-The intersection of Jakarta – Supratman street is one example of an intersection in the city of Bandung that experiences traffic jams. So that the role of road infrastructure can be following the role of roads in Article 5 paragraph (1) of Law Number 38 of 2004, flyovers were built. See the importance of flyover construction, it needs a document that can provide information related to the flyover in the form of a final drawing after the construction process is complete. As-built drawings is a document containing drawings made by the conditions built in the field. The result of this research is to make a 3D model and as-built drawing from the 3D model before. After that, validation of geometrics is done towards the acquisition result and 3D model from the Jakarta-Supratman flyover. In the modelling of the Jakarta-Supratman flyover, the data used is the result of data acquisition using TLS. The data will be processed with the stages of the registration process, georeferencing process, deletion of unused point cloud (filtering), and the modelling process. The average value of registration errors is 0.000 meters. The results of the three-dimensional model are used as a reference in making as-built drawings in plans, visualizations, and bridge sections. Three-dimensional models are displayed with the level of detail used level of detail two by adding supporting objects that match the actual conditions. Geometry validation results show data differences between 3D models, point clouds, and model plans. The geometry validation value is obtained from the difference in the size of the data model with the planning model in Detail Engineering Design of 0.118 meters and for point cloud to the real world object of 0.009 meters.
