The Alcoa McCoy workshops were a brand new facility located closer to the open cut mine face including an 8xbay heavy vehicle workshop with integrated stores and administration offices, 6xbay light vehicle workshop, 2xbay heavy vehicle refuelling facility and light vehicle refuelling facility.

The heavy vehicle workshops included a lubricant tank farm comprising seven grades of lubricant plus coolant and waste oil reticulated to five hose stations throughout the workshop.

The number of hose reels combining grease, compressed air and water for the project totals 101.

The mine is located above the Perth artesian water supply and subject to strict environmental regulations. Double wall tanks with a secondary contained turret and innovative submersible positive displacement pumps were incorporated into the design along with double wall stainless steel piping.
