Building Information Modeling, which was applied mainly in the construction sector, is expanding to the road sector, and the government recently recommends preparing individual application guidelines considering the characteristics of detailed fields such as railways, ports, and complexes through BIM implementation guidelines. Compared to general construction projects, a lot of the works such as signals, electricity, and power, and the railway BIM 2030 roadmap has been presented to apply BIM to railway construction projects that require business consultation and work environment review with various local governments, and pilot projects are in operation. Unlike a general building, in which the construction begins after the detailed design is completed, in the railway project, the detailed design of other works proceeds along with the roadbed construction. Because construction and design work together, railways need to coordinate detailed engineering interfaces such as trajectories, signals, and power, and the application of BIM in design interface coordination has the advantage of maximizing the effectiveness of pre-review. Overseas railway construction projects actively used BIM to adjust design interfaces and had a collaboration process to modify BIM models and create construction details from the revised models through regular meetings with suppliers. Therefore, this study aims to derive the factors necessary for establishing a BIM collaboration environment based on a survey of practitioners as a preliminary step for establishing the BIM collaboration process of the railway construction project.
