Abstract:Theoretical research shows that the application can achieve the best implementation effect of BIM in the full life circle of engineering construction. However, the application of BIM in municipal engineering is still limited to the practice of individual stages, and there are many obstacles in its promotion. The development and application status of BIM in local municipal engineering industry are analyzed, and the obstacles and related factors faced in the stages are sorted out. And then the importance of each factor is determined by DEMATEL method. Finally, the relevant countermeasures are proposed for the promotion of BIM Technology in municipal engineering.
