Install bracket is based on air conditioning of buildings, drainage, strong and weak electricity system, due to the involved system, the complex pipeline, design drawings information not fully, and bracket installed on building the main structure of the strong dependence, subsequent installation when increase the difficulty of installation, waste installation space. Using BIM Technology are effectively integrated with the deepening of the design, in advance of the electromechanical system simulation installation and solve the difficulties in construction, pipeline and the scaffold material saving, increase the building height, the collision detection of the pipeline. Visualization of the collaborative design changes, is conducive to the professional for further deepening of the design, construction procedure is simplified, more conducive to the construction site management and shorten the construction period, thereby saving cost. This paper uses BIM technology to support the installation, design and construction of the integrated optimization, visual simulation are described.
