Decmil has won a $30 million contract for Rio Tinto's iron ore operations in the Pilbara.
The contract will see it construction major infrastructure on site, such as a heavy vehicle workshop and associated facilities, a first aid building, a security gatehouse, a communications hut, and a radio base station facility, the company says.
Scott Criddle, Decmil's CEO, said "it provides confirmation that at a time when tere is talk of a slowing down in the iron ore sector, Decmil's long standing relationships with major mining companies places us in a very strong position to continue to win significant contracts.
"We anticipate commencing this work in Jan 2013 and to complete it by September 2013."
Earlier this year the contractor won another $30 million contract with Rio for its Marandoo mine, constructing heavy mobile equipment infrastructure and facilities.
