The regional track structure of the beam-end telescopic adjuster on the long-span bridges and the rail-lifting device at the beam joint is prone to disease. Through the in-depth discussion and research on the application of Building Information Model (BIM) technology in the high-speed railway rails telescopic regulator project, combining the regulator health monitoring with BIM technology, a BIM-based regulator monitoring method was proposed. It uses edge computing to preprocess the data, adopts a hierarchical design, combines each functional domain with each layer of BIM in parallel. It establishes a universal security chain association model, and it conducts chain domain and global domain analysis of the data. On this basis, according to the Construction Operations Building Information Exchange (COBie) standard, an as-built delivery information model is established to integrate and transfer data. It seamlessly transfers the construction and management process information about the rail telescopic regulator and BIM to the operation and maintenance stages. In this way, the real-time assessment and early warning of the rail telescopic regulator and the coordinated management of intelligent decision-making are realized, laying a foundation for future intelligent operation and maintenance.
