Abstract：
This paper adopts research method of BIM modeling analysis, has conducted the research to BIM in complex applications, reached the following conclusions: BIM Technology Applied to the project design, construction and operation stages, to break the traditional the professional and the main body is independent of the working mode; BIM Technology can enhance the design scheme of three-dimensional sense of space and multi angle roof to the professional choice, the professional structure and other professional conflict is reduced to the minimum, and solve the drawing didn't found wrong leakage collision, intuitive display of pipeline space height and direction of the design.
