Development and Application Scenario of Municipal Utility Tunnel Facility Management Based on BIM, 3D Printer and IoT

In order to make the operation and maintenance phase of the utility tunnel more intelligent, this study is based on the building information modeling (BIM), 3D printing, IoT sensors, cloud computing and other technologies. The actual simulation of the utility tunnel in the operation stage. The results of the study learned that the use of the Internet of things and other technologies, will be able to more intelligent control of the use of the integrated management corridor, through cloud computing and other ways to reduce the advantages of cloud maintenance system set-up costs, increased efficiency in maintenance.
