The contract includes design and construction of a heavy and light vehicle workshop, washdown facilities, a boilermaker workshop, tyre change area and lube farm.

It also includes power, water and wastewater treatment services and administration buildings, including Go-Line facilities and a gatehouse.

The company said its engineering and infrastructure division would undertake the work in three stages, with a handover of the Go-Line administrative buildings by the second quarter.

The gatehouse will follow mid-year, with all other buildings complete by early 2015.

The facility is being built to service a 142-strong fleet and will house around 250 staff.

It is located close to the 2000-dwelling accommodation camp and 10km from the mine’s process plant.

“Because the mine is situated in such a remote region – about 100km from the nearest town – it’s imperative that provisions for the maintenance of vehicles and the administration and care of staff is readily available onsite,” Brookfield WA regional managing director Chris Palandri said.

“The fleet service and repair facilities will ensure efficient transport of product and personnel across the mine, while the administration buildings will include training rooms, medical services and storage, to assist staff to safely complete their work.”

Palandri said the work was Brookfield’s second engineering and infrastructure contract at Roy Hill, following completion late last year of the $200 million accommodation village.

The village is home to more than 1000 staff, with work ramping up on a number of mine assets and services.

“Roy Hill is focused to export its first ore in September 2015, so it’s all hands on deck from our team to complete all of our contracted work by early next year in preparation for that milestone,” he said.

“The feedback about the accommodation village has been excellent – the workers are saying that the rooms are comfortable, private and appropriate for the climate and they are making the most of the top-class recreational facilities – including pools, a gymnasium and BBQ areas.”

Brookfield says it has a $9.4 billion global workbook across 50 projects.
