Abstract: There are many professional units involved in the construction of tunnel engineering, and the management is complicated. The construction information has the characteristics of sporadic, scattered and independent distribution, which causes the phenomenon of inability of engineering data interoperability, data islands and difficulties in data exchange, which increases the risk for engineering construction management. In order to solve the above problems, the concept of CIM (Urban Information Model) based on the integration of BIM (Building Information Model), GIS (Geographic Information System), and IOT (Internet of Things) is applied, and the project is constructed by building an information management and control platform for the project. The engineering information complex of the three-dimensional digital space achieves the goal of refined, dynamic, digital, and visualized engineering construction management, improving the level of scientific management and decision-making in engineering construction, and reduces the risk of engineering construction management.
