First, the existing elevator equipment had to be torn out and removed from the building, including a complete decommissioning and removal of elevator #1. Then, the elevators were upgraded with the latest in controller, motor, and drive technology for smart dispatching and vastly improved energy efficiency. Heavy duty buttons were utilized. The new car operating panel and emergency phone are easy to use and are placed much lower to the floor than the old style elevator button panel, ensuring access for individuals with limited mobility and for those using wheel chairs. Passing chimes and floor annunciators help passengers with visual impairment. The cab interiors were upgraded to high end textured cab panels and finishes.
