UNSPSC 81151805: Bathymetric surveys

UNSPSC 81151805 Bathymetric surveys, a Commodity code, spans state and local procurement for underwater and subsurface mapping, water-body characterization, and hydrological data collection services. Recent state and local opportunities under this code reflect a mix of water resource assessment, groundwater investigation, and aquatic-environment mapping—work performed by environmental engineering firms, specialized surveying and geotechnical consultants, and technology platforms that process sonar and geophysical data. Issuing bodies include state fish and wildlife agencies, university facilities departments, fire districts conducting infrastructure planning, and city public-works and parks offices. The Florida Fish and Wildlife Conservation Commission issued a single-source purchase notice (SS16450, due July 31, 2026) for a three-year subscription to BioBase LLC's EcoSound cloud platform, which processes aquatic sonar data to map vegetation abundance, water depth, and substrate composition; the contract value is estimated at $350,000 over three years. The University of Texas at Austin released a Request for Qualifications (26PSS002, due July 17, 2026) for architect/engineer firms to perform a Campus Geological and Hydrogeological Study, including consolidation of subsurface data into a web-based GIS geodatabase and evaluation of groundwater beneficial uses to address historical groundwater intrusion in campus buildings.

Geographic activity centers on Florida and Texas. Beyond the two primary opportunities, the code sees scattered activity across municipal and special-purpose districts conducting environmental assessments tied to parks, stormwater management, and facility planning. The Pinellas Suncoast Fire & Rescue District's continuing professional services RFQ (26001, due December 1, 2025) explicitly names hydrologic services as one of six offered categories, though the scope encompasses broader design and engineering work. The City of Detroit's forest management RFP (544805, due May 22, 2026) references ecological baseline data collection and monitoring frameworks aligned with forestry rather than bathymetry per se, signaling that some local solicitations tag survey-adjacent work under this code despite thematic mismatch. The code shows limited recent depth; most opportunities reflect episodic, project-specific demand for specialized subsurface characterization rather than sustained procurement volume.
