Abstract: Taking certain station of Taiyuan Rail Transit Line 2 first phase engineering as an example, the application of 3D laser scanning technology in metro station civil construction completion delivery BIM model is elaborated. Workflow of point cloud model creation using the 3D laser scanning technology is expounded. The steps and methods of comparative analysis of point cloud model and BIM model based on construction drawing are proposed. The consistency between BIM delivery model and the site is achieved through application of 3D laser scanning technology, convenient for the highprecision installation of electrical equipment, providing data support for future longterm maintenance.
