About this file
This is Addendum No. 1 to the contract documents and specifications issued by the City of Eugene, Oregon for the Amazon Prairie Mitigation Bank - Phase 2 construction project, effective June 5, 2026. The addendum modifies the original bidding documents by replacing the Bid Schedule dated May 19, 2026 with a revised schedule dated June 5, 2026, and updates four detail and plan sheets related to spillways, fish screen details, concrete headwall construction, and ditch berms. Additionally, the addendum modifies Special Provision 00150.15 regarding Construction Stakes, Lines, and Grades to require 3D machine grade control for initial rough grading while mandating that finish grading be completed without such control to ensure smooth, rounded transitions between graded features and to avoid hard-edged, rectangular shaped pools or berms. The revised Bid Schedule includes line items for mobilization, erosion control, construction entrance, compost filter sock, CWRR reports, general excavation of 7,922 cubic yards, embankment geotextile installation on 5,000 square feet, loose riprap placement of 135 square yards, storm pipe installation totaling 301 linear feet of various sizes, flashboard risers, concrete headwall construction, habitat logs covering 5,808.80 square yards, coir fabric installation of 1,376 square feet, river rock spillway installation, removable picket weirs, and fish screen boxes totaling 160 units as an alternate bid item. Electronic bids must be submitted through OregonBuys by June 10, 2026 at 2:00 p.m., and all bidders are required to acknowledge receipt and acceptance of this addendum by signing and submitting it with their bid submission, with unsigned bids potentially deemed non-responsive.
The addendum does not present pricing information, set-asides, or funding sources, as these elements are contained in the primary contract documents. All bidders must incorporate the effects of the addendum changes into their respective bid items and adjust their total bid amounts accordingly. Clarification questions regarding the addendum or project should be directed to Lindsay Smith at 541-729-4301. The addendum was signed and certified by Doug Singer, P.E., Interim City Engineer on June 5, 2026 and includes Adobe Acrobat Sign verification links confirming the document's authenticity and execution date.
