Construction contractors continue to operate in an environment where pricing certainty can disappear quickly. Material volatility, tariff changes, freight disruption, regulatory shifts, manufacturer delays, and labor constraints can all affect project cost and schedule after a contract is signed. That risk is especially significant in exterior envelope work, where projects often depend on products with metal, petroleum, insulation, membrane, or imported components.
The issue is not limited to whether material prices are generally rising. The more important legal question is who bears the risk when project costs change after the bid. Associated Builders and Contractors reported that construction input prices increased in early 2026, with non-residential construction input prices also higher year over year. ABC also attributed part of that pressure to tariff-affected materials. AGC has likewise warned contractors that tariffs and construction material price changes require careful contract planning, including attention to escalation and procurement terms.
For contractors, a fixed-price contract can become dangerous when the contract assumes a stable market that no longer exists. If the agreement does not include a price escalation clause, substitution right, or material availability protection, the contractor may be forced to absorb increased costs that were neither reasonably anticipated nor included in the bid. That problem becomes worse when the owner delays approval, a design professional rejects a reasonable substitution, a manufacturer extends lead times, or a public authority changes requirements after contract execution.
Contractors should focus on four areas. First, price escalation clauses should identify the affected materials, the triggering event, the proof required, and the method for adjusting the contract price. A good clause should cover tariffs, duties, taxes, freight surcharges, manufacturer increases, and extraordinary market changes. Second, procurement language should allow the contractor to order long-lead materials promptly and require timely owner approval of submittals. If the owner delays approval, the contractor should receive a time extension and price adjustment.
Third, contracts should include a change-in-law or regulatory-change provision. New laws, code interpretations, agency directives, or other governmental actions can increase cost or delay performance. The contractor should not bear those impacts when they occur after the contract date and were outside the contractor’s control. Fourth, substitution language should give the contractor a practical path to use comparable materials when specified products become unavailable or commercially unreasonable.
Documentation remains critical. Contractors should preserve supplier quotes and communications showing when pricing or availability changed. Without that record, even a strong contract clause may be difficult to enforce.
👉 Takeaway: Contractors should not rely on general force majeure language to protect them from material volatility. Force majeure may help with delay, but it often does not provide a price adjustment. Contractors should use targeted clauses addressing price escalation and regulatory change. In the current market, the party that controls the contract language often controls who absorbs the price increase
