3.0 Location and siting

3.1 LocationAnglesea Barracks is located at 6-120 Davey Street, Hobart, Tasmania. The site sits south of theCentral Business District (CBD), refer to Figure 1, and inset satellite image, for site locality plan.

Figure 1 Anglesea Barracks locality plan (Satellite image inset)



9AECOM

4.0 Existing installationThe following section provides an overview of the existing electrical installation at Anglesea Barracksimpacted by these scopes of work.

4.1 OverviewAnglesea Barracks is provided with an electrical network matching the following hierarchy:

Existing Substation – Dedicated for the site and has the point of supply. Existing Site Main Switchboard (MSB) – Supplies the site Low Voltage (LV) infrastructure and

includes the site consumer mains. Existing LV Pillars – Provide the electrical LV ring across the site for added resilience to the

network Existing Building Distribution Boards (DB) – Provide local power and isolation for individual

buildings

The figures below are indicative of the existing Main Switchboard configuration and the site reticulationconfiguration.

Figure 2 Existing MSB SLD



10AECOM

Figure 3 Existing site configuration

4.2 Point of supply (LV)The site is understood to have a 500kVA (11kV/415V) pad-mount kiosk type transformer dedicated asa Department of Defence and located on the premises. This transformer provides the LV point ofsupply to Anglesea Barracks, and it is assumed there are no points of LV supplies separate thosespecifically for Anglesea Barracks.

The transformer is existing and operational. It is understood there are no known issues with thesubstation and that there are no known planned works to have this arrangement modified or upgradedin the future.

The scope of works is limited to the LV infrastructure works and no works are anticipated to, orupstream, of the 500kVA transformer. The Transformer details are: ABB, Rating 500kVA, Impedance5%, Dyn11, LV Amps 667A, 3ph, 415V, 50Hz, LV Breaker SACE Tmax 800A (Trip setting unclear).

4.2.1 Site permissible voltage dropThe site arrangements are deemed to the meet the requirements set withing AS/NZS3000:2018Clause 3.6.2, exception 3,

Where the point of supply is the low voltage terminals of a substation located on the premisescontaining the electrical installation, and

dedicated to the installation

As such, the permissible voltage drop is 7% and has been adopted for this project.



11AECOM

4.3 Electrical distribution network4.3.1 Main switchboardThe site main switchboard is a dated board (circa 2008), however appears to be well maintainedwithout signs of damage. The MSB is located externally, mounted on a plinth with bottom entrybottom exit reticulation. It contains:

Main Isolator, 800 (ABB), Generator Isolator, 630A (ABB) – Manual Transfer, Ring Mains Isolators, 630A x 2 (ABB), Utility Meters, EDMI Subclass 0.5 x 2 Building A0010 submains (ABB) MEN Point

Figure 4 Site MSB

The MSB is considered to be suitable for reuse. The breaker ratings as observed are noted to beappropriately sized for the demand without any known issues on site.

The MSB is not proposed to be upgraded on the basis of it condition and capacity are fit for purpose.

4.3.2 Consumer mains and reticulation

Consumer mainsThe site consumer mains from the point of supply to the MSB are direct buried 3 parallel sets of 4 x 1c400mm2 Cu XLPE cables rated with a current carrying capacity of 1,420A/ph (derated to 0.71).Based on a main transformer rating of 500kVA, the consumer mains would allow for the full rating ofthe transformer to be accommodate on the cables. However, the sites total permissible voltage dropof 7% is the limiting factor on the site wide cable reticulation.

Ring mainsThe site LV ring mains from the MSB through to each LV pillar is direct buried 1 sets of 4 x 1c400mm2 Cu XLPE cables rated with a current carrying capacity of 557A). Based on a main RingMain coupler rating of 630A/ph, 3ph at the MSB, the LV ring mains has nil spare allowance in itscurrent carrying capacity. This is an existing site constraint which limits the open point of the LV ringmains between LV pillar #1 and LV pillar #2.



12AECOM

Additionally, the voltage drop on the LV ring mains exceeds the total permissible voltage drop of 7% inits current arrangement. This configuration restricts the open point to be moved to another location.

Life safety servicesFor life safety services, it is required as part of AS/NZSS3000 that the mains and submains are firerated to WS52 (2-hr fire rating) however clause 7.2.2.2.2 exception 1 states in the instances wherethese cables are installed underground need not be fire rated. Generally, all mains and submains,including the ring mains, are buried direct and it is noted to comply with the fire rating requirements forlife safety services.

4.3.3 Utility meteringThe Anglesea Barracks electrical revenue meters are located at the MSB and configured to read theloadings Ring Main 1and Ring Main 2.

Figure 5 EDMI Revenue Meters Figure 6 Typical Metering Configuration

Upgrades of the utility meters or reconfiguration of these existing meters are not anticipated, norproposed.

The existing MSB has a direct supply to Building A0010, however it is unknown where the revenuemeter for this exists (see figure 5). It is likely that the revenue meter is located within the BuildingA0010 distribution board. Should this not exist, a class 0.5s revenue meter will be required forBuilding A0010.

Subsequently, the DoD utility metering is operated and maintained by Ventia. AECOM has confirmedthe following with the Estate Maintenance & Operational Services (EMOS) Manager, Tasmania: The following three meters capture the full site demand;

- PED051800411:

- PED031700046:

- PED021701359:

kWh and KVAr recorded data at 15s intervals for the years 2018-2020 has been made available;

There are no known meters elsewhere and the above captures the total site demand on theAnglesea Barracks 500kVA substation.



13AECOM

4.3.4 Site LV PillarsThere are 7 site LV pillars that form part of the LV ring and provide supplies to localbuildings/equipment. These 7 LV pillars are of varying condition and configurations however typicallyare as follows:

External LV pillar mounted on a plinth,

PCC couplers for Ring IN Ring Out,

Main Isolator, Typically 300A (ABB),

No MLEG provisions,

Local Bus for final subcircuits,

Local heater, lighting and maintenance GPO,

Energy Check Metering

MEN Point

Figure 7 Typical LV Pillar (#2)

All 7 LV pillars are original boards (circa 50 years) with dated circuit protection, labelling and typicallywould be considered for upgrade as part of the MTR project, in line with the MIEE (MIEE Chapter10_Clause 10.2 states gives the realistic useful life of electrical equipment as 50years).

The LV pillars provide submains to distribution boards and final outgoing subcircuits to localequipment. The units within (isolators, protection and auxiliary controls) are dated and would notcomply with current codes, i.e. split chassis for power and lighting, submetering, RCDs protection.

This Project Scope is proposing the replacement of all LV pillars to meet current codes for thefollowing reasons:

1. Meet current codes and practices, including RCD protection and submetering

2. Allow for the staged upgrade of the LV infrastructure.

3. Renew the electrical infrastructure at its end of life.

4. Provide added resilience of the infrastructure through local MLEGs in the absence of an HVRing (MIEE, Chapter 26, Clause 26.5 (b)).

4.3.5 Distribution boards/final connectionsThe replacement or upgrade of DBs and final subcircuits downstream of the LV pillars is outside of thisProject Scope and not addressed. It is anticipated submains and final subcircuits will be impactedwhen transitioning these cables from the existing LV pillars to new. Beyond these works, anyassessments, upgrades or additional supplies are beyond the scope of these works.



14AECOM

Figure 8 Typical LV Pillar configuration

4.3.6 Site LEGA 440 kVA Local Electrical Generator (LEG) is installed adjacent the substation and supplies directlyinto the site MSB, acting as standby generator for the entire site. This generator is located withingarage building A0012 on site and is controlled via manual transfer switch by permitted on-sitepersonnel. It is understood that this LEG is being upgrades as part of a separable portion of worksand the LEG may be out of commission for a period of time. To address this, MLEGs are proposedfor the new LV pillars.

5.0 Assessment for upgrade

5.1 OverviewThis 90% Electrical Development Plan report follows through on previous assessments undertaken at50% schematic design milestone. The proposal within this report for electrical upgrade is in line withagreed Option 3. For background, the previous options discussed through the project phases are asfollows.

1. Option 1: Radial Feed to McGee Building

2. Option 2: Radial Feeds to LV Pillars

3. Option 3: Complete LV Ring Upgrade

It is of note that the above options have been workshopped through with Defence and additionaloptions may be available for further investigation, however not considered within this assessment. Inparticular should Defence consider exploring additional HV incommers and associated infrastructure,those works are not within the scope of this project.

The overview of Option 3 works is as follows:

1. Retain the site substation and associated upstream infrastructure.

2. Maintain and remedial works on the site main switchboard (MSB).

3. Upgrade site electrical LV pillars, including provisions for (MLEGs).

4. Upgrade site electrical LV ring main, including new cabling and containment (pip and pipenetwork).

5. Strategy for staging of works to minimise disruptions and downtime of existing facilities as faras practical.



15AECOM

6. Provisions within the electrical infrastructure for supply to the new McGee Building (A0208)building.

The following sections of the report provide a summary of the 90% Detailed Design developed toaddress the above.

5.2 Electrical demand5.2.1 Background dataExisting metered dataExisting readings of electrical check meters, revenue meters or historical data have been provided toallow for determining an existing site maximum demand.

LV Pillar specific metered data is not available, however to allow for the LV ring to operate at worstcase, the site maximum demand will be deemed to apply at any of the LV pillars for the purposes ofthis exercise.

The recorded peaks have been noted for both summer and winter loads for comparison. Additionally,a batch of peak loads per season have been reviewed to ensure the values can be considered asconsistent and reliable.

In assessing the site electrical maximum demand, the recorded historical data have been deemed totake precedence over other assessments.

Alternative check methodAs an alternative check, an assessment based check has also been undertaken based on equipment,labelling and breaker ratings.

The maximum demand of Anglesea Barracks has been calculated on a combination of assessmentcriteria listed in Table 2.

The Equipment listed below has been sourced from site photos provided of each pillar, whereavailable.

The allowances have been selected from one or multiple of the following:

- Equipment loading (typical ratings), if final equipment is known based on labelling: or,

- Breaker Rating, if final equipment is unknown based on labelling: or,

- AS/NZS3000 equipment allowances, if applicable: or,

- Area based VA/m2 allowances within AS/NZS3000.

5.2.2 Other inputsDiversityIt is anticipated not all buildings will be in use, nor drawing peak demands, simultaneously. As suchan industry standard diversity of 0.7 may be applied to the maximum demand, i.e. the infrastructureconsiders 70% of the site operating simultaneously as a worst case.

Diversity would be applied onto the Alternative assessment method only but not onto the ExistingMetered Data analysis. It is understood the metered data will already be recording site diversifiedloads.

Spare allowancesThe electrical infrastructure currently serves existing historic buildings with the exception of the newMcGee Building (A0208). The site infrastructure is limited by the supply capacity of the 500kVAtransformer. Furthermore, the site is not known for overloading and tripping of breakers and thereforethe site capacity for the existing demand is deemed appropriate.

There are no known other future projects that are required to be accounted for.

In accordance with MIEE, an annual growth of 3% for 15 years has been considered for this MTRproject and applied as follows:

MSB/Transformer – Existing site peak demand +3% per annum projected for 15 years. McGee Building – Assessed Maximum Demand +3% per annum projected for 15 years.

Note: All new pits and pipes runs will be provided with 2 x 100Dia spare capacity (50%).

5.2.3 Site electrical maximum demandThe electrical maximum demand is assessed at 380A, 3ph based on the following:

1. MSB/Transformer – Existing site peak demand +3% per annum projected for 15 years.2. McGee Building – Assessed Maximum Demand +3% per annum projected for 15 years.

For reference, the recorded peak demands for the existing site have observed on Monday morningsaround 9am in August. These align with expectations where staff would be starting the day on a coldwinter morning by initially switching on building heating elements. The Bureau of Meteorologywebsite notes the coldest day on record for Tasmania in the same week.

The alternative assessed method was carried out however discounted as the assessed maximumdemand exceeds the existing site readings significantly. However, a full breakdown of individual LVpillar maximum demands is provided within Appendix C.



17AECOM

5.3 Site voltage dropThe following criteria has been applied to the site reticulation voltage drop:

Figure 9 Designed voltage drop

5.4 LV ring mainsThis project scope, in line with Option 3, includes for the replacement of the entirety of the LV ringmains to alleviate the following existing constraints:

1. The existing current carrying capacity of the 4 x 1c 400mm2 Cu XLPE ring mains, afterderating, will not be adequate for the site maximum demand in the event that the open point ismoved to another location on the network.

2. The existing site voltage drop on the ring mains will not meet the 7% permissible voltage dropin the event that the open point is moved to another location on the network.

As part of this Project, it is proposed that the ring mains be replaced with new in full to comply withAS/NZS3000 and AS/NZS3008. To minimise waste on site, it is further proposed to base the designon cable sizes that match the existing. This allows sections of redundant cables to be retested, and ifdeemed suitable for reuse, repurposed for new sections of the LV ring mains.

The final ring mains configuration will be 3 parallel sets of 4 x 1c 400mm2 Cu XLPE +E throughout.

Should Defence consider exploring additional HV incommers and associated infrastructure, thoseworks are not within the scope of this project and any associated assessments have not beenundertaken.

5.5 Site reticulationAll new cabling will be installed in multiple underground HDPVC conduit (100mm dia) throughout.Conduits will be reticulated and accessible via electrical pits throughout.

The typical pit and conduit arrangement are detailed in the figure below.



18AECOM

Figure 10 Typical pit and pipe configuration

In consideration of site archaeological constraints, trenches will be shared as far as practical tominimise site earth works. The typical trench configuration is indicated below. Services separationwill be in accordance with AS/NZS3000.

Figure 11 Typical trench detail (AS/NZS3000 trench detail)



19AECOM

5.6 LV pillarsSimilar to the LV ring mains, and in line with Option 3, includes for the replacement of each of the LVpillars to provide the following:

1. Rated to the full size of the transformer rating and maximum demand.

2. Allow for submeters to meet the Building Code of Australia (BCA) requirements for energymetering

3. Allow for RCD protection on all circuits to meet the AS/NZS3000 requirements including

5. Allow for a MLEG connection panel to meet the requirements of MIEE. (MIEE, Chapter 26,Clause 26.5 (b) in the absence of an HV Ring and the potential downtime of the LEG).

For consistency and ease of procurement and maintenance, it is proposed to keep each LV pillarsimilar in configuration as far as practical. The proposed schematic has been developed since the50% Schematic Design Report (SDR), and indicates the typical configuration and includes:

Ring In Breaker

Ring Mains Out Breaker

Ring Mains Bus

LV Pillar Isolator

LV Distribution Bus with split chassis

MLEG Connection Panel

Figure 12 Typical pillar configuration

A full schedule of the proposed LV pillar schedule is provided in Appendix D.

5.7 LEGIt is understood that the existing site LEG is planned for upgrade and is outside of this Scope ofWorks.



20AECOM

5.8 Staging of worksThe upgrades of the LV ring mains will have a severe impact to the existing site utilities. To preventsite wide outages, and minimise disruptions to the facilities, a strategy to upgrade the LV ring mainsand LV pillars applies these basic principles:

1. Supply and install new infrastructure.

2. Introduce local generators to pick up loads systematically.

3. Sequentially transfer loads from existing to new LV pillars.

4. Remove redundant LV pillars.

A detailed staging plan for the proposed design is provided in Appendix B.



21AECOM

6.0 Assumptions and qualificationsThe 90% derailed design milestone progression has relied on information made available to AECOM.However, there are assumptions and risks associated with the design based on this relied uponinformation. The following tables provide engineering assumptions input into the design and riskswhere foreseeable. These were reviewed individually by DEEP in the DD01 revision of this report on24 April 2021.

6.1 Assumptions registerTable 3. Assumptions and Qualifications

Item Assumption Rationale Date Response

1 It is assumed all existing building demandsare within or less than their main isolatorratings, or the assessed maximum demands,and these will not be increasing beyond the3% annual growth allowance.The total site electrical maximum demandhas been assessed at 380A/ph, 3ph andincorporates a number of assumptions.

The following strategy has been appliedwithin the assessment to develop the totalsite Maximum Demand (Based off sitephotographs provided for each Pillar):Existing Site

Existing site peak demand +3% per annum

projected for 15 years.

New Buildings

McGee Building: 120 VA/m2 x Area (Table C3

AS/NZS3000) +3% per annum projected for

15 years.

25/05/21 Assumption has beenamended from initialreview comments byDEEP on 24 April 2021.

2 An industry typical site wide diversity of 0.7has not been considered at the MSB and onthe electrical Ring

It is expected that not allbuilding/equipment/loads will be operatingat peak simultaneously and this is reflectedin the historical metered data provided.


3 It is assumed an electrical spare allowance of3% per annum is sufficient an appropriatefor this site.

No further developments beyond the McGeeBuilding are known for the site and 3% hasbeen allowed in accordance with the MIEE.All new pits and pipes have 2 x 100Dia sparecapacity (50%).


4 It is assumed that individual LV pillarsproposed for replacement can be takenoffline and any disruptions to connectedloads will be managed in liaison with the sitecontractor and DoD.

As part of the staging of works, a temporarygenerator is proposed to connect to existingLV pillars to allow for individual Pillars to bedisconnected and removed.These changeover sequences effectivelydisconnect pillars/loads in two parts:

1. individual or multiple LV pillarsnot being upgraded as part of thesequence, are required to gooffline while a temporarygenerator is supplied, connectedand made operational.

2. Individual or multiple LV pillarsbeing upgraded as part of thesequence, are required to gooffline and remain offline until allloads are transferred andcommissioned onto respectivereplacement LV pillars.

13/04/21 Assumption has beenamended from initialreview comments byDEEP on 24 April 2021and discussions withEMOS.

5 It is assumed that, as part of the transfer ofexisting circuits from old LV pillars onto thenew replacement LV pillars, a number ofsubcircuit cables and conduits will require tobe extended or replaced in their entirety.

The suitability of reuse of a subcircuit isheavily dependent on its existing conditionand route to the final equipment from theNew LV Pillar. An exercise has not beenundertaken to assess assets downstream of




22AECOM


This quantity is unknown and will be coveredas a provisional item per LV pillar within thecontract documents.

the LV pillars and therefore this is currentlyunquantifiable.

6 The site voltage drops have been calculatedon the cable routes that are assumed to bepractical. Should these routes need toincrease due to obstructions such asarchaeological or heritage, cable crosssectional areas may need to be reassessed.

The presence of in ground obstructions isunknown at this stage and the presence ofsensitive obstructions may be observed attime of excavations, potentially requiring re-routing of trenches/cables.


7 A site voltage drop allowance of 7% has beenassumed for the electrical infrastructure,including 2.5% for all final sub circuits andsubmains downstream of each LV pillar.

The full details of circuits downstream of LVpillars is unknown and it is expected theexisting installation complies with codes atthe time of installation. Final Subcircuits of2.5% VD have been presumed on each LVpillar in line with typical industry standards.In accordance with AS/NZS3000, Clause3.6.2, Exception 3, 7% has been presumedacceptable as it is expected that thesubstation is dedicated for DoD and islocated on the premises.


8 A derating of 0.179 has been applied for theRing Mains cabling proposed for theseworks.

The value of .179 has been derived fromAS/NZS 3008.1.1, Table 41 for Single Corecables installed within wiring enclosure.


9 The staging of proposed works does notconsider any planned outages or overlapswith any pre-planned periodic maintenancetesting or upgrades.

This information is unavailable at presentand expected to be reviewed in detail withthe Contractor as the constructionprogramme is developed.

13/04/21 Assumption has beenamended from initialreview comments byDEEP on 24 April 2021and discussions withEMOS.

10 The new Pillars 4 and 5 construction detailsare proposed to match LV Pillar 3.

This information is unavailable at present ofthe existing Pillars 4 and 5, however it isassumed these pillars will be similar to theremaining LV pillars on site. Existing LV Pillar3 is the worst case (most circuits) of theknown pillars.


11 Removed Removed 25/05/21 Assumption has beenremoved from initialreview comments byDEEP on 24 April 2021.

12 It is assumed that 6conduits x 100Dia will besufficient as a typical detail from the newPillar to the outgoing pit.

This information of the CSA, conduits andquantities to the outgoing circuits isunavailable at present. It is intended thateach new pillar will be provided with a localoutgoing pit and provided with 6 x 100diaconduits to allow for the amalgamation ofoutgoing circuits.


13 It is assumed that the LV pillars do not needto consider fire and life safety provisions forbuildings and that these are managed at thebuilding Distribution Boards

The infrastructure design does not providefor fire rated ring mains, or a dedicated lifesafety bus/isolator at the pillars on the basisthat the Life safety Bus / isolators are locatedat the building local boards. Fire Rating ofthe ring mains is not required in accordancewith AS/NZS3000, Clause 7.2.2.2.2 whereburied mains, submains and supplies tooutbuilding are exempt.


14 It is assumed that any existing building non-conformances against the BCA/FireEngineering Report (FER) will be addressedas part of the building upgrade works and

Should the electrical buildingloads exceed the assessedelectrical demands, there is arisk that the associatedinfrastructure may requireupgrading beyond currentdesign. This may impact theDBs, MSBs, Substation and anyassociated cabling andcontainment in between.

Possible Major Assumptions listed within theassumptions register werereviewed, accepted as understood.Alternative check for demand; anassessment based checkundertaken based on equipment,labelling and breaker ratings wasundertaken, however historicaldata preferred. Design riskreduced as far as possible withinthe scope of works. EMOS tomanage residual risk via continuingmaintenance, management andoperation of electrical system

2 Removed Removed Removed Removed Removed

3 There is no allowance in theelectrical infrastructure to increasethe existing capacities/demands atexisting individual buildings. There isa risk that upgrades of the existingbuildings may increase the electricalconsumption further impactingoverall site demands.

A higher electrical demand onindividual or multiple buildingsmay require infrastructureupgrades at individual ormultiple points on the network.

Possible Major The electrical infrastructurecurrently serves existing historicbuildings with the exception of thenew McGee Building (A0208).. Thesite infrastructure is limited by thesupply capacity of the 500kVAtransformer. Furthermore, thesite is not known for overloadingand tripping of breakers andtherefore the site capacity for theexisting demand is deemedappropriate.

Design risk reduced as far aspossible within the scope of works.EMOS to manage residual risk viacontinuing maintenance,management and operation ofelectrical system.

4 The suitability of reuse of asubcircuit is heavily dependent on itsexisting condition and route to thefinal equipment from the New LVPillar. An exercise has not beenundertaken to assess assetsdownstream of the LV pillars andtherefore this is currentlyunquantifiable.There is a risk that a number ofsubcircuit cables and conduits willrequire to be extended or replacedin their entirety.

This may add a significant costonto the project constructionbudget and/or impact theprogramme of works.

Possible Moderate This item is to be covered as aprovisional item per LV pillarwithin the contract documents.To be allowed within a projectcontingency

5 There is a risk that the substationsupplying the existing site is notdedicated for DoD.

In this instance, the permissiblevoltage drop on the electricalnetwork will drop from 7%(current design) to 5%. Thiswill have significant impact onthe overall electrical networkdesign.

Unlikely Major Consultation with EMOS anddocumentation review identifysubstation is dedicated to DoD.Residual risk is low enough to closethis risk

6 There is a risk the site Heritageconstraints will significantly impactthe proposed cable routes.

Increases in the cable lengthsfor the electrical ring mains mayrequire additional cablequantities adding to significantproject construction costs

Likely Major To be allowed within a projectcontingency.

7 There is a risk that the FER willrequire changes to the currentelectrical infrastructure proposal.

Any changes may impact onproject construction costs.

Possible Moderate FER and MFPE Compliance reportundertaken for this project. Risk isClosed.

8 There is a risk that the BCA willrequire changes to the currentelectrical infrastructure proposal.
