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.

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


Recent Developments

May 9, 2025 - Home Builders Boost Incentives to Lure Wary Buyers
  • US home builders are dangling more incentives to close deals amid a tepid spring home-buying season that is halfway over, according to The Wall Street Journal. Builders typically notch 40% of their annual sales during the spring, but mortgage rates that are stuck around 7% and a lack of affordability have reduced demand. Builders have increased incentives to bring buyers off the sidelines, including mortgage-rate buydowns, design upgrades, and price cuts. In the first two weeks of April, incentives offered by builders equaled 7.2% of the purchase price, up from 6.1% in January, according to data from John Burns Research & Consulting. Incentives are eating into builder profits during a season that usually sees few discounts, and prices tend to rise. Soft demand for new homes is expected to worsen as the effects of tariffs take hold, potentially adding between $5,000 and $15,000 to the cost of a new home.
  • Demand for building design services declined in March compared to February, according to an April report by the American Institute of Architects (AIA). The AIA’s Architecture Billing Index (ABI) fell to 41.1 in March compared to February’s reading of 45.5. Any reading of 50 or more indicates growth in architectural billings. The score for new project inquiries fell to 47.7 in March compared to 47.8 in February, but the index for the value of new design contracts increased from 42 to 42.4. The AIA’s Chief Economist, Kermit Baker said, “Clients are increasingly cautious about starting projects due to uncertainty over future trends in interest rates and building materials costs, as well as the potential for an economic slowdown. Unfortunately, this softness in firm billings is likely to continue as indicators of future work remain weak, however, the average project backlog at firms stands at a reasonably healthy 6.5 months, offering a bit of a buffer if future project work continues to remain soft.”
  • The total value of construction put in place decreased 0.5% in March compared to February, according to the US Census Bureau. Spending on nonresidential projects fell 0.5%, and residential spending declined by 0.4%. Within the nonresidential segment, 11 of 18 construction subcategories saw spending decline, including healthcare (down 1.8%), lodging (-1.3%), office (-1.2%), commercial (-1%), and educational (-0.8%). Spending was also weaker for power, highway and street, sewage and waste disposal, manufacturing, and communication. Pockets of nonresidential building spending growth included transportation (up 1.2%), public safety (+0.7%), and amusement and recreation (+0.1%). Associated Builders and Contractors Chief Economist Anirban Basu said, “Data center investments, which accounted for more than 70% of the increase in private nonresidential construction spending between March 2024 and March 2025, are perhaps the only remaining source of industry momentum. Manufacturing construction, while still elevated, has wavered in recent months. Most commercial segments remain subdued under the weight of high borrowing costs and tight lending standards. Residential construction continues to slide.”
  • The price gap between new and existing homes is narrowing, according to National Association of Home Builders analysis of US Census Bureau data. In the first quarter of 2025, the median price for a new home was $416,900, only $14,600 more than the median existing home price. In Q1, the median price for a new home declined 2.32% year-over-year; the median price for an existing home rose 3.38% over the same period. The average price difference between new and existing homes over the last five years is $26,700 and over 10 years it’s $66,000. The price gap between new and existing homes has been closing as tight inventories of existing homes have pushed up prices. At the same time, builders have reduced lot and home sizes and offered incentives to attract buyers.
