Industry Summary

The 39,200 site preparation contractors in the US prepare land for construction activity. Services include excavation work; wrecking and demolition; trenching; sewer and water main installation; construction machinery rental (with operator); and road construction. While private sector projects account for the majority of revenue, site prep contractors also provide services to federal, state, and local governments.

Dependence On General Contractors

Because site preparation is just part of the construction process, companies often depend on general contractors to secure client business.

Seasonal And Weather-Related Factors

Seasonality and weather conditions affect project timelines and site prep contractors’ ability to perform work.


Recent Developments

Dec 10, 2025 - Megaprojects Boost Construction Starts
  • Megaprojects drove substantial gains for the total value of construction starts in October compared to September, according to Dodge Construction Network. Nonbuilding construction starts jumped 59.4% in October, led by a 384.5% surge in utilities and an 18.6% rise in environmental public works. Highway and bridge starts were down 23.7%. Nonresidential building construction starts increased 17.9% in October compared to the previous month, amid a 19.5% rise in commercial starts, led by data centers (+45.5%) and retail stores (+15.1%). Institutional starts grew 3.7% due to project categories other than education and healthcare, which saw starts fall 20.8% and 2.7%, respectively. Residential starts dropped 15.4% in October, with single-family starts down 2.2% and multifamily starts down 38.5%. Dodge said 10 projects valued at $1 billion or more broke ground in October, primarily in data centers, manufacturing, and liquefied natural gas (LNG) facilities.
  • Construction firms that work on civil infrastructure projects are holding steady as they manage uncertainties, including waning backlog growth and stagnant margins, according to FMI’s fourth-quarter Civil Infrastructure Construction Index (CICI) survey. The CICI reading for the third quarter was 50.6 compared to 50.8 in Q3 2025 – on a 100-point scale. Any CICI reading above 50 indicates that more civil infrastructure contractors see conditions as good than poor. About half of civil infrastructure contractors reported that their backlogs in Q4 met or exceeded their targets. However, most noted that public projects are making up a growing share of overall backlogs, as private-sector projects face greater uncertainty. Contractors expect backlog growth to slow over the next few quarters as more firms vie for a narrower set of public projects. Contractor margins remained steady but flat in Q4 2025 as bid competition and rising cost pressures eroded pricing power.
  • The 43-day federal shutdown, the longest in U.S. history, ended November 12, but construction industry disruptions persist, according to Engineering News-Record. Infrastructure agencies, including the Department of Transportation, the Environmental Protection Agency, and the Army Corps of Engineers, remain under a continuing resolution through January 30, 2026, which limits spending, staffing, and new program starts. Contractors are facing mounting delays in grant agreements, environmental reviews, and permit approvals, particularly for transportation, water, and civil works projects. Inflation and seasonal timing compound risks, as procurement delays may drive up material costs. Public owners must still meet Infrastructure Investment and Jobs Act deadlines despite slowed federal processing. The reopening offers a path forward, but recovery will be gradual, requiring strategic planning across the construction sector to manage uncertainty and maintain momentum.
  • President Trump’s tariffs and immigration crackdown are straining US homebuilders, raising costs and worsening labor shortages, according to The New York Times. Builders face higher prices for steel, copper, lumber and other materials, with tariffs adding up to $10,900 to the cost of a typical home, according to the National Association of Home Builders. Immigration enforcement has made workers fearful, delaying projects and shrinking crews. Construction added only 6,000 jobs through August, despite an Associated Builders and Contractors projection that nearly 500,000 more workers will be needed in 2026. Builders are slowing activity, cutting budgets and bracing for slower growth as high mortgage rates and weak demand are dragging down sales. Economists warn that even if interest rates fall, labor and material pressures could intensify.
