Major cross-border projects used to sell themselves on economies of scale and the promise of geopolitical harmony. Today, contractors and financiers face a messier map. Trade frictions, election shocks and selective export controls now influence everything from steel prices to visa approvals.
A new analysis from Currie & Brown’s Construction Certainty Index 2025 finds builders lost an average 13.7 percent of their global pipeline value last year, equal to US$2.5 trillion (C$3.4 trillion). Only one in five executives felt sure they could still hit budget.
“The new normal is relentless uncertainty,” the Construction Certainty Index says.
Rising risk clouds long timelines
Long schedules magnify exposure. Mega schemes such as Saudi Arabia’s NEOM, budgeted at roughly US$500 billion (C$680 billion), must lock in labour, cement and turbine orders years before first revenue. In the past 12 months, 32 percent of large projects were descoped, 29 percent delayed and 25 percent cancelled. Financing costs also climbed as central banks fought inflation.
Yet demand for new roads, grids and data hubs is still outpacing cancellations. The McKinsey “Infrastructure Moment” report estimates the world needs about US$106 trillion (C$144 trillion) in fresh infrastructure by 2040.
Transportation alone requires US$36 trillion, while energy transition work claims another US$23 trillion. That need is unlikely to vanish, but investors are growing selective about where and how capital is deployed.
Geopolitical fragmentation is pushing planners toward shorter, modular packages that can be relocated or paused if export bans bite. Battery plants, micro-grids and prefab rail stations illustrate the trend.
These assets rely on repeatable designs, smaller footprints and more local supply chains, reducing exposure to any single border crossing. Modular works also mesh with digital tools such as building-information models and predictive maintenance platforms, enabling owners to cut change orders and absorb price swings faster.
At the same time, governments are rewriting procurement playbooks. Flexible risk-sharing clauses now appear in federation contracts across Australia and in public-private partnership templates from Canada Infrastructure Bank.
By balancing inflation and currency shocks between parties, agencies hope to keep bids competitive without over-insuring against every scenario. Early contractor involvement and data-rich dashboards further tighten feedback loops, shrinking the gap between boardroom forecasts and site realities.
“Those who act decisively today will shape the future,” the McKinsey authors argue.
Costs remain high, but so do stakes
Mega projects are not disappearing. They are, however, morphing into networks of smaller, interoperable stages that can prove value sooner and pivot when politics shift. For sponsors, the new calculus blends hard numbers with resilience premiums.
A 20-kilometre tunnel may still justify itself if it unlocks an export corridor, yet backers will now layer contingency funds, local-content targets and off-ramp clauses into every tranche.
Policymakers can draw on global lessons: place certainty, schedule, cost and supply at the centre, and then scale ambition around it. Mega projects remain worth pursuing, but only when their delivery model matches today’s fractured world.
