UNSPSC 81101507: Dam engineering

UNSPSC 81101507 Dam engineering is a Commodity code that encompasses design, rehabilitation, permitting, inspection, and construction management services for earthen dams, concrete dams, spillways, and related hydraulic structures. State and local governments procure under this code when addressing dam safety deficiencies, seepage control, spillway upgrades, automated gate systems, and comprehensive rehabilitation of aging or hazard-classified facilities. The issuing bodies include state natural-resources and water-management agencies (California Department of Water Resources, Colorado Parks and Wildlife, Georgia Department of Transportation, Rhode Island Department of Environmental Management), county governments (Montgomery County Maryland, Macon-Bibb County Georgia, Madison County Georgia, Collier County Florida, Harris County Texas), city utilities and public works departments (Salt Lake City, Dallas Water Utilities, City of Madison Connecticut), and special-purpose districts (St. Johns River Water Management District, Riverbend Water Resources District). Recent opportunities show state and local governments actively procuring pre-construction CM/GC services, alternatives analysis, design-build and final design packages, hydrologic engineering reviews, construction engineering and inspection, automated monitoring systems, and post-construction repairs—typically through RFP, RFQ, and IFB processes with response dates ranging from March through August 2026.

Geographic activity concentrates in the Southeast (Georgia, Florida, South Carolina, Connecticut), Western states (Colorado, Utah, California), and Texas, with standout repeat activity in Georgia (GDOT, Macon-Bibb, Madison County) and California (DWR). Representative recent solicitations include the Town of Madison's RFP for the Neck River Flood Water Diversion System rehabilitation engineering design (RFP, due August 12, 2026); Colorado Parks and Wildlife's CM/GC preconstruction services for Spring Creek Dam Rehabilitation in the Grand Mesa, Uncompahgre, and Gunnison National Forest (RFP, due June 15, 2026; preconstruction phase $130,000 to $150,000, construction fixed limit $8 million to $10 million); the Rhode Island Department of Environmental Management's qualification-based-selection procurement for the Barberville Dam alternatives analysis (due July 21, 2026; 10% MBE/WBE participation required); the California Department of Water Resources Division of Safety of Dams hydrologic engineering expert panel review ($50,000 to $100,000, contract September 2026 through September 2029); and the Salt Lake City Department of Public Utilities' engineering services for Red Pine Dam rehabilitation (due March 27, 2026; High Hazard Potential Dams grant funding anticipated). Prevailing wage, Build America Buy America Act compliance, and Section 3 requirements appear frequently in federally funded projects; insurance minimums typically range from $1 million to $3 million in professional liability and general liability.
