I know there were probably several elevators in the buildings and they all could have been placed at the same time.
Most elevators are built in the center of the structual supports of a building and there is plenty of space between the elevator and shaft walls to put whatever you would need. I know, I've built many.
It was also the largest elevator upgrade project in history as indicated by architectural digests/mags.
