Perth: Leading Australian engineering company Monadelphous Group Limited (ASX: MND) (“Monadelphous” or “the company”) today announced it has secured a significant construction contract with Rio Tinto Iron Ore for major works associated with Phase I of the Brockman 4 development, in the north west of Western Australia. The contract is valued at approximately $85 million.

The scope of the contract includes structural, mechanical and piping works for the supply, preassembly and installation of the dry processing system which comprises primary crushing, secondary crushing, product screening, stockyards and train load out facilities.

Monadelphous Group Managing Director Rob Velletri said that the Brockman 4 project follows on from a long history of successful projects for Rio Tinto Iron Ore including recent works on the Cape Lambert 80Mtpa and Dampier Port Phase B Upgrades.

“This win reflects both our long term relationship with Rio Tinto Iron Ore and our ability to safely deliver on large scale, engineering construction projects,” he said.

“We look forward to continuing our valued and long term association with Rio Tinto Iron Ore,” added Mr Velletri.

Project works will commence immediately with substantial completion scheduled for the third quarter of 2010.
