1. A method for erecting a final elevator installation in an elevator shaft of a building, the method comprising the steps of:
installing a construction phase elevator system in the elevator shaft for use during a construction phase of the building while the elevator shaft becomes higher with increasing building height, the construction phase elevator system including a self-propelled construction phase elevator car, and adapting a usable lifting height of the construction phase elevator car to an increasing height of the elevator shaft;
installing at least one guide rail strand in the elevator shaft for guiding the construction phase elevator car along a travel path in the elevator shaft;
assembling a drive system for driving the construction phase elevator car, the drive system including a primary part attached to the construction phase elevator car and a secondary part attached in the elevator shaft along the travel path;
extending the at least one guide rail strand and the secondary part of the drive system upward in the elevator shaft during the construction phase in accordance with the increasing elevator shaft height, wherein the construction phase elevator car is adapted to be used both for transporting persons and/or material for construction of the building and as a passenger and freight elevator for floors already used as residential or business premises during the construction phase of the building;
after the elevator shaft has reached a predetermined final height, removing the construction phase elevator system from the elevator shaft and installing a final elevator system in the elevator shaft which final elevator system is modified compared to the construction phase elevator system; and
wherein the final elevator system has an elevator car with a drive system that is modified compared to the drive system of the construction phase elevator car.
