Monadelphous said the contracts were with major companies in the Queensland coal sector and the Western Australian alumina and oil and gas industries.
The company has secured work worth $100 million with the BHP Billiton Mitsubishi Alliance (BMA) in Queensland, for dragline and shovel shutdown work across its Bowen Basin coal operations.
Two contracts were also awarded with the BMA Project Delivery Group for ongoing construction work on various sites in the northern region of the Bowen Basin over a two-year period.
Two contracts totalling about $100 million were secured with the Kestrel mine, near Emerald.
Works at the site include civil, structural, mechanical and electrical work to supply and install an overland conveyor as well as a drift conveyor as part of the extension project at the mine.
“[These contracts] demonstrate our continuing involvement in major projects and our commitment to support growth in the Queensland coal industry,” Monadelphous managing director Rob Velletri said.
In WA, Monadelphous scored a three-year contract with the BHP Billiton Worsley Alumina refinery project in Collie.
Monadelphous said the new contract extended the relationship the companies had developed since 2004.
Still in WA, Monadelphous has inked a deal with Woodside to provide mechanical commissioning support for the Pluto LNG plant on the Burrup Peninsula.
In May, Monadelphous was awarded a three-year extension to its existing contract with BHP at the Olympic Dam copper-uranium operation in South Australia and a one-year maintenance services contract with Rio Tinto Dampier Salt in WA worth about $140 million.
The company was also awarded $60 million in new construction contracts, including structural mechanical work for Rio at its Cape Lambert iron ore operation and a contract with MCC Mining for pipe works associated with the concentrator at Citic Pacific’s Sino Iron project.
Monadelphous’ net profit after tax for the December half-year was $45.5 million, up from $40.5 million in the previous corresponding period.
