Macmahon Holdings (ASX:MAH) has announced that its wholly owned subsidiary, Decmil, has been awarded an $81 million contract by Rio Tinto (ASX:RIO) for the mobile equipment maintenance workshop expansion at the Brockman 4 mine in Western Australia’s Pilbara region.
The project includes the construction of a new MEM workshop, offices, bulk lube storage, and an oily water system.
Construction is slated to begin in early 2026, with completion expected by April 2027.
