Building Information Modelling (BIM) is a technology that can simulate all information in a development project into a three-dimensional (3D) model. In 3D map making, objects above and below the ground surface must be integrated in the same coordinate system in the BIM. BIM can be formed using point clouds data that are scanned using Terrestrial Laser Scanner (TLS). In this study, the object of observation is the exterior of the Institut Teknologi Bandung (ITB) Research and Innovation Center Building, the exterior of the ITB Central Library Building and ITB Tunnel. Scanning data processing through the stages of filtering, georeferencing and registration. Georeferencing using the direct georeferencing method in the UTM zone 48 South (S) projection coordinate system with orthometric height. Root Mean Square Error (RMSE) registration was analyzed with 7 mm registration error tolerance. Point clouds are modeled using BIM Revit software. The dimensions of model are validated using a tapeline. The exterior integration of the ITB Research and Innovation Center Building, the exterior of the ITB Central Library Building and the ITB Tunnel can be done by direct georeferencing and clouds to clouds registering. Validation result of model dimensions are smaller than the results of the field measurements using the tapeline. 3D modeling using BIM method produces a visualization of 3D solid buildings.
