UNSPSC 20111622: Reverse circulation drill

A type of drilling rig that crushes base rock by attaching a special roller bit to the drill rod block section, and discharges crushed excavated soil to the surface by sucking the circulation water and crushed rock with a vacuum pump through the drill rod pipe.

UNSPSC 20111622 Reverse circulation drill is a Commodity code that in recent state and local procurement activity covers equipment and services for refrigerant extraction, recovery, and destruction rather than drilling operations. The City of Tucson Environmental and General Services Division solicited EPA-certified refrigerant reclamation services to extract gases from appliances and products at its sustainability campus, requiring extraction at minimum every two weeks, comprehensive documentation of gas recovery and destruction, and EPA-approved recovery equipment operated by certified technicians. State and local issuing bodies under this code include municipal environmental divisions and cooperatives purchasing on behalf of multiple jurisdictions; Sourcewell, a Minnesota local government unit and service cooperative, has posted a parallel RFP for law enforcement equipment that appears to have been mislabeled under this code and does not reflect the actual refrigerant-extraction scope. The geographic spread is limited in the available recent opportunities, with documented activity in Arizona (City of Tucson, Pima County) and a multi-state cooperative purchasing vehicle administered through Minnesota.

The City of Tucson RFP No. 240011 for Gas Extraction and Removal, posted September 30, 2026 with response due September 19, 2024, represents the most recent representative opportunity aligned to the code's actual scope. The contract calls for extracting gases from approximately 50 units per week with detailed pricing line items for Freon, mixed gas, and refrigerant removal, plus hourly labor rates for general, after-hours, and holiday work. The initial contract term runs one year with up to four additional one-year renewals, and a pre-submittal conference was held March 19, 2024 via Microsoft Teams. The procurement references Federal Transit Administration Terms and Conditions, which typically include disadvantaged business enterprise participation provisions. No incumbent vendor is named, and the contract remains open to qualified EPA-certified refrigerant reclaimers with demonstrated environmental compliance capability.
