Design and optimization of prefabricated building system based on BIM technology

The popularization and maturity of BIM technology provide a new method and platform for the realization of collaborative design of prefabricated buildings. At present, BIM applications in prefabricated buildings are mostly stays in the stage of construction and production. Prefabricated buildings are the best choice for the transformation and upgrading of construction industry because of their high efficiency and small impact on the environment. Prefabricated building is not only a building form, but also a complex system engineering, which needs to use the methods and ideas of system engineering to solve practical problems. In order to promote the application of BIM in prefabricated building design, this paper compares BIM collaborative design with traditional design methods. Based on the requirements of BIM technology IDM, a conceptual model of PCP collaborative design is established to determine the accuracy of BIM model in different design stages. Parametric design tools dynamo and structural precast for revit were used to split prefabricated components, configure steel bars and analyze the structure of prefabricated buildings. The results show that the effectiveness of the building collaborative design method based on BIM is verified through an example.

Automated summary

The popularization and maturity of BIM technology have provided a new method and platform for the realization of collaborative design in prefabricated buildings, leading to more efficient transformation and upgrading in the construction industry.
