Key takeaways and global construction cost trends in this report

Construction markets are entering a new phase where clients need to take greater control to ensure successful project outcomes. As investment becomes increasingly selective, organizations need greater confidence in where, when, and how they deliver projects. The International Construction Costs 2026 report explores the market conditions shaping delivery certainty across 100 global cities, helping clients make more informed investment decisions and better manage cost, risk, capacity, and program delivery.

Construction cost is one of many aspects of the project viability challenge. Cost, delivery risk, market capacity, and investment confidence are increasingly converging, making a broader understanding of market conditions essential to successful project delivery.

Affordability, financing costs, geopolitical uncertainty, and supply-chain resilience continue to influence project viability, requiring clients to balance commercial objectives with delivery confidence.

Delivery certainty is an essential element of competitive advantage. Organizations that integrate cost, schedule, procurement, and risk planning earlier in the project lifecycle are better positioned to improve project viability and delivery outcomes.

Lower construction costs do not necessarily mean lower delivery risk. Market readiness, permitting, power availability, specialist skills, and supply-chain capacity remain critical factors when evaluating where to invest.

Investment is becoming more selective, with capital continuing to flow toward sectors that support long-term growth, including data centers, advanced manufacturing, healthcare, laboratories, workplaces, and digital infrastructure.

Taking greater control starts with better information. High quality design, early cost intelligence, scenario planning, procurement strategy, and collaborative delivery approaches help organizations respond more effectively to changing market conditions and improve long-term project performance.

International construction costs remain highest in mature, capacity-constrained markets, with Geneva retaining its position as the world's most expensive city to build, followed by London and Zurich.

Together, these insights demonstrate that the most successful projects can be delivered in any location, where organizations have confidence founded on informed decisions and the capability to manage complexity throughout the project lifecycle. Combining global market intelligence with deep expertise in project and program delivery, Arcadis helps clients bring together cost, schedule, procurement, risk, and delivery considerations to take greater control of projects: from initial investment decisions through to successful delivery and long-term operational performance.
