Two are in the mining space and one is the Victorian government.

One of the mining contracts involves conducting early works on Rio Tinto's Western Range project about 8km west of Paraburdoo in Western Australia's Pilbara.

That job is expected to bring MACA about $60 million in revenue.

The project pre-approval works consist of building a camp pad and access road along with crushing and screening work.

The works will start in the second half of 2022 and go for about 12 months.

The other mining sector win is at Roy Hill's eponymous mine, 115km north of Newman in the Pilbara.

The package consists of supporting Roy Hill with the Sierra Hydraulic Structure works and is expected to generate $16 million in revenue.

Those works start this month and should run through to the end of the calendar year.

The work with Major Road Projects Victoria involves building the eastern package of the Hall Road Upgrade and is expected to deliver $40 million in revenue.

This is MACA's second contract with MPRV. It follows the award of the Golf Links Road Upgrade, which MACA is delivering.

Incoming MACA CEO David Greig said the company looked forward to delivering the projects.

"These awards re great examples of MACA's deliberate pursuit of capital light earnings, revenue diversity and attractive delivery models," he said.
