UNSPSC 30121709: Ungraded crushed rock

UNSPSC 30121709 Ungraded crushed rock is a Commodity code that encompasses the supply and delivery of raw stone materials—including rip rap, granite rubble, base course aggregates, decomposed granite, and crushed stone in various grades and sizes—used by state and local governments for infrastructure, stormwater management, erosion control, and road construction projects. Recent solicitations show state and local buyers purchasing fractured rock chips for chip seal programs, riprap for bridge scour mitigation and streambank protection, flexible and untreated base course for roads and parking lots, crushed aggregates for surface treatments, and granite rubble stone for general construction fill and landscaping. Issuing bodies span transportation departments (state DOTs and county public works), cities and counties procuring road materials on standing contracts, water and utility authorities managing flood control and infrastructure projects, parks and recreation departments, and special-purpose districts. The City of Wichita, Utah Department of Transportation (Region 3 and Region 4), Dane County Wisconsin, Boulder County Colorado, and Sarasota County Florida emerge as repeat buyers; Texas Department of Transportation, Mississippi Department of Transportation, California Department of Forestry and Fire Protection, and multiple municipal public works departments also solicit regularly under this code.

Recent opportunities span the continental United States, with heavy concentration in the West (California, Utah, Colorado), Upper Midwest (Wisconsin, Minnesota), and South (Texas, Georgia, Florida). The City of Wichita issued RFB #260112 due July 10, 2026, seeking 1,560 tons of 18-inch rip rap, 1,900 tons of 24-inch heavy stone rip rap, and 500 tons of 5×9 stone for the Wichita-Valley Center Flood Control Project, with pre-qualification of stone sources required and a one-year initial term plus two optional one-year renewals. Denton County Texas issued ITB #26-2913 due June 4, 2026, for Flexible Base Grade 1 Type A material meeting Texas Department of Highways specifications, with delivery to two county facilities, 200-ton minimum daily deliveries, and a July 1, 2026 contract start. The City of Austin Parks and Recreation Department solicited IFB #8600 BYS1053 due April 28, 2026, for decomposed granite gravel delivery to hike and bike trails, estimated 7,250 tons annually, with 24-hour delivery windows and a 24-month initial term plus three optional 12-month renewals. Boulder County Colorado issued multiple bids: BID26-26 due April 2, 2026, for 3,300 tons of chip seal aggregate meeting CDOT specifications 703.05, and BID26-126 due April 21, 2026, for removal and installation of riprap at two bridges with 1,100 cubic yards of riprap and substantial site restoration. Cities and counties typically award to the lowest responsive and responsible bidder; multi-year standing contracts with quarterly or annual rebid cycles are standard, allowing both single-award and multiple-award structures depending on delivery geography and vendor capacity.
