Abstract: In recent years, the BIM (Building Information Model) technology has already become a key area of modern architecture research. However, there is lacking of analysis on the overall research of BIM in the current research reviews. Therefore, this paper studies 1664 journal literatures on BIM by applying the social network analysis, and makes a quantitative analysis of the current research hotspot, team and trend. In terms of literature statistics, the Journal of Information Technology in Civil Engineering and Architecture is the journal with the most relevant literatures published. In terms of research content, the design and construction management is the core of existing research, and the prefabricated building is an important research object. The research of BIM has been going deep into every stage of the whole life cycle of building over time. In terms of research team, the research team of Tsinghua University is the largest research team. Based on the analysis of existing research, this paper proposes five future development directions of BIM, which are strengthening management application, promoting intelligent construction, enhancing basic research, promoting technology integration, and innovating teaching mode, respectivly.
