Construction material prices in 2026 are rising faster than most Carolinas contractors are adjusting their bids. The danger is not only higher material costs, but stale assumptions moving into fixed-price and GMP contracts.
For Carolinas commercial and industrial construction, 2026 is no longer a normal escalation year. National input-price indices, regional supplier feedback, and buyout experience point to construction material prices rising roughly 7.0% year-over-year through April, with 6.2% of that rise coming in the first four months.
That compares with only about 4.8% cumulative construction material cost inflation across the prior three years. Published Producer Price Index data from the Bureau of Labor Statistics and industry reports show a broad baseline escalation of 4% to 6%, while specific sectors face annualized surges above 12%.
The fastest-moving material categories include:
Not all materials are moving together; material price volatility has become highly category-specific, with different materials following their own pricing patterns rather than broad market trends.
On actual Carolinas projects, site packages, tilt-wall warehouses, hospital work, higher-ed jobs, and manufacturing facilities are seeing 5–10% buyout gaps when quotes expire. Owners still want aggressive prices, but suppliers are already repricing for 2026 risk.
Last year felt volatile, but 2026 has brought a different order of magnitude of pressure on construction material costs. Previously manageable single-digit inflation has given way to compounding cost shocks in Q1 and Q2, especially for steel- and energy-intensive construction materials.
Pricing cycles have shortened again. Some suppliers now reprice monthly or biweekly, while the validity of quotes has narrowed from 30–60 days to 7–15 days. That directly affects how long contractors can stand behind bids.
Smaller and mid-sized construction companies across the Carolinas feel this most sharply because they have less leverage than national firms to negotiate inventory buffers, long-term supply agreements, or preferred supplier terms, making ABC Carolinas membership and peer networks a valuable way to narrow the gap.
Construction materials prices in 2026 are being pulled higher by three forces: energy and oil markets, tariff impacts on metals, and elevated interest rates. This is not generic inflation; it is concentrated upward pressure in the construction material categories that matter most for nonresidential construction.
Uncertainty around the Strait of Hormuz and broader Middle East tensions have kept oil prices volatile. Manufacturing construction inputs is energy-intensive, with crude oil prices nearing $100 per barrel and a 30% spike in natural gas prices making concrete kiln operations more expensive.
Ongoing geopolitical tensions can spike oil and natural gas prices, increasing the cost of manufacturing energy-intensive materials and raising freight charges. The following materials are especially affected:
Transportation costs are rising as fuel surcharges return to haul and freight invoices. Estimators should assume higher freight components on:
Tariffs, trade restrictions, and geopolitical instability are increasingly driving volatility in construction material prices in 2026 by disrupting supply flows and raising input costs across the supply chain. Tariffs, trade restrictions, and geopolitical instability are also raising input costs at multiple points in the supply chain.
Steel prices are projected to rise by 15–35% in 2026, influenced by tariffs and ongoing trade policy issues, despite some stabilization compared with previous years. Imported steel and aluminum are expected to see 15–25% increases due to tariffs and unpredictable policy changes.
Many Carolinas contractors are seeing steel mill product quotes 10–20% higher than a year ago. Copper prices are expected to increase by 25–50% due to electrical work, infrastructure projects, and tight supply. The following materials remain exposed:
Geopolitical tensions around the Strait of Hormuz increase risk premiums, insurance costs, and transit times for energy and raw materials. Even domestic Carolinas projects are affected because global commodity benchmarks influence local material prices.
Recent global tariffs and trade tensions are straining the global supply chain, particularly for energy-intensive and imported materials, leading to increased transportation costs and extended delivery timelines. The following items need longer procurement buffers:
As of mid-2026, rate cuts look less likely, and markets are pricing the possibility of more rate hikes before year-end. Higher interest rates raise the cost of:
Some clients delay or re-phase projects, while others push to lock in construction costs now. That leaves contractors carrying more risk to keep the backlog full. Thin margins and higher financing costs can turn a manageable overrun into a loss of profit margin.
Construction material prices are rising faster than bid prices, creating a margin gap that shows up late in buyout. Many owners and construction managers still rely on 2024–2025 assumptions, while suppliers price for 2026 realities.
Most contractors know the temptation: under-escalate material costs to win the work, then hope productivity or change orders recover the money. That strategy is dangerous in fixed-price and GMP work.
A 5–7% steel surprise on a distribution center, or a similar asphalt increase on a K–12 school site package, can erase projected profitability. In this market, contingency planning is not optional.
The ABC Construction Backlog Indicator hit a ten-month high in April 2026, signaling that construction activity and demand remain strong. But the gain is concentrated among the largest contractors.
Large firms are active in:
Specialized sectors, notably data centers, are seeing hyper-growth, with a 7% increase in construction starts driven by demand for heavy electrical machinery and structural steel.
Labor statistics also matter. The construction industry requires approximately 499,000 new workers to meet backlog demands, contributing to high labor wages and affecting material costs. Labor shortages amplify construction material costs, increasing total project costs and making material increases more impactful in fixed-price contracts.
When skilled labor is scarce:
Unemployment is not a direct cause of higher material cost, but it constrains supply, production, and project throughput.
This is the checklist section for estimators, executives, and procurement leads. ABC Carolinas supports members through education, advocacy, networking, and peer insights to help manage ongoing cost pressures.
ABC Carolinas is a regional construction trade association helping commercial contractors in North and South Carolina manage fast-changing market conditions, including construction material prices, through chapter leadership and member collaboration.
Our advocacy work and member-led committees give members a voice on:
Our education programs cover:
Networking events and peer roundtables help companies compare supplier practices, current material prices, and margin-protection strategies in real time, with construction safety, networking, and educational events giving members frequent touchpoints across the Carolinas. In a market defined by uncertainty, disciplined business practices are a competitive advantage.
For volatile construction materials such as steel, asphalt, and copper, as well as imported MEP equipment, refresh supplier quotes every 2–4 weeks during active bidding. Monthly may work for shorter or less material-intensive projects, but anything longer than 6–9 months should assume at least one major repricing cycle.
Acceptance varies by owner type, but many public, institutional, and private owners are more open to narrow clauses tied to steel, asphalt, fuel, or other defined indices. Private developers may prefer caps, shared-risk structures, or shared savings if prices fall.
Elevated interest rates mean contractors should stock only materials for which expected price increases outweigh financing and storage costs. Run a simple comparison between carrying inventory for 3–6 months and the likely rise in material prices.
No. Large companies may have more supplier leverage, but smaller firms can narrow the gap through local supplier relationships, group purchasing, clean purchasing controls, and reduced waste. ABC Carolinas membership can also strengthen advocacy, education, and peer connections.
Watch U.S. trade policy on iron and steel, Federal Reserve interest-rate signals, oil supply routes such as the Strait of Hormuz, and local permitting trends in Charlotte, Raleigh–Durham, Greenville–Spartanburg, and Charleston. Lumber prices may increase by 20–40% in 2026 due to supply constraints and rising housing demand, so residential demand can still affect commercial materials.
