NIGP 92503: Aeronautical/Aerospace Engineering

NIGP 92503 Aeronautical/Aerospace Engineering, an Item code, encompasses professional design, engineering, planning, and construction administration services for airport infrastructure, facilities, and airfield systems. State and local governments procure comprehensive A-E services under this code for terminal expansions, runway improvements, taxiway rehabilitation, pavement projects, parking facilities, environmental assessments, feasibility studies, and specialized systems including power generation, green infrastructure, and renewable energy integration at regional airports, municipal facilities, and public-sector aviation assets.

The issuing bodies soliciting under this code include county public works departments (particularly the County of Orange, California, which dominates the recent activity), regional airport authorities, city aviation departments, and standalone airport management entities across California, Georgia, Florida, Texas, Utah, Maryland, and New Mexico. The County of Orange Public Works Department and Orange County Flood Control District have issued at least ten separate RFQs since mid-April 2026 establishing Qualified Vendor Lists for specialized A-E disciplines including land surveying, flood control engineering, cost estimating, mechanical/electrical/plumbing design, geotechnical services, power generation, green infrastructure, materials testing, and project management on task-order basis. Representative recent opportunities include the County of Orange's RFQ for Land Surveying Services (RFQ0803060401MG, responses due July 21, 2026) and Flood Control Engineering Services (RFQ0803091002RE, due August 13, 2026), both task-order contracts with three-year terms and no guaranteed minimum work volume; the City of Santa Fe's qualification-based RFP for Santa Fe Regional Airport Terminal Expansion A-E Services (FY26RFP035, due December 17, 2025); and multiple Georgia airport consulting procurements including Ware County's RFQ for Waycross-Ware County Airport (PE77150NONST2027000000027, due July 27, 2026) and the City of Thomson's five-year Master Agreement RFQ for Thomson-McDuffie County Regional Airport engineering and construction services (PE69754NONST2026000000016, due May 1, 2026). Evaluation typically employs weighted scoring on qualifications and experience (40 percent), key personnel and staffing (17.5–20 percent), availability to perform services (25 percent), and SOQ organization and compliance (12.5–15 percent). Compensation is universally structured as time-and-materials with hourly classification rates negotiated after award, no price increases permitted during the contract term, and prevailing wage compliance required where applicable. Insurance minimums commonly include $1–3 million commercial general liability, $1–2 million professional liability, and workers' compensation at statutory levels, with the issuing body named as additional insured.
