Proposal for an automatic process for geometric control: Using the point cloud from the 3D laser scanner and the digital model of a BIM project

The approach proposed in this work firstly enables the BIM model to be checked and georeferenced with the local site execution coordination system. In fact, two complementary solutions were proposed as part of our professional thesis: (1) a Cloud Solution: Cintoo Cloud, which enables advanced visual control with mapping of implementation discrepancies between point clouds and the BIM model. Discrepancy report files can be shared in real time via email or collaborative BIM platforms (BIM Track, BIM 360, etc.) in .BCF format. The Cintoo Cloud solution enables annotations to be shared in real time with stakeholders, and a PDF report of all annotations and comments. (2) a Desktop Cyclone 3DR solution offering a host of functions for comparing BIM models with the point cloud generated by a 3D terrestrial laser scanner. This solution generates an inspection report, in PDF format, presenting a clear mapping of tolerable and out-of-tolerance deviations, with statistics on deviations.
