Now that this bldg is nearing occupation it time to make some corrections.
Per the NYC DoB the Epic is recorded to be ~196.3m (642ft) and 59 floors.
The COO also shows that there is a 60 and 61 floor that contain mechanicals and the elevator room. I leave it to you as to what floor count should be.
Per NYC DOB here is link to the COO for the Epic:
