The contracts are for construction of a $125 million coal-handling and preparation plant (CHPP) and a rail loop and holding roads project worth about $95 million.
Thiess executive general manager construction Ric Buratto said the two new contracts illustrated the strong collaboration that thrives within Thiess.
“We’re proud of what we call the one-Thiess approach to delivering diverse projects,” he said.
Site preparation and drainage works are already underway at the site, with the CHPP contract to be delivered by the firm’s specialist industrial projects team.
The rail contract includes engineering design. Earthworks and excavation will be done before the track is laid and signals installed. Overhead power and communications systems will then be installed.
Thiess is a subsidiary of Leighton Holdings.
