Taking the shantytown reconstruction and public rental housing construction project of Longshan County in 2015 as an actual case, this paper studies the application of the BIM technology in the construction of high-rise buildings. Clarifying that the construction difficulties includes large quantities of divisional works, strict cost control of steel, difficult treatment of karst cave of bored cast-in-place pile, and etc., a 3D model is built to generate scene animation and to improve the visualization effect. During the process of project construction, BIM-based measures are taken to solve the shortcomings of extensive and experiential management in the process of construction management of traditional projects, including the 3D visualization, professional deepening design and design synthesis, scheme simulation and optimization, engineering quantity statistics, three control and three management, refined management of reinforcement, supervision, and etc. The project management data then realizes informatization, refinement, visualization, and risk predictability management mode, greatly improving the management innovation concept and production efficiency. At last, in response to the construction difficulties, the corresponding solutions are proposed to simulate the construction deployment and progress, and to innovate the construction method, as well as to deepen the whole process control of design collision inspection, reinforcement refinement construction and platform control, which facilitates the technical disclosure, scheme selection and construction preparation, and further improves the research and application of BIM.
