Pennsylvania is seeking contractors for statewide geological coring and related field services.
- **Government buyer:** Pennsylvania Department of Conservation and Natural Resources (DCNR), Bureau of Geological Survey (BGS); statewide work locations.
- **OEMs and vendors:** No OEMs, manufacturers, or commercial vendors are named.
- **Services requested:** Sonic PQ core drilling in sediment and bedrock, traditional diamond NX core drilling in bedrock, mobilization and demobilization, water hauling, borehole grouting and decommissioning, site restoration, and Department-requested standby time. Quantities are not specified; drilling and grouting are priced by the linear foot, while other services use flat-rate or hourly pricing as applicable.
- **Technical requirements:** Capability to drill at least 200 feet below graded surface and work in remote or off-road locations. Dry drilling is expected for sediment unless the Department directs otherwise. Core recovery requirements are at least 80% in sediment and 90% in bedrock, subject to geological conditions. Larger core diameters up to 6 inches are acceptable without changing the stated per-foot price.
- **Additional requirements:** Contractors must restore drill sites, water access locations, and affected routes. Boreholes must be sealed in accordance with PennDOT Publication 222. The Department provides core boxes and drilling oversight, including borehole logging.
- **Work locations:** Services may be ordered statewide and are expected most often in Pennsylvania’s glaciated regions, particularly the northwest and northeast.
- **Contract term:** One initial year, with up to four additional annual renewals by mutual agreement. Unit-price increases may be negotiated at renewal, capped at 3%.
