HMAS Cerberus Redevelopment
Upgrading water, electrical, sewerage, stormwater, ICT and gas infrastructure
Upgrade the Water Supply Network
The proposed upgrading of the water supply network include:
- Constructing a new Potable Water Storage. Providing the new potable water storage will involve constructing a new 1.5 day potable water reserve storage tank providing 750 kilo litre of water storage, demolishing the existing potable water storage tank and removing the redundant chlorination plant and providing backflow prevention at the proposed storage tank.
- Remediating the Potable Water Supply Mains. With the exception of the potable water mains constructed in 2004, all the remaining potable water service mains downstream from the existing meter will be replaced. This proposed works include replacing about 7,500 lineal metres of water mains and all valves in those mains.
- Constructing a new Fire-fighting Water Network. The proposed new fire-fighting water service will include constructing two new firewater storage tanks adjacent to western entry gate providing 1,100 kilo litres of water storage. The works also include constructing a new fire ring main network including 1,300 lineal metres of fire mains and pump house to house both the fire-fighting and potable water pumping equipment and connecting all buildings requiring a fire service and the external hydrant coverage to the new system.
Upgrade the Electrical System
The proposed upgrading of the electrical infrastructure upgrading works includes:
- Constructing a new Intake Switching Station. A new Intake Switching Station (ISS) will include new electrical switchgear to accommodate the incoming high voltage (HV) dual feeder from United Energy. The proposed ISS will provide spare capacity to support HV ring main networks to comply with the requirements of Defence’s Manual of Infrastructure – Electrical Engineering. The proposed works include diverting the existing power supply to the new ISS (work by United Energy) and decommissioning and removing the switchgear in the existing ISS. New power factor correction equipment will also be installed.
- Replacing Substations. Seventeen substations, including the ring main units and HV switchgear will be replaced. Four transformers will be upgraded. The cabling directly associated with the replacement or upgrading of the substations will be replaced. The local emergency generator (LEG) servicing the Communications Centre (Building 200) will be replaced.
- Improving Street and Pedestrian Lighting. New street and pedestrian lighting including poles, light fittings, cabling, switchboards and controls to high risk areas where trainees march at night, will be installed.
- Improving Electrical Reticulation. Existing Defence owned overhead HV will be replaced with the underground cable of about 9,750 lineal metres. The low voltage (LV) services to the north of Cook Road will also be replaced with the underground of about 2,700 lineal metres of LV cable. A new dual ring HV network will also be constructed.
Upgrade the Sewerage Network
The proposed upgrading of the sewerage network works includes:
- Replace Sewerage Pumping Stations. Replacement sewer pumping plant will be constructed adjacent to existing sewer pumping stations one and four. Sewer pumping station three will be replaced in a new location north of the proposed RAN School of Survivability and Ship Safety site. Sewer pumping stations one, four, seven and eight will be decommissioned. The sewer rising mains associated with pumping stations one, three and four will be remediated.
- Replace Primary (Trunk) Sewer Mains. The existing deep sewer mains and associated infrastructure to downstream pump stations will be remediated. About 4,000 lineal metres of new sewer main, 150 new manholes will be installed and 50 existing access chambers will be decommissioned and reconstructed to support the remediation of the sewer. Non-compliant stormwater and downpipe connections to the sewer mains will be made good and reconnected to the local stormwater infrastructure.
Upgrade the Stormwater and Drainage Network
The proposed upgrading of the stormwater and drainage network includes:
- Improving Stormwater Outfall Quality. Four bio-retention basins will be constructed on key stormwater mains prior to the outfalls to the adjacent wetlands. One stormwater retention separator unit to capture hydrocarbons will be constructed where the local topography precludes the construction of bio-retention basins.
- Improving Stormwater Trunk Infrastructure. Collapsed areas of the storm water trunk infrastructure will be repaired. About 400 lineal metres of stormwater mains and 526 tormwater pits will be reconstructed and five new stormwater pits will be installed.
Upgrade Information and Communications Technology (ICT) Infrastructure
The proposed upgrading of the ICT infrastructure includes:
- Upgrade the Existing ICT Infrastructure. About 100 non-compliant pits will be upgraded and 80 asbestos pits will be replaced. About 6,500 lineal metres of ICT conduits and 7,500 lineal metres of single mode cable and associated infrastructure will be installed to service the proposed new facilities and to provide capacity for future expansion. Existing distribution nodes in Buildings 53, 190 and 459 will be relocated and upgraded with interconnections to the core nodes in Buildings 200 and 108. Racks, switches and cables will be installed to establish a Defence Engineering Services Network for the monitoring and control of the
new engineering services provided in all new and refurbished buildings. A new Building Management System (BMS) head end unit will be provided in the distribution room of Building 190, and the BMS computer provided in Building 300 and connected to all of the refurbished buildings. All new building metering will be connected to a new reporting system. The 13 existing Security Alarm System panels will be upgraded to Type 1A panels to comply with the current Defence standards.
- Improve the Capacity of the Existing ICT Network. 6,300 lineal metres of existing multi-mode optical fibre cables will be replaced with new single mode fibre cables.
- Rectify ICT Network Compliance. Existing compliance issues with the Defence Voice Network (DVN), Defence Restricted Network (DRN) and Defence Secret Network (DSN) will be rectified. About 50 building lead in conduits will be replaced to meet current standards, 45 ICT cabinets will be replaced with new ICT cabinets to meet current standards, 50 power supplies to ICT cabinets will be rewired and one DVN rack will have earthing installed.
Upgrade the Gas Reticulation System
This project element involves repairing the existing gas reticulation network. The proposed works include replacing the protective PVC sheathing and associated infrastructure where damaged, installing new cathodic protection units to protect the network’s branch lines and upgrading the gas meters. This work element will only be delivered if there savings available through trade gains or program efficiencies.
