NIGP 92523: Dam Engineering

NIGP 92523 Dam Engineering is an Item code addressing the specialized design, assessment, rehabilitation, and monitoring services that state and local governments procure for embankment dams, concrete spillways, hydrostatic relief systems, and related water-retention infrastructure. Recent solicitations reveal state and local buyers procuring services across a wide spectrum: structural concrete repair on existing spillway walls, comprehensive hydrostatic relief system assessments and downstream channel improvements, preconstruction management for dam rehabilitation projects under CM/GC delivery, independent cost estimating for alternative delivery programs that include dam projects, and remote monitoring equipment and services for high- and significant-hazard dams. Issuing bodies soliciting under this code include state departments of transportation (Georgia), state natural resources and water agencies (California, Colorado, Utah), county governments (Fayette County and Montgomery County, Maryland), municipalities (Berlin, Connecticut; Griffin and Social Circle, Georgia), and special-purpose water authorities (Brazos River Authority, Texas). The code attracts both major engineering consulting firms and specialized dam engineering contractors with relevant expertise in structural assessment, hydraulic design, permitting coordination, and construction management in remote or environmentally sensitive settings.

Activity concentrates in the Southeast and Mid-Atlantic, with notable recent opportunities in Georgia, Texas, Colorado, and Maryland. Representative recent opportunities include Fayette County, Georgia's ITB 27043-B for structural concrete repairs to Lake McIntosh Dam spillway (bids due November 19, 2026); the Brazos River Authority's RFP for hydrostatic pressure relief system assessment and downstream channel improvements at Sterling C. Robertson Dam (proposals due October 14, 2026); Colorado Parks and Wildlife's CM/GC preconstruction services for Spring Creek Dam Rehabilitation (proposals due June 15, 2026, with construction cost estimated between $8 million and $10 million); the California Department of Water Resources' solicitation for hydrologic engineering expert services (SOQs due July 17, 2026, contract value $50,000 to $100,000); and Carroll County, Maryland's engineering design and permitting services for Piney Run Dam reconstruction (proposals due June 26, 2026). Many recent opportunities emerge from disaster recovery work (Hurricane Helene damage assessments in Georgia) and infrastructure modernization driven by aging infrastructure and regulatory compliance.
