As one of the main modes of mass transit in the urban area, urban rail transit is of great significance to relieve the traffic pressure caused by urban expansion. The visualization, professional cooperation, data generation and automatic mapping characteristics of Building Information Modeling (BIM) provide strong support for the innovation of urban rail transit design and construction management process. By introducing the application of BIM technology in Shuangdun Station of Wuhan Rail Transit Line 12 in the preliminary design stage, the six modules of plan comparison and selection, visual design, three-dimensional structure calculation, collision inspection, engineering quantity statistics and automatic drawing are summarized and analyzed, It will provide references for the BIM technology application of metro station in the preliminary design stage.
