UNSPSC 72141203: Dam construction service

The building of dams owned by others

UNSPSC 72141203 Dam construction service is a Commodity code encompassing the repair, rehabilitation, and construction of dams and associated intake structures, water control systems, and embankment stabilization work solicited across state water agencies, county water authorities, municipal utilities, and regional water management districts. State and local governments buy under this code to address aging infrastructure, emergency repairs from weather events, dam safety compliance, flood control capacity upgrades, and water intake modifications. Work ranges from replacement of spillway components and outlet control structures to comprehensive embankment reconstruction, automated gate system upgrades, and riprap placement for erosion control and structural integrity. The issuing bodies include water authorities (Cherokee County Water & Sewerage Authority in Georgia, City of Palm Bay in Florida), municipal utilities (Norwich Public Utilities in Connecticut), county governments (Macon-Bibb County in Georgia, Williamson County in Texas, Galveston County in Texas), state departments and divisions (Colorado Parks and Wildlife, Illinois Department of Natural Resources, Florida Department of Environmental Protection), and regional entities (Georgia World Congress Center Authority). Recent activity shows significant repeat procurement from Connecticut municipalities and Georgia jurisdictions.

Geographic concentration spans the Southeast and Midwest, with strong recent activity in Georgia (multiple dam gate, intake, and reservoir projects), Connecticut (Broad Brook Reservoir Dam, Plants Dam, Greenville Dam), Florida (production wells, canal plugging, seawall and erosion control), Texas (Smith Branch flood control ponds, utility relocations for levee improvements), Illinois (I&M Canal spillway repairs, Carlyle Lake embankment stabilization), and Colorado (Big Beaver Dam, Lake Christine). Representative recent opportunities include the Cherokee County Water & Sewerage Authority's Etowah River intake modifications IFB with bids due August 6, 2026, requiring Georgia-licensed utility contractors and involving raw water intake piping extension, passive intake screens, and riverbank stabilization; Williamson County's Smith Branch Flood Control and Water Quality Ponds IFB with response deadline July 21, 2026, for FEMA levee and floodwall construction; and the Macon-Bibb County automated gate system upgrade design-build procurement (Bid 26-038-LH) with sealed bids due March 26, 2026, scored on experience, approach, timeline, and price. The code also reflects substantial federal co-funding through HUD grants (Craig Park seawall in Tarpon Springs at $2 million), NRCS emergency watershed protection funding (Altamonte Springs erosion control), and state environmental finance authority grants (Cornelia raw water reservoir improvements).
