Addendum No. 1 Summary - Steel Bridge Ramp Girder Strengthening Project

This is Addendum No. 1 to the Invitation to Bid (ITB) issued by the Oregon Department of Transportation (ODOT) for ITB No. S-73000-00015265, a steel bridge ramp girder strengthening project in Multnomah County near the Steel Bridge in Portland. The project scope includes installing 224 internal shear anchors, implementing crack sealing across 150 linear feet, and completing temporary work zone traffic control. The addendum's primary purpose is to revise critical project dates that were originally established in the base ITB. The revised project start date remains "After issuance of Notice to Proceed June 22, 2026," with substantial completion rescheduled from June 19, 2026 to September 16, 2026, and final completion extended from June 30, 2026 to September 30, 2026. The addendum also incorporates three additional Special Provisions sections (SP00223, SP00228, and SP00765) into Exhibit 5 - Specifications and six Standard Drawings (TM800, TM820, TM821, TM840, TM842, and TM844) into Exhibit 6 - Plans. Bidders must acknowledge receipt of this addendum by December 22, 2025, at 5:00 pm, and this acknowledgment requirement supersedes the original ITB submission deadline.

The addendum does not modify pricing, set-asides, or funding requirements. All bidders must comply with the original ITB requirements, including State Buy America provisions mandating domestically produced steel, iron, coatings, and manufactured products; Oregon prevailing wage rates for BOLI Region 2; and bonding requirements of 100 percent of the contract award amount. The project is estimated between $250,000 and $500,000 for bonding purposes, and contractors must maintain commercial general liability and commercial automobile liability insurance with minimum limits of $1,000,000 per occurrence. Liquidated damages of $700 per calendar day apply for missed substantial completion dates, with an additional $500 penalty per 15-minute increment for unauthorized lane closures. The project will be funded through state funds, contingent upon ODOT receiving sufficient appropriations.
