HMC Architects and McCarthy Building Companies celebrated the topping out for a new $106 million emergency department (ED) and patient tower at Banner Boswell Medical Center in Sun City, Ariz.

Members of Banner Boswell, McCarthy, Sun Health and HMC were on hand to sign a ceremonial beam, which was lifted into place at the top of the structure. The new 322,000-square-foot expansion, which includes a new ED and six-story tower designed for 192 beds to accommodate patient needs, is being supported by the community through donations to Sun Health Foundation and is slated to open this fall.

“We are thrilled to celebrate this milestone with our collaborative partners,” said HMC Architects’ Managing Principal Matt Lafflam. “By utilizing an Integrated Lean Project Delivery (ILPD) construction method and incorporating prefabricated building elements, we were able to reduce costs and save in construction time.”

Committed to the success of the project through robust collaboration and innovation, the ILPD construction method consists of McCarthy Builders and HMC—in a standard CMAR contract—co-located at the hospital with trade partners Southland Industries, Buehler Engineering, University Mechanical & Engineering Contractors (UMEC), Cannon and Wendt, and The Berg Group.
