The civil and mining contractor will carry out works at the Western Turner syncline stage 2 project west of Tom Price in Western Australia.
As part of the deal the company has made agreements with a number of Pilbara Aboriginal business partners, who they will work with to deliver on the contract.
Brierty managing director, Peter McBain, said the contract was a major achievement that recognised the company's multi-disciplined capabilities.
Brierty reported a net profit of $4.4 million in the first half of the 2014 financial year.
