NIGP 135: Bricks, Clay, Refractory Materials, Stone, and Tile Products

NIGP 135 Bricks, Clay, Refractory Materials, Stone, and Tile Products is a Class code under which state and local governments procure materials for facility and infrastructure repair, restoration, and construction—including granite pavers, concrete furnishings, aggregate, erosion control supplies, and specialized stone products for public spaces and grounds maintenance. The code captures both high-visibility civic projects and routine maintenance purchasing across cities, counties, school districts, and special-purpose districts. Recent solicitations show activity spanning granite paver replacement on waterfront installations (Tampa Riverwalk), concrete park furnishings for beach facilities (Sarasota County), landscaping aggregate and stone for county parks (Boulder County), and gravel supplies for school district grounds (Parkway School District, Missouri). Issuing bodies range widely—municipalities like Tampa and Conroe, counties in Orange, Bergen, and Sarasota, school districts, and regional authorities such as West Basin Municipal Water District and Sacramento County Airport. The mix reflects both capital project procurement (waterfront improvements, pedestrian infrastructure) and routine operational supply contracts where quantities and timing remain flexible across multiple sites and fiscal periods.

Geographic activity concentrates in Florida (Orange County, Sarasota County, Tampa, Meriden) and California (San Mateo, Boulder County), with representation in the upper Midwest, Southwest, and Northeast. Representative recent opportunities include the City of Tampa's Coldspring Granite Pavers procurement (IFB 26P00257, April 2026, single-source materials for Riverwalk restoration), Sarasota County's concrete park furnishings bid (RFQ 2026QQ660, March 2026, fourteen benches and trash receptacles for Siesta Beach), and Boulder County's landscaping products and erosion control materials short-list (SOQ28626, May 2026, open-ended pricing list for project-by-project assignments over five years). Most opportunities operate on a competitive, lowest-responsive-bidder award basis with prevailing wage and insurance requirements common on larger projects. Activity is steady but episodic, driven by facility-condition assessment cycles, capital replacement schedules, and seasonal maintenance planning rather than continuous demand.
