One contractor, three states: how Australian clients started buying builders as advisers

Four major Australian projects have appointed a contractor to a role that is not construction:

• Osborne Submarine Construction Yard — Laing O'Rourke and Amentum appointed Capability Partner in July 2026, working inside Australian Naval Infrastructure's Integrated Delivery Office across governance, assurance, logistics, commissioning, digital engineering and supply chain
• Queensland's Games venue program — the Unite32 consortium of Laing O'Rourke and AECOM appointed Delivery Partner in December 2025 for the planning and delivery of 17 Olympic and Paralympic venues

• Melbourne Airport Third Runway — McConnell Dowell and Lendlease engaged as construction advisors
• VNI West — Iberdrola Australia appointed Development Partner by VicGrid, with a build-own-operate role contingent on performance during the development phase

Add Bechtel holding both delivery partner and project management on Western Sydney Airport, and a pattern is visible. Clients are buying contractor expertise before, and separately from, contractor delivery.

Why clients are doing it

The logic is sound, and it is a response to a real problem.

Client-side capability has thinned. Government agencies delivering megaprojects need commercial, program and engineering expertise that is expensive to retain between projects. Buying it from a contractor is faster than building it.

Programmes need coordination that individual contracts cannot provide. Unite32's remit across 17 venues is the clearest case: no single venue contract could coordinate 17 procurements, and the alternative is a large client-side organisation built from nothing.

Complex projects benefit from constructor input early. A capability partner at Osborne brings buildability, logistics and commissioning knowledge into a nuclear-capable shipyard that has no Australian precedent — before the design is fixed.

This is Early Contractor Involvement extended to its logical conclusion: not a contractor helping design the job it will build, but a contractor helping run a program it may never build.

The question nobody is answering publicly

Can an adviser bid the work it has shaped?

On each of these projects the answer matters, and on none of them is it clearly stated in the public record.

• Can Laing O'Rourke bid construction packages at Osborne while holding the Capability Partner role?
• Can Unite32's members bid individual Games venues while coordinating the program?
• Can McConnell Dowell or Lendlease bid the Melbourne Airport runway they advised on?
• Iberdrola's position is at least explicit: it may be appointed to build, own and operate VNI West, contingent on development phase performance. That is the model stated honestly.

There are legitimate ways to handle this — information barriers, express exclusions, or Iberdrola's approach of naming the pathway upfront. What is unusual is how little is said about it.

For subcontractors the question is immediate and practical: if you are positioning with a head contractor, does the adviser's involvement mean the packaging is already set? On a program like Unite32's, the answer shapes 17 venues' worth of subcontract structure.

The concentration problem underneath

The same firms recur, and the pattern is not confined to advisory roles.

Across the projects covered by this masthead, CPB Contractors and UGL appear in shortlists, consortia or awards on the M6, Cross River Rail, Hunter Transmission, Marinus Link, Gold Coast Light Rail, Melbourne Airport Rail, North East Link and ACT Light Rail. ACCIONA appears on Alkimos, Eyre Peninsula, Sydney Metro West tunnelling, Hunter Transmission and Coomera Connector bridge components. John Holland appears on Sydney Metro West, Gold Coast Light Rail, Brisbane Stadium and ACT Light Rail.

This is not a criticism of those firms. It is what a market produces when projects are large enough that bidding requires a consortium, and only a handful of firms can anchor one.

But layering advisory roles on top of that concentration compounds it. A firm that advises on program structure, sits in delivery consortia elsewhere, and bids construction work is occupying three positions in the same market — and the boundaries between them are managed privately.

What it means if you are further down the chain

Packaging decisions are being made earlier, by parties you may not be tracking. If a delivery partner is shaping how 17 venues are carved into contracts, the time to understand that structure is while it is being designed — not when tenders are released.

The adviser is a relationship worth having. Whether or not they bid, they know the program, the sequencing and the client's constraints better than most head contractors will.

Ask the question directly. Whether an adviser can bid the work is a legitimate thing for a subcontractor to ask a client or a head contractor. The answer determines who you should be positioning with.

What would improve it

State the position publicly at appointment. Iberdrola's VNI West arrangement does this: the pathway from Development Partner to build-own-operate is named, and it is conditional on performance. Everyone bidding around it knows where they stand.

Publish the probity arrangements. If information barriers or exclusions apply, saying so costs nothing and removes the question.

Neither requires a change to how the model works. Both would let the rest of the market plan around it.

What to watch

1. Whether any adviser wins delivery work on the project it advised, and how that is handled.
2. How Unite32 packages the 17 Games venues, which is the largest single application of the model in the country.
3. Whether Osborne's supply chain access — explicitly part of the Capability Partner remit — opens to firms outside the usual field.
4. Whether the model spreads to state road and water programs, which have so far kept client-side capability in-house.
