Taking BIM Applications in Lanzhou West Railway project for example, this article discussed some BIM Application such as construction process, engineering difficulties, solutions and specialized applications in the train station building, which could be reference for similar projects.By solving difficulties of this project, which included civil engineering calculation, secondary deepening steel roof truss design and construction hoisting simulation, level of specialized applications would be improved. BIM would played significant role in "Three Controls, Management and Coordination" and Green Construction.
