Attachment C-1_Bid Reference Document for Bridge Removal.pdf

This is a bid reference document memo from the Oregon Department of Transportation (ODOT) Bridge Engineering Section addressed to Region 1 Maintenance & Operations regarding the NB Boone Bridge (I-5 over Willamette River at MP 283.11) Joint Rehabilitation Project. The document, dated November 5, 2025, provides contractors with essential reference materials for understanding the scope of work related to the removal of existing Temporary Work Access and Containment (TWAC) structures at existing Pier 1. The memo includes a plan sheet from existing bridge plans and photographic documentation of the current TWAC platform to enable contractors to develop accurate bids for the removal work. The TWAC platform is noted to be in poor condition and is identified for removal as part of the broader bridge rehabilitation project. The document establishes the approximate location and limits of the structures to be removed, allowing bidders to assess the complexity and requirements of the work.

The bid reference document serves as a communication tool to ensure contractors have sufficient technical information to reasonably understand the removal requirements and submit appropriate bids. No specific pricing terms, contract duration, award dates, or other contractual details are addressed in this memo, as it functions solely as a technical reference document to support the bidding process for the NB Boone Bridge Joint Rehabilitation Project. The document was prepared by Paul Strauser, Region 4 Bridge Lead Engineer, and distributed to regional project management and engineering leadership to facilitate contractor comprehension of existing conditions prior to bid submission.
