UNSPSC 23131514: Mounted stones

UNSPSC 23131514 Mounted stones is a Commodity code covering aggregates and stone materials that state and local governments purchase for road base, fill, and construction applications. Recent solicitations under this code reflect procurement of loose stone materials in bulk quantities rather than finished or fabricated mounted stone products — the abstract code name does not align with what is actually being bought. Columbus Consolidated Government in Georgia solicited bids for stone on an annual contract basis in May 2026, requesting pricing for fourteen stone classifications including #3, #34, and #5 stone, screening materials, crushed stone base, surge stone graded mix, rip-rap types, and graded aggregate base with estimated monthly usage of approximately 200 tons. This type of work — bulk aggregate supply to municipalities and county departments for public works, road maintenance, and capital projects — represents the typical scope under the code. Issuing bodies are predominantly municipal and county governments procuring materials for in-house public works and facilities operations.

The code shows limited recent activity. Geographic spread is narrow; the single substantive opportunity appeared in Georgia (Columbus Consolidated Government). Columbus Consolidated's solicitation used an IFB (invitation for bid) format with a response deadline of June 17, 2026, awarding to two vendors — a Primary and Secondary Contractor selected as the two lowest responsive, responsible bidders. The contract term is two years with three one-year renewal options, fixed pricing for the initial period and documented cost-escalation requests not to exceed five percent thereafter. Delivery is F.O.B. job site within two hours of order placement when specified, or pickup at vendor plant. The code appears to see minimal procurement volume across state and local jurisdictions relative to other construction materials categories.
