GPU POWERNET
- South Morang 330 kV Series Compensator Project
Civil Power was recently awarded a Design & Construct Contract for civil engineering associated with the 330 kV Series Capacitor Banks at South Morang Terminal Station.
This Project is unique as it is the first time this type of facility has been constructed in Australia. CivilPower targeted this project some time ago and accepted the challenge to demonstrate our capacity and expertise in meeting the strict Contract conditions imposed by GPUPowernet.
The Contract value of this Project is approximately $600,000 and work includes design and construct of earthworks, roads, drainage, fire service footings and associated security fencing. The total developed site is approximately 9000 sq. m in area in a difficult low lying flood prone location adjacent GPUPowernet’s existing 500 and 330 kV facility.
Work commenced in late April 1998and was undertaken to a very tight time schedule with design being fast tracked to ensure completion of all primary works in mid July. Electrical erection was completed in December 1998 along with security fencing and final surfacing and associated civil work.
- Richmond Terminal Station 220 kV 5th Transformer Project
Civil Power completed the design of this transformer slab and associated works. The Transformer is located on an abandoned Quarry site which required design of piling to support the transformer slab.
Our involvement includes construction management. The Project is now complete (late March 1999) and the Transformer in service.
ENETECH & ALSTOM
Civil Power was awarded major Civil and Structural Design Contracts by Enetech (earthworks, roads & drainage etc.) and Alstom (Switchyard Structures & Footings) for a new 500 kV Switchyard development at Rowville in Victoria.
This Transformation Project consists of bays 2 & 3 of a future 5 Bay development on a virgin site.
Earthwork and road s design included extensive cut and fill (up to 8 m of cut) into underlying sedimentary rock. Road works design included interface with Stud Road Rowville (to VicRoads requirements). Construction is complete.
Civil design included Fire Service Main and Hydrant system, & Domestic water system and telecom provision and storm water drainage. CivilPower also undertook civil design associated with the High Tech “Sergi” Oil containment system in accordance with EPA requirements.
Structural design consists of development of innovative 500 kV Gantry or Rack Structures utilising tubular steel for tower and girder construction. The unique design was undertaken for full termination of Transmission Lines with loads of 660 kN per bay at a take off height of 23 m. Structural design included ladders and walkways and all associated minor structures (and associated footings) for all plant items in the switchyard.
Further details of this Project and our involvement are available if required.
