NIGP 92550: Hydroelectric Engineering

NIGP 92550 Hydroelectric Engineering, an Item code, encompasses professional engineering services state and local governments procure to design, assess, and oversee improvements to hydroelectric facilities, water treatment plants, dams, and related water infrastructure systems. Recent solicitations show the code covers design and permitting for emergency power systems at water treatment plants, structural and hydrologic assessment of high-hazard dams, construction management at risk (CMAR) for potable water treatment facilities addressing contamination, and related engineering consulting for water supply and stormwater infrastructure. The issuing bodies include water authorities (the Brazos River Authority in Texas), municipal utilities (Sarasota County, Florida and the City of Tucson, Arizona), county governments, and state transportation and infrastructure departments. State agencies such as the Georgia Department of Transportation (GDOT) and specialized water and regional authorities drive significant activity under the code through on-call general engineering consulting contracts for infrastructure and alternative delivery programs.

Recent opportunities span Florida, Arizona, Texas, and Georgia, with GDOT consistently posting multiple concurrent procurements for on-call general engineering consulting services supporting transportation and water infrastructure projects. Representative recent solicitations include Sarasota County's RFP 262903FB for engineering design and permitting of backup power systems at the Carlton Water Treatment Plant (due October 15, 2026), the City of Tucson's RFQ 260101 for a CMAR to design and construct the Northwest Well Treatment Facility addressing PFAS and 1,4-dioxane contamination at a $33 million estimated cost (proposals due September 11, 2025), and the Brazos River Authority's RFP for comprehensive engineering assessment and design of hydrostatic pressure relief systems and downstream improvements at Sterling C. Robertson Dam near Waco, Texas (due October 14, 2026). GDOT has issued multiple concurrent RFQs for general engineering consulting services in designated regions under on-call, indefinite-quantity contracts with minimums of $25,000 and maximums of $25 million over five-year terms, with two-phase qualification-based selection processes and scoring weighted toward project manager experience, past performance, and technical approach in alternative delivery environments.
