Abstract: This paper reviews the development of BIM technology and IFC standards, analyzes the importance of BIM technology in promoting the digital transformation of the construction industry. In addition, this paper introduces the current technical methods for automatically extracting MEP system information from BIM models and summarizes the main problems and challenges faced by these methods. Furthermore, the importance and research progress of automatically generating control programs based on BIM are analyzed. Based on the current status, this paper points out that the existing relevant research in building automation control field has not fully utilized BIM information, and suggests further developing more efficient information extraction technologies, automatic control program generation technologies and tools, to promote the deep application of BIM technology in the entire life cycle of buildings, to optimize the design, construction, operation and maintenance processes.
