UNSPSC 11111608: Limestone

UNSPSC 11111608 Limestone is a Commodity code that covers aggregates, stone materials, and related fill products state and local governments procure for infrastructure, landscaping, and construction projects. The recent solicitation record shows the code is applied inconsistently — the Montgomery County prefabricated building for coroners and Sourcewell law enforcement equipment solicitations have no clear connection to limestone procurement — but the core buying activity reflects routine purchases of crushed stone, rubble stone, aggregate base materials, fill dirt, topsoil, and erosion control supplies for maintenance and construction work. Issuing bodies include county governments (DeKalb County, Georgia; Columbus Consolidated Government; Boulder County, Colorado), municipal departments, county parks and open space departments, and cooperative purchasing vehicles such as Sourcewell that aggregate demand across multiple jurisdictions and entity types. Counties and special-purpose districts dominate the recent activity, with work ranging from single-year or multiyear supply contracts to open-ended landscaping material lists with project-by-project assignment.

Recent opportunities span Georgia, Colorado, and the broader Sourcewell network across the United States. DeKalb County issued an ITB for granite rubble stone (one-man and two-man sizes) with a three-year multiyear contract term and bids due June 17, 2026. Columbus Consolidated Government solicited stone on an annual as-needed basis under RFB No. 26-0037 (bids due June 17, 2026), awarding to two vendors — a Primary and Secondary Contractor — for delivery of fourteen stone classifications including crushed base, rip-rap, and graded aggregate base with estimated monthly usage of approximately 200 tons. Boulder County Parks and Open Space Department posted a Statement of Qualifications (SOQ) on May 6, 2026 (due May 27, 2026) to establish a short-list of pre-qualified vendors for landscaping products and erosion control materials including aggregate, stone varieties, fill dirt, and topsoil, with individual project assignments over up to five years. These contracts typically require proof of E-Verify compliance, workers' compensation and general liability insurance, and delivery or haul rates; pricing is often fixed for initial terms with limited escalation options.
