Geotechnical Drilling for Winchester Creek Bridge Replacement

**Buyer:** Western Federal Lands Highway Division
**Posted:** November 03, 2026
**Respond By:** November 17, 2026
**Identifier:** 69056727Q000006
**NAICS:** 238910, 541360, 541380, 541370

The Federal Highway Administration is seeking geotechnical drilling services to investigate subsurface conditions for the Winchester Creek Bridge replacement in Douglas County, Oregon.
- **Government buyer:** Federal Highway Administration (FHWA), U.S. Department of Transportation, Western Federal Lands Highway Division (WFLHD); the U.S. Forest Service is identified as an agency partner. The categorical-exclusion document names Wendy Schmidt.
- **Opportunity:** Solicitation 69056727Q000006, a total small-business set-aside. No OEMs, commercial vendors, or product part numbers are named.
- **Requested work:** Two bridge-foundation borings, BH26-01 and BH26-02, generally 50–130 feet deep, with drilling, rock coring, sampling, borehole completion, and sample delivery. The boring table estimates 30 feet of auger and 80 feet of HQ core for BH26-01 (maximum depth 130 feet; 30 SPT samples) and 30 feet of auger and 20 feet of HQ core for BH26-02 (maximum depth 50 feet; 14 SPT samples). No Shelby samples are estimated in that table.
- **Pricing schedule:** Includes mobilization, drilling/coring, pavement cores, SPT and optional Shelby sampling, suspension logging, flagging, traffic control, utility locating, site preparation, asphalt patching, sample shipping, water-level testing, and related crew/equipment costs. Amendment A001 replaces the original price-schedule page; its listed quantities are retained separately below because they differ from the original schedule and boring table.
- **Notable requirements:** Perform P-S suspension logging in one boring through the upper 100 feet for seismic design; use traffic control and rolling closures as needed; locate and avoid utilities; patch pavement; manage and dispose of drill water and cuttings; and install flush-mounted, traffic-rated monuments in paved areas where borings are instrumented. Locations may shift up to 50 feet. The environmental document identifies a seasonal work window to avoid sensitive nesting periods.
- **Duration:** Fieldwork is estimated at one to two weeks; the RFQ also anticipates up to six business days, while the environmental document estimates about 6–7 full days per boring. No option years are specified; an extension of services may be permitted for up to six months.
- **Estimated value:** Approximately $30,000–$100,000; the solicitation materials provided do not state a government estimate.
