From Point Cloud to BIM to FEM and VAR for data management and visualization

The aim of this study is to investigate the efficiency and application of a conversion from Point Cloud-BIM Model to FEM-software and VAR to safety assessment for existing structure. With this information, the engineer can save time, also optimize the workflow and increase the accuracy of model. because engineers know which conversions can be properly executed and which data losses will occur during each conversion when a BIM-model is being transferred. The results did point cloud -BIM application is very useful for geometry investigation of existing building and BIM to FEM can be solve difficulty of creation most complex structure in FEM software. not support the expectations that using an IFC file format is the ideal manner to exchange information between BIM-software and FEM-software. If a direct link is available between two programs, this is still recommended. Even an intermediate file, developed to be used between two specific programs, had better results for most of the conversions than using an IFC file format. However, IFC is a file format that can be used as long as the engineer knows which data is imported correctly from the BIM-model.
