The Haidilao project is one of the cooperative projects series. The drawings have been completed and even the on-site construction is basically completed. Then a BIM model needs to be completed. Finally, the required model is completed. Since the drawings are already available, there is no need to deal with the content of the drawings, so it is completed relatively quickly.
In fact, the value of the model is not only for drawings. If the added information is integrated into a database that can be updated and used repeatedly, thus it will realize its greatest value.
