The Construction Labor Shortage in 2026: The Numbers Behind the Industry's Binding Constraint
By Virginia Viadas
Materials get the headlines, but ask any general contractor what actually determines whether a project finishes on schedule and the answer is people. Labor remains the industry's most acute structural challenge: roughly 439,000 additional workers were needed in 2025, with nearly 500,000 required in 2026 to meet projected demand, and about 94 percent of contractors report difficulty filling open positions.
The workforce gap in numbers
| Indicator | Figure | Source |
|---|---|---|
| Net new workers needed in 2026 | ~499,000 | Associated Builders and Contractors |
| Contractors reporting hiring difficulty | 94% | Industry surveys |
| Skilled workers over age 45 | Nearly 40% | Industry analysis |
| Workforce projected to retire by 2031 | 41% | Industry projections |
| Change orders cost (partly labor-driven) | ~$44 billion/year in direct costs | Industry estimates |
A demographic cliff, not a cycle
This is not a temporary hiring slump. Nearly 40 percent of skilled construction workers are over age 45, accelerating retirement risk and the loss of institutional knowledge, while an estimated 41 percent of the current workforce is projected to retire by 2031. The shortage compounds itself: skilled trades, superintendents and project managers command premium compensation, making workforce availability a decisive factor in project feasibility.
Policy pressure adds to the squeeze
Immigration enforcement is a construction-specific risk in 2026. AGC chief economist Kenneth D. Simonson warns that aggressive deportations and immigration enforcement will hit construction much harder than most industries, with contractors' major cost concerns centering on availability, quality and wage rates for craft workers.
Where labor scarcity hits hardest
Demand is not evenly distributed. Large-scale data center and manufacturing investment continues to tighten regional labor markets, procurement capacity and availability of critical materials, according to Mortenson's Q1 2026 Cost Index. Regional wage effects are already visible: Chicago construction costs were pushing near double digits year over year, driven more by labor costs than physical inputs, per CBRE-cited data in Urban Land.
The cost of stretched crews
Labor scarcity doesn't just raise wages — it degrades execution. When crews are stretched thin, change orders pile up, costing the US construction industry an estimated $44 billion per year in direct costs, with total rework and delay impact estimated far higher.
What firms are doing
The competitive responses emerging in 2026 include earlier procurement triggered at the estimate stage rather than bid submission, escalation clauses in fixed-price contracts, and real-time job-level cost tracking to catch overruns at the line-item level during construction rather than after final billing. On the demand side, firms that pair realistic budgeting with early procurement, disciplined contingencies and close owner-lender-contractor coordination are the ones positioned to succeed.
FAQ
How many construction workers does the US need in 2026?
Nearly 500,000 net new workers, according to Associated Builders and Contractors — on top of the 439,000 needed in 2025.
What percentage of contractors can't find workers?
About 94% report difficulty filling open positions.
Is the construction workforce aging?
Yes: nearly 40% of skilled workers are over 45, and 41% of the workforce is projected to retire by 2031.
How does the labor shortage affect project costs?
Through wage escalation, selective bidding, schedule risk, and change orders that cost the industry roughly $44 billion annually in direct costs.
