NIGP 91431: Composites

NIGP 91431 Composites, an Item code, encompasses renovation, repair, and infrastructure-upgrade work at state facilities, community colleges, and county healthcare institutions — framed by recent solicitations that span building remodels, HVAC replacements, seismic compliance upgrades, water and sewer line work, roof repairs, and elevator modernizations. State and local governments buying under this code are primarily Washington state agencies (departments of corrections, children/youth and families, social and health services, ecology, labor and industries, veterans affairs, enterprise services, and military), Washington community colleges (Highline, South Seattle, Everett, Big Bend, Clark, Pierce, Shoreline, Tacoma, Skagit Valley, Whatcom, Columbia Basin, Lake Washington Institute of Technology, and Clover Park Technical College), and Santa Clara County, California (for medical center seismic compliance and infrastructure projects). The issuing bodies are predominantly state departments and public two-year colleges, with secondary activity from county health systems and special districts. Washington state generates the overwhelming majority of recent composite-code activity; California accounts for a smaller share driven by healthcare facility seismic upgrade mandates.

Recent opportunities include competitive bids across a range of infrastructure and building services: Highline College's Building 3 renovation (IFB, due November 18, 2026), South Seattle College's auto facility HVAC replacement (IFB, due November 20, 2026), Everett Community College's parks window repairs and Veteran's Center remodel (IFBs, due November 20 and November 18, 2026), Big Bend Community College's Building 1800 ATEC remodel (IFB, due November 11, 2026), and Washington Department of Corrections' shower repair rebid at Airway Heights Corrections Center (IFB, due December 2, 2026). Santa Clara County is also active with multiple prequalification-gated design-build and traditional bid solicitations for healthcare facility seismic upgrades at Santa Clara Valley Medical Center, O'Connor Hospital, and Saint Louise Regional Hospital (prequalification and proposal stages ongoing through October 2026). Washington Department of Enterprise Services, Department of Social and Health Services, and other state agencies are soliciting fire alarm upgrades, lighting conversions, water and sewer infrastructure work, and facility-wide renovations on rolling schedules through October and November 2026. The code reflects capital facilities and building-systems work—primarily infrastructure refresh and compliance-driven upgrades—with activity concentrated in Washington community colleges and state institutional facilities, and episodic but high-value healthcare seismic projects in California.
