The application of building information modeling(BIM) technology in the construction industry in China has developed rapidly, and its further development is inseparable from the support of BIM standards. In view of the importance of BIM standards, it is necessary to review the existing researches on BIM standards. Firstly, three key research topics, namely theoretical research, technical research and application research of BIM standards, were determined by keyword cluster analysis method. Secondly, for each research topic, the methods and results of existing research were explained and summarized through critical review, with typical cases being enumerated. Then, the evolution trend of BIM standard research was analyzed by using the timeline map generated by keywords. The results indicate that the extension of industry foundation classes(IFC) standard and the technical and application research based on IFC will still be the research hotspots. At the same time, research on BIM standard framework will continue. Furthermore, future research on BIM standards should also focus on three cutting-edge areas: technological integration, expansion of application scenarios, and cross-disciplinary collaboration. The research results will help further develop BIM standards and improve the formulation and application level of BIM standards.
