The Haskell Co. of Dallas completed construction on St. John Broken Arrow Hospital and its accompanying medical office building and medical campus in Broken Arrow, Okla., marking the largest design-build health-care project in the company’s 45-year history.

The $100-million general acute-care medical surgical hospital opened in fall and includes an emergency department, eight-room surgery suite, radiology and the Tulsa Bone & Joint Associates orthopedic center.

The hospital includes a six-story building with a seventh story penthouse.
