The contract is for the design and construction of three temporary accommodation camps for construction workers on the Carmichael Rail Network project.

Lucas Dow, CEO of Adani Mining, said that the contract, which is worth more than A$40 million (US$27.6 million), was another win for regional Queensland.

"This contract means more jobs and economic activity for Rockhampton and regional Queensland," he said. "The Decmil team will move into our Rockhampton office along with Martinus, our track laying contractor.

"This announcement brings the total value of contracts awarded for the Carmichael project to date to more than A$500 million.

"The operations of the rail camps will be based in Collinsville, earthworks and civil works are coming from Townsville and Rockhampton, fuel supply is from Townsville, telecommunications is from Mackay, and many other regional businesses across regional Queensland are also getting involved."

Decmil will design and build three 400-bed temporary accommodation camps along the Carmichael Rail Network corridor. Dow commented: "Our rail construction crews will live in these camps while they build our 200km-long railway line that will link the Carmichael mine with the existing rail network.

"The camps will be designed to maximise our teams' wellbeing with air-conditioned rooms, dining messes, gyms and recreation areas. They will also comply with the high standards of environmental regulation that have been set for our project."

Decmil has also been awarded a A$1.4 million early contractor services (ECS) contract to scope the bulk earthworks required along the primary freight rail alignment. Should the ECS be successfully completed, it is anticipated that Decmil will enter into a contract for the construction works.
