With the rise of BIM, Building Information Modeling, technology it subverts process and method of traditional civil engineering industry.It brings different meanings and improve efficacy to each stage of building life cycle.Projects can get different kinds of benefits from BIM technology in plan, design, construction, and operation stages.Utility tunnel, designed according to the variety of pipes and cables, is built under traffic roads, which reduces the traffic impact during maintenance and repair.Establishment of utility tunnel increases urban sustainable development.Through BIM technology, thousands of drawings are turned into one model.Meanwhile, with real-time update, model will reflect the latest situation.When application extends into operation stage, model connected with site sensors becomes a completed database for operation.BIM facility management (FM), the new integrated method, can monitor and control utility tunnel to ensure steadily supply of water, electricity or gas.Further, it assists authorities to guard city safety.
