The addition included administrative, clinical, treatment and eye surgical operating rooms. To complete the expansion, two large traction elevator shafts were extended and a third was added. The operating rooms, front lobby and library were renovated in the existing facility. All operating rooms and other medical services continued while the construction was performed. The main HVAC system — a chilled water system tied to the campus heating and cooling loop — was built into a mechanical penthouse.
