UNSPSC 81151901: Geophysical surveys

UNSPSC 81151901 Geophysical surveys (Commodity) covers field analysis and subsurface characterization work that state and local governments procure for water resource planning, site assessment, and infrastructure development. Recent solicitations show state and local bodies buying geophysical and hydrogeological analysis, brackish aquifer production-zone mapping, aerial detection survey services, and related technical documentation—though the recent opportunities tagged to this code span a wide range of work including park irrigation system installation and educational resource grant administration that fall outside typical geophysical survey scope. The issuing bodies include state water and environmental agencies (Texas Water Development Board, Idaho Department of Lands), county governments (Orange County, California), and municipal parks departments (City of DeBary, Florida). State higher education coordinating boards also appear in the recent-opportunities block but their solicitations involve educational grant administration rather than geophysical work and likely represent tagging misalignment.

Texas and Florida show recent activity, with the most substantive geophysical opportunity being the Texas Water Development Board's RFP 58027RFP0003, posted July 6, 2026, with proposals due August 6, 2026, soliciting brackish groundwater production-zone analysis across fourteen Central Texas counties (Atascosa, Bastrop, Bexar, Caldwell, DeWitt, Fayette, Gonzales, Guadalupe, Karnes, Lavaca, Lee, Live Oak, Williamson, and Wilson). The TWDB requires ten years of hydrogeology experience in the project area, professional geoscientist licensure, three years with geophysical log documentation and GIS subsurface mapping, and mandates a VetHUB subcontracting plan; the initial contract term runs through August 31, 2027, with optional renewal through August 31, 2030. The Idaho Department of Lands issued IFB 1377 for Aerial Detection Survey Services on June 30, 2026, with bids due July 16, 2026, though scope details and technical requirements are not available in the source material. The Orange County, California IFB 2993004402JDW (due April 24, 2026) for survey equipment and related services to support five landfill facilities involves procurement of surveying instruments and consumables rather than geophysical analysis services proper, indicating category tagging mismatch. Beyond these, the code shows little activity clearly aligned with geophysical survey work.
