ADDENDA 1 HARDIE PLANK PROJECT.doc

This is Addendum #1 to an Invitation to Bid (ITB) issued by the Oregon Department of Transportation (ODOT) for the Carpenterville Highway 255 MP355.49 Culvert Replacement project, referenced as S-29100-00004849. The addendum modifies two critical aspects of the original bid specifications: it changes the bid opening date from November 15, 2022 at 2:00 PM to November 14, 2022 at 2:00 PM, and it revises the quantity of Hardie Trim 1x5x144 (item #2) from the original amount to 680 units. This addendum constitutes a material change to the ITB and must be signed and returned by the bid closing date; failure to do so may result in bid rejection. The addendum references two supporting documents and becomes part of the original ITB upon execution.

Contractors submitting bids for this culvert replacement project must acknowledge receipt and acceptance of this addendum by providing an authorized signature, company name, and date on the form included in the addendum document. The change in bid opening date accelerates the original schedule by one day, requiring bidders to adjust their submission timelines accordingly. The increased quantity specification for Hardie Trim materials reflects a scope adjustment that impacts both material costs and project deliverables. All other terms, conditions, and specifications from the original ITB remain in full force and effect unless specifically modified by subsequent addenda.
