During the repairing, rebuilding and extension process of the Yufo temple in Shanghai, BIM technologies, combined with 3D laser scanning and 3D GIS digital city technologies are adopted to ensure the practicability of the project in every phase and keep the close link and feedback mechanism among disciplines. In this project, great efforts are made to use BIM technology to provide precise visible models for every discipline during the building design phase, extend BIM technology to all the phases of the building lifecycle (construction, facility manage and maintenance), and create a integrated information model on the same platform. It is an innovative attempt on the application of BIM technology on historic building repairing, rebuilding and extension, combined with 3D laser scanning and 3D GIS digital city technologies.
