Abstract: There are some problems of information loss, professional diversity, communication difficulties and low productivity in traditional rail transport project construction. These problems not only affect the construction progress, but also bring great difficulties to the management of the rail transport project operation and maintenance in the later period. The application of information means such as Internet of things and big data based on BIM technology is becoming an effective way to solve these problems. Taking the BIM application of Sanyang Road cross-river tunnel project in Wuhan as an example, through market research, data analysis, system development and other methods, the BIM project management framework system of rail transport project was studied. A BIM model with high granularity, high refinement degree and high field matching degree was established in a multi-stratification and multi-specialty way to meet the needs of 3D visual operation and maintenance management. Combining with the comprehensive perception ability of the whole system, the logical association between the operation and maintenance management modules was established. An intelligent operation and maintenance monitoring management platform based on BIM was developed to realize the 3D intelligent monitoring and display of the operating state of the equipment and facilities. The research results lay a foundation for the standardized application of BIM technology application in Wuhan rail transit engineering, and the whole life cycle process management of 3D visualization of the project was realized on the basis of the multiparty collaborative management platform, which effectively improved the project management level of the whole project.
