NIGP 74586: Seal Coating

NIGP 74586 Seal Coating is an Item code under which state and local governments procure crack sealing, fog sealing, sealcoat application, and related pavement surface protection on parking lots, streets, and roadways. The work ranges from narrowly scoped annual crack-sealing contracts for municipal streets to comprehensive multi-scope pavement rehabilitation projects that bundle seal coating with overlay, striping, and infrastructure repairs. Issuing bodies span city public works departments (Arlington, Jackson), county facilities and transportation agencies (Solano County, Santa Clara County, Williamson County, Michigan DOSC), sanitation districts (Santa Clara County Sanitation District No. 2-3), school districts (Lawton Community Schools), and municipalities (Town of Palm Beach). Surface preparation per industry standards (SSPC for protective coatings, MDOT specifications for fog seal and crack fill) is routine; materials must often meet specified manufacturers or federal standards (coal tar emulsion, thermoplastic, waterborne paint). Work includes pressure cleaning, heat lancing, and wire-wheeling; application windows are constrained by temperature and humidity thresholds. Bonding (performance, payment, and maintenance bonds) is standard for contracts exceeding $50,000 to $100,000 depending on issuer; prevailing wage applies on federally funded or state-prevailing-wage projects.

Recent solicitation activity concentrates in California and Michigan. The County of Solano, Department of General Services is procuring painting and coating services on the Fairfield Justice Campus Asset Protection Project (FEMA-funded flood mitigation), with proposals due October 19, 2026, under a multi-prime structure requiring SSPC-standard surface preparation and specified coating materials on structural steel, galvanized steel, concrete, and masonry. The City of Arlington is establishing an annual requirements contract for crack sealing services for its Public Works Department, with proposals due October 22, 2026. Santa Clara County Sanitation District No. 2-3 issued an ITB for the Structural Defect Repair Project Phase 2 covering thirty-five sanitary sewer mainline point repairs and pipe-burst replacements with secondary seal-coating scope (due September 17, 2026). The City of Jackson solicited crackfilling, sealcoating, and striping on downtown and recreation center parking lots under CDBG funding, with federal compliance and small-business participation mandates (due July 23, 2026). Michigan DOSC and the Michigan Department of Transportation jointly posted multiple fog seal and pavement marking RFQs for the MDOT Detroit Operations Service Center through August 2026, with 10 percent Service-Disabled Veteran-Owned Business pricing preferences. Williamson County, Texas issued an IFB for fog sealing (26IFB39, due May 5, 2026). Scope complexity and bonding thresholds indicate consistent mid-range contract values; federal funding (FEMA, CDBG) and state prevailing-wage requirements appear regularly. No single jurisdiction dominates; activity reflects distributed maintenance cycles across municipal and county networks.
