1. A method for modernizing an elevator system, which the elevator system comprising a first elevator comprising a first car in a first hoistway, and a second elevator, comprising a second car in a second hoistway,
the method comprising the steps of:
using (the first using) the first and the second car for transporting passengers and/or goods between vertically displaced floors of a building, and thereafter
removing the first elevator car from use for transporting passengers and/or goods between vertically displaced floors, and thereafter
installing a construction time elevator into a lower end of the first hoistway, the traveling zone of the car of the construction time elevator covering only partially a height of the first hoistway; and thereafter
using (the second using) the car of the construction time elevator and the second car simultaneously for transporting passengers and/or goods between vertically displaced floors of the building, and thereafter
changing the traveling zone of the car of the construction time elevator to extend higher in the hoistway, and thereafter
using (third using) the car of the construction time elevator and the second car simultaneously for transporting passengers and/or goods between vertically displaced floors.
