The construction industry is no stranger to challenges, but the recent surge in tariffs on essential building materials—such as steel, aluminum, and lumber—has introduced a new level of complexity. President Trump’s second term in office has been defined, in part, by a series of sweeping trade negotiations aimed at reshoring U.S. manufacturing and reducing trade deficits.
To safeguard against the financial uncertainties introduced by changing tariffs, project stake holders should select the contract pricing model that is most appropriate for the work and carefully negotiate provisions that shift the risk of tariffs to the party best positioned to shoulder the risk.
Contract Pricing Models
Construction professionals are typically familiar with customary pricing models such as fixed price contracts, guaranteed maximum price (“GMP”) contracts, and unit price contracts. For the purposes of this article, we will focus on fixed price and GMP contracts. Before parties jump to negotiating specific clauses, it is important to appreciate how each pricing model carries different implications in a tariff-heavy landscape.
Fixed Price Contracts: Under this model, the contractor agrees to complete the project for a predetermined price. While this model provides cost certainty for the owner, it places the risk of cost increases—such as those arising from tariffs—entirely on the contractor. Absent specific contractual provisions addressing tariff-related cost escalations, the contractor may be compelled to absorb such increases, potentially impacting profitability.
GMP Contracts: In a GMP arrangement, the owner reimburses the contractor for its actual costs incurred plus a fee, with the total not exceeding a specified maximum price. If tariffs suddenly raise material costs, contractors may be forced to absorb the difference, threatening their profitability on the project.
Because both pricing models are premised on setting a ceiling for the cost of the work, it is imperative to address tariff-related risks during contract negotiations, as many standard construction contracts (i.e., American Institute of Architecture forms) are often silent on how to manage such risks. As a result, it is common for parties to revise certain contract provisions to address specific issues, including potential impacts and delays to the work caused by tariffs.
Strategic Contract Provisions to Mitigate Tariff Risks
Before finalizing a contract, project stakeholders should confer with their counsel about how to negotiate specific contract provisions to effectively allocate and manage the risks associated with tariffs, ensuring that the financial impacts of material cost fluctuations are equitably shared and clearly defined.
Advanced Procurement: For projects with long lead times, early procurement of materials can help avoid delays and mitigate the impact of future tariff increases. Contracts should specify procurement timing, storage responsibilities, and insurance requirements. Early procurement is a prudent strategy to avoid seasonal or tariff-driven cost spikes. Parties should confer with their insurance broker to determine whether their builder’s risk policy covers materials while they are in transit and stored off-site. If not, the stakeholders may want to consider purchasing additional coverages to ensure that their long lead items are insured before they arrive at the project.
Contingency Clauses: Incorporating a contingency clause allows parties to agree to increase the overall contract price by a specified amount when certain events occur, such as material price escalations due to tariffs. If the contingency is not exhausted, the savings are typically shared between the owner and contractor. This provision helps distribute the risk of price uncertainty between both parties.
Change-in-Law Provisions: Tariffs are often categorized as changes in the law. Including a change-in-law provision in contracts allows for adjustments if new tariffs are enacted after the contract’s execution. This provision enables contractors to shift the risk of price increases due to new laws to the owner. To ensure entitlement to such adjustments, contractors should ensure that the contract’s change-in-law provisions explicitly include tariff language.
Force Majeure Clauses: Force majeure clauses often cover events labeled as “acts of god,” and include both natural and man-made events like fires, floods, storms, war, and labor strikes. These provisions shift the risks associated with certain unforeseeable events that are not the fault of either party. It is common for these provisions to only address time impacts, and not price adjustments. Like other force majeure events, changing tariffs can cause both delays and cost impacts to contractors. Savvy parties should consider including tariff-specific language in their force majeure provisions, and specify whether the contractor is entitled to additional time and compensation if tariffs impact the contractor’s work.
The imposition of tariffs on essential building materials has introduced significant volatility into Washington’s construction industry. By proactively addressing tariff-related risks through strategic contract provisions and prudent planning, contractors can mitigate potential financial impacts.
