00015787 Addendum4.docx

This is an Addendum No. 4 issued by the Oregon Department of Transportation (ODOT) for the Prineville Maintenance Station Reroof Project, ITB No. S-73000-00015787. The addendum modifies the original Invitation to Bid documents solely to address needed changes for roof venting details. Specifically, the addendum deletes and replaces Attachment A Plans (the original "00015787 Attachment A Plans.pdf") with a revised version ("00015787 Attachment A Plans REVISED.pdf"). The revisions focus on two details circled with clouds on page 2 of the plans, where ODOT added a ridge detail and revised the eave detail to allow for proper ventilation between the new standing seam metal roof and the existing roof structure. Bidders must acknowledge receipt of this addendum in ITB Section H and are required to be fully responsive to all addendum requirements as if originally stated in the ITB. The deadline for requests for clarification, requests for change, and protests of this addendum is February 19, 2026, at 5:00 PM. The original bid closing date remains February 25, 2026, at 10:30 AM. All other terms and conditions of the original ITB remain in full force and effect unless explicitly modified by this addendum.

No pricing terms, set-asides, incumbent information, or funding amounts are detailed in this addendum document. This addendum serves as a technical clarification and modification instrument to ensure bidders have accurate roof venting specifications and details before submitting their proposals. Failure to acknowledge receipt of this addendum may result in bid rejection.
