UNSPSC 20111600: Drilling and operation machinery

UNSPSC 20111600 Drilling and operation machinery is a Class code that encompasses on-call geological exploration drilling services, well development and destruction, and specialized drilling equipment procurement by state water agencies and transportation departments. State and local governments buy statewide drilling capacity on call-up contract, with work including rotary drilling, sonic drilling, core sampling, geophysical testing, and well destruction across multiple facility locations and counties. The primary issuing bodies are state water resources and transportation departments procuring multi-year, on-call drilling services to support infrastructure development and environmental assessment; city public works departments also solicit smaller-scale hydraulic and equipment repair services tagged under the code. California Department of Water Resources emerges as a standout repeat buyer, issuing separate contracts for rotary drilling (IFB #10217383, due June 3, 2026), sonic drilling (IFB #10218183, due June 10, 2026), and cathodic protection services including related installation work (IFB #10215192, due June 16, 2026). The City of Phoenix Public Works Department solicited hydraulic hose repair and replacement services for its equipment fleet (IFB 27-FSD-0353, due August 13, 2026) on an as-needed, call-out basis with response-time guarantees, and the Texas Department of Transportation issued bids for debris removal blade systems and hydraulic removal attachments (solicitations posted March–May 2026).

Recent activity concentrates heavily in California, driven by the Department of Water Resources' statewide geological exploration and infrastructure maintenance contracts across all 58 counties, with secondary activity in Texas (TxDOT district procurements), Arizona (Phoenix), Florida (Department of Transportation District Four storm sewer inspection), Connecticut, and Pennsylvania. The California DWR solicitations dominate the code's recent volume: rotary drilling contracts require California C-57 Well Drilling licenses, three-year terms with two one-year renewal options, mandatory 3 percent Disabled Veteran Business Enterprise participation, and anticipated start dates of July–October 2026; sonic drilling similarly requires C-57 licensing and statewide availability across all 58 counties with anticipated October 2026 start. Cathodic protection services on five State Water Project facility divisions (Oroville, Delta, San Luis, San Joaquin, and Southern Field) require California Class A and C-10 licenses, five years' cathodic protection experience, and a service shop location in California, with mandatory 3 percent DVBE participation and a June 16, 2026 response deadline. All three DWR solicitations use three-year initial terms with one-year renewal options, structured compensation on hourly labor rates plus materials-at-cost-plus-15-percent, and prevailing wage requirements. The Phoenix hydraulic hose IFB structures work on quarter-hour labor increments with separate premium rates for after-hours service, a 90-day materials warranty, and a three-year initial term with two one-year renewal options commencing November 1, 2026.
