Geotechnical Drilling, Umpqua River Bridge

The Oregon Department of Transportation (ODOT) is soliciting quotes for geotechnical drilling services to support a bridge pier protection project where US101 crosses the Umpqua River near Reedsport, Oregon. The scope of work requires the completion of eight geotechnical holes advanced to design depths of 40 feet below the mudline. Because the fender structures are located in the water, all drilling operations must be performed from a barge. The project is scheduled to begin on or after November 13, with a completion date of December 18 and a final contract expiration of January 30, 2027. The contract will be awarded to a responsible offeror based on price, experience, expertise, product functionality, and suitability for the project's purpose. Requirements for the contractor include providing personnel licensed by the Oregon Water Resources Department and maintaining specific marine insurance. Compliance with federal and state OSHA standards, prevailing wage laws, and Oregon Department of State Lands general authorizations is mandatory. Payment is structured through monthly invoicing with a potential 5 percent retainage, and the agency reserves the right to request personnel replacements within 24 hours if performance or safety standards are not met.
