UNSPSC 72141201: Caisson drilling service

The building of caissons owned by others

UNSPSC 72141201 Caisson drilling service (Commodity) names underground drilling work performed to install large-diameter shafts and foundation systems, though state and local governments procure this code more often for horizontal directional boring, geotechnical site investigation, water well construction, and utility line installation across roadway and infrastructure projects. Recent solicitations show mixing of true caisson-shaft work with broader subsurface drilling services under the same code classification.

State and local issuing bodies soliciting under this code span special-purpose water and utility districts, state departments of transportation (notably Oregon and Georgia), counties, cities, and school districts. The Oregon Department of Transportation, Georgia Department of Transportation, and Pinellas County School District appear multiple times in recent months. Work is dispersed across the Southeast (Georgia, Florida, Mississippi, Tennessee), Southwest (Texas), and West (Oregon, California), with no geographic concentration. Representative recent opportunities include Fort Valley Utility Commission (Georgia) RFP for approximately 4,000 linear feet of 20-inch PVC effluent pipe installation using jack-and-bore methods under railroad crossings (response due July 24, 2026); Pinellas County School District (Florida) ITB for directional boring and hand trenching services on as-needed basis with contract value approximately $250,000 (response due June 12, 2026—noted as past due); and Oregon Department of Transportation RFQ for geotechnical drilling at multiple landslide sites with nine drill holes totaling 540 feet and specialized soil sampling (response due May 21, 2026). The Texas State University System issued an IDIQ RFQ for geotechnical and materials testing services including subsurface exploration, capped at $500,000 across a three-year term (qualifications due July 21, 2026). Most opportunities are project-specific or as-needed contracts with fixed or estimated scopes; guaranteed minimums are rare. Drilling support for highway, bridge, water infrastructure, and environmental remediation work drives current activity.
