The Oregon Department of Transportation (ODOT) is seeking a qualified contractor for geotechnical drilling and instrumentation services at US 101 Milepost 344.5, specifically for the Arch Rock Landslide project in Crook County. The procurement requires drilling three holes to approximately 200 feet each, with precise specifications including mud rotary drilling, HQ3-Wire Line coring, and installation of vibrating wire transducers (VWTs) and slope inclinometer casings. The contractor must sample soil at approximately 5-foot intervals and collect rock core, with ODOT providing the VWT instrumentation and slope tube casing. Required qualifications include a drill crew with at least three years of experience and a licensed monitoring well constructor. The solicitation will be conducted through OregonBuys, with bids evaluated to determine the lowest responsible and responsive bidder. Key deadlines include a proposal due date of September 2, 2025, with project work to commence within 30 calendar days of the Notice to Proceed and to be completed no later than December 12, 2025. A mandatory project kickoff meeting will be held to discuss project objectives, safety precautions, and environmental management.

The contract appears to have no specific small business set-aside target, and it is federally funded (OR 2025-01) subject to Buy America and Cargo Preference requirements. Bidders must submit multiple forms including a Competitive Quote Form, Price Quote Form, and References Form, with the successful contractor required to provide insurance certificates and comply with Oregon business registration requirements. The total contract amount will be determined based on unit prices submitted for various drilling activities, including administration, mobilization, drilling methods, sampling, instrument installation, and standby time. Comprehensive insurance requirements and environmental protection measures are mandatory, with payment contingent upon successful completion of drilling operations and submission of required documentation to the Oregon Water Resources Department. While no specific incumbent vendor is mentioned, the project involves complex geotechnical work with specific instrumentation and sampling protocols. The contractor will be responsible for providing all necessary equipment and personnel, implementing safety protocols, and managing drilling spoils throughout the project's duration.
