UNSPSC 30121716: Bridge seat mounting

A type of equipment used to distribute the load generated by impact, expansion and contraction that acts on the upper structure of bridge onto the lower structures of the bridge.

UNSPSC 30121716 Bridge seat mounting, a Commodity code, shows minimal relevant recent state and local procurement activity. The code nominally describes hardware and fastening components that secure bridge superstructure to substructure, yet the recent opportunities in the source block are dominated by large-scale bridge construction, replacement, and rehabilitation projects—full bridge design-build work, trail construction, road widening, and utility system repairs—none of which isolate bridge seat mounting as a procurable line item. One Mississippi county solicitation (Coahoma County Board of Supervisors, posting 3170036693, due October 20, 2026) references bridge construction with a pre-bid conference but does not disclose scope detail. A second Mississippi opportunity (Madison County Board of Supervisors, posting 3170035983, due June 25, 2026) solicited the Cauthen Road Bridge Replacement Project and named precast bridge spans and components as pay items but did not parse seat mounting as a separate commodity. The remaining opportunities—Orange County trail and bridge projects, Clayton County bridge rehabilitation (ITB 26-150, due September 16, 2026), Barnwell County utility pipe support repairs, and Okaloosa County precast concrete bridge materials (due April 29, 2026)—bundle multiple bridge subsystems under single contracts rather than isolating fastening hardware. Fort Bend County, Texas posted a term contract notice for bridge materials (ITB B27006, due September 8, 2026) without specification attachments.

State and local governments are actively soliciting bridge work across Georgia, Florida, Mississippi, South Carolina, and Texas, but they are not breaking out bridge seat mounting as a discrete procurement category. The activity is concentrated among county and city transportation departments and regional trail authorities in the Southeast and Texas. Contractors in this commodity should monitor large bridge construction and rehabilitation ITBs and RFPs for subsystem component awards or supply-chain roles within broader projects, as standalone bridge seat mounting solicitations do not appear in recent state and local notices.
