Study On Theory And Method Of Building Total Information Management

Construction industry is an important material production sector of national economy. However, there are losses of information over the project lifecycle and information barriers among project participants and specialties because of backwardness of the method of information expression. Finally it leads to low efficiency of construction industry. So, it is very important and urgent using advanced IT technologies to promote the management of building project.Under the guidance of lifecycle management, omnibearing management and total factor management, integrating the key techniques of Project Information Portal (PIP), Building Information Modeling (BIM), Internet of Things (IOT), the frame system of Building Total Information Management (BTIM) has been established. The dissertation is organized as follows. First of all, the characteristics and contents of building project information management is analyzed in detail, and concept, content and functionality of Total Information Management of Building project are pointed, at the same time, the mechanism of realization of the project value is also discussed. Next, based on the analysis of BIM and IOT, the development path of BTIM is put forward. Finally, requirements, architecture and implementation approach of BTIM system of building project are investigated. The main innovation points in the dissertation are showed as follow.1. Under the guidance of lifecycle management, omnibearing management and Hall three dimension structure, introducing total factor management, integrating with techniques of PIP, BIM and IOT, the conception of BTIM is proposed. The Connotation of BTIM is also analyzed.2. The application routing of BIM and IOT in building project are put forward, then the growth steps of BTIM has been analyzed.3. The five-layer structure of the realization of BTIM system is put forward; the development method of BTIM system is put forward according to the structure.4. During the operation period of BTIM system, under the guidance of lean production theory and dynamic programming method, the running mechanisms of BTIM are summarized; The project value-added principle of BTIM is also analyzed according to the information theory.
