This design adopts digital BMI (Building Information Model). Equipped with a cloud operation and maintenance system based on 5G technology and the IoT as well as various internal cleaning facilities and safety devices, it provides more comfort to people answering the call of nature. Each building unit is prefabricated in the factory and assembled on the scene, thus realizing only a 3-4-hour construction process, which effectively reduces the damage to the surrounding environment and creates an intelligent and low-cost infrastructure solution for building a smart city.
