Abstract: With the development of urban construction, the increase of project scale has brought about the problem of increasing management difficulty. By integrating the Revit, ArcGIS, CityGML, database and Web technology, this paper integrates BIM and GIS data to form City Geography Markup Language (CityGML) data, completes the database design of Engineering multi-source data, designs and develops an intelligent management system for urban engineering projects based on BIM and GIS.The system realizes project schedule management, quality management, engineering measurement and safety management.It can greatly simplify the management process, effectively improve the efficiency and quality of management, and save the cost of management.It can effectively solve the problems of poor information communication, time-consuming and inefficiency in the use of traditional management methods in engineering projects.
