The construction labor math keeps getting worse. Associated Builders and Contractors estimates the industry needs roughly 349,000 net new workers in 2026 just to keep up with demand, and it projects that figure climbing to 456,000 in 2027. Those are net numbers, on top of replacing everyone who retires or leaves.
The gap isn’t new. What’s new is the direction of the workforce, which is shrinking in places at the same time demand holds up. Immigrants make up about 34% of construction workers nationwide, and their share tops 60% in the finishing trades: drywall, roofing, plastering. Those are the crews that hang and finish a building after the structure tops out, and they’re the hardest to backfill quickly.
Enforcement is showing up in the numbers
A joint survey by the Associated General Contractors and the National Center for Construction Education and Research found 28% of construction firms had workforce disruptions tied to immigration enforcement activity within the prior six months. About one in ten contractors said they lost workers directly to enforcement actions. Whatever your politics, the operational effect on a schedule is the same: a framing or drywall crew that was there Monday isn’t there Wednesday, and the follow-on trades stack up behind them.
No quick fix on the supply side
Training pipelines are expanding, apprenticeships are getting funded, and robots are starting to take the most repetitive tasks, as they’re doing on rebar and brick. None of that closes a 349,000-worker gap this year. Craft workers take years to develop, and a robot that ties rebar doesn’t hang a door. For now, the firms winning the labor fight are the ones paying up, training their own, and treating retention as a jobsite metric rather than an HR footnote.
