Industry Summary
The 3,900 structural steel and precast concrete contractors in the US erect, assemble, and install structural elements of buildings. Large firms may offer design/build services or fabrication services. Firms may also offer repair or restoration services.
Hazardous Work
Structural iron and steel work is one of the top 10 most hazardous occupations in the US, as the incidence of injury and illness for structural steel and precast concrete contractors was 40% higher than the national average in 2023.
Dependence on Nonresidential Construction Activity
Demand for structural steel, reinforcing steel, and precast concrete is primarily dependent on nonresidential construction activity, which can be cyclical and influenced by economic conditions.
Nonresidential Construction Spending Drops
Nonresidential construction spending has slowed amid mounting challenges, including inflation and higher interest rates.
Recent Developments
Jul 7, 2026 - Construction Industry Confidence Holds Steady in Q2
- Construction industry confidence held steady in the second quarter, with Engineering News-Record's (ENR) Construction Industry Confidence Index remaining at 54 and its Economic Index staying at 48 for a third consecutive quarter. Index readings of 50 or more suggest a healthy industry. Executives reported weaker views of the current market but slightly improved expectations for the next 12 to 18 months. General contractors and construction managers were the most confident, while design firms improved and subcontractors slipped. Larger firms remained more optimistic than smaller ones. More than 75% of ENR respondents reported upward price pressure. Industry watchers suggest inflation, higher rate expectations, and materials costs are weighing on contractors, though strong demand, especially for data centers, continues to support the market.
- The total value of US construction put in place rose 0.1% in May 2026 compared to the prior month, according to the US Census Bureau. In the nonresidential buildings segment, growth was led by amusement and recreation manufacturing, which grew 0.9%, while overall investment in private nonresidential structures declined 0.3% in May from April. Spending on healthcare and educational projects each rose by 0.3% in May, while office spending increased by 0.2%. Construction spending on commercial projects fell 0.3%, and lodging spending fell 0.2%.
- Facilities Dive reports that modular data center design and construction could help developers ease bottlenecks tied to labor availability, land constraints, permitting, and long lead times for power and electrical equipment. Data center infrastructure firm Flex says modular construction can reduce on-site testing and cabling by 70% and shorten overall project timelines by 30%. The approach moves more work into controlled factory settings, which can support earlier procurement, more consistent equipment performance, and safer worksites. The shift is gaining attention, as 60% of data center projects expected to be online in 2027 have not started construction, according to JPMorgan analysts. Partly due to permitting issues, at least 20 projects worth nearly $42 billion were canceled in the first quarter of 2026, according to Heatmap. Modular power, cooling, and IT systems also may help operators adapt as chip technology and power requirements change.
- Demand for building design services declined in May 2026 over the prior month, as architectural billings remain soft, according to a June report by the American Institute of Architects (AIA). The AIA’s Architecture Billing Index (ABI) fell to 44.5 in May from April's reading of 48.3. Any reading of 50 or more indicates growth in architectural billings. The score for new project inquiries fell to 49.4 in May, down from 57.7 in April, and the index for the value of new design contracts decreased from 48.0 to 45.0. The AIA’s Chief Economist, Richard Branch said, "The uncertainty created by the Iran conflict, and substantially higher energy costs, weighed on architect billings in May. Higher interest rates, rapidly rising material costs, and continued labor shortages all contributed to softer demand."
