This paper firstly elaborates the difficulties of super-large bridge project management, as well as the status of the application of project controlling in the field of traffic engineering. Through the analysis of defects of project controlling mode in information collection, processing and analysis, as well as analysis of advantages of BIM technology application in the project controlling, a BIM-based project controlling mode is proposed, and a BIM-based project controlling platform is established. The overall structure of the platform consists of eight major functional modules, to achieve the implementation of BIM-based project controlling mode. At last, applications of the platform in the Wuhan Yangsigang Yangtze River Bridge project have achieved good results, which provides useful references for the BIM technology applications in the project controlling mode.
