NIGP 45001: Adhesives and Sealants (Not Otherwise Classified)

NIGP 45001 Adhesives and Sealants (Not Otherwise Classified), an Item code, encompasses concrete sealants, asphalt pavement sealants, joint systems, and adhesive tapes procured by state transportation departments, county and municipal public works agencies, and transit authorities for infrastructure maintenance and preservation. State and local buyers use this code for both labor-intensive sealant application services on concrete and asphalt surfaces and material supply contracts for specialized high-performance sealants meeting DOT, air-quality, and temperature-performance standards. The issuing-body mix spans state DOTs (Missouri Department of Transportation), regional transit authorities (Orange County Transportation Authority), county public works offices (Dallas County), and cities (Peoria, Arizona). Work solicited includes concrete sealant application at transportation facilities and parking structures, pavement preservation through slurry seal and micro seal applications on municipal roadways, bridge joint systems using cellular polyurethane foam and silicone sealants meeting freeze-thaw and UV resistance specs, and specialty adhesive tapes for infrastructure repair.

Recent opportunities cluster in the Southwest and Upper Midwest. The Orange County Transportation Authority issued IFB 250318 in October 2026 for concrete sealant services—surface preparation, penetrating sealer, acrylic sealer, epoxy/polyurethane sealer, and application at twelve facilities plus OC Streetcar platforms, estimated at $250,000 for one year with bids due October 14, 2026; the contract requires California Contractor's License classifications C-8, C-61, or D-06, three years of concrete sealant experience, prevailing wage compliance, and DBE participation. Missouri Department of Transportation issued IFB closing October 20, 2026, for an open-cell foam joint system—cellular polyurethane foam with epoxy primer and silicone sealant—covering multiple joint sizes and depths, available as a blanket purchase agreement for cooperative purchasing by Missouri counties and cities, with 10% domestic preference, MBE/WBE encouragement, and service-disabled veteran preference. The City of Peoria, Arizona, solicited pavement management preservation through IFB P260051 in May 2026, seeking polymer-modified slurry seal Type II or Type III application with an estimated annual expenditure of approximately $1.7 million and a five-year contract term. Dallas County and MoDOT Southwest District posted shorter-duration opportunities for fusion tape and CRAFCO sealants with application equipment rental as-needed through mid-2027.
