The standardized modeling, precision 3D entity and informatized construction management of tunnel should be realized. Hence, the overall structure of Guangfu Tunnel is subdivided based on Autodesk platform and the design drawings, so as to form a mature tunnel modeling rule naming system. And then the Civil 3D+Dynamo+Revit software interaction implementation system is adopted to achieve fine control of tunnel modeling; the BIM collaborative management platform, whose advantage is regarding the components of the Autodesk platform fine model as the information source, is used to manage the whole process of tunnel construction, and based on which, the allround management of project production, quality, safety, design and data is proposed. Finally, the model, data, approval information and other contents are interrelated to achieve the closure of engineering data.
