UNSPSC 30131503: Stone blocks

UNSPSC 30131503 Stone blocks (Commodity) encompasses the supply and delivery of aggregate materials, decorative stone, and related products that state and local governments purchase for road maintenance, landscaping, and erosion control work. Recent solicitations show state and local buyers procuring crushed stone, rip-rap, granite boulders, flagstone, sandstone, stackable stone, river rock, and fill materials on both one-time and annual contract bases. Issuing bodies include county governments (Columbus Consolidated Government in Georgia, Hillsborough County in Florida, Boulder County in Colorado), municipal departments (City of Fairburn, Georgia), state agencies (Georgia Department of Driver Services), and special-purpose districts (Atlanta BeltLine, Inc.). The mix reflects parks and open space departments, public works operations, and facility management groups seeking reliable suppliers for landscape enhancements, utility restoration, and capital repair projects.

Recent activity centers in Georgia, Florida, and Colorado. Columbus Consolidated Government issued an RFB in May 2026 for stone on an annual contract basis covering fourteen classifications with approximately 200 tons of monthly usage, awarding to the two lowest responsive bidders on a two-year term with renewal options. Hillsborough County issued an ITB in March 2026 for sand delivery to support sandbag operations on an as-needed basis across county locations with a three-year contract valued at $617,490. Boulder County Parks and Open Space Department posted a solicitation in May 2026 for a short-list arrangement providing landscaping products and aggregate materials (road base, crusher fine, rip-rap, recycled asphalt) and stone varieties on a project-by-project basis over up to five years. The Georgia Department of Driver Services issued an eRFQ in April 2026 for synthetic stacked stone installation at customer service centers. City of Fairburn solicited landscape enhancements including decorative rock installation within roadway medians under IFB 26-013 with a mandatory site visit in May 2026. The code shows active procurement across multiple jurisdictions and commodity classes, with most opportunities structured as annual or multi-year contracts with competitive bidding to establish supplier panels for ongoing material delivery.
