The present invention relates to a method for virtual assembly of a structure, the structure being supposed to be assembled from a multitude of components on a construction site, the method comprising measuring, at a multitude of locations remote from the construction site, the components of the structure subsequent to their production and prior to their transport to the construction site, wherein the measuring comprises measuring at least the shape and size of connecting elements of each of the components, creating virtual representations of the components, virtually assembling the representations of the components, determining, based on assembly tolerances, whether the structure can be assembled with the measured components, and deciding, by means of an optimization algorithm, whether one or more components are to be reproduced, one or more components are to be reworked, and/or the structure is to be redesigned.
