Objectives  Structural health dynamic monitoring is one of the most important jobs in the manage-ment and maintenance of key buildings, in which how to more effectively collecting, transferring, and mana-ging temporal monitoring data are difficult issues.

  Methods  A building information model corresponding to real-time and dynamic monitoring is presented, which realizes the merge of building information model (BIM)/reality 3D model and monitoring sensor network. Firstly, transferring and managing method and framework of the temporal-monitoring data of building are discussed and applied, in which the sensor data are aligned and packaged in temporal dimension in the lower computer. Then the transfer protocol based on JSON (JavaScript Object Notation), the data compression, and the re-organization method are introduced. In the upper computer, we relate database management methods of temporal sensor data. Finally, we use the audience hall of Nanjing Museum as a case study and develop a corresponding monitoring system. The feasibility and operation of the proposed method are validated and displayed in the case.

  Results  (1) The new building information model merges the BIM and reality 3D model, which suits the dynamic monitoring of the complex building. The BIM presents the detailed components (building inside) information as a base for monitoring the sensor network. And reality 3D model adjusts coordination information of BIM to geo-graphic location.(2)The framework of transferring sensor information includes an upper computer level, a lower computer level that can effectively collect and transfer monitoring information of complex building. Transfer protocol based on JSON working between upper computer level and lower computer level is exten-sible.(3)The temporal monitoring data with high speed and big volume have been significantly compressed and stored in the temporal database through the proposed management method.

  Conclusions  The integrated building information model, corresponding monitoring information transferring, and management method are useful to complex building monitoring. Currently, the system of the case just online shortly, more and more sensor data will be accumulated in the future and will be used to optimize and improve analysis methods.
