Construction Input Costs Outpaced Bid Prices by 4.9 Points in May 2026. Small Subcontractors Are Absorbing the Difference.

By George Carrillo, CEO, Hispanic Construction Council | July 9, 2026

In May 2026, construction input costs for new nonresidential projects rose 8.4% year over year. Contractors' bid prices rose 3.5% over the same period. The 4.9-point gap between those two numbers is not a rounding error. It is where margin goes to disappear.

This is the operating reality that small construction firms, and particularly the Hispanic-owned subcontractors and specialty trades firms that make up a significant share of this industry's workforce, are managing on every active project right now. The spread between what you pay and what you can bill is structurally wider than it was twelve months ago. Tariff uncertainty on steel, aluminum, and copper is keeping it from closing.

Construction Input Cost Data: May 2026

The Associated General Contractors of America published a producer price analysis on June 11, 2026 that breaks down where the pressure is coming from. Diesel fuel rose 105.9% year over year through May. Aluminum mill shapes are up 48.8%. Copper and brass mill shapes are up 26.8%. Structural steel mill products are up 15.6%. These are the inputs that go into virtually every nonresidential construction project, from light commercial framing to industrial buildouts to public infrastructure.

Against that backdrop, the overall input index to new nonresidential construction rose 8.4% year over year through May. Contractors' bid prices, the number on the other side of the margin equation, rose only 3.5% over the same period. The spread is real and it is sustained. This is not a one-month spike.

The tariff situation adds a layer of uncertainty that makes forward pricing harder than it would be in a stable commodity environment. AGC's Tariff Resource Center, last updated June 30, 2026, describes the situation as fluid. That means a contractor pricing a project in July cannot rely on current material costs to hold through a six- or twelve-month project cycle. The aluminum and copper numbers are already substantially elevated. Whether they stabilize, rise further, or correct depends on trade policy decisions that are not within the contractor's control.

Why Small Subcontractors Absorb This Differently

Hispanic workers make up 35.2% of the U.S. construction workforce, according to the HCC 2026 State of Hispanic Construction Report. The Hispanic-owned businesses in this industry are disproportionately concentrated in subcontracting and specialty trades. They take work through general contractors, not directly through owners. That structure means their pricing power runs through the GC's bid, not their own direct negotiation with the client.

When inputs rise faster than bid prices, the question is who absorbs the gap. Large general contractors and well-capitalized specialty firms have several mechanisms: escalation clauses in owner contracts, multi-project purchasing leverage that allows volume buying before a price spike, and lines of credit that let them carry the cost impact across quarters. Small subcontractors, in most cases, have none of those three things.

A welding subcontractor in Arizona who buys welding wire and gases at whatever the spot price is on purchase day, works under a fixed GC subcontract, and does not have a revolving credit line has no mechanism to transfer a 48.8% aluminum cost increase to the project owner. It comes out of the job.

The Compounding Effect of Tariff Uncertainty

The tariff layer is not primarily about current prices. Current prices are bad enough. The tariff problem is about forward visibility. A firm bidding a project that begins in September and runs through March 2027 cannot price with confidence on the aluminum, copper, or steel line items because the tariff environment on those materials is still being contested in trade negotiations, regulatory proceedings, and product exclusion requests.

The result is that small subcontractors face a choice between bidding low enough to be competitive and absorbing cost risk, or pricing in a buffer that makes them uncompetitive against larger firms with actual hedging capability. Neither option is clean. The firm with real purchasing scale and better credit can price more aggressively because it can absorb a variance or buy forward. The smaller firm prices it wrong in either direction.

What to Do in This Environment

First, recalculate the cost basis on any bid you submitted before April. The diesel, aluminum, and copper numbers have moved substantially since Q1. If you submitted a fixed price without an escalation provision and work has not started, the time to renegotiate is before mobilization, not after the first delivery invoice lands.

Second, identify which line items in your active backlog have the most tariff exposure. Structural steel, aluminum, and copper are the categories with the most volatility. For any contract with these materials as a significant cost component, know whether you have price pass-through language or whether you are holding the risk yourself.

Third, check AGC's Tariff Resource Center directly before the next bid. The resource is updated as the tariff situation evolves. Given how quickly the data has moved in 2026, a bid priced on information that is 60 days old is a bid priced on the wrong market.

The Structural Problem

The 4.9-point input-to-bid-price spread is not uniquely a problem for Hispanic-owned firms. It is an industry-wide condition. But industry-wide conditions land differently depending on firm size, contract structure, and capitalization. The firms least equipped to absorb a sustained margin squeeze are the same firms that have historically operated with the thinnest margins and the least access to the financial tools that larger competitors use to manage commodity risk.

The HCC 2026 State of Hispanic Construction Report documents a construction industry that is 35.2% Hispanic by workforce share. The business side of that workforce is concentrated in the segments of the market that have the least protection against exactly this kind of sustained cost pressure. That is not a problem that resolves when the tariff situation eventually settles. It is a structural exposure that requires structural attention.

Frequently Asked Questions

### Why are construction input costs rising faster than bid prices in 2026?

The Associated General Contractors of America's June 2026 producer price analysis shows inputs to new nonresidential construction rose 8.4% year over year through May while contractors' bid prices rose only 3.5%. The input side is driven by diesel fuel up 105.9%, aluminum up 48.8%, copper up 26.8%, and structural steel up 15.6%. The bid price side reflects competitive market pressure and the lag between when input costs spike and when those costs can be priced into new contracts.

### How do tariffs affect small construction subcontractors?

Tariff uncertainty on steel, aluminum, and copper makes forward pricing harder for small subcontractors who lack the purchasing leverage to buy ahead of price increases or the credit to absorb cost variances across a project cycle. Larger firms can hedge through volume purchasing and financial instruments. Small subcontractors typically cannot.

### What should Hispanic contractors do about rising material costs?

Review any outstanding fixed-price bids submitted before April 2026 against current material costs. Identify which active contracts have significant steel, aluminum, or copper exposure and whether those contracts include cost pass-through provisions. Check AGC's Tariff Resource Center before each new bid to use current data.
