Research On BIM Collaborative Design System Of Urban Rail Transit Based On Revit And Unified Data Model

The design of urban rail transit projects involves a wide range of fields and complex roles for participation,which makes coordination between various disciplines difficult,resulting in low design efficiency.The application of BIM technology to realize industry information management and achieve a highly standardized management and multi-discipline comprehensive coordination to the success or failure of the project It is of great significance.The existing BIM collaborative design system only realizes part of the collaborative functions of the 3D model,and cannot yet meet the full life cycle requirements of actual projects.In order to realize the multi-discipline and all-round collaboration function,the BIM collaborative design system based on Revit and unified data model is studied to improve the efficiency of collaborative design among multiple disciplines.In the research process,we sort out the information requirements of various disciplines,clarify the collaborative data between disciplines,and extract the required information in a targeted manner to improve design efficiency.At the same time,the unique code is used to bind the component in the design model with the component stage attributes,and add stage attributes to it to ensure the full life cycle management of the component.Adopt Revit design software,My SQL database,Fast DFS file server as the main body to build a unified data model urban rail transit BIM collaborative design system.Among them,Revit provides data source support for system operation,My SQL database provides structured data storage support for the system,and Fast DFS file server provides unstructured data storage support for the system.Designers use this system to realize the sharing of graphical data and structured data in the design process,deepen model document-level management to model component-level and attribute-level management,and realize the data association between structured data and 3D model information to ensure The consistency and completeness of data can effectively improve the interaction efficiency between data,the design accuracy of professionals,and the collaboration efficiency between professional designers,promote the efficient and orderly completion of design work,and reduce the workload of reviewers and management personnel.By testing the related functions and performance of the system,the system can solve the problems of influential professional design interaction and insufficient efficiency in urban rail transit engineering projects,reduce design changes,and improve overall design efficiency.
