Macmahon secures $144m in new contracts

Decmil, a subsidiary of Macmahon Holdings (ASX: MAH), has secured new civil contract awards with HanRoy, Rio Tinto (ASX: RIO) and Glencore.

HanRoy has awarded Decmil a $104m contract for HanRoy’s Marble Bar Road Upgrade Project in WA.

The contract for sections 5 and 2B covers about 46km of road construction upgrade works to Main Roads WA standards on Marble Bar Road. Works are expected to commence in August 2025 for an eight-month period.

Decmil managing director and chief executive Michael Finnegan comments on the award.

“We are very pleased to have been awarded additional works at the Marble Bar Road Upgrade project where we have been working closely with the HanRoy team for the past eight months on section 3, the middle 23km, which will be completed this year,” he said.

“Macmahon values our relationship and are excited to continue building on this.”

Decmil has also been awarded a $28m contract to deliver Stage 2A of the Jerriwah Village Expansion Project at Rio Tinto’s Brockman 2 mine located in the West Pilbara Region of WA.

The project involves the installation of supplied accommodation modules, laundry facilities and a gymnasium.

Decmil will also design, supply and install a new multi-sports court facility and other outdoor amenities.

Works are set to commence in mid-2025 with completion expected in 2026.

Mr Finnegan says it is great to see Decmil continue to secure new work, providing a solid foundation for FY26 work in hand.

“We have an extensive track record in delivering accommodation village design and construction projects and look forward to delivering another at Jerriwah for Rio Tinto,” he said.

“I would like to thank our team for their dedication and support in building a trusted relationship with Rio Tinto and we look forward to strengthening this in the years ahead.”

In addition to these recent wins, Decmil has signed a $12m contract with Glencore to perform earthworks and civil works at the Rolleston Open Cut mine in Queensland.

The initial works are expected to be completed by early 2026 under a schedule of rates agreement.
