With the development and popularity of BIM (building information model), the application of 3D information models in the municipal engineering entire life cycle is gradually becoming the focus in the field of the operation and maintenance of engineering. This paper deeply analyzes the application prospect of the operation and maintenance system for an urban utility tunnel, while discussing the system's operation structure and major function. Through a practical engineering case, the research team uses the core technique to realize "separation" and "interlinkage" between component block and parameter information, and it shows the technique route from the BIM completion model to the visual tunnel operation and maintenance system completely. The research results provide a reliable basis for the construction and the application of intelligent public municipal construction management system, which is designed based on the interdisciplinary concept of art design and architecture science.
