In addition to the dewatering building and equipment, Zinfra upgraded the existing clarifiers and constructed a centrifuge feed tank, along with new pipework, electrical and control supply to all equipment, and road upgrades.
Zinfra was engaged to construct a 330/33kV substation and carry out associated 330kV line works to connect the new wind farm to TransGrid’s existing 330kV 8E SA Armidale-Dumaresq transmission line. “The greatest highlight of this project was that it was delivered within a 10 month construction timeframe that included over a month of inclement weather experienced during the bulk earthworks phase. This is an exceptional result for a scope of works of this magnitude and a testament to Zinfra’s capabilities,” Zinfra Site Engineer, Luke Perabo, said.
Zinfra’s scope of works for this contract includes the complete construction of 70km of 132kV transmission line connecting the three Wind Farm Collector Substations to the greenfield Terminal Station at Haunted Gully; procurement for all the materials associated with the 132kV transmission line; complete construction of the 500kV/132kV Haunted Gully Terminal Station including all civil, structural and electrical works; and construction of the interface works and cut-over to re-align the existing 500kV transmission line (the main connection between VIC and SA) and connect the Haunted Gully Terminal Station.
