Civmec was awarded a civil and earthworks contract from BHP for the first stage of its port debottlenecking project at Port Hedland.
The scope of work includes dewatering, piling, ground improvement, associated earthworks, concrete foundations, new roads, high voltage poles and underground power works.
The company also won a contract for the expansion of Roy Hill's WHIMS plant.
The scope of work includes greenfield installation and pre-commissioning of pre-assembled modules, piping, electrical and tie in works.
Rio Tinto awarded Civmec a three-year contract to supply refractory trades and other associated disciplines for maintenance, rebuild, and reduction cell reconstruction works on carbon bake furnaces at Boyne Island Smelters in Gladstone.
"We are delighted to secure these project wins with three of our long-term tier one customers," Civmec CEO Patrick Tallon said.
"With the BHP PDP1 project located in the Port Hedland region, it provides an ideal opportunity for Civmec's newly opened regional branch to support the project, validating Civmec's recently announced plans to invest in a purpose-built facility in Port Hedland."
