NIGP 91390: Maintenance and Repair, Viaduct

NIGP 91390 Maintenance and Repair, Viaduct is an Item code under which state and local governments procure upgrades, renovations, and specialized system installations at bridge and viaduct structures, including detection systems, drainage rehabilitation, pavement work, and seismic compliance retrofits. Recent solicitations show city and county purchasing offices issuing ITBs, RFPs, and RFQs for viaduct-related infrastructure projects. Santa Clara County dominates the recent activity with multiple seismic-compliance opportunities across healthcare facilities and county infrastructure, followed by significant projects in Florida (Casselberry, DeBary), Texas (Midland), Kentucky (Louisville), and Georgia (Columbus, DeKalb). The work spans emergency flood and over-height vehicle detection systems, structural repairs to aging drainage and utility infrastructure, ADA and code-compliance upgrades, and multi-phase building renovations at medical centers and transit-adjacent facilities. Typical scopes require contractors to manage complex sequencing across operational sites, coordinate with regulatory bodies (HCAI, GDOT, DOT), comply with prevailing-wage and Buy America requirements on federally funded work, and maintain performance and payment bonds equal to 100 percent of contract value.

Santa Clara County has posted the most active pipeline, including design-build prequalification for the Regional Medical Center Seismic 4/5 Upgrade (due October 23, 2026 proposal submission after September 16 prequalification), O'Connor Hospital NPC 4/5 Seismic Compliance (due September 24, 2026), Saint Louise Regional Hospital NPC 4/5 Seismic Compliance prequalification (due September 28, 2026), and two additional hospital building upgrades with prequalification deadlines October 14, 2026. Outside California, Louisville Metro is executing the Via-Smart Project (IFB due May 19, 2026), a federal SMART grant-funded viaduct safety initiative installing over-height and flood detection at four sites with Kentucky prevailing wage and Buy America compliance; the City of Casselberry, Florida is procuring the Eastbrook Water Main Replacement Phase I ($9.36 million, ITB due August 6, 2026 with questions due July 23, 2026) requiring Davis-Bacon compliance and American Iron and Steel provisions; and the City of Midland, Texas solicited utility improvements at Golf Course Drive and Midkiff Road with local-vendor preference under Texas Local Government Code 271.9051 (ITB due October 8, 2026). Prequalification and design-build structures gate entry on multiple Santa Clara projects, narrowing competition to demonstrated seismic and healthcare construction capability.
