Abstract:The essence of the application of BIM technology in municipal road and bridge engineering is "cooperation". Based on the principle of BIM technology as practical guidance for construction, the innovation and application of BIM technology in the implementation of municipal reconstruction engineering are introduced by many projects. According to the intelligentization, refinement and informatization as the direction, in order to provide the services for the municipal engineering management, the feasible and effective guidance for construction and intelligent control will become an important power of engineering management innovation and help the upgrade of enterprises in the engineering management.
