PW1755-26 Addendum 3.pdf

This is Addendum 3 to the Invitation to Bid for Marion County, Oregon's North Fork Slide Stabilization project (PW1755-26), issued on January 7, 2026. The addendum addresses clarifications requested by prospective bidders regarding project documentation and insurance requirements. The document responds to two substantive questions: the first addresses the labeling and availability of existing contour data for the slide repair, clarifying that a DWG file containing the existing ground surface with contours has been posted for download, supplemented by a Surface - Existing Ground.xml file compatible with standard software programs used by contractors. The second addresses builder's risk insurance requirements, confirming that such coverage is not mandated for this project as it was not specified in the Special Conditions, though the general provision framework allowing for such requirements is referenced in General Condition 0017.70(j).

The addendum serves as an essential clarification document for bidders preparing proposals for this critical infrastructure project involving extensive earthwork and drainage construction. All prospective offerors are required to acknowledge and incorporate the information contained in this addendum into their bid submissions. The clarifications provided ensure bidders have access to necessary technical documentation and understand the actual insurance requirements applicable to the project, reducing ambiguity in the bidding process and enabling more accurate cost estimation and project planning.
