WASHINGTONAssociated Builders and Contractors reports today that its Construction Backlog Indicator rose to 8.0 months in May, according to an ABC member survey conducted from May 20 to June 2, 0.1 months higher than in April 2021 and May 2020.

While ABC’s Construction Confidence Index readings for sales increased modestly in May, confidence regarding profit margins and staffing levels slipped. All three indices remain above the threshold of 50, indicating expectations of growth over the next six months.

“Nonresidential construction backlog continues to edge higher, consistent with expectations that sales, profit margins and staffing will expand over the next six months,” said ABC chief economist Anirban Basu. “For at least four reasons, this represents an extraordinary set of findings.

“First, materials prices have risen significantly over the past year and labor costs are also on the rise,” said Basu. “All things equal, one might think this would suppress profit margin growth. Apparently, demand for construction services is strong enough to generate sufficient pricing power to more than fully countervail those factors. Second, skills shortages continue to impact the construction industry and many other segments. Despite that, the average nonresidential contractor expects to expand their teams during the months ahead.

“Third, conventional wisdom suggests that commercial real estate fundamentals are weak in the context of remote working, online shopping and sluggish business travel,” said Basu. “Nonetheless, backlog in the commercial category remains stable. Fourth and finally, while there has been much talk about a federal infrastructure plan, it remains elusive. Nonetheless, backlog in the infrastructure category rose significantly in May, perhaps a reflection of stronger state and local government balance sheets and associated increases in infrastructure outlays. In sum, contractors can expect healthy growth in activity through the balance of 2021.”
