Mayo Clinic is planning a major expansion to its Phoenix campus that will create a single-site, integrated Cancer Center. The $130 million new facility will add three additional floors and 217,200 sq ft of clinical and office space above the first level of Mayo Clinic's Proton Beam Therapy Building on Mayo Clinic’s Phoenix campus at 56th St. and Loop 101.
The Proton beam therapy building, previously announced as a $182-million project, broke ground in December 2011. That project is currently under construction by Scottsdale, Ariz.-based Hunt Construction Group, and was designed by the Minneapolis and Phoenix offices of AECOM, with engineering services supplied by Kimley-Horn & Associates, Phoenix, and HDR Engineering. Proton beam therapy is a precise form of cancer treatment that the Mayo Clinic claims gives greater control over radiation doses, using pencil-beam scanning.
