NRW has won a $90 million contract as part of Rio Tinto's Yandi Sustaining Project for its Yandicoogina iron ore mine.
The contract will provide bulk earthworks at the Pilbara mine.
Scope of the work, which is designed to expand mine production capacity, includes more than one million cubic metres of excavation; more than 500 000 cubic metres of embankment construction; levee construction, culverts; the construction of a 48 metre long bridge of an operating rail line; and the constructin of two floodways.
The contract is expected to run for around 40 weeks, and is scheduled to begin late next month.
During peak construction there will be around 300 workers on site.
The signing of the contract is positive news for the contractor, following BHP cutting back the scope of its work at Port Hedland, which resulted in a cut of between $75 and $80 million from NRW's existing contracted works.
