NIGP 44004: Blocks, Glass

NIGP 44004 Blocks, Glass is an Item code for window glass and related materials procurement by state and local governments—specifically the furnishing and installation of glass products including single and double strength, tempered, thermal pane, plexiglass, and related aluminum and screening materials for commercial, industrial, and residential building projects. State and local issuing bodies purchasing under this code include city departments (environmental and general services, housing and community development), county emergency services and partnership agencies focused on hazard mitigation, and special-purpose program offices. The work spans glass installation labor and materials supply across diverse building types and installation scenarios, from standard residential window replacement to high-rise commercial glazing work requiring specialized equipment and crew capacity.

Recent solicitation activity shows Arizona and California jurisdictions pursuing these services. The City of Tucson issued RFP No. 226043 in August 2022 (posted August 5, 2026) for an annual requirements contract for window glass furnishing and installation across the Tucson metropolitan area, targeting commercial and industrial projects through the Environmental and General Services Department and residential housing rehabilitation through the Housing and Community Development Department, with HUD funding and Section 3 compliance requirements including prevailing wage obligations and disadvantaged business enterprise tracking. Tuolumne County, California issued RFQ RFQ-2023-0070 in October 2026 for environmental and historic preservation reviews supporting a wildfire mitigation home-hardening program that includes building retrofit and defensible-space work, though this solicitation focuses on subject-matter expert qualifications rather than direct glass or materials procurement. The Tucson procurement indicates multi-year contract vehicles (one year with four optional extensions) with walk-in counter service and as-needed task ordering, typical of municipal glass and glazing supply contracts serving ongoing maintenance and capital rehabilitation programs.
