Integrating BIM and IoT technology in environmental planning and protection of urban utility tunnel construction

This study integrated the building information model (BIM) and the Internet of Things (IoT) technology, planning the implementation plan of environmental protection of utility tunnel construction project, through information technology for utility tunnel project design, before construction, construction stage and other applications, the applications including: 1. Project site environmental dust monitoring and automatic sprinkler dust falling control system; 2.Based on real-time meteorological data site Environmental and temperature monitoring; 3. Based on BIM visual prototype system development. Finally, the application of BIM and IoT technology in urban utility tunnel construction and development environment and application benefits, as well as the follow-up development direction of recommendations.
