UNSPSC 81101511: Railway engineering

UNSPSC 81101511 Railway engineering is a Commodity code that encompasses design, engineering, and specialized technical services supporting rail infrastructure projects, including signal system design and installation, dispatch network optimization, cost estimating for rail capital programs, and construction oversight on rail transit and freight railway assets. State and local buyers—primarily state departments of transportation, transit authorities, and regional railway authorities—procure these services to advance freight rail rehabilitation, commuter and light rail modernization, and P3-funded transit infrastructure initiatives.

Recent activity spans Georgia, Connecticut, Florida, Mississippi, New Jersey, and California. The Georgia Department of Transportation is actively soliciting independent cost estimating services (RFQ PE48401RFQ2027000000629, due November 16, 2026) and general engineering consulting for the I-75 South Express Lanes project (RFQ PE48401RFQ2027000000616, due August 24, 2026). The Connecticut Department of Transportation is procuring pre-wired signal equipment and design for the New Haven Line from Norwalk to Bridgeport (RFP 26-CTRAIL-SIGNALS-1, proposals due November 5, 2026), requiring vital microprocessor-based wayside signal architecture, fiber optic networks, and compliance with 49 CFR Part 236 and AREMA standards. The South Florida Regional Transportation Authority released an RFP (26-011, due November 3, 2026) for dispatch network redesign assessment and enterprise network configuration spanning six data centers and forty-nine wayside locations, with Davis-Bacon prevailing wage and Buy America compliance. The Itawamba County Railroad Authority in Mississippi issued an IFB (due September 15, 2026) for railway washout repair at Beans Ferry. The New Jersey Transit Rail Operations authority is procuring light rail state safety oversight support services (T3054, due June 12, 2026), and the California High-Speed Rail Authority is soliciting collaborative design-build services for the Merced to Madera Civil Works Project (RFQ HSR26-16, due November 30, 2026), a 30.3-mile guideway with mandatory 25% small business participation and 10% DBE goals. Representative work ranges from signal and dispatch system modernization on urban transit corridors to multi-phase capital delivery on freight and high-speed rail, with most opportunities requiring federal compliance frameworks (FTA, FEMA, or FAA), cost-plus-fixed-fee or lump-sum pricing, performance and warranty bonds, and demonstrated experience on similar rail or transit projects of significant scope and complexity.
