About this file
This is Addendum #1 to an Invitation to Bid issued by Marion County, Oregon's Public Works Department for the North Fork Improvements Project (PW1719-25), effective January 21, 2026. The addendum clarifies key project specifications and requirements through a question-and-answer format addressing 12 substantive inquiries from prospective bidders. The project encompasses earthwork and drainage, asphalt paving, and electrical work, including luminaires, conduit, wiring, and an informational kiosk. Paving section depths are specified by station on the contract plans, with existing pavement thickness matching required at culvert trenches and tie-ins as detailed in the standard drawings. Traffic control is to be deployed as needed, anticipated for culvert installation, paving operations, and Loop Road tie-ins to North Fork Road, while most Loop Road work may proceed with closures. The contract end date is October 22, 2026, when all work shall be complete. The addendum confirms that bidders must be prequalified through the Oregon Department of Transportation in at least one class of work (Earthwork and Drainage, Asphalt Paving, or Electrical), with prequalification required at least 10 days prior to the bid opening on February 11, 2026.
The addendum establishes that asphalt quantities in the bid schedule follow design quantities as interpreted under the 2024 Marion County General Conditions, while traffic control utilization is flexible and not restricted to daylight hours. Notably, the contractor is responsible for utility service coordination and meter installation, and must furnish luminaires per the contract's special provisions on LED roadway lighting systems. The kiosks are to be fully contractor-designed and constructed per contract plans and special provisions, with no county-specified vendor requirements or additional aesthetic or architectural review requirements beyond the contract documents. No known utility conflicts beyond those shown in the contract plans have been identified. This is a federally funded project subject to Davis-Bacon Act prevailing wage requirements and federal "Buy America" and "Build America Buy America" provisions, with no Disadvantaged Business Enterprise set-asides specified.
