The Oregon Department of Transportation (ODOT) is soliciting bids for project SPR892_879: Phase 3 CPT Wickiup, a joint research effort with OSU and PSU. The contract involves conducting a geotechnical investigation at Wikiup Junction on US Route 97, specifically focusing on seismic cone penetration testing with pore water pressure measurement (SCPTu) in areas underlain by diatomaceous soils. The scope of work includes five CPT soundings, twelve U2 dissipation tests, and sixty-five shear wave velocity tests at one-meter intervals. Deliverables consist of a comprehensive text and graphical report detailing tip resistance, sleeve friction, pore pressure, and shear wave velocity, to be submitted within 14 days of the final sounding. The project is scheduled to begin no earlier than September 1, 2026, with a final completion date of November 17, 2027. A mandatory no-work period is established from November 18, 2026, through March 30, 2027, due to winter weather. The contract is awarded to the lowest responsive and responsible bidder. Compliance requirements include adherence to ASTM standards, ODOT best management practices for drilling, FHWA Form 1273 federal-aid construction provisions, and Davis-Bacon wage acts. Field operations must strictly observe site maps, specifically maintaining a 50-foot distance from railroad tracks. Bidders must submit all documentation, including a pricing form and cover sheet with three professional references, via the OregonBuys portal by the specified deadline.
