This is a geotechnical drilling and instrumentation scope of work document for the Oregon Department of Transportation (ODOT) related to stabilization efforts at the US101 MP304.6 Retz Creek Landslide project in Curry County, Oregon. The project requires subsurface drilling services including the drilling of six geotechnical drill holes to depths up to 215 feet, totaling approximately 870 feet of drilling using mud rotary, HQ3-Wire Line coring, and potentially sonic drilling techniques. Key deliverables include soil and rock sampling, installation of slope inclinometer casings, and vibrating wire transducers. The contractor must mobilize and begin work within 30 calendar days of the Notice to Proceed, with project completion required by November 1, 2025. A mandatory project kickoff meeting must be held before drilling commences. Proposal submissions were due via OregonBuys by July 1, 2025, and evaluation will be based on responsiveness and lowest responsible bid pricing.

Bidders must demonstrate a minimum of three years of experience in geotechnical sampling and provide a drill crew with at least one licensed monitoring well constructor and an experienced drill helper. The contractor is responsible for providing all equipment, machinery, tools, lighting, supplies, materials, fuel, water delivery, setup, safety equipment, and personnel necessary to complete the work. The project is funded through federal aid (OR 2024-02) and requires compliance with Title VI non-discrimination provisions, Buy America provisions, and Cargo Preference Act requirements. Comprehensive insurance documentation, a completed Responsibility Inquiry Form, business registry information, and references demonstrating comparable project experience are mandatory. While no specific small business set-aside is included, Disadvantaged Business Enterprise (DBE) guidelines and federal funding requirements apply.
