This project involved the construction of foundations for three HV electrical sub stations to power mine infrastructure:

  • Detailed earthworks for all below ground formations for foundations and utilities, including reinstatement and final trim
  • Construction of reinforced concrete foundation pads for all following electrical installation works
  • Construction of reinforced concrete transformer foundations complete with bunded containment compounds
  • Construction of conduit pits and excavate for conduit routes and earth grid installations
  • Installation of surface water drainage


  • Use of mechanical lifting techniques wherever possible, to reduce manual handling (typically with a tele-handler and lifting jib for formwork shutters)
