Four habits behind the world’s best-run megaprojects

22 September 2026
What the world’s biggest projects teach us about getting delivery right

By Andy Rampton, Field COO, Procore Technologies


McKinsey’s megaproject research makes for uncomfortable reading anywhere in the world: the overwhelming majority of large projects finish over budget and late, and most overruns trace back to execution choices, not bad luck. Here’s the finding that matters most: by the time a contractor mobilises, most of a project’s productivity has already been decided.

That lesson has never been more relevant than in the Middle East, where the UAE and Saudi Arabia are delivering the most ambitious concentrated development programme in modern history. The scale is a once-in-a-generation opportunity, and it puts a global spotlight on a question every owner should ask: what actually makes large projects succeed?

Having spent three decades on major programmes across the UK, US, Asia and the Middle East, I’d offer four ingredients. None requires invention. All require discipline.

1. Be an intelligent client

The outcome of a mega-programme is not decided by contractors. It’s decided by the owner. High-performing owners keep a strong “Intelligent Client” core: they own the requirements, the data standards, the gate decisions and the key commercial positions, and they design their organisation deliberately rather than letting it grow organically. When roles blur across layers of advisers, capable people spend their days reconciling reports instead of making decisions.

2. Engineer productivity at the front end

Capital efficiency cannot be recovered on site through heroics. It must be designed in: honest, resource-loaded baselines; budgets tested against live market conditions rather than historical benchmarks; and a deliverability test before commitment, asking whether the supply chain can actually build what the masterplan imagines. 

A requirement missed at feasibility becomes a design change, then a variation, then a delay, then an operational defect. The cost of correction compounds at every stage.

3. Match the contract to the maturity of the design

Fixed-price contracts on incomplete designs transfer risks that contractors cannot control, and the market prices that risk one way or another. Collaborative, risk-balanced contract forms, with risk sitting with the party best able to manage it, turn the next five years into a partnership rather than a dispute. In a region assembling supply chains at record pace, that choice matters enormously.

4. Build one version of the truth

Industrialised methods and modern construction only pay off when information flows unbroken from feasibility model to factory to field to the operator’s asset register. That means a common data environment from day one, contracted information requirements in every appointment and real-time progress data replacing spreadsheets weeks in arrears. 

Regional data governance frameworks, such as Saudi Arabia’s national data standards, are pushing owners in exactly this direction, and that’s a competitive advantage in the making.

The Gulf’s programmes will shape construction methodology globally. Get these ingredients right and the region won’t just deliver extraordinary assets; it will export the delivery playbook the rest of the world has spent decades failing to write.

It’s time for owners to design productivity in, not inspect it in. The blueprint exists. The Middle East has the scale, the mandate and the moment to build it.
