UNSPSC 11111500: Dirt and soil

UNSPSC 11111500 Dirt and soil is a Class code under which state and local governments procure bulk soil and fill materials for construction, landscaping, infrastructure, and site restoration work. Recent solicitations show state and local buyers acquiring clean fill dirt, topsoil, sand, base course aggregates, and specialized soils (screened, debris-free, or meeting DOT specifications) for delivery to parks, landfills, water treatment facilities, roadways, and public works sites. The issuing-body mix spans city public works departments (Arlington, St. Petersburg, Tucson, Austin, Norwalk), county boards of commissioners (Brevard, Hillsborough, Pasco, Sarasota, Orange, Marion, Clay, Sarasota), state transportation agencies (UDOT, Caltrans, Maryland Environmental Service), regional authorities (Solid Waste Authority of Palm Beach County), and special districts (Boulder County Parks and Open Space). Several jurisdictions appear multiple times: the City of Arlington has posted multiple solicitations for water infrastructure and fill materials; Florida counties (Brevard, Pasco, Sarasota, Orange, Hillsborough) represent a concentration of activity for sand, fill dirt, and aggregate delivery contracts.

Recent opportunities span the continental United States with notable concentration in Florida, Texas, Utah, Colorado, Maryland, California, and the Northeast. Representative recent solicitations include the City of Arlington's 39-inch Water Transmission Main Improvements project (IFB 260269WUW23031, bids due July 16, 2026), requiring abandonment of concrete water main with contractors prequalified for Water and Sanitary Sewer work; the City of St. Petersburg's supply and delivery of 400 cubic yards of double-sifted clean soil for the TASCO Mud Wars youth event (RFQ QUOTE26238, quotes due June 11, 2026, delivery July 2, 2026); Maryland Environmental Service's sourcing, testing, and delivery of up to 450,000 cubic yards of cover soil to Brown Station Road Sanitary Landfill in Prince George's County (IFB 1274015, bids due July 15, 2026); and the Utah Department of Transportation's Region 4 Fish Lake Base Course supply and delivery of 865 cubic yards of Untreated Base Course material (IFB UDOT260276CN, bids due May 28, 2026, delivery by June 30, 2026). Multi-year as-needed contracts and annual requirements agreements dominate the category, with firms qualifying for standing supplier lists through pricing submissions and references. Minimum insurance requirements typically run $1,000,000 commercial general liability per occurrence, and many solicitations require E-Verify compliance and compliance with state DOT specifications for material composition and gradation.
