This project is a joint research effort between ODOT, Portland State University, and Oregon State University focusing on a site underlain by diatomaceous soils. The selected contractor will provide all labor, equipment, and materials to conduct five cone penetration tests, twelve U2 dissipation tests, and sixty-five shear wave velocity tests in accordance with ASTM D5778-20. Key deliverables include a full text and graphical report submitted within 14 days of the final sounding, with electronic data provided in ASCII, CSV, or XLSX formats. The contract is awarded to the lowest responsive and responsible bidder, with a final completion date of November 17, 2027, and a designated winter no-work period. Performance is subject to strict safety and environmental guidelines, including OSHA compliance, the use of ANSI Class 3 reflective safety vests, and adherence to ODOT Best Management Practices for drilling. Because the project involves federal-aid highway construction, the contractor must comply with FHWA Form 1273, Davis-Bacon prevailing wage provisions, and Build America, Buy America requirements. Administrative terms include monthly invoicing by the 10th of each month, payment within 30 calendar days, and a potential 5 percent retainage on invoices.
