Project Overview

The BHP South Flank project is part of a wider initiative to increase the mining, processing and out-load capacity of the existing BHP Mining Area C (MAC) Iron Ore mining hub in the Pilbara region of Western Australia.

Westforce was engaged to deliver critical electrical infrastructure works that would provide reliable power distribution across the expanded operations. This included the construction of major high-voltage switchyards and multiple substations designed to support the increased operational demands of one of Australia’s largest iron ore mining operations. The project required precise coordination with BHP’s operational requirements and strict adherence to mining industry safety and quality standards in a remote location.

Westforce successfully completed work on the central power terminal, a 132kV switchyard, MAC 132/33kV switchyard, and 12 smaller outline substations.
Works included:

  • Concrete works
  • Civil works
  • Bulk excavation works
  • Stripping and grubbing of existing access tracks and creation of new access tracks
  • Construction of switchyard pad including laying of fill material 600mm thick
  • Construction of gantry foundations
  • Construction of relay room building foundations
  • Roadworks, including kerbing, prime seal and asphalt
  • Switchyard surfacing
  • Trenching for electrical conduits and earth grid
  • Construction of transformer bunds
  • Installation of 3m high palisade fencing including gates

Concrete: 1,300m³ ~
Reinforcement: 120T ~
Trenching: 2,000m ~
Bulk Earthworks: 15,000m³ ~
Fencing: 100m ~
