Building Information Model (BIM) was initially proposed by Autodesk in 2002. Currently, BIM has been widely recognized in the industry worldwide, baced on its great value. The concept of BIM has been gradually well-known in construction industry in China, and it’s a good prospect for development and application of BIM. But its application and promotion is still in start-up phase in China. It should be actively promoted in whole society. It was suggested in the paper: application and promotion of BIM technology should be implemented step by step, and precursed to apply in construction phase, ultimately achieved overall industrial application. This paper analyzed characteristics and advantages of application and promotion of BIM technology in construction phase, and discussed implementation sschemes and steps. Finally, it proposed BIM should be grandly guided to achieve comprehensive application in project’s whole-life.
