This paper discusses the platform structure and specific building steps of the OPERATION and maintenance management platform of Hutong Yangtze River Bridge project based on BIM technology. By studying the reasonable operation and maintenance management platform structure and function modules, it lays a scientific foundation for the information and intelligent maintenance of the bridge in the operation and maintenance stage. By studying the appropriate screening and integrate the data produced in different stages of the project, and these formats form are different data sources in need for a unified operational period of BIM model and the method of data, in order to improve the working efficiency of the operations management platform and management accuracy, reduce the risk of data loss, make the beneficial discussion.
