Abstract: In order to promote the application exploration of BIM technology in the forward design and second detailed design for pipeline colligate of the subway stations, this paper carries out the research on the optimization for its construction drawing based on BIM technology. Through analyzing problems existing in the expression of the construction drawings of the subway station pipeline colligate design, this paper performed a critical study on its multi-cross section. The results showed that BIM-based application research on multi-Cross Section Drawing can significantly tackle complex expression elements, low efficiency of section drawing, and difficulty in recognizing drawings existing in traditional two-dimensional pipeline comprehensive construction drawings, etc. Based on the interaction of 2D & 3D and visualization of BIM technology, it can automatically generate multi-section M & E drawings with annotations by using pipeline colligate cross section tool. This paper illustrated design elements of horizontal layout drawing by multi-section drawing of the pipeline colligate, which made the expression of the horizontal layout drawing more clearly and centralized the data of design. Hence, the quality, value and data for design of the pipeline colligate drawing can be significantly improved.
