Steel structure engineering is widely used in the modern construction industry with its unique advantages.However,there are still many challenges in the process of construction management of steel structure projects,such as difficulties in coordinating design and construction,complex construction organization and progress control,and great pressure on quality and safety management.Based on the difficulty of analyzing the difficulties of steel structure project,this paper discusses the application of BIM technology in the design of steel structure,construction simulation and schedule control,quality and safety management and engineering information management,and proposes to strengthen BIM talent training,improve BIM standard and specification,promote the integration of BIM and other information technology,in order to provide reference for the application of BIM technology in the collaborative management of steel structure engineering construction.
