Abstract: Based on a prefabricated residential project, this paper proposes the implementation plan and specific application path of BIM technology applied to prefabricated construction projects. Deepening design of precast components of BIM technology in the stage of prefabricated building design, optimization of pipeline collision, design of pipeline support and hanger and deepening application of vertical brickwork is discussed in this paper. It also studys the application value of BIM technology in the three-dimensional site layout, BIM5D construction simulation and visual project management in the production and construction stages. Through the comprehensive application of BIM technology in the design and construction stage, the construction efficiency and quality of prefabricated projects are improved, and the application of BIM technology in prefabricated projects can be used for reference.
