UNSPSC 22101909: Slurry tunnel boring machine

A slurry tunnel boring machine (slurry TBM) is a type of underground excavator that removes excavated material by hydraulic means. It is considered a "soft ground" tunnel boring machine (TBM) along with the earth pressure balance tunnel boring machine (EPB-TBM).

UNSPSC 22101909 Slurry tunnel boring machine, a Commodity code, sees minimal recent state and local procurement activity aligned with its nominal scope. The code represents equipment for horizontal boring operations in confined underground spaces, particularly for utility and infrastructure work that minimizes surface disruption. However, the most recent state and local opportunities tagged to this code include an automotive parts supply contract (School Board of Sarasota County), a park and sidewalk extension project (Orange County Public Works), water treatment equipment procurement (Gwinnett County), law enforcement equipment cooperative purchasing (Sourcewell), and wastewater pipe construction (Fort Valley Utility Commission in Georgia) — none of which involve slurry tunnel boring machines or related horizontal directional drilling systems in any direct capacity. The one substantively relevant recent solicitation is Hillsborough County, Florida's sole-source procurement (SS2600161, posted February 20, 2026, challenge deadline February 27, 2026) for a Power Mole Model PD-6 Directional Thrust Boring Equipment from Power Mole Trenchless LLC at an estimated cost of $70,357.66, intended for long, curved bores in confined underground spaces to minimize surface restoration impact. This equipment performs horizontal directional drilling rather than slurry-based tunnel boring, and the procurement was designated noncompetitive sole source and not open to competitive proposals.

Geographic activity is sparse and scattered across Florida, Georgia, California, Minnesota, and Texas, with no clear concentration in any single region or state. Issuing bodies include county water and utility authorities, county public works departments, school districts, and a state cooperative purchasing vehicle. No pattern of repeat buying under this code emerges from the recent opportunities block. The Hillsborough County drilling equipment purchase represents the only directly relevant recent solicitation; all other tagged opportunities reflect coding misalignment rather than genuine slurry tunnel boring machine procurement. Firms pursuing work in horizontal directional drilling and trenchless technologies should monitor Georgia, Florida, and other states with aging underground utility infrastructure, but this code exhibits negligible recent activity in state and local procurement channels.
