If you haven't updated your construction budget in the last 90 days, it's probably wrong.
Material costs in 2026 are not just elevated they're moving fast and unevenly. Steel, copper, aluminum, and concrete are all responding to different pressures: tariffs, supply chain instability, and a surge in megaproject demand that's pulling supply away from mid-size commercial work. According to the Associated Builders and Contractors, nonresidential construction input prices surged at a 12.6% annualized rate in just the first two months of this year. That's not a trend line that's a budget problem.
I've seen what happens when developers and owners absorb this reality late. Projects that penciled out in Q4 suddenly face rebudgets mid-design. Fixed-price contracts become stress tests. And the GC who didn't plan for it becomes the messenger nobody wants.
The good news is that this is manageable if you know what to watch and what to do before you break ground.
What's Actually Driving Costs Up Right Now
Before you can protect your project, you need to understand which forces are moving prices. Not all materials are moving the same way and treating them as a single number is how budgets get blown.
Steel and aluminum are the most exposed. Federal tariff policy under Section 232 expanded significantly in 2025 and into 2026, pushing domestic prices higher and creating supply uncertainty. Since early 2020, fabricated structural metal products have risen over 63% cumulatively, according to the U.S. Bureau of Labor Statistics. Aluminum prices alone climbed roughly 40% following tariff increases.
Concrete and cement are a different story, but not a better one. The U.S. imports roughly 20% of its total cement consumption much of it from Canada and Mexico and current tariff structures are hitting those supply lines directly. Estimators who aren't tracking import tariff changes in real time are working with stale numbers.
Lumber had a moment of relative stability in late 2025. That window closed. Supply volatility returned in Q1 2026, and price forecasts have shifted upward again.
The pattern across all of them: costs remain above pre-2020 baselines, move quickly sometimes within weeks and are heavily influenced by policy decisions that aren't always predictable. If your budget assumption is a flat number, it's a risk assumption in disguise.
The 5 Moves That Protect Your Project
This is the part that matters. Understanding the problem is step one. Having a plan before you sign anything is step two.
1. Engage your GC during pre-construction, not after design.
This is the single most impactful decision a developer or owner can make. The window between design completion and construction start is exactly where procurement commitments need to be locked in. A GC engaged during pre-construction can move material orders ahead of price increases, structure bid packages to take advantage of subcontractor competition, and build contingencies that reflect actual market risk not generic estimates. Owners who bring the GC in at contract execution inherit whatever the market has done in the interval.
2. Require price transparency on tariff-exposed scopes.
Structural steel, rebar, metal deck, aluminum storefront and curtain wall, copper wire, and HVAC equipment housings are the most exposed line items in most commercial builds. When reviewing bids, ask for these to be broken out explicitly. Pricing that breaks these scopes out, rather than burying them in a single number, is what prevents disputes later. It is also a fast way to tell which contractors actually understand their exposure.
3. Use escalation clauses and understand what they say.
An escalation clause allows price adjustments tied to real commodity index data typically the BLS Producer Price Index if material costs exceed a defined threshold. Standard thresholds range from 3–5% above the bid baseline before adjustments activate. Steel prices fluctuated 47% between Q1 2024 and Q1 2026. Without an escalation clause in a fixed-price contract, the contractor absorbs that movement. In a market like this, that's not a business risk it's a project risk.
The strongest escalation clauses define a shared adjustment band up front, so both the owner and the contractor know the maximum exposure before anyone signs. Predictability protects the project, not just one side of the table. Ask your legal counsel to review any fixed-price contract before execution, not after.
4. Build a realistic contingency and don't let it get value-engineered away.
A 4–6% material escalation factor on concrete and steel is a reasonable planning baseline for projects starting in Q2–Q3 2026. On coastal and high-demand urban markets, that number pushes higher. A 20% material cost increase on an active project lands hard on both sides. The contractor who won on the lowest number cannot absorb it, which is when owners start seeing it return as change orders. And it hits the developer's pro forma directly when there was no contingency there to absorb it. Budget contingency isn't padding. It's risk management.
5. Know which materials can be substituted and which can't.
Not every spec decision made during design must survive procurement. A GC with strong supplier relationships and subcontractor depth can often identify alternative materials or modified specs that maintain quality and cut exposure on the most volatile categories. This only works if the conversation happens early. By the time you're in the field, those options are mostly gone.
What to Look for in a GC When Costs Are Volatile
This is where the choice of partner matters more than most owners realize.
A contractor who wins work on the lowest number and figures out procurement later is exactly the wrong partner in a market like this one. What you want is a GC with established supplier relationships that pre-date the current volatility, a documented pre-construction process that surfaces cost risk before design is frozen, and the transparency to have uncomfortable conversations about budget early rather than late.
In Texas, where commercial construction demand continues to accelerate, the contractors who are keeping projects on budget are doing it through earlier engagement, better procurement timing, and more disciplined risk communication not by betting on prices coming down.
At Anchor, this is the work we focus on before a single shovel hits the ground. The conversations about material exposure, procurement windows, and contract structure happen during pre-construction because that's the only time they can change the outcome.
The Bottom Line
Rising material costs in 2026 are not going away. Tariffs, supply chain reconfiguration, and sustained construction demand across Texas and the broader U.S. market mean that volatility is structural now, not temporary.
What separates the projects that land on budget from the ones that don't is almost always a pre-construction decision the GC that was engaged early, the escalation clause that was negotiated before signing, the procurement commitment that was made before prices moved.
If you're planning a project right now, the best thing you can do is start the right conversations before the numbers change again.

FAQ’s
How much have construction material costs increased in 2026? Nonresidential construction input prices surged at a 12.6% annualized rate in just January and February 2026, according to the Associated Builders and Contractors. Since early 2020, fabricated structural metal products have risen over 63% cumulatively. Steel, aluminum, copper, and concrete are the most affected categories right now.
What is a construction escalation clause and do I need one? An escalation clause is contract language that allows material prices to be adjusted up or down based on real commodity index data typically the BLS Producer Price Index if costs exceed a set threshold (usually 3–5% above the baseline). In a market where steel prices fluctuated 47% between Q1 2024 and Q1 2026, any fixed-price contract without one carry real budget risk. If you're starting a project in 2026, you need one.
Which construction materials are most affected by tariffs in 2026? Structural steel, rebar, aluminum storefront and curtain wall, metal deck, copper wire and cable, HVAC equipment housings, and switchgear are the most exposed. Concrete and cement are also under pressure because the U.S. imports roughly 20% of its cement largely from Canada and Mexico and current tariff structures are hitting those supply lines directly.
How can a developer protect their construction budget from rising material costs? The five most effective moves are: engage your GC during pre-construction before design is complete; require transparent line-item pricing on tariff-exposed scopes; negotiate escalation clauses before signing any fixed-price contract; build a 4–6% material escalation contingency into your budget; and work with a GC who has established supplier relationships and can identify material substitutions early.
When should I bring a general contractor into my project? Before design is complete ideally during pre-construction. A GC engaged early can lock in material procurement ahead of price increases, structure bid packages strategically, and build contingencies based on actual market conditions. Owners who bring the GC in at the construction agreement stage inherit whatever the market has done in the interval, with fewer options to respond.
Are construction material costs expected to come down in 2026? The short answer is no not meaningfully. Industry analysts expect volatility to persist rather than resolve. Tariffs, supply chain reconfiguration, labor shortages, and elevated demand across Texas and other high-growth markets are all structural pressures, not temporary ones. Planning for cost stability is the wrong bet right now.
How do I know if my GC is managing material cost risk properly? Ask directly. A GC with a real pre-construction process will be able to walk you through how they track commodity pricing, how they structure procurement commitments ahead of price moves, and how they handle escalation conversations with owners. Vague answers or a GC that leads with the lowest number and figures out procurement later are warning signs.
