UNSPSC 81101522: Earthworks engineering

Earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes. Includes roads, railway beds, causeways, dams, levees, canals, and berms.

UNSPSC 81101522 Earthworks engineering is a Commodity code that encompasses professional design and consulting services for site preparation, grading, drainage, utility coordination, and related earthwork infrastructure improvements on capital projects. State and local governments buy under this code primarily when soliciting engineering consultants to prepare design plans, conduct site surveys, develop construction specifications, and provide construction administration for projects involving soil stabilization, erosion control, stormwater management, fill and embankment work, and infrastructure foundations. The code spans design-phase deliverables through bid support and construction oversight on public infrastructure, buildings, parks, and utility projects. Issuing bodies include municipalities (cities of Dallas, New London, Nashua, Corvallis, and others), counties (Sarasota, DeKalb, Madison), water and transit authorities, regional planning agencies, and special-purpose districts. A mix of state agencies also procure under the code: the California Department of Transportation solicits utility location and potholing services; Georgia Department of Transportation and Oregon Department of Transportation issue design-build and planning services RFQs. Repeat solicitation activity appears concentrated among Texas municipalities and Georgia jurisdictions, with scattered activity across Connecticut, California, Utah, and the Pacific Northwest.

Recent opportunities span stormwater design and flood mitigation (City of Dallas CIZDWU26241E, RFP response due August 21, 2026), underground utility location services (Caltrans IFBs 07A6321 and 07A6322 in Ventura and Los Angeles Counties, bids due July 21, 2026), wastewater and sewer infrastructure design (Madison County RFQ response due June 24, 2026; City of New London landscape and MEP design for Atlantic Street Park, proposals due July 31, 2026), site development and erosion mitigation (Gila River Indian Community design services RFP response due July 10, 2026), and on-call general engineering services across multiple disciplines (West Basin Municipal Water District on-call engineering, proposals due August 21, 2026; City of Tolleson multidisciplinary on-call RFQ, SOQs due August 19, 2026). Geographic activity concentrates in Texas, Georgia, and California, with secondary markets in Connecticut, Arizona, Utah, and Oregon. The code shows consistent demand for fixed-price design services, on-call engineering vehicle establishment, and design-build procurement structures, with responses typically requested within 30–60 days of posting.
