About this file
This document package includes an addendum to construction drawings and a related federal contract opportunity notice.
The construction drawing addendum provides revisions to demolition plans, floor plans, and construction details for an MRI site preparation project at an Oklahoma City VA medical center. Key changes include revisions to walls in the MRI room and deletion of an RF window on the north wall. The project involves demolishing existing walls and windows to install a new MRI system, magnetic shielding, and RF shielding.
The federal contract opportunity is a presolicitation notice for the same MRI site preparation project. The solicitation will be posted on or after October 21, 2020, with a period of performance of 300 calendar days from notice to proceed. The estimated value is between $1-2 million. The opportunity is a Service-Disabled Veteran-Owned Small Business set-aside issued by the Department of Veterans Affairs Veterans Health Administration VISN 19. The scope involves demolishing and constructing a revised MRI suite and control room while keeping an adjacent MRI suite operational.
