The Tariff Landed Mid-Project. Your Builders Risk Policy Was Priced Last Year.

The contractor signing a builders risk policy in September of 2025 was, in effect, betting on the cost of steel and lumber holding for the duration of the job. That bet has gone the wrong way.

Since April, the federal tariff schedule has settled at 50 percent on items made entirely or mostly from steel, aluminum, or copper. Derivatives of those metals sit at 25 percent. Industrial and electrical equipment that incorporates those metals — transformers, panel boards, conduit — carries a 15 percent tariff. Softwood lumber sits at 10. Some of those rates are time-limited; most are not. Cushman & Wakefield estimates an aggregate 6 percent cost increase to construction materials versus the 2024 baseline and a 3 percent rise in total project cost, with longer-term aggregate construction cost movement projected at roughly 8 percent. Copper, the line item every electrical and mechanical sub is watching, trades near $5.76 per pound — up roughly 32 percent year over year.

The numbers below the headline are where the discipline question lives.

The contract was written. The policy was priced. The cost moved.

AGC's 2026 contractor survey found that roughly 70 percent of firms report being directly affected by current tariff policy. Sixteen percent have already canceled or postponed projects. Forty-one percent have raised bid prices on new work. Thirty-nine percent have stockpiled materials. Only twenty percent have added contractual price-sharing terms.

That last number is the one that should make a contractor pause. Construction Owners Magazine puts the math plainly: a 20 percent rise in key materials can eliminate roughly half of expected profit on a typical job. Tariff exposure is not an academic question; it is a margin question. And the contractor who finished bidding in late 2025 — without an escalation clause — is absorbing the move alone.

ConsensusDocs publishes the only standard material-price escalation rider in the U.S. market: the 200.1 Material Price Escalation Amendment. It names the affected materials, sets an objective index, defines a sharing threshold, and structures resolution without litigation. It is not new. It is, however, the difference between a 2026 project that survives a tariff shift and one that quietly funds it.

The builders risk problem most people do not see

There is a second layer underneath the contract — the insurance layer — and it does not adjust on its own.

Most builders risk policies carry a 100 percent coinsurance clause. The contractor who bound a $3 million project value last fall, and is now building the same scope at a $3.4 million replacement cost, has not just absorbed a cost shock. He has — under the plain language of the policy — quietly underinsured the project.

This is the gap that is hiding inside thousands of active programs right now. The contractor saw the headline cost move. The CFO saw it. The carrier did not get a midterm endorsement to follow. The next storm, fire, or theft event proves the gap exists.

The broader market is split — which is the opportunity

Heading into the back half of 2026, the construction insurance market is not one market. It is two.

WTW's Insurance Marketplace Realities 2026 and Lockton's mid-2026 update agree that commercial auto liability is up 8 to 20 percent on contractor accounts. General liability is moving mid- to high-single digits, more in tort-heavy jurisdictions. Excess liability is tighter — Burns & Wilcox notes contractors who once carried a $25 million umbrella are now being offered $10 million as nuclear-verdict severity continues to climb. At the same time, workers comp is running flat to plus three. Inland marine is competitive. Property — yard, shop, office — is softening for clean operators.

A split market rewards the buyer who engages it line by line. It punishes the buyer who renews on autopilot.

The discipline window

This is the part PFTN was built for.

The runway question is not whether to chase a lower rate on commercial auto in a hardening segment. It is whether the contract clause, the builders risk limit, the wrap-up reporting basis, the umbrella attachment, and the equipment schedule are still telling the same story they told twelve months ago. They are not, in most cases. The tariff moved. The verdict environment moved. The market split.

The torch question is simpler. What does the policy actually do in October if a storm hits the project, the steel package has gone up 32 percent, and the contract has no escalation clause? If the answer is unclear, the answer is the work.

Insurance is not a discount. It is a discipline. The contractor who treats mid-year 2026 as a strategic checkpoint — not a renewal task — is the contractor whose program holds the next time the price of a beam moves overnight.
