In recent years, the application and popularization of BIM (Building Information Modeling) technology have been severely limited by information island issue, which is resulted for complex problems, such as the design and construction separation, modeling repetition, lacking of overall life cycle management, etc. For the reasons above, combing with examples of project development, this paper proposed a BIM-based construction information management platform collecting all data of the BIM models during the whole management period. The construction of the platform involves the application of BIM modeling technology, computer programming technology, internet technology, and etc. On this platform, the information-island problem can be solved, and real-time collaboration of BIM technology can be realized in the construction stage. Moreover, this paper provides an idea of new method for the BIM development and application.
