Abstract

The present invention relates to a method for producing a tower segment of a concrete tower of a wind energy installation, comprising the steps: providing a segment mold having at least one formwork for defining a mold of the tower segment that is to be produced and for filling with concrete; filling the segment mold with concrete in order to form the tower segment by the subsequent hardening of the concrete; measuring the tower segment thus hardened for creating a three-dimensional, virtual actual model of said tower segment; producing said three-dimensional actual model; comparing the three-dimensional actual model with a predefined mold, in particular a stored three-dimensional, virtual target model; and determining a deviation between both virtual models and changing the segment mold, in particular changing the at least one formwork when the deviation exceeds a first predefined threshold value.
