1. Research summary

Delivering through disruption: Currie & Brown Construction Certainty Index 2026 is based on research conducted by Sapio Research in June 2026, surveying 1,310 senior decision-makers involved in construction and infrastructure planning.

Participants were from the healthcare, high-tech, education, real estate, hospitality, pharmaceuticals, and renewable energy sectors. They represented organisations from 20 to 10,000+ employees, across the UK, Europe, the Americas, and Asia Pacific.

The findings provide a global snapshot of how uncertainty is affecting construction pipelines, investment in sustainability, technology adoption, and overall project confidence.

2. Average pipeline loss—methodology

We asked respondents precisely how much uncertainty increased costs across their total construction pipeline over the past 12 months. The average cost increase was 12.4%.

3. Global loss estimate—methodology

To project the wider impact, we extrapolated survey findings to a global level. S&P Global forecasts that global construction spending will reach $15.9 trillion in 2026.

We know that the average percentage costs across the pipeline due to uncertainty over the past 12 months is 12.4%. To estimate the costs incurred within the existing market, we multiply $15.9 trillion by 0.124 to give us the cost of uncertainty within project pipelines globally.

4. Currie & Brown Construction Certainty Index—methodology

The Currie & Brown Construction Certainty Index measures confidence in delivering projects on time, on budget, and in line with evolving priorities such as sustainability and innovation.
