UNSPSC 30131503: Stone blocks

UNSPSC 30131503 Stone blocks (Commodity) covers decorative and structural stone materials that state and local governments buy for landscaping, infrastructure, and public works applications. Recent solicitations show purchasing of crushed aggregate classifications, flagstone, sandstone, granite boulders, rip-rap, decorative rock in assorted colors and sizes, and stackable stone, alongside erosion control materials and fill products. Issuing bodies include county governments (Columbus Consolidated Government, Boulder County Parks and Open Space Department, Williamson County), cities (City of Fairburn), and special-purpose cooperative procurement vehicles (Sourcewell on behalf of multiple Washington counties and nationwide participating entities). The scope reflects both routine, high-volume commodity purchases—such as monthly stone deliveries for public works—and project-specific landscaping installations with specimen-quality materials and site-specific delivery requirements.

Activity concentrates in the Southeast and Mountain West regions. Columbus Consolidated Government (Georgia) posted an RFB on May 14, 2026 (bids due June 17, 2026) for an annual stone contract covering fourteen stone classifications with estimated monthly usage of approximately 200 tons, awarded to two vendors on a fixed-price two-year term with optional three-year renewals. Boulder County Parks and Open Space Department (Colorado) solicited qualifications on May 6, 2026 (responses due May 27, 2026) for a five-year pre-qualified vendor list supplying fill dirt, topsoil, aggregate, granite boulders, sandstone varieties, and erosion control materials on an as-needed basis. The City of Fairburn (Georgia) issued an IFB on May 21, 2026 (bids due June 16, 2026) for median landscape enhancements including decorative rock installation and plant materials with a mandatory site visit. Sourcewell (Minnesota) issued a broader cooperative RFP #061626 (due June 16, 2026) nominally for law enforcement equipment but unrelated to stone blocks—no relevant stone-block activity appears under that solicitation.
