About this file
This document is Addendum 2 to an Invitation to Bid (ITB) No. S-73000-00011456 issued by the Oregon Department of Transportation (ODOT) for Research Buck Creek Cone Penetrating Testing. The addendum modifies the original ITB, extending the bid closing date to April 14, 2025, at 2:00 PM, and making several key changes to the scope of work and technical specifications. The project involves seismic cone penetration testing (SCPTu) with pore water pressure measurement, requiring downhole shear wave velocity and pressure wave velocity measurements. The bid pricing form has been updated to include two mobilizations and traffic control, with estimated quantities including 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 addendum revises the Sample Contract to reflect updated bid pricing structure and adds line items for administration, mobilization, traffic control, and other project-specific services. Bidders are required to acknowledge the addendum on the Bid Coversheet, with failure to do so potentially resulting in bid rejection. The project is part of a geotechnical investigation supporting a pile static load test at a site with complex subsurface materials, including fill, colluvium, lacustrine deposits, and diatomaceous silts. While no specific small business or Disadvantaged Business Enterprise (DBE) participation goals are mentioned, the contract is federally funded and subject to federal requirements, including Buy America provisions.

Finally to extend the bid closing date for this solicitation to Monday April 14th 2025 @ 2:00 PM.
1. Document labelled “Attachment A Scope of Work and Technical Specifications” Section labelled Seismic Cone Penetration Sounding with Pore water Pressure Dissipation (SCPTu), paragraph 3 is amended as follows. New language is Italicized and Underlined.
Downhole shear wave velocity and pressure wave velocity measurements shall be performed during testing. The contractor will provide a seismic source for generating waves at the ground surface and an instrumented cone containing the receiver(s) necessary (e.g., geophone(s)) to detect pressure and shear wave arrival times.
2. Document labelled “Sample.Contract.docx” Table in Section 4.2 Delivery Schedule and Prices, subsection Contractor Provided Unit And Total Bid Pricing Will Be Inserted Here is deleted in its entirety and replaced with the following:
