UNSPSC 81151702: Stratigraphic geology

UNSPSC 81151702 Stratigraphic geology is a Commodity code that encompasses subsurface geological and hydrogeological analysis work, including aquifer characterization, groundwater production zone delineation, and related technical studies that state and local water authorities and environmental agencies procure to support resource management and planning decisions. The code sees solicitation primarily from specialized state water development and environmental boards rather than general municipal or county purchasing offices, reflecting the technical depth required for the work.

The Texas Water Development Board posted the most substantial recent opportunity under this code: an RFP issued July 6, 2026, for brackish groundwater production zone analysis across portions of the Carrizo-Wilcox, Queen City, Sparta, and Yegua aquifers in Central Texas, with proposals due August 6, 2026, and contract start anticipated for September 1, 2026. The scope requires ten years of project management experience in advanced scientific studies, professional geoscientist licensure, and GIS subsurface mapping capabilities; deliverables include production area shapefiles, modeling files, technical reports, and thirty- and fifty-year production volume determinations across fourteen counties in central Texas. The initial contract term runs through August 31, 2027, with possible one-year renewals through 2030. A Veteran Heroes United in Business (VetHUB) subcontracting plan demonstrating good faith effort is required, and professional liability insurance of $50,000 per occurrence must be obtained. The code shows minimal recent activity outside this single substantive opportunity; the other two posted opportunities (an irrigation system installation by the City of DeBary, Florida, and open educational resources grant support by the Texas Higher Education Coordinating Board) are misattributed to stratigraphic geology and reflect municipal construction and educational services procurement, not geological analysis work.
