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, captures the fabrication and installation of specialized structural components that support bridge decks on substructure elements. State and local governments procure bridge seats as integral components within larger bridge construction and replacement projects, typically bundled with concrete piles, deck systems, and related structural work rather than as standalone products. Recent solicitations show procurement spanning multiple issuing bodies—counties, cities, and regional authorities in Florida, Mississippi, Georgia, Texas, and Washington—with activity concentrated in bridge new construction, replacement, and pedestrian infrastructure projects that require prestressed concrete or steel truss systems with associated seating and bearing hardware.

Orange County, Florida emerges as a repeat buyer, with multiple active solicitations including the Horizon West Trail - Phase 1A (IFB Y26754, due August 13, 2026, $5.657 million), featuring 838 linear feet of prestressed concrete pile-supported boardwalk with precast reinforced concrete deck components requiring PCI or NPCA certification; the Emergency Wallington Drive and Egret Way Bridge Replacements (IFB Y26742, due July 7, 2026, $6.202 million); and the International Drive and Sand Lake Road Pedestrian Bridge (RFP Y26806, due May 7, 2026, $4.4 million design services). Okaloosa County, Florida is procuring precast prestressed concrete bridge materials for the Bone Creek Bridge (ITB ITBPW4026, due April 29, 2026), including abutment panels, caps, decking, and 35 pieces of 50-foot pilings. Madison County, Mississippi solicited bids for the Cauthen Road Bridge Replacement (ITB 98-20260528084902, due June 25, 2026) involving prestressed concrete piles and precast bridge spans. Sarasota County issued an IFB for the Midnight Pass Road Pedestrian Bridge (IFB 262861MN, due July 20, 2026) with steel truss deck, prestressed concrete piles, and concrete end bents. The City of Palm Bay, Florida, on behalf of Brevard County, requested bids for the Fred Poppe Regional Park Bridge and New Roadway (ITB 46ITB26, due August 4, 2026, $1.3 million roadway plus three-span concrete bridge with 18-inch square prestressed concrete piles). Seminole County, Florida issued a Master Services Agreement for Miscellaneous Bridge Repairs (IFB CC494123RTB, estimated $1.2 million, 197 line items) covering routine and emergency bridge maintenance. Jackson County, Mississippi and Lowndes County, Georgia also posted bridge-related construction work in the review period. The concentration of recent activity in Florida reflects ongoing regional infrastructure investment in both vehicular and pedestrian bridge systems, with secondary activity in Mississippi and Georgia.
