This document is an Addendum issued by the Oregon Department of Transportation (ODOT) for Invitation to Bid (ITB) No. S-73000-00014662, specifically for the OR 11: MP 4 to Weston Interchange Chip Seal Project. The addendum primarily extends the bid opening and closing date from September 24, 2025, at 10:00 AM to September 30, 2025, at 2:00 PM, modifying the original solicitation timeline. The project involves a pavement preservation chip seal treatment on Oregon Highway 11 between milepost 4 and 20.38 in Union County, with a project implementation period between June 1 and August 15, and substantial completion required by July 1, 2026, with final completion by August 1, 2026.

The procurement requires electronic bid submissions through the OregonBuys eProcurement system, with the contract to be awarded to the lowest responsible and responsive bidder. Key project elements include temporary traffic control, application of polymer-modified emulsified asphalt, and permanent pavement markings. The contract includes a 10% bid security requirement, compliance with prevailing wage rates, and Buy America provisions. Liquidated damages are set at $1,100 per calendar day for missing the final completion date, with additional charges for lane closures and traffic disruptions. The project will utilize aggregate materials from the ODOT-owned Dry Creek Quarry in Umatilla County, with an estimated material requirement of 7,000 cubic yards, and includes a comprehensive one-year warranty period for addressing any performance failures.
