NIGP 95939: Dam and Levee Construction, Maintenance, Management and Repair

NIGP 95939 Dam and Levee Construction, Maintenance, Management and Repair, Item, encompasses water infrastructure protection and remediation work that state and local governments buy to manage flooding risk, restore eroded embankments, repair aging dam structures, and construct new water control systems. Recent solicitations show active procurement across dam rehabilitation, seawall replacement, levee stabilization, flood control ponds, erosion control installation, spillway repairs, and automated gate system upgrades. The work attracts a mix of issuing bodies including county water authorities, cities, state natural resource and parks departments, and special districts; Cherokee County Water & Sewerage Authority in Georgia, Williamson County in Texas, the Illinois Department of Natural Resources, the State of Utah Division of Purchasing, the City of Tarpon Springs in Florida, and the Macon-Bibb County Board of Commissioners represent recent repeat buyers. Scope spans structural replacement (seawalls, spillway gates, stoplog structures), geotechnical remediation (riprap placement, filter fabric, embankment stabilization), mechanical systems (automated gate controls, lift motors), and site restoration. Contracts typically require Georgia utility contractor licensure, Texas prevailing wage compliance, OSHA trench and excavation safety certification, Florida general contractor licensing, or equivalent state-level qualifications; federal funding involvement (NRCS, HUD, FHWA) triggers Davis-Bacon wage requirements and Build America Buy America Act compliance on selected projects.

Geographic activity concentrates in the Southeast and Texas. Georgia leads with recent work at Cherokee County (Etowah River intake modifications, ITB due August 6, 2026), Macon-Bibb County (Lake Tobesofkee automated gate system, ITB due March 26, 2026), and DeKalb County (seawall and recreation infrastructure). Texas shows activity at Williamson County (Smith Branch flood control ponds, IFB due July 21, 2026) and Galveston County (levee and utility relocations). Florida drives consistent volume: City of Tarpon Springs (Craig Park seawall replacement at 3,300 linear feet, IFB due March 6, 2026), City of Altamonte Springs (Little Wekiva River erosion control countermeasures, ITB due March 18, 2026), and City of Palm Bay (four production wells, RFP due April 28, 2026). Illinois (I&M Canal spillway repairs), California (Malibu Creek State Park dam repairs), Utah (Penrose wetland dike maintenance), and Colorado (Big Beaver Dam outlet rehabilitation) round out recent regional activity. Set-asides vary: Illinois mandates 7% Business Enterprise Program and 1% Veterans Business Program participation on Carlyle Lake levee stabilization; California requires 6% DVBE participation minimum at Malibu Creek; Macon-Bibb County encourages M/W/DBE subcontractor participation. Bid securities typically run 5 percent of contract value, performance and payment bonds 100 percent; liquidated damages range from $250 to $2,667 per day depending on project complexity and federal funding involvement. Contract terms vary from immediate (30-day completions on gate systems) to extended (460 working days on landfill cell construction or specialized water well drilling). Most recent procurements post mandatory or non-mandatory pre-bid conferences and site visits; question deadlines typically fall 7–10 days before bid opening.
