NIGP 15508: Bridges, Prefabricated (Not Installed)

NIGP 15508 Bridges, Prefabricated (Not Installed), an Item code, encompasses prefabricated bridge components—steel trusses, precast concrete deck panels, abutment assemblies, and modular bridge sections—that state and local governments procure for assembly and installation on roadways, pedestrian trails, and stream crossings. Recent solicitations show counties, cities, and special-purpose authorities buying fabricated truss bridges, precast concrete bridge materials, and modular steel bridge systems delivered to site for erection by construction contractors. Issuing bodies include county boards of supervisors (Coahoma County and Lowndes County, Mississippi; Okaloosa County, Florida; Carroll County and Lowndes County, Georgia), city governments (Sheridan, Oregon), special transit or trail authorities (Atlanta Beltline, Inc.), and county governments (Orange County and Sarasota County, Florida). Carroll County, Georgia and Orange County, Florida appear multiple times in recent postings, indicating sustained bridge infrastructure procurement activity in those jurisdictions. Work scoped under the code ranges from single-span pony truss bridges fabricated to AASHTO LRFD standards with cast-in-place concrete decks to precast concrete slab units, abutment panels, and pilings delivered under firm-fixed-price contracts; fabrication, shop testing, coatings, and freight are included in supplier pricing.

Geographic activity concentrates in the Southeast, with recent solicitations in Mississippi, Georgia, Florida, and Oregon. Representative opportunities include Carroll County, Georgia's IFB for a 130-foot pre-engineered pony truss bridge on Victory Church Road with bids due October 13, 2026, requiring AISC Bridge Fabricator certification (minimum Intermediate Bridge Fabricator rating with Fracture Control Endorsement), ten years of experience, and five successful prior pony-truss projects; Okaloosa County, Florida's ITB for precast and prestressed concrete bridge materials (abutment panels, deck, pilings) for the Bone Creek Bridge, bids due April 29, 2026; and the State of Maine Department of Administrative and Financial Services' RFQ for four modular all-steel skidder bridges for temporary stream crossings in logging operations, quotations due July 30, 2026. Most fabrication procurements require sealed bids, 5–10 percent bid security, and 100 percent performance and payment bonds; bidders must carry Professional Liability and General Liability insurance ($1 million to $4 million in aggregate depending on the project scope). Prevailing wage and Buy America compliance are standard on federally funded projects.
