The Aerospace Center was constructed to support Collins Aerospace growth in the industry. The facility houses testing and research components. The site consists of two structures, separated by an expansion joint. The Office building is two-stories and was constructed using steel framing and composite floors. Large curtainwall systems are provided at the primary and secondary entrances to enhance the natural light into the lobbies, as well as the corporate break room. A custom truss spanning approximately 75 feet supports the curtainwall at the secondary entrance. The warehouse facility is constructed using load bearing tilt wall panels, supporting steel framing and decking at the roof. The tilt walls match the height of the two-story office building. The warehouse includes areas of elevated mezzanines. The mezzanines would support various vibration sensitive equipment. Additionally, the site soil conditions were varied and required of a ground improvement system, rammed aggregate piers.
