the D&WMP, and the responsibilities of all parties to meet the D&WMP requirements are communicated adequately to all site staff. Possibly means of communicating the D&WMP plan requirements include:

• Inductions • Meetings • Posters • Feedback from staff

8.0 Measuring & Monitoring

It is the responsibility of the Principal Contractor to ensure all waste transferred off site has the legislatively required paperwork is completed, filed and registered correctly. The Principal Contractor is also responsible for ensuring that all documentation has been reviewed and verified to comply with regulatory guidelines. If applicable, the Principal Contractor will register the site as a Hazardous Waste Producer.

All waste transferred or disposed of from site will be recorded via Waste Transfer Notes, which will be completed by relevant individuals in accordance with the document guidelines. These notes will be stored for a minimum of 2 years. All waste transfer notes must include the following information, which is to be checked by the Principal Contractor, and comply with the following:

• Name of person(s) removing waste from site; • Waste Carrier Registration Number – All individuals involved within the transport of waste are

required to register as waste carriers; • All carriers are to hold a valid Waste Management Licence which authorises the carrier to

handle the relevant waste; • All carriers must be registered with the Environment Agency’s public register and a check must

be carried out to confirm the carrier is present on the register; • A brief written description of the waste and confirmation of where the waste is to be taken; • Confirmation that the waste disposal destination is authorised to receive the waste. The

operator of the disposal site is required to hold a relevant permit for the disposal of the waste issued under the Environmental Permitting (England and Wales) Regulations 2016 or has registered as exempt.


15

The waste transfer notes and any accompanying checks or information must be retained for a minimum of 2 years. The Principal Contractor is responsible for ensuring that the site waste segregation systems are being adhered to and to review the Site Waste Management Audit document at least every 6 months if not less. This review is to ensure that the processes within this document reflect the processes on site and to identify changes within the waste streams. The review will encompass:

• Review the relevant waste streams and process on-site; • Make a record of the volumes and proportions of waste disposed of from site and breakdown

the waste into at least the following categories:

o Materials re-used o Materials recycled o Sent for another form of recovery o Sent to landfill o Other forms of disposal

These categories will also show whether the disposal method was on site or off site.

It is the responsibility of the Principal Contractor to ensure that the on-site skips are filled to an appropriate level and to organise the removal of skips on site when full and replacements in a timely manner. The Principal Contractor will also be responsible for ensuring that the waste management area is kept organised and clear.

The Principal Contractor will also record the number of skips and volume of waste leaving site and ensure the breakdown of waste is recorded as above. The Principal Contractor will be responsible for comparing the monthly returns with the volumes of waste and is also responsible for monitoring the effectiveness of the Demolition and Waste Management Plan.

Where efficiencies or deficiencies are identified on site or within the waste management process then it will be the Principal Contractor’s responsibility to implement and effect the required changes. Should a Site Waste Champion be appointed then they shall be responsible for raising awareness of any changes and encouraging adoption of the new processes.

The construction waste management audit review will be presented and discussed on site at monthly progress meetings. The monthly waste volumes and progress compared to the agreed target will be displayed on site notice boards.

The information relayed in the monthly report will be recorded and included in a project completion report. This final review will capture the following information:

• Confirmation the plan has been updated in accordance with the works carried out on site • Details and justification for any variance from the stated plan • A comparison of the actual generated waste volumes against the estimated waste volumes • Any variances between the planned and actual waste volumes generated are to be explained • An estimate of any cost savings generated by the measures set out in within the plan

9.0 Completion Review


16

Demolition and Waste Management Plans are intended to provide both better clarity on construction waste management, and to identify lessons learned that can be applied to future projects by the client or contractor. Therefore it is important to undertake a completion review to:

• Review how successful you believe the implementation of the D&WMP was: • Provide a comparison of the estimated quantities of each waste type against the actual

quantities; • Explain any deviation from the original plan • Estimate of cost savings achieved; • Action planned for next project.

This section should be completed by the Principal Contractor within 3 months of the work being completed on this project (i.e. project finish). The completed D&WMP should be retained by the Principal Contractor for 2 years following completion of the project. All associated documents, including Waste Transfer Notes and Hazardous Waste Consignment Notes should be retained.
