This document is Addendum No. 3 issued by the City of Pendleton for the UAS Flex Hangar 3 Project 2025, dated March 28, 2025, with a bid opening scheduled for April 3, 2025 at 2:00 p.m. The addendum modifies the project plans and specifications and consists of eight substantive changes affecting various construction elements. Key modifications include allowances for metal stud framing design to reference SSMA span tables for sizing; permission to use fiberglass insulation in lieu of mineral fiber for sound insulation if thickness adjustments maintain equivalent sound absorption properties; additions to the approved subcontractor list in Section 13122; revisions to data outlet specifications requiring CAT 6 cables and conduit; specification of an oil-water separator model (Striem os-35 with clean sweep coalescing material or approved equal); addition of wall type 7 symbol to the north wall of Mech 300; clarification that mezzanine structures may be provided as integral with the metal building shell or as separate structures at the bidder's option; and notes clarifying that wall type 7 terminates at interior faces of exterior metal siding and roofing metal. The addendum emphasizes that these bid drawings are diagrammatic and do not limit structural system options, with bidders responsible for providing detailed structural drawings and calculations. All bidders must acknowledge receipt and acceptance of this addendum by signing and submitting it with their proposal; bids submitted without signed acknowledgment may be deemed informal.
The addendum contains no information regarding pricing, set-asides, incumbents, funding requirements, or contract terms, as it functions solely as a technical modification document to the project specifications and drawings. All changes are binding modifications that offset only the specific portions of plans and specifications mentioned, with the remainder of the contract documents remaining in full force and effect. It is the responsibility of all bidders to ensure compliance with the addendum requirements.
