As a surveying method, laser scanning was the optimal solution for obtaining exact plans as a basis for planning the refurbishment work. The fast and precise recording with a laser scanner significantly reduced the time and thus also the costs for the refurbishment work. The data obtained made it possible to precisely determine the effort and material requirements for all rehabilitation measures. Even the smallest deformations and irregularities were accurately recorded. The recording of the building with the 3D laser scanner FARO Photon 120/20 could be realized within two days. Thus, facades, floor plans, the supporting structure and much more could be captured. For further use, the laser scanner data was used in the CAD system with ArchiCAD. Thanks to PointCab Origins, the results could be easily read into the CAD system ArchiCAD. Within a very short time, floor plans, sections and facades were generated. PointCab Origins convinced with its ease of use and flawless functionality. The detailed results required a relatively short calculation time.
