UNSPSC 41113828: Sand density cone apparatus

A tester that measures the unit weight of earth with the maximum particle radius of 5cm or less under the sand replacement method at the site.

UNSPSC 41113828 Sand density cone apparatus is a Commodity code covering soil testing and measurement equipment, though recent state and local opportunities under this code reflect broader geotechnical laboratory and field testing services rather than the sand density cone device alone. State and local governments procure soil compaction testing equipment, cone penetrometer systems, and comprehensive materials testing services through this code. Issuing bodies include state departments of transportation (Texas Department of Transportation, Michigan Department of Transportation), municipal utility authorities (City of Key West operating as Keys Energy Services), and county governments (City of Augusta, Henry County). The scope spans field density testing, Modified Proctor compaction tests, cone penetrometer test (CPT) truck-mounted sounding units, electrical insulating oil testing for power transformers, concrete compressive strength testing, asphalt analysis, and soil classification work—services typically ordered on an on-call or as-needed basis with unit pricing or task orders.

Recent activity concentrates in Texas, Michigan, Florida, and Georgia. The Texas Department of Transportation posted an IFB for a Proctor Soil Compactor with Soil Analyzer (solicitation 601340000067218) with responses due October 27, 2026. Michigan Department of Transportation awarded an RFP for a truck-mounted Cone Penetrometer Test sounding unit to Applied Research Associates, Inc. at $1,011,529.00 following a July 16, 2026 proposal deadline. The City of Augusta, Georgia issued RFP 26-176 for on-call geotechnical testing services covering field and laboratory testing over a five-year contract with proposals due September 11, 2026. Henry County, Georgia posted RFQ #27-08 for on-call materials and field testing services with qualifications due September 9, 2026, requiring GDOT prequalification as a mandatory eligibility gate. Keys Energy Services in Key West issued two solicitations (1026 and 0426) for electrical insulating oil testing services with responses due April 17, 2026 and February 20, 2026 respectively, each requiring three years base term with optional one-year renewals and $2 million general liability insurance.
