Abstract: Method for constructing an elevator, more particularly an elevator that is used during the construction-time of the building, in which method the range of movement in the elevator hoistway of the elevator car of the elevator is changed in steps to extend higher in the elevator hoistway with stepped lifts of the supporting platform of the elevator car, and in which method the supporting platform is lifted higher in the elevator hoistway with hoisting means, and the support force needed for the lift is taken from the building via a support structure. In the method the supporting platform is moved in the longitudinal direction of the elevator hoistway while being supported on a support structure that is supported immovably on the building such that the point for taking support from the support structure moves upwards in connection with the lifting of the supporting platform.

Abstract: An arrangement and a method are provided for positioning the alignment plumb lines of the guide rails of an elevator, more particularly when installing an elevator during the construction phase of a building. The solution includes at least actuators fixed above the guide rails for moving at least the parts of the alignment plumb lines above the guide rails for positioning the alignment plumb lines.
