Monadelphous Group (MND) has won a substantial contract with Rio Tinto (RIO) for construction work at the miner's Cape Lambert project in Western Australia.
In a statement to the Australian Securities Exchange, Monadelphous said the contract, valued at around $235 million, was for structural mechanical and piping works for the supply and installation of a screenhouse, two car dumpers and associated conveyor and transfer stations.
"This award builds on our long-term relationship with Rio Tinto," Monadelphous managing director Rob Velletri said.
"We look forward to the successful delivery of another large-scale project which continues our extensive support for Rio Tinto in the expansion and maintenance of its Pilbara iron ore operations over many years."
Construction work is scheduled to be completed by the fourth quarter of calendar 2014.
Monadelphous said the contract award would "support solid sales revenue momentum into the new financial year".
