UNSPSC 30131604: Stone bricks

UNSPSC 30131604 Stone bricks is a Commodity code that encompasses aggregate and stone materials — including stone classifications (#3, #34, #5 stone), screening materials, crushed stone base, rip-rap, graded aggregate, flagstone, sandstone, granite boulders, and river rock — that state and local governments procure for roadway maintenance, landscaping enhancements, parks operations, and erosion control. Solicitations under this code span a mix of issuing bodies: county public works departments and consolidated governments purchasing stone on standing annual or multi-year contracts; county parks and open space departments establishing pre-qualified vendor lists for project-by-project materials assignments; and municipal public works issuing competitive bids for landscaping improvements that incorporate decorative stone and aggregate. Columbus Consolidated Government and Boulder County Parks and Open Space Department appear as repeat or significant buyers in recent notices.

Recent opportunities reflect two contracting models. Columbus Consolidated Government issued RFB No. 26-0037 (due June 17, 2026) for an annual stone contract with estimated monthly usage of approximately 200 tons across fourteen stone classifications, awarding to two vendors — Primary and Secondary Contractors selected as the two lowest responsive, responsible bidders. Boulder County Parks and Open Space Department solicited a short-list of pre-qualified vendors (SOQ 28626, due May 27, 2026) for landscaping products and erosion control materials over up to five years on a project-by-project basis with no guaranteed volume. Geographic activity includes Georgia (Columbus), Colorado (Boulder County), and Texas (Williamson County), with one multi-state cooperative opportunity through Sourcewell covering Washington-state counties. The City of Fairburn, Georgia's landscape-enhancement IFB (26-013, due June 16, 2026) included decorative rock installation but was primarily a landscaping design and planting scope rather than a commodity stone purchase.
