US 101 MP 316 Emergency Woodruff Landslide Geotechnical Drilling and Instrumentation

The Oregon Department of Transportation (ODOT) is seeking a contractor for a geotechnical drilling and instrumentation project along US 101 at Milepost 316, specifically addressing the Woodruff Landslide emergency response. The project requires drilling six boreholes to a depth of approximately 150 feet each, with specific instrumentation installation requirements including slope indicator casing, two vibrating wire transducers (VWT) per casing, and one slope indicator (SI) per casing. Contractors will be responsible for systematic soil sampling at approximately 5-foot intervals and collecting rock core samples. The procurement opportunity is posted with a release date of July 29, 2025, and has a proposal submission deadline of August 13, 2025. Key objectives include comprehensive geotechnical investigation and monitoring to understand and mitigate landslide risks, with ODOT providing the VWT instrumentation and slope tube casing. The contract appears to require specialized geotechnical expertise, geological knowledge, and precise drilling capabilities.

While specific set-aside designations are not explicitly detailed in the available documentation, the project's technical complexity suggests that qualified geological and geotechnical engineering firms with demonstrated experience in landslide investigation and instrumentation will be preferred. The emergency nature of the project implies potential urgency in contractor selection and implementation. Two supporting documents are attached to the contract opportunity: a sample contract (49.docx) and a request for contractor qualifications (00014490 RFCQ.docx), which likely contain additional details about contractor requirements and evaluation criteria. Although the exact budget range is not specified, emergency geotechnical projects of this nature typically involve significant technical expertise and specialized equipment, suggesting a potentially substantial contract value. The project's location along US 101 indicates this is a critical infrastructure stabilization effort with potential implications for transportation safety and regional geological monitoring.
