Banner Casa Grande Medical Center will begin work on a $10 million Emergency department and Wound Clinic expansion this fall.

The expansion, part of an ongoing commitment to update the hospital, will add more than 3,300 square feet to the existing Emergency department, creating private triage areas and 12 more patient rooms to bring the total number of ED beds to 28.

The project will also put a second CT scanner in the ED, add more public restrooms, and expand staff storage and work space.

“As more people continue to move to our community, we want to make sure our Emergency department can handle their needs,’’ said Brian Kellar, CEO of Banner Casa Grande. “It’s our responsibility to make sure people have the best possible access to emergency medicine now and in the future.

“This expansion allows us to provide even greater access to emergency-care services.’’

The Banner Casa Grande Emergency department records more than 4,000 visits a month, making it the busiest ED in Pinal County.

The project’s first phase will move the current Wound Clinic to a more accessible space in the medical office building next to the hospital on Florence Boulevard. The second phase calls for the former clinic space to be remodeled into additional space for the Emergency department, Kellar said.

Planning and design have already begun with construction expected to be finished by November 2020.

Emergency services will not be affected by the construction, Kellar said. Parking and ED access will remain the same.

The ED expansion is the latest phase in Banner’s updates to the Casa Grande campus, Kellar said. Since 2014, Banner Health has invested millions in facility upgrades, including opening a new Women’s and Infant Services unit and expanding the hospital’s Pharmacy.
