About this file

This is an addendum document issued by the City of Pendleton for the North Main Grind and Overlay Project, dated March 5, 2026, with a bid opening scheduled for March 19, 2026, at 2:00 pm. The addendum provides clarifications and modifications to the original bid documents and contract specifications for a pavement overlay project. Key modifications include updates to Special Specifications Section 12 regarding Street Overlay materials, specifically defining HMAC pavement as Level 3 Dense with PG 64-28 oil and requiring Job Mix Formula approval by the City of Pendleton in advance. Additionally, the Asphalt Pre-leveling specification is clarified to permit Level 2 or Level 3 HMAC in 3/8" or 1/2" Dense with PG 64-28 oil. Bid Item No. 11 for Asphalt Concrete Pre Level is specified at 150 tons with varying depth. All bidders must acknowledge receipt and acceptance of this addendum by signing and submitting it with their proposal; bids submitted without this acknowledgment may be considered informal.

The addendum clarifies that estimated quantities for Bid Items 11 and 12 (Asphalt Concrete) listed in the proposal were based on drawings provided in Section 14.00 of the bid documents, but measurement and payment will be based on actual quantities placed in the field rather than the estimated amounts. All work must comply with the latest version of Oregon Standard Specifications for Construction and meet workmanship and quality requirements as specified therein. The document requires bidder acknowledgment including company name, address, bidder name, signature, and title to be completed and returned with the proposal submission.
