I may like skyscrapers, but I know little about their construction and have the following questions: When a tower crane is positioned inside of a building that is under construction and remains there until a building is topped out, how is it removed, and what becomes of all of the openings in the floor plates through which the tower crane extended? Do they become an elevator shaft? :?:
