Material prices are rising faster than labor costs
Construction commodity prices rose 13.3% over the past year. Service contractors need tighter quote terms and earlier buying to protect job margins.
The main cost risk on construction work is shifting. Materials and equipment now pose a bigger problem, even as growth in labor costs slows. That can turn a sound estimate into a weak job before the crew arrives.
Construction commodity prices rose 13.3% year over year, according to Contractor Magazine. That increase was more than 4.7 times the rate from one year earlier. Tariffs, limited metals supply, and demand from data centers and infrastructure projects helped drive the rise.
The largest jumps came from common metals. Aluminum rose 40.9%, copper base scrap rose 39.3%, and nonferrous metals rose 38.5%. These increases can reach HVAC, plumbing, electrical, roofing, and remodeling firms through parts, equipment, wire, pipe, and sheet metal.
Labor is no longer the whole cost story
Labor is still tight, mainly in skilled trades. But its cost is rising more slowly than key materials. The ENR Building Cost Index rose 4.7% year over year in August, while its skilled labor part rose 1.5%, according to Contractor Magazine.
Material inflation also appears to be building, not fading. Overall construction materials rose at least 1% month over month for three straight months through August. Annual material price growth moved from 6.5% in June to 8.5% in August.
Contractor prices had risen an average of 4.3% year over year as of June. Concrete pricing rose 6.4%. Cushman & Wakefield expects U.S. construction prices to speed up as higher material and equipment costs move into project prices, according to Contractor Magazine.
Electrical work faces added pressure
Electrical equipment is one clear trouble spot. Electrical machinery and equipment prices rose 13% year over year. Switchgear rose 9%, and transformer and switchgear costs are forecast to rise faster through the end of the year as copper supply stays tight.
Demand is adding to the strain. Grid work, renewable energy projects, infrastructure, and data centers all need electrical gear and specialized labor. Large projects can compete with local contractors for the same products, even when other parts of commercial construction are slow.
Contractors tied to data centers reported an average backlog of 11 months. Those without data center work reported 8.5 months. Infrastructure backlog reached 10.1 months in June, up 7.9% from one year earlier.
The wider commercial market is less steady. Commercial and industrial architectural billings stood at 46.7 in June, below the level that marks growth. Nine of the prior 10 months were below that line, which points to a weak broader pipeline into 2027.
Old estimates can become bad jobs
A contractor cannot assume that a softer market will mean cheaper supplies. A few large sectors are using a heavy share of metals and equipment. That can keep local prices high and lead times long while demand in other sectors remains weak.
This raises the risk on any quote that stays open for weeks or months. A fixed material allowance may be stale by the time a customer signs. A special-order part may also arrive later or cost more than expected, which can hurt both the schedule and the margin.
Owners should separate labor and material assumptions when they review job results. A crew can hit its planned hours and the job can still lose money because equipment or metal costs moved. Looking only at total gross margin can hide the reason.
Purchasing choices matter more in this market. Early procurement can lower exposure on confirmed work, but buying too much can trap cash in stock. Owners need a clear list of fast-moving items, long-lead items, and products with prices that change often.
What an owner can do this week
An owner does not need a new forecasting system to respond. A short review of quotes, supplier terms, and open jobs can find the biggest gaps. The goal is to shorten the time between pricing, approval, and purchase.
- Call key suppliers and ask for current prices and lead times on copper, aluminum, electrical gear, and other high-cost items used on open jobs.
- Add a clear expiration date to new quotes. Reprice material-heavy work when that date passes.
- Review signed jobs that have not started. Buy confirmed long-lead items early when cash and storage allow.
- Track labor and material results separately on completed jobs. Update future estimates where material costs missed the plan.
