NIGP 90742: Geotechnical - Soils

NIGP 90742 Geotechnical - Soils, an Item code, encompasses field and laboratory testing, soil classification, foundation analysis, subgrade preparation, and materials inspection that state and local governments solicit on as-needed and project-specific bases to verify construction quality, assess site conditions, and support infrastructure development. Issuing bodies include county governments, city procurement offices, water districts, university systems, and transit authorities. Representative work includes geotechnical and materials testing for capital projects (Washington County, Oregon, RFP 2026.088-RFP, due October 14, 2026), materials testing and geotechnical services for construction across multiple sites (Denton County, Texas, RFSQ 262930, due October 29, 2026), and on-call geotechnical engineering support for facilities projects (City of Tucson, RFQ 270124, due September 10, 2026). The code sees activity across multiple regions, with recent solicitations in Texas, Georgia, Florida, Oregon, California, Wisconsin, and Arizona. Work is structured in three primary models: as-needed on-call agreements with hourly or unit-rate compensation; fixed-term framework contracts supporting capital improvement programs; and project-specific tasks for discrete construction initiatives. Mandatory credentials typically include professional engineering licenses, state laboratory certifications (ODOT Quality Assurance, AASHTO accreditation, CCRL participation), field technician certifications, and proof of insurance (Professional Liability typically $1 million per occurrence / $2 million aggregate). Contract values range from $300,000 five-year maximums (Washington County) to $30 million (Broward County transit program), with most county-level procurements in the $250,000 to $500,000 range over three to five years. Performance is local to the issuing jurisdiction; Washington County reimburses mileage up to 60 miles from the administrative center. The code remains active across state and local procurement, with consistent demand from transportation, utilities, water, facilities, and general infrastructure programs.
