Survey Reveals 79% of Construction Firms Report Heat-Related Incidents, Escalating Temperatures

A new survey commissioned by Perry Weather reveals extreme heat is creating critical safety and efficiency vulnerabilities on construction sites.

The report, “Under Pressure: How Extreme Heat Is Reshaping Construction Safety,” found that nearly eight in 10 U.S. construction leaders reported heat-related incidents at their jobsites in the past year. The findings reveal a growing crisis where rising temperatures are costing companies millions in delays, turnover and safety risks.

The survey of 250 construction leaders, conducted by independent research firm TrendCandy, exposes the financial and human costs of rising temperatures. Key findings indicate a systemic challenge impacting projects from start to finish:

• Productivity in Peril: 89% of construction leaders observed productivity losses during high-heat days, averaging 4-6 hours of downtime weekly
• Worker Retention Crisis: Heat safety is now a critical factor in workforce stability, as 65% of firms have had workers leave jobs due to concerns over inadequate heat safety
• Significant Financial Impact: The average cost of a single heat stress incident is between $5,001 and $10,000, highlighting a major financial incentive for proactive mitigation
• The Policy-Practice Gap: Despite widespread monitoring, 49% still struggle to enforce heat safety policies;13% admit to having no written heat safety policy.

“The data is clear: hoping for cooler days is no longer a viable business strategy,” said Colin Perry, CEO of Perry Weather. “The gap between having monitoring tools and enforcing safety protocols on the ground is where injuries happen, projects stall and skilled workers walk away. This report is a wake-up call for the industry to move from a reactive to a proactive stance on heat safety.”

The survey also uncovered cultural challenges, with 48% of workers ignoring protocols due to deadline pressure and 35% admitting they don’t want to appear weak. This indicates that technology and policy alone are insufficient without a supportive safety culture.
