UNSPSC 30131506: Natural rock slab

UNSPSC 30131506 Natural rock slab is a Commodity code encompassing rock materials—primarily granite, stone aggregate, and dimensional stone products—that state and local governments procure for trail construction, site stabilization, landscaping, and public works infrastructure. Recent solicitations show two distinct procurement patterns: bulk aggregate and dimensional materials for capital projects and maintenance work, and specialty stone products for landscaping and erosion control. DeKalb County, Georgia solicited granite rubble stone (one-man and two-man sizes) under a three-year multiyear ITB, and Columbus Consolidated Government sought multiple stone classifications including crusher fine, rip-rap, and graded aggregate base under a two-year annual contract with options to renew. Boulder County Parks and Open Space Department requested a list of qualified vendors for landscaping stone varieties—flagstone, sandstone, and granite boulders—alongside aggregate, fill materials, and erosion control supplies on an open-ended basis. Farmington City, Utah issued sealed bids for trail construction including rock steps, rock stairways, and rock retaining walls as components of the Lower Farmington Creek Trail Project. The solicitations reflect purchasing by county governments, municipalities, and special-purpose park and open-space districts across multiple states.

Procurement activity under the code spans Utah, Georgia, Colorado, and Florida in recent months. DeKalb County's granite rubble stone ITB closed June 17, 2026, and Columbus Consolidated Government's stone contract ITB also closed June 17, 2026, with awards going to two vendors (Primary and Secondary) selected as the two lowest responsive, responsible bidders. Boulder County's erosion control materials and landscaping stone solicitation (SOQ28626) closed May 27, 2026, establishing a short-list of pre-qualified vendors for project-by-project task orders over five years with tiered competitive quoting thresholds based on project value. Farmington City's trail construction IFB (FARMINGTONLFCT) closed July 16, 2026, with unit-price bidding on 16 line items including rock elements and bridge construction, requiring substantial completion by September 30, 2026 with $500 per day liquidated damages for delay. The code shows moderate recent activity driven by capital trail and park infrastructure projects and routine municipal and county aggregate purchasing through multiyear term contracts and qualifying lists rather than single-award arrangements.
