Are construction projects in your community becoming more expensive or harder to complete?

Infrastructure and advanced manufacturing projects led U.S. construction activity in 2026, even as office and hospitality sectors lagged. Rising litigation and defense costs have simultaneously pushed casualty losses higher despite stable general liability pricing.

Why it matters

Operators face project schedules extended by persistent labor and material shortages, necessitating more complex insurance coordination. Rising casualty losses from social inflation mean contractors must monitor defense costs and legal trends to protect project margins.

General liability insurance premiums saw low- to mid-single-digit growth during 2026, a stable trend that contrasts with rising casualty losses. These losses are currently driven by increasing litigation funding and elevated defense costs.

The details

Contractors are shifting toward admitted insurance placements as project risks migrate from excess and surplus lines. Brokers are concurrently managing extended coverage windows caused by project delays from component shortages. To maintain margins, operators are seeking alternative material sources and preparing for AI-driven project management tools projected to impact timelines in 2027.

Market Landscape

The U.S. construction sector is currently defined by the rise of social inflation in casualty insurance underwriting, which is increasing total losses despite flat premiums. This shift marks a departure from typical insurance cycles where general liability usually mirrors broader property market movements.

Owners should factor increased litigation defense costs into project budgets and discuss casualty coverage limits with their brokers. Contractors must also maintain flexible project schedules to account for component shortages and the ongoing scarcity of skilled labor.

The takeaway

The construction sector is experiencing a period of modest, highly selective growth that demands tighter control over insurance and labor variables. Operators should review their current insurance placements to ensure coverage matches the migration of risks toward admitted market products.
