UNSPSC 11111901: River rock

Rock that has been smoothed by water and friction

UNSPSC 11111901 River rock is a Commodity code that encompasses the supply and delivery of natural stone materials—including river rock, rip rap, granite rubble, crushed aggregates, and related stone products—that state and local governments procure for infrastructure maintenance, erosion control, stormwater management, and road construction. Recent solicitations show issuing bodies purchasing river rock and allied stone products for highway maintenance, bridge scour mitigation, drainage system repairs, and landfill operations. The code attracts a diverse mix of state departments of transportation (Mississippi DOT, Texas DOT, Oregon DOT), county governments (DeSoto County Mississippi, Ada County Idaho, Pinellas County Florida, DeKalb County Georgia, Santa Clara County California), municipal public works departments (City of Austin, City of Wichita, City of Fort Worth, City of Amarillo, City of Huntsville Texas, City of Lavonia Georgia), and special districts (Orlando Utilities Commission, Boulder County Parks and Open Space Department). State transportation departments and county maintenance operations emerge as repeat buyers; Mississippi DOT and DeSoto County appear multiple times in the recent record, as do Texas jurisdictions across state and local levels.

Recent activity concentrates in Texas, Mississippi, California, Florida, Georgia, Oregon, and Idaho. Representative recent solicitations include Mississippi DOT's sealed bid for crushed aggregates under RFX 3160008330 (IFB, bids due November 2, 2026) with contract term January 1 through June 30, 2027, specifying materials must meet Mississippi Standard Specifications for Road and Bridge Construction 2017 and conform to MDOT Materials Division testing, with award to lowest responsive bidders meeting specifications; Texas DOT's bid for 2-inch crushed limestone (IFB, bids due October 16, 2026) for highway maintenance and construction on a unit cost basis; City of Amarillo's ITB for 2,000 tons of rock crusher screenings for street maintenance (ITB 267-26 YM, bids due October 15, 2026) with local-vendor preference under Texas Local Government Code Section 271.9051 within 5% of low bid; and City of Wichita's RFB for rip rap stone in three categories totaling 3,960 tons (RFB #260112, bids due July 10, 2026) supporting the Wichita-Valley Center Flood Control Project. Typical contract terms range from one year with optional renewals through three-year multiyear agreements, with pricing submitted on unit or tonnage basis F.O.B. destination, delivery within 24 hours to five working days of notification, and source pre-qualification and materials testing required at vendor expense for nonconforming deliveries.
