NIGP 92528: Drainage Engineering

NIGP 92528 Drainage Engineering, an Item code, encompasses the planning, design, and engineering services that state and local governments procure to develop stormwater systems, flood mitigation infrastructure, and roadside drainage improvements. Recent solicitations show municipalities and water districts buying detailed design packages, construction plans and specifications, hydraulic modeling, geotechnical studies, permitting coordination, and construction-phase inspection services for stormwater conveyance, detention and retention ponds, culvert rehabilitation, underdrain systems, and integrated flood-resilience projects. The work ranges from small local drainage modifications and pond maintenance studies to large-scale corridor improvements and regional water-management initiatives.

State and local buyers under this code span city public works departments (Dallas, Pembroke Pines, Union City, Alpharetta, Sandy Springs), county boards and utility districts (Orange County Florida, Collier County, Seminole County, Galveston County, Madison County, Beaufort County, Clay County, Pinellas County), special-purpose water authorities (West Basin Municipal Water District), and state departments (GDOT, Texas A&M System). Florida counties, particularly Orange County and Collier County, appear as repeat solicitors. Representative recent opportunities include the City of Dallas's request for stormwater and flood protection engineering services (RFP, responses due August 21, 2026); West Basin Municipal Water District's on-call professional engineering services for water and wastewater infrastructure across multiple disciplines, with up to five firms awarded through June 30, 2029 and an estimated total value of approximately $3,000,000 (RFP, responses due July 14, 2026); Orange County Florida's underdrain installation and repair services across unincorporated areas, estimated at $3.921720 million for one year and $19.608120 million for five years (IFB, bids due August 4, 2026); and Collier County's construction engineering and inspection services for the Pine Ridge Road Corridor Improvements (RFP, responses due August 5, 2026). Geographic activity concentrates in Florida (particularly Central and Southeast), Georgia, and Texas, with additional recent solicitations in California, South Carolina, Oregon, and New Mexico. The code shows steady demand from municipalities managing aging stormwater infrastructure, implementing post-disaster resilience projects funded through CDBG-DR and state emergency programs, and pursuing federal and state grant-funded water system improvements. SBE and MBE preferences appear in several jurisdictions' evaluation criteria, and prevailing wage compliance is routine for federally funded work.
