CIVIL ENGINEERING SERVICES1. INTRODUCTION

Warren Smith & Partners (WS+P) has been engaged by the New Museum to prepare a services

investigation report of the infrastructure located in close proximity to the MAAS development. The

purpose of the investigation is to ascertain what services will be affected by the proposed development

and to provide a recommendation on what works are required, if any, in terms of diversions and

connections to ensure that there is sufficient access to water with appropriate pressures. WS+P will also

make recommendations on the required infrastructure extensions/amplifications that will need to be

installed in order for the development to be served by sewer, water, and gas

The following tasks were undertaken in relation to gathering information for the purposes of this

investigation:-

· Receipt and checking of the proposed development plan with the existing services drawings;

· A 'Dial Before You Dig' services search, and;

· Report providing recommendation on the works required.

The following upgrades have been recommended to facilitate the proposed development:-

· Amplification of the existing DN150 watermain in Phillip Street to DN200 between the front of the

property and Church Street;

· Deviation of the existing DN225 sewer mains within the development site, and;

· Deviation of the existing DN150 sewer mains within the development site.

1.1 PROPOSED DEVELOPMENT

The proposed development will see the relocation of MAAS, including all museum pieces, from its

location in Ultimo to Parramatta. The proposed site is bound by Wilde Avenue to the east, Phillip St

to the south and the Parramatta River to the north. It is located approximately 500m north of the

Parramatta CBD. Currently, the site is used as a multi-storey carpark with small commercial

properties facing Phillip St.

Please refer to Figure 1 for an aerial view of the development site area.

2. DATA COLLECTION

2.1 SYDNEY WATER HYDRA DATABASE DRAWINGS

WS+P has obtained Sydney Water's Hydra database to assess the available water and sewer

infrastructure in close proximity to the development site.

Please find attached in Schedule 2, the following drawing:-

· Sydney Water Hydra plan at Scale 1 in 1500 which shows the development site on the

northwest corner of Phillip St and Wilder Ave.

The database has shown that the development site has frontage to two (2) Sydney Water water

assets on the southern side of the development site along Phillip St:-

· A DN900mm trunk water main, and;

· A DN150mm water main.

The following Sydney Water water asset is also located on the western side of the development

site along Church St:-

· A DN375 water main

The following Sydney Water sewer assets have also been identified within the development site:-

· A DN525 main which reticulates across the development site parallel to the Parramatta River;

· Two (2) DN225 mains which reticulate in a north south direction across the development site;

· Two (2) DN150 mains which reticulate east across the development site, and;

· A DN500 main which runs under the bridge crossing in Parramatta River.

Please refer to Figure 2 for details.

2.2 JEMENA GAS DIAGRAM

The Jemena diagram received illustrates that there are no network mains traversing the site. The

following is a list of gas networks which run along Phillip St as illustrated in Figure 3.

Please find attached in Schedule 3, the following drawing:-

· Jemena Gas Diagram plan at Scale 1 in 2000.

The database has shown that the development site has frontage to two (2) Jemena assets along

Phillip St:-

· A DN150mm high pressure 1050 kPa secondary main that runs along Phillip St and crosses

to the opposite side of Parramatta River, and;

· A DN110mm low pressure 7 kPa nylon network main.

Please refer to Figure 3 for details.

3.1.2 SYDNEY WATER SEWER MAINS

Multiple sewer mains have been noted within the development site. As per Sydney

Water's previous correspondence with AECOM, connections to the DN525 main can be

made through extensions to existing manholes. However, the DN525 main may require

amplification depending on when developments related to the wider Parramatta CBD

area will be occurring. These developments include the relocation of the DN500 main

crossing Parramatta River which will impact future DN525 capacity.

In order to facilitate the proposed museum footprint, the DN225 and DN150 sewer mains

will need to be deviated. Option 1 to deviate the DN225 sewer main involves intercepting

the main and deviating it north to connect into the DN525. Option 2 to deviate the DN225

sewer main involves intercepting the main, deviating it south and reticulating it along

Phillip St before connecting into the DN450 main located in Wilde Ave. The DN150 sewer

main is to be intercepted and deviated south to connect into the DN225 sewer deviation

along Phillip St. The DN150 which runs through Oyster Lane is to be removed and a new

connection to the lots established from the proposed deviation is to be made through

Phillip St and Wilde Ave.

Please refer to Figure 5 below for details.

4. COST ESTIMATES

4.1 WATERMAIN

The existing DN150 watermain along Phillip Street, from the front of the proposed new building to

Church Street, shall be amplified to a DN200 watermain. Please refer to Table 1 below for a cost

estimate of the proposed watermain.

Table 1: Watermain Amplification Cost Estimate

Item Quantity Unit Rate Total

Amplification of existing DN150 to DN200 170 m j $1,500 r$255,000

4.2 SEWERMAIN

It is proposed that the existing DN225 and DN150 sewers within the development site be deviated

in order to facilitate the new building footprint. Please refer to Figure 5 in Section 3.1.2 for the

proposed sewer main deviations.

4.2.1 EXISTING DN225 DEVIATION

Option 1 involves intercepting and deviating the existing DN225 sewer main north for

approximately 64m and connecting into the existing DN525 sewer main running along the

north of the property.

Option 2 involves intercepting and deviating the existing DN225 sewer main south to

Philip Street, reticulating it east and connecting into the existing DN450 sewer main in

Wilde Avenue. This sewer main deviation option is approximately 272m in total.

The total briefed floor area for this concept is greater than the

current space of the Powerhouse Museum.

Circulation in this option has been increased, as the main entrance and arrivals hall has been pushed to the east of Willow Grove, separating it further from the museum spaces on the west of the site. The entire built form has moved forward towards the river to accommodate the retention of Willow Grove and St. George's Terrace, decreasing the river bank area available for public space and access.
