Answer 1

Answer:

Of course, there is also the inconvenient fact that lift systems are not designed to go all the way up 108 floors. They are also often split to service 20–30 floors at a time depending on traffic. One set of lifts could service 1–20 while another could start at 1 and go to 21–40.. Then a completely different set of lifts will be needed to go up more floors
