These areas included the Boilermaker Workshop, HV/ LV Workshop, HV and LV Wash-down Facility, Tyre Change Facilities, Bulk Lube Farm, Go-line Buildings, Administration Buildings and other smaller stores and facilities.

Backfill of trenches must be to specifications, particularly giving due consideration to trenches under roads. This includes all required ducting for all services (electrical, communications, fuel, water, drainage, etc.).
  • Construction of all concrete foundations, anchors, footings and pads.
  • Concrete plinths and footings for electrical switchboards, distribution boards and lighting poles.
