Sun Health Foundation has broken ground on Banner Health Boswell Medical Center’s emergency department and tower expansion in Sun City, Ariz.

The new 40,000-square-foot, $106 million ED and six-story patient tower will serve as the hospital’s new main entrance and provide room for future growth.

The tower’s first floor, to open in late 2020, will include the main lobby, gift shop, retail pharmacy, admitting desk, and chapel. The five floors above the main lobby will remain shelled space, reserved for future inpatient rooms.

The project is being built by McCarthy Building Cos. and is being managed using Integrated Project Delivery. The architect on the project is HMC Architects. Major trade partners include Buehler & Buehler, Southland, Foothills Fire Protection, Schuff Steel, Cannon & Wendt, University Mechanical, Norris Design, and The Berg Group.
