UNSPSC 81102200: Transportation engineering

UNSPSC 81102200 Transportation engineering is a Class code encompassing professional services for planning, design, analysis, and support of transportation infrastructure and operations. State and local governments buy detailed engineering studies and design services under this code, including traffic analysis, roadway and signal design, pedestrian and bicycle facility planning, transportation demand modeling, construction engineering and inspection, and specialized transportation operations support. Recent solicitations span red-light camera systems for traffic enforcement, fiber-optic network expansion and middle-mile broadband infrastructure, complete streets and sidewalk planning, traffic signal modernization and maintenance, roadway resurfacing and widening, multimodal trail design, safety action planning, and airport planning and programming. The issuing bodies are diverse and include cities (Orlando, Brownsville, Holyoke, Madison, Atlanta, Stamford, Bristol, St. Petersburg, LaGrange, Dahlonega, Social Circle, Bainbridge, Duluth, Tolleson), counties (Harris, Orange, Montgomery, Columbia, Catoosa, Collier, Sarasota, Bartow), regional authorities and planning organizations (Orange County Transportation Authority, Ocala-Marion County TPO, Cartersville Bartow MPO), state departments (Georgia Department of Transportation, Massachusetts Bay Transportation Authority, Florida Department of Transportation, California High-Speed Rail Authority), and special-purpose districts (Eastern Municipal Water District). Orange County, California and the Georgia Department of Transportation appear as repeat issuers across multiple recent opportunities, establishing qualified vendor lists for various on-call A-E disciplines including roadway and bikeway services, flood control engineering, cost estimating, mechanical and plumbing design support, and land surveying.

Geographic activity clusters in Florida (Orlando, Brownsville, Collier County, Sarasota County, St. Petersburg), Georgia (Atlanta, LaGrange, Dahlonega, Social Circle, Catoosa County, Columbia County, Bartow County), California (Orange County, Brownsville area), and Massachusetts (MBTA), with additional scattered activity in Texas, Arizona, Connecticut, and other states. Representative recent opportunities include the City of Orlando's RFP for a comprehensive red-light camera traffic infraction detector system covering 80 intersections with a proposal deadline of September 17, 2026; the City of Brownsville's design-build procurement for approximately 130 route miles of middle-mile fiber optic network expansion (Rings 7–9) with proposals due August 18, 2026; the City of Holyoke's RFP for preliminary design engineering and surveying for a 1.6-mile Complete Street project along Main Street (Springdale Corridor) with proposals due August 11, 2026; the City of Madison's request for ride-share service providers for the Impaired Driving Reduction Ride Share Project with a $97,240 contract value and proposals due August 19, 2026; the Harris County Toll Road Authority's RFP for a roadside toll collection system with proposals due September 14, 2026; and the Orange County's multiple RFQs for pre-qualified vendor lists across flood control engineering, cost estimating, MEP design support, and land surveying services on a three-year task-order basis with responses due in August and September 2026. The code shows sustained activity across planning, feasibility studies, design phases, and construction support for both capital projects and on-call service vehicles.
