The construction industry is grappling with the impact of extreme heat on productivity. During periods of extreme heat, construction activities involving physical labor take 36% longer to complete, according to an analysis by nPlan. Rising temperatures are also a major safety concern for workers. Heat is one of the three main causes of worker deaths in the U.S. This summer, construction crews across the country faced challenging working conditions during heat waves, leading firms to adjust work hours, provide shade and cooling stations, and distribute Popsicles. As temperatures continue to rise, construction companies may need to add more workers during cooler hours or offer more breaks, potentially affecting project scheduling and costs. The impact of heat on productivity is expected to become more pronounced as temperatures continue to rise and the average age of the construction workforce increases.
