About this file
This document provides details for a federal construction contract opportunity to alter an F-35 aircraft hangar at Truax Field Air National Guard Base in Madison, Wisconsin. The project seeks to demolish nearly 20,000 square feet of existing hangar shop space and reconfigure the area for F-35 aircraft maintenance operations, including new lavatories, office space, break rooms, and repair shops. An additional nearly 20,000 square feet of existing hangar space will be modified to accommodate F-35 aircraft, including modifications to the high expansion foam fire suppression system, aircraft make-up power and air systems, and lightning protection. The solicitation will result in a single construction contract award for both demolition and new construction work, with two optional line items. The pre-bid conference is scheduled for February 16, 2021, with bids due by March 8, 2021. The contract duration is 365 days from notice to proceed. The NAICS code is 236220 and the magnitude is estimated between $10-25 million.
