The document, titled "Addendum #1 to B9 & B12 Hinge Pin Assembly Repair B27496," outlines the construction services required for the replacement and upgrading of hydraulic door hinges B7, B8, B13, and B14 at Kirtland Air Force Base, New Mexico. The primary objective is to enhance the performance and durability of these hinges, ensuring they can withstand repetitive motion and thereby prevent premature wear and failure. The contractor must demonstrate at least ten years of relevant experience and provide comprehensive turnkey services, including labor, materials, and installation. The project demands careful coordination with Kirtland AFB's Civil Engineering department to minimize disruption to ongoing operations, requiring a staging and access plan, as well as adherence to various regulatory standards. Scheduled timelines for phases of the project, from submission of drawings to completion, are explicitly defined, totaling 321 days. The contractor must ensure compliance with all federal, state, and local regulations and is responsible for delivering all necessary permits before commencing work. Post-construction requirements include warranties, operations manuals, and as-built drawings to ensure successful project completion. Overall, this addendum emphasizes the critical nature of operational readiness and facility security throughout the hinge replacement project.
