Research Buck Creek Cone Penetration Testing

The Oregon Department of Transportation (ODOT), in collaboration with Oregon State University and Portland State University, is seeking a qualified contractor to perform seismic cone penetration testing (SCPTu) with pore water pressure measurement at the Buck Creek Bridge site. The project involves conducting geotechnical investigations, including advancing 2-6 SCPTu soundings to approximately 60 feet depth, performing downhole shear wave velocity measurements, and executing pore water pressure dissipation tests. The contractor must provide specialized equipment capable of measuring pore pressures up to 1500 psi and be prepared to work with complex subsurface materials including fill, colluvium, lacustrine deposits, and diatomaceous silts. The bid is solicited through Invitation to Bid (ITB) #S-73000-00011456, with bids to be submitted electronically through the OregonBuys eProcurement system by April 10, 2025, at 1:00 PM. Bidders must have a minimum of three years of experience providing similar services and submit three professional references from comparable projects. The project is scheduled to start no earlier than April 2025 and must be completed by November 15, 2025, with on-site work expected to take no more than 14 consecutive days.

While no specific small business or Disadvantaged Business Enterprise (DBE) participation goal is explicitly stated, the contract is federally funded and subject to federal requirements, including Buy America provisions. Bidders must provide comprehensive documentation including business classifications, certifications of non-discrimination, compliance with state tax laws, and verification of no legal exclusions. The contract will be awarded to the lowest responsible bidder, with pricing structured across multiple line items including administration, mobilization, equipment, cone penetration testing, standby time, and traffic control. The bid pricing form includes estimated quantities for 300 feet of cone penetration testing, 12 dissipation tests, 60 feet of predrilling, 2 drums, 6 CPT sounding reports, and 8 hours of standby time. The total contract value will be determined through the competitive bidding process, with unit prices to be quoted by potential contractors. Bids will remain firm for 90 calendar days following the bid closing date, and the contract is expected to have a minimum three-year pricing commitment with potential for additional terms.
