In the master's thesis, we analysed the flatness of the concrete surface (floor) in the underground parking house in the newly built neighbourhood of Novo Brdo in Ljubljana. Based on the establishment of a geodetic network, we determined the coordinates of the control points, with the help of which we georeferenced the point clouds obtained by the terrestrial laser scanning method. Floor shape scanning was performed in two separate time measurements. In the first term measurement, we treated the floor as the surface of the concrete slab, and in the second term measurement, as the surface of the final concrete layer. According to DIN 18202, control of floor flatness was performed from point clouds. By comparing the floor point clouds, we analysed the differences between the unfinished and final state of the concrete surface. The results were presented graphically and the main numerical results were presented with various statistical measures. Finally, we presented our findings.
