Safety Risk Management for Hoisting Construction of PrefabricatedBuildings Based on NB-IoT Technology

To study the safety risk of prefabricated construction hoisting process，this study analyze safety risk managementrequirements by identifying 21 risk influence factors in prefabricated components hoisting process in the perspective of interactivecoupling，to measure the weight of each risk factor based on the interaction matrix. The NB - IoT technology is introduced in theinformation management of prefabricated construction hoisting process. This study takes advantage of this technology andestablishes risk management system of prefabricated construction hoisting based on BIM and NB - IoT technology. The developedsystem realizes information management of prefabricated construction process and ensures assembly quality and efficiency, whichreduces resource consumption and improves the overall level of green construction management for prefabricated construction.
