NIGP 98975: Soil Sampling and Preparation Services

NIGP 98975 Soil Sampling and Preparation Services is an Item code representing geotechnical investigation, subsurface characterization, and materials testing work that state and local jurisdictions procure to support infrastructure design, construction oversight, environmental remediation, and facility planning. Recent solicitations show state and local agencies routinely buy comprehensive geotechnical engineering services — borings, cone penetrometer soundings, laboratory testing of soil and concrete, asphalt analysis, foundation design recommendations, and chemical corrosion assessment — delivered through RFQs, RFPs, and continuing-services contracts structured as task-order vehicles or annual retainers. Issuing bodies include county capital programs departments, cities, transit authorities, university systems, and special-purpose utilities; Hillsborough County (Florida), the City of Tucson, Henry County (Georgia), Bartow County (Georgia), and the Texas State University System appear repeatedly in recent postings. The work typically requires GDOT prequalification in Georgia, AASHTO accreditation and ASTM certification compliance, and Florida PE licensure where environmental or engineering services cross state boundaries. Compensation is negotiated on hourly-rate, lump-sum, or time-and-expense bases, with individual project caps often set between $50,000 and $500,000 per work order.

Recent opportunities span the Southeast and Southwest, with notable concentration in Florida and Georgia. The City of Tucson issued RFQ 270124 (due September 10, 2026) seeking approximately eight on-call geotechnical and materials testing consultants at an estimated annual budget of $300,000 with individual projects capped at $250,000. Hillsborough County Capital Programs posted RPS-26-00367 (due November 3, 2026) for miscellaneous subsurface investigation and testing services valued at $6 million on a four-year continuing agreement, requiring Florida-licensed engineering firms and FDOT-certified laboratories. Henry County, Georgia issued RFQ 27-08 (due September 9, 2026) for on-call materials and field testing services with GDOT prequalification required and services issued as task orders on an as-needed basis. The Texas State University System solicited an IDIQ contract (RFQ due July 21, 2026) for geotechnical, construction material testing, and environmental assessment services capped at $500,000 across multiple institutions. The Dalton Utilities project (proposal due June 30, 2026) required a comprehensive geotechnical investigation with 24 borings, laboratory analysis, and design recommendations for a reciprocating engine generation facility, exemplifying the depth of technical scope routinely demanded.
