Clough last worked at Alcoa's Wagerup facility in 1990, Clough CEO and managing director Peter Bennett said, and it welcomes the opportunity to work on this new project at the site.
The Wagerup alumina refinery commenced operations in 1984 and has an annual production capacity of 2.5 million metric tonnes.
It is located approximately 150km south of Perth on the border of Western Australia's Peel and South West regions.
It is supplied with bauxite ore from Alcoa's Willowdale bauxite mine, which is located east of Waroona.
Bennett added: "The engineering and construction of this facility will be self-performed. The scope includes civil, structural, mechanical, piping, electrical and instrumentation and aligns with our strategy of developing our complimentary service offerings."
