UNSPSC 81151910: Airborne geophysical acquisition

Airborne geophysical acquisition is a process of measuring the variation of several key physical or geochemical parameters of the earth. The most important parameters measured are conductivity, magnetic susceptibility, rock density, radioactive element concentration, and reflectance spectra.

UNSPSC 81151910 Airborne geophysical acquisition is a Commodity code that captures geophysical data collection and analysis services, though recent state and local procurement activity under this code shows minimal alignment with the nominal category. The three recent opportunities tagged to this code span irrigation system installation, brackish aquifer production zone analysis, and open educational resources technical assistance—work that falls outside the typical scope of airborne geophysical surveying. The issuing bodies include municipalities (City of DeBary, Florida), state water and higher-education agencies (Texas Water Development Board and Texas Higher Education Coordinating Board), and special-purpose districts or state boards. None of these opportunities reflect airborne or ground-based geophysical data acquisition as commonly understood in the sector.

The code shows recent activity in Texas and Florida with a response deadline of August 6, 2026, for the TWDB brackish aquifer analysis (RFP 58027RFP0003), which is the only opportunity among the three with substantive geophysical or hydrogeological content. That solicitation requires professional geoscientist licensure, ten years of hydrogeology experience, three years with geophysical log documentation and GIS subsurface mapping, and a VetHUB subcontracting plan; the contract term runs through August 31, 2027, with renewal options through 2030. The City of DeBary irrigation improvements (Bid 03-15, due April 10, 2015) and the THECB open educational resources technical assistance (RFP 781-6-CB-14, due May 21, 2026) are unrelated to geophysical work. The code shows limited recent relevant activity; firms pursuing state and local geophysical procurement should verify code assignment before committing bid resources.
