From my reading of children's books that talk about things like this (yes, you read that right), often a smaller crane is installed on the roof, the larger crane pieces are brought up to the roof, and then lowered down on the outside. The smaller crane is then disassembled and taken down in the elevator.
As for the holes in the floor plate, I would assume that they would just drop in a replacement concrete plate, either pre-cast, or cast in place.
