The towers have an advanced elevator system which attempts to minimise floor space whilst maximising the number of people they can transport. The main bank of elevators is located in the centre of each tower. All main elevators are double-decker with the lower deck of the elevator taking you to odd numbered floors and upper deck taking you to the even numbered floors. In order to access an even numbered floor from ground level, one is required to use an escalator to access the upper deck of the elevator.
