NIGP 92690: Subsurface Testing, Environmental

NIGP 92690 Subsurface Testing, Environmental, an Item code, encompasses geotechnical investigation, environmental site assessment, remedial design, materials testing, and laboratory analysis services that state and local governments solicit to support infrastructure projects, contaminated site remediation, water-quality compliance, and construction materials verification. Recent solicitations show state departments, county agencies, cities, and school districts sourcing Phase I and II environmental assessments, soil borings and geotechnical characterization, concrete and asphalt testing, groundwater monitoring, drinking water and wastewater analysis, roofing and waterproofing assessments, and engineering design services tied to site conditions. The work is typically structured as continuing or on-call contracts with task orders issued as projects are identified, with individual project caps ranging from $200,000 to $500,000 in professional fees and requiring licensed engineers, accredited laboratories, and specialized certifications such as Florida FDOT qualification or New Jersey Licensed Site Remediation Professional credentials.

Recent activity spans Florida, Georgia, New Jersey, and Texas, with issuing bodies including the City of Casselberry and City of Bradenton (continuing services for stormwater, lakes management, and environmental testing via RFQ under Florida Statutes Section 287.055); Hillsborough County Capital Programs (RPS-26-00367, miscellaneous subsurface investigation and testing, $6 million estimated value, proposals due November 3, 2026); Hillsborough County Public Schools (water and wastewater laboratory services, ITB due September 24, 2026); the City of Augusta (geotechnical testing for utilities, RFP 26-176, proposals due September 11, 2026); the City of Houston (professional environmental consulting services for federally funded projects under NEPA and Clean Water Act compliance, RFQ PES2026-0016, responses due November 5, 2026); the New Jersey Department of Environmental Protection (remedial investigation and design services, contract T2621, quotes due November 20, 2026); and Atlanta Beltline, Inc.
