McCarthy Building Cos. recently topped out the $106-million emergency room and six-story patient tower project at Banner Boswell Medical Center in Sun City, Ariz. The 40,000-sq-ft ER, projected to open this fall, will increase its capacity to 56 beds from 42, with space to care for up to 60,000 ER patients annually. The tower’s first floor, set to open in early 2021, will contain the main lobby, gift shop, retail pharmacy, admitting desk and chapel. The five floors above the lobby will remain shell space, reserved for future inpatient rooms. The architect is HMC Architects.

The project is using prefabricated interior and exterior wall panels constructed off site and delivered to the jobsite for installation, saving nearly three months of construction time. A total of  770 prefab panels are being fitted to the outside of the buildings. Approximately 125 prefab interior wall panels also will be used on the project.

The Kitchell contracting team recently topped out the 551,750-sq-ft Catalina Parking Garage project at the Park Central Mall in Phoenix. The garage, designed by GLHN Architects & Engineers, is now the tallest precast parking structure in Arizona. Crews placed 11,700 cu yd of precast concrete to build the 10-floor structure. It will contain more than 2,000 parking spaces.

Kitchell also constructed the original Park Central Mall, which opened in 1957 as Arizona’s first regional shopping center. The area has been converted mostly to office space since then, but many of the mall’s original midcentury-modern buildings still exist and are being preserved and updated to create new office and retail spaces.
