High-resolution laser scan data for the new Block 4

The study area surveying creates high-resolution laser scan data from the HFT Stuttgart and provides the basis for the redesign of the HFT courtyard and the Block4

With the newly acquired high-end laser scanner Z+F Imager 5016, the surveying department records parts of the HFT Stuttgart buildings in 3D. The high-resolution measurement data can be used cooperatively in Faculties A, B and C. Part of the data has now been made available for the competition for the redesign of the HFT inner courtyard and new construction of Block 4.

No sooner had the old Block 4 in the inner courtyard been moved than work began on the new Block 4! With the newly acquired high-end laser scanner Z+F Imager 5016, the inner courtyard between Building1 and Building3 was captured in 3D by employees of the Surveying Department. The high-resolution laser scan data contain detailed information about the building geometry. They are the result of almost 20 scanning standpoints and thus also enable the derivation of dimensions and structures in concealed areas, for example from vehicles parked in the courtyard. With the high-resolution HDR images from the scanner camera, it was also possible to create a vivid coloured point cloud.

For some time now, the complete 3D acquisition of the building geometry has been carried out by parts of the HFT Stuttgart in the surveying department. As part of the competition for the redesign of the HFT-courtyard and the new Block 4 building, the measurement data of the courtyard was now made available to the students.

For the creation of as-built plans, sections and especially for modern 3D planning processes, such scan data are indispensable. Thanks to the high level of detail, the measurement data also meet the higher requirements in surveying and civil engineering and can be used, for example, as a basis for planning with the BIM method using a digital twin, or for the analysis of the building fabric. Prof. Dr.-Ing.  Austen from the Department of Geomatics and Prof. Dr.-Ing. Feirabend from the Department ofCivil Engineering are in cooperative contact in this context.
