Abstract：
Based on the three dimension digital technology, Building Information Model integrates various detailed information of the engineering project. By Building information model, the digital technology is directly applied to construction project. On the basis of a large number of literature about the research of BIM, the promotion、research and application status about BIM are summarized; Combining the domestic major engineering, the specific application of BIM in actual construction project is introduced. Finally specific to the existing problems in development and promotion of BIM technology, suggestions are proposed to promote the implementation of BIM, which provides important reference for further application of BIM technology in construction industry.
