Other Heavy and Civil Engineering Construction

The NAICS 237990 category encompasses Other Heavy and Civil Engineering Construction, focusing on large-scale infrastructure development, environmental restoration, and specialized civil engineering projects. These projects typically involve complex construction activities such as dredging, shoreline protection, stream restoration, dam repair, flood control, and transportation infrastructure improvements. The work often requires specialized heavy equipment, advanced engineering techniques, and compliance with rigorous environmental and safety regulations.

Federal Contract Awards under this category demonstrate significant investment in critical infrastructure nationwide. The awards range from $1 million to $500 million, with performance periods typically spanning 180 to 730 calendar days. The U.S. Army Corps of Engineers emerges as the predominant awarding agency, with notable projects including coastal restoration, navigation channel maintenance, dam rehabilitation, and flood control infrastructure. Most contracts are either unrestricted or set aside for small businesses, with a small business size standard of $45 million. Common performance locations include coastal regions, river systems, and military installations across the continental United States, with a particular concentration in Florida, Washington, Louisiana, and Mississippi.

Recent Federal Contract Opportunities within this NAICS category highlight diverse infrastructure improvement projects across multiple federal agencies. The U.S. Army Corps of Engineers dominates the opportunities, soliciting work for projects such as Everglades restoration in Florida, maintenance dredging at naval stations, breakwater repairs in Chicago, and stream stabilization in various states. Other agencies like the Bureau of Land Management, Department of Veterans Affairs, and Department of Agriculture have also posted opportunities for infrastructure improvements. The projects consistently involve complex civil engineering tasks including shoreline protection, stream restoration, dam repairs, pump station construction, and environmental mitigation, with estimated values ranging from $250,000 to $500 million.
