Abstract: With the continuous improvement of the application level of BIM technology in bridge engineering, as well as the expansion of the application scope, the information standardization work is imminent. This paper analyzes the information classification and coding system of related industries at home and abroad, and divides the objects in the bridge engineering into 11 classification tables according to the characteristics of bridge engineering. An EBS coding structure form is also formulated. A classification and coding system suitable for bridge engineering information model needs is initially established, providing the basis for BIM model information transmission and project management.
