Rio Tinto has awarded OTOC the accommodation contract for its Brockman 4 operations.
According to OTOC, the $32 million contract will see it install the accommodation units at the Brockman 4 Operations Village, and is part of the wider Nammuldi Below Water Table project, in the West Pilbara.
Earlier this year the miner announced a $3.1 billion commitment to expanding its Australian iron ore operations.
The majority of the investment was used to extend the life of its Nammuldi iron ore mine, with the site receiving a $2 billion boost.
A further $1.1 billion was used on early works to expand the company's Cape Lambert port and rail facilities.
The new contract with OTOC will see it began work immediately.
Adam Lamond, OTOC's CEO, said the "company is pleased with the award of this contract by Rio Tinto".
Earlier this OTOC won another contract for accommodation villages at Rio Tinto's West Angelas mine.
