Monadelphous Group has secured a number of contracts across Western Australia with BHP as part of a package of construction and maintenance agreements worth circa-A$110 million ($75 million).

The news comes on top of existing maintenance and other contracts the company has previously secured with the major mining company.

These include a contract at the BHP-owned Mining Area C iron ore mine site in the Pilbara, where Monadelphous will provide upgrades to existing conveyer equipment, and power switching and stackers. Work is expected to be completed in the September quarter of 2020.

The engineering firm has also won a contract for the provision of services associated with the demolition and rehabilitation of a number of end-of-life facilities at Nelson Point in Port Hedland. This contract is expected to commence in January 2020 and will be completed in the September quarter of 2020.

Monadelphous will also carry out a 12-month extension to its existing contract with BHP’s Nickel West division for the provision of maintenance, shutdowns and off-site repair services at the Kalgoorlie nickel smelter.

Lastly with BHP, the company has been awarded a contract with thyssenkrupp Industrial Solutions (Australia) for the construction of a reclaimer and two stackers at BHP’s South Flank project in the Pilbara. thyssenkrupp has previously said these will be the largest rail mounted stacker/reclaimers in the world, with a loading capacity of 20,000 t/h.

Monadelphous’ work is expected to be completed in the March quarter of 2021.

In Queensland, meanwhile, the ASX-listed company has secured a three-year contract for the provision of general mechanical and maintenance services as part of Incitec Pivot’s scheduled turnarounds for its Queensland manufacturing facilities, it said.
