NIGP 91157: C.i.p., Soil Investigation

NIGP 91157, C.I.P., Soil Investigation, is an Item code under which state and local governments procure comprehensive geotechnical engineering services supporting capital improvement and infrastructure design projects. Recent solicitations show the code covers field investigation (boring, cone penetrometer testing, geophysical surveys), laboratory soil and groundwater analysis, foundation and pavement design recommendations, and interpretive reporting compliant with current building and seismic codes. Issuing bodies include municipal utilities, county governments, water authorities, and special-purpose districts (Dalton Utilities, DeKalb County, City of Palm Bay, Beaufort-Jasper Water and Sewer Authority). The work typically requires supervision by licensed professional engineers or geologists and deliverables in both hard-copy and electronic formats.

Recent opportunities span Georgia and Florida. Dalton Utilities issued an RFP on June 26, 2026, for geotechnical investigation supporting design of a gas reciprocating engine generation facility in Whitfield County, Georgia, encompassing 24 borings to 100 feet, cone penetrometer soundings, thermal and electrical resistivity testing, MASW surveys, and laboratory testing for foundation design and corrosion evaluation, with proposals due June 30, 2026. The City of Palm Bay, Florida, issued RFP 30-RFP-26 on April 6, 2026, for design and construction of four production wells at its North Regional Water Treatment Plant, including geophysical logging (caliper, gamma ray, resistivity, acoustic), video logging, and water quality analysis, with bids due April 28, 2026. The Beaufort-Jasper Water and Sewer Authority in South Carolina issued IFB 2026IFB020 on February 19, 2026, for a low-pressure sewer system project requiring site investigation and utility coordination, with bids due March 24, 2026.
