Construction Backlog Growth Streak Ends in October as Non-Data Center Work Slows

The monthslong growth streak in U.S. construction backlogs came to an end in October as overall project momentum slowed across commercial and industrial building sectors, according to industry survey data released this week.

The national contraction was driven primarily by deteriorating market prospects for the vast majority of contractors operating outside the booming data center construction space. While artificial intelligence and cloud computing infrastructure continue to drive massive capital allocations, conventional private building projects face increasing friction.

"This decline was largely due to worsening prospects for the 88% of contractors not under contract to work on data centers," said Anirban Basu, chief economist at Associated Builders and Contractors. Basu noted that high interest rates and cautious commercial lending continue to delay final investment decisions for traditional builds.

The variance in sector performance underscores a growing divide in the construction industry. While specialized mega-projects maintain high backlog figures, regional builders and general trade sub-contractors report a diminishing volume of new bidding opportunities and extended delays on prospective contracts.

Despite the overall contraction in October indicators, backlog levels across public works and heavy industrial utility infrastructure remained comparatively resilient. However, contractor expectations regarding revenue growth and hiring over the next two quarters have softened alongside the lower backlog numbers.
