Monadelphous Group Limited (ASX:MND) has announced a package of new contract awards with a combined value of approximately $150 million, spread across three of Australia's best-known resource producers. The engineering group disclosed the work on 28 October 2026, naming Rio Tinto, BHP and Whitehaven Coal as the clients. The awards cover marine infrastructure maintenance in Western Australia, temporary facilities for a Pilbara project and shutdown services at coal operations in two states. Each contract is described below, along with the divisions and locations through which the company operates.

Rio Tinto Port Maintenance Extended to Four Years

The first award is a four-year contract with Rio Tinto for maintenance services and minor projects on the miner's marine infrastructure. The work is located at the Dampier and Cape Lambert ports in Western Australia.

Monadelphous describes the contract as a continuation of services it already provides, which means the company has been working on this marine infrastructure ahead of the new term. The four-year length is the longest of the three awards, as the BHP contract is tied to a project completion date and the Whitehaven Coal contract runs for three years with an option to extend.

The scope is a mix of ongoing maintenance and smaller projects rather than a single construction build. No individual dollar figure was provided for this contract, and the approximately $150 million value applies to the combined awards.

BHP Ministers North Work and Whitehaven Coal Shutdowns

The second award comes from BHP and is associated with the Ministers North Project in the Pilbara region of Western Australia. The work involves establishing and maintaining temporary non-process infrastructure facilities, along with associated services. Monadelphous expects the contract to be completed by mid-2028, giving it a defined end date that sits roughly one and a half years after the announcement.

The third award is with Whitehaven Coal. Monadelphous has secured a three-year contract, with a two-year extension option, to continue providing shutdown services across the miner's mine sites in Queensland and New South Wales. If the extension is taken up, the relationship would run for five years in total. As with the Rio Tinto port work, the Whitehaven Coal contract continues an existing service relationship instead of opening a new one.

Taken together, the work spans Western Australia, Queensland and New South Wales, and the company grouped the awards as new contracts for resources customers.

How the Company Is Structured

Monadelphous describes itself as an Australian engineering group with more than 50 years of experience, providing construction, maintenance and industrial services to the resources, energy and infrastructure markets. It reports through two operating divisions. Engineering Construction handles large-scale, multidisciplinary and vertically integrated project management and construction services.

The second division, Maintenance and Industrial Services, specialises in planning, managing and executing mechanical and electrical maintenance, shutdowns and sustaining capital works. The three new awards fit mainly within that second description, since maintenance services, minor projects, shutdowns and temporary facility services are the types of work it lists.

The company is headquartered in Perth, Western Australia, with a major office in Brisbane, Queensland. It also has offices, projects, facilities and workshops across Australia and in China, Mongolia, Papua New Guinea, Vietnam and the Philippines.

Where the Announcement Leaves the Company

The announcement adds approximately $150 million of contracted work across three clients, with terms that range from completion by mid-2028 to a four-year port maintenance agreement and a three-year shutdown agreement that carries a two-year option. Two of the three awards continue services that Monadelphous already delivers to Rio Tinto and Whitehaven Coal, while the BHP award relates to the Ministers North Project in the Pilbara. The company did not break the $150 million figure down by contract, so the split between the three clients remains undisclosed.
