NIGP 92528: Drainage Engineering

NIGP 92528 Drainage Engineering, an Item code, encompasses design, engineering, and construction services for stormwater conveyance, flood mitigation, and drainage system improvements that state and local governments procure to address recurring flooding, aging infrastructure, and water-quality compliance across residential neighborhoods, transportation corridors, and mixed-use districts. Recent solicitations show state and local agencies buying detailed design work at multiple completion stages, permitting and environmental review services, construction engineering and inspection, and independent cost estimation for complex drainage projects, often paired with green infrastructure, resilience assessments, and multi-modal transportation integration where work intersects roadway or utility systems.

Issuing bodies across the code span county commissions (Pinellas, Collier, Greenville, Harrison, Whitfield, Williamson), municipalities (Fort Myers, Orlando, Bend, North Miami Beach, Statesboro, Peachtree Corners, Dallas, Mableton), state departments (Georgia DOT, Texas), university systems (Texas A&M, Sam Houston State), regional authorities (Greater Orlando Aviation Authority, San Antonio River Authority), and special districts (West Basin Municipal Water District, Clackamas County Water Environment Services). Texas, Florida, Georgia, and Oregon see the most recent activity, with additional work in Colorado, South Carolina, and Mississippi. The Town of Parker, Colorado issued RFQ 26027 (due November 14, 2026) for a three-phase engineering contract covering design and construction documents for Chambers Road drainage and bridge work; Greenville County, South Carolina posted IFB 27023 (due October 21, 2026) for storm drainage installation totaling 405 linear feet of pipe and four inlet structures on Suffolk Drive; the City of Fort Myers issued RSQ 26-031 (due October 28, 2026) for closed drainage design replacing Carrell Canal with a permanent pumping station and multi-use path, incorporating local vendor preference scoring and MBE compliance points; and the City of Orlando solicited RQS26-0612 (due October 14, 2026) for design and oversight of drainwell replacement and relocation across 13 sites, funded through CDBG-DR and subject to federal Davis-Bacon and debarment requirements. The Georgia Department of Transportation issued concurrent RFQs for Independent Cost Estimator services supporting P3 and Design-Build projects (due November 16, 2026 under solicitation PE48401RFQ2027000000632) and on-call roadway design services statewide. Project budgets range from under $1 million for focused improvements to $17.4 million for comprehensive drainage and water-quality restoration, with most design contracts negotiated under Consultants' Competitive Negotiation Act frameworks and evaluation weighted toward experience, past performance, and team qualifications rather than lowest price.
