Downer EDI has won a $50 million contract for work at Rio Tinto's Warramboo project in the Pilbara.


The work involves earthworks, concrete works, road surfacing and bridge construction, electrical and communication works, as well as a diversion of the North West Highway near Warramboo, 165 kilometres south of Karratha.


Downer EDI chief executive Grant Fenn said the contract win demonstrated Downer's ability to provide customers with comprehensive design and construct services for civil mine infrastructure including roads, bridges, buildings and utilities.


The project is scheduled for completion in April next year.
