Abstract: Traditional digital 2D drawings, due to their own 2D attributes, are difficult to play a value in today's fine construction management. The rise of BIM technology, expands traditional 2D to 3D (Space), 4D (Time), and 5D (Cost). However, the impletation and value of BIM has always been controversial. This paper studies the application value of BIM through the implementation of specific projects. Specifically, new application are developed including model establishment, problem discovery of drawings, visualization, construction scheme simulation, deepening design and collision inspection, support and hanger design and hole reserve, and etc. The BIM technology is integrated with 5D platform, VR, UAV, and intelligent construction site in the project, to explore more possibilities of implementation of the BIM technology. The research and application results show that BIM has a great effect on the housing construction in producing great economic savings, in promoting the refinement and transparency of quality and safety management, and in bringing great improvement to the social image and social benefits of enterprises.
