UNSPSC 81101510: Highway engineering

UNSPSC 81101510 Highway engineering is a Commodity code capturing the full range of design, planning, and engineering services that state and local governments solicit to support roadway, pedestrian, and multimodal transportation infrastructure projects. Recent opportunities show state and local buyers sourcing preliminary and final design services, construction engineering and inspection, traffic and transportation planning, cost estimation, environmental documentation, permitting support, and site surveys for projects spanning rural county roads, urban corridors, interstate grade separations, bicycle and pedestrian facilities, and specialized transportation initiatives funded by federal, state, and local sources.

State and local issuing bodies active under this code include county departments of transportation and public works, city engineering divisions, transit authorities, and special-purpose airport authorities across the Southeast, Midwest, Southwest, and West Coast. The Georgia Department of Transportation appears as a standout repeat buyer, posting multiple RFQs and RFPs for alternative delivery program support, intelligent transportation systems, and design-build cost estimation. Other frequent issuers include Collier County (Florida), San Mateo County (California), cities in Texas, and municipalities in Arizona, Connecticut, Wisconsin, and Oregon. Representative recent opportunities include the Georgia Department of Transportation's RFQ for Independent Cost Estimator services supporting the I-285 East Express Lanes Project (due November 16, 2026, RFQ PE48401RFQ2027000000632); San Mateo County's on-call engineering and professional services RFP covering multiple disciplines including traffic engineering and pavement condition inspection (due August 21, 2026, RFP RU403); and the City of Lewisville, Texas RFQ for a Comprehensive Safety Action Plan under the FY2024 Safe Streets and Roads for All Planning Grant (due November 2, 2026, RFQ 2701Q). Activity clusters heavily in Georgia and Florida, with substantial secondary activity in California, Texas, Arizona, Connecticut, Wisconsin, Oregon, Illinois, and New Mexico. The code shows continuous procurement velocity across design, preconstruction, construction administration, and specialized planning studies, with contract values ranging from under $500,000 for design concept reports to multi-million-dollar, multi-phase agreements and on-call master service agreements spanning three to five years.
