Geotechnical Drilling for Winchester Creek Bridge Replacement

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.

Description

The Western Federal Lands Highway Division (WFLHD) of the Federal Highway Administration (FHWA) is preparing a geotechnical subsurface exploration program for the Winchester Creek Bridge in Douglas County, Oregon. The primary goal is to assess the subsurface conditions for designing a replacement bridge structure.  Agency partners include the U.S. Forest Service.

The project is located at latitude N 43.6751° and longitude W 124.1788° in the northeast ¼ of the southwest ¼ of Section 7, Township 22 South, Range 12 West of the Bureau of Land Management (BLM) Public Land Survey System (PLSS).
