UNSPSC 81151706: Consultants biostratigraphic analysis

A biostratigraphic consultant plan initiates, coordinates, and reports studies, integrating biostratigraphy and paleontology with complementary stratigraphic data sets including good log, lithology, petrography, seismic, isotope, mineralogy, and chemical elements of cuttings, core and/or outcrop.

UNSPSC 81151706 Consultants biostratigraphic analysis is a Commodity code under which state and local governments procure specialized consultant services for geological and hydrogeological assessments, groundwater characterization, aquifer analysis, and water resource evaluation. The work spans technical assignments including brackish groundwater production zone delineation, aquifer modeling, geophysical interpretation, and well field evaluation conducted by licensed professional geoscientists and hydrogeologists. State and local issuing bodies soliciting under this code include state water agencies (Texas Water Development Board), county water utilities and environmental services divisions (Sarasota County, Volusia County, Florida), and city solid waste and facilities management departments (City of Scottsdale, Arizona; City of DeBary, Florida; Broward County, Florida). Recent opportunities also reflect higher-education contracting bodies (Texas Higher Education Coordinating Board). The scope of work spans groundwater resource characterization with multi-year production volume projections, monitor-well sampling protocols to support permitting compliance, historical well-data compilation and remedial development, hydrogeological studies with aquifer performance testing, and facilities assessment services supporting infrastructure planning and asset management.

Recent activity concentrates in Florida and Texas. The Texas Water Development Board issued RFP 58027RFP0003 on July 6, 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; the work requires ten years of project management and hydrogeology experience, professional geoscientist licensure, and a VetHUB subcontracting plan, with an initial contract term through August 31, 2027, renewable through 2030. Sarasota County, Florida issued RPS solicitation 262824RM in April 2026 for quarterly and monthly groundwater monitoring at the Carlton Memorial Reserve Wellfield, requiring Florida professional engineer or geologist licensure and a three-year initial contract term. Volusia County, Florida conducted RSQ 26SQ65SR in April 2026 for professional hydrogeological and well services across twenty-six production wells and nine treatment facilities, with firms evaluated 25 percent on qualifications, 25 percent on five-year minimum experience, and scoring on a three-year base contract with two optional one-year renewals. Broward County's RFP PNC2130470P1 (February 2026) for roofing and waterproofing consultant services, though nominally outside the code's hydrogeological focus, was tagged under this commodity code, suggesting occasional mislabeling in state and local databases.
