UNSPSC 30131519: Gabion block

Product made by filling natural or processed stone into wire mesh made in the shape of square, circle, oval

UNSPSC 30131519 Gabion block (Commodity) represents erosion control and stabilization materials that state and local governments procure for water management, riprap installation, and stream/channel protection. Recent opportunities reveal that purchasing bodies actually solicit for riprap stone, aggregate materials, and related erosion control supplies rather than pre-assembled gabion units. The City of Wichita procured 1,560 to 1,900 tons each of 18-inch and 24-inch flexible light and heavy stone rip rap under RFB #260112, due July 10, 2026, for stormwater control and creek stabilization tied to the Wichita-Valley Center Flood Control Project. DeKalb County, Georgia issued a three-year multiyear contract ITB for granite rubble stone (one-man and two-man sizes) delivered across multiple county sites with bids due June 17, 2026. Columbus Consolidated Government awarded annually to Primary and Secondary Contractors for fourteen stone classifications including rip-rap types and graded aggregate base, with an estimated 200 tons monthly usage, under a two-year contract with renewal options. Boulder County issued competitive bids for bridge scour riprap installation (approximately 1,100 cubic yards) and highway chip seal aggregate (3,300 tons), with completion windows spanning 45 to 60 working days.

State and local buyers for this code span county departments of public works, transportation and water utilities, city stormwater divisions, and county road/drainage maintenance programs across Kansas, Georgia, Texas, Colorado, Wisconsin, Florida, Oregon, and California. Cities and counties typically establish one-year or multiyear framework agreements with fixed or escalating unit pricing, require delivery within 24 to 48 hours or on-call basis, and apply local-vendor preferences (5 percent for San Bernardino County, 10 percent LBE preference for Philadelphia) where permitted. Recent solicitations emphasize compliance with state department of transportation specifications (Caltrans, CDOT, TxDOT, FDOT, Georgia DOT), pre-qualification of stone sources through independent laboratory testing, insurance minimums of $1 million general liability, and E-Verify registration for public works projects. Activity is consistent and distributed across metropolitan and regional counties; no single geographic concentration dominates. Opportunities range from as-needed service contracts under $100,000 annual spend to substantial three-year multiyear awards and capital project-specific procurements approaching multi-million-dollar values.
