UNSPSC 72141109: Viaduct construction and repair service

The building and repair of viaducts owned by others

UNSPSC 72141109 Viaduct construction and repair service (Commodity) encompasses concrete bridge structure rehabilitation, replacement, and related infrastructure work that state and local governments buy to address failing or aging bridge and viaduct assets across jurisdictions. Recent opportunities show work ranging from emergency bridge replacement and seismic compliance retrofits to traffic safety upgrades at existing viaducts. The issuing bodies are predominantly county and city transportation, facilities, and infrastructure departments. Santa Clara County appears as a standout repeat buyer, with multiple seismic compliance projects at healthcare and medical facilities that include non-structural component bracing, equipment anchorage, and related building systems work conducted under state seismic standards. Other recent buyers include Orange County, Florida (bridge replacement); Louisville Metro Government (viaduct safety detection systems); and specialized authorities such as Atlanta Beltline, Inc. and the Central Florida Tourism Oversight District.

Recent activity clusters in California and Florida. In California, Santa Clara County has issued multiple prequalification and design-build RFPs for seismic upgrades to regional medical centers and hospitals, with some projects requiring both design and construction services under California Administrative Code seismic performance standards. In Florida, Orange County solicited emergency bridge replacements (Y26-742, estimated cost $6.2 million; Y26-750 security controls, estimated $7 million) and the Central Florida Tourism Oversight District issued an IFB for erosion repairs at the S-40 Water Control Structure with a mandatory pre-bid meeting scheduled for September 24, 2026, with bids due October 20, 2026. Georgia activity includes trail and corridor construction involving bridge work (Atlanta Beltline, Inc. Northeast Segment 3 and Connector Trails, bids due October 6, 2026) and taxiway exit construction in Arizona (Maricopa County, July 11, 2026). The code shows active procurement across transportation infrastructure rehabilitation, emergency structural repairs, seismic compliance retrofits, and specialized drainage or utility crossing work at bridges and viaducts.
