Abstract :Â The skyscrapers of the 21st century are born, but the height is proportional to the difficulty of construction. The higher and the more complex, the more bizarre the ultra-tall buildings are, the more difficult the construction will make the construction site safety becomes uncontrollable. How can the maximum elimination
of construction safety hazards?BIM technology offers a wide range of options for a wide range of engineering managers because of its advantages of simulation, predictability, dynamics, and monitoring, which can greatly reduce the probability
of danger. This paper discusses the application of BIM technology in multidimensional space planning, safety guidance transparency, site danger prevention and isolation, virtual demonstration and simulation field,cloud safety inspection and risk location and prevention. The probability of occurrence of accidents, but also improve the efficiency of management staff.
