UNSPSC 81151901: Geophysical surveys

UNSPSC 81151901 Geophysical surveys is a Commodity code that encompasses subsurface investigation and hydrogeological characterization services purchased by state agencies and regional water authorities. State and local governments procure these services primarily for aquifer evaluation, groundwater resource assessment, well field analysis, and water supply planning, often bundled with technical reporting, GIS mapping, and stakeholder engagement around brackish or potable groundwater production zones. The work requires professional licensure in geology or engineering and typically demands multi-year project management experience in scientific studies, geophysical logging, subsurface mapping, and hydrogeological analysis within specific regions or aquifer systems.

The Texas Water Development Board and Volusia County Water Resource and Utilities Services Division are the primary active buyers under this code, with supplementary activity from Sarasota County and other Florida water authorities. Recent solicitations show a geographic concentration in Texas and Florida. The Texas Water Development Board issued RFP 58027RFP0003 in July 2026 for brackish groundwater production zone analysis across the Carrizo-Wilcox, Queen City, Sparta, and Yegua aquifers in Central Texas, with proposals due August 6, 2026 and an initial contract term through August 31, 2027. Volusia County issued an RSQ (Request for Statement of Qualifications) 26SQ65SR on April 13, 2026 for professional hydrogeological and well services including well evaluation, design, permitting, geophysical surveys, aquifer performance testing, and monitoring data evaluation, with proposals due April 9, 2026 and a three-year initial term. Sarasota County's April 14, 2026 RPS solicitation for Carlton Water Quality Monitoring (62824RM) seeks groundwater monitoring and sampling at a wellfield with quarterly and monthly sampling cycles on a three-year CCNA contract. The Idaho Department of Lands also issued IFB 1377 for Aerial Detection Survey Services on June 30, 2026 with a July 16, 2026 deadline, though the full scope is not publicly disclosed. Texas set-aside activity includes VetHUB subcontracting requirements on the TWDB contract, while Florida procurements do not reference disadvantaged enterprise restrictions.
