The problem I see is that walking down stairs is pretty easy and most people can manage a number of floors without a problem. Walking up stairs is a different situation. Many people cannot walk up one or two levels, let alone the number of levels proposed. I think you would need tunnels from several levels going in several directions to escape platforms or safe rooms with elevator or crane access.
