Research on BIM-Based Assembly Sequence Planning of Prefabricated Buildings

Prefabricated buildings bring a new problem called assembly sequence planning to the construction industry. This problem is becoming more prominent, and is haunting related enterprises. This paper uses literature method and expert consultation method to study the problem related to assembly sequence planning of prefabricated buildings, and then combines building information modeling (BIM) with process engineer experience to propose a BIM-based assembly sequence planning method. The method can assist process engineers to make some reasonable assembly sequence schemes of a prefabricated building from the perspective of visualization. A precast concrete building model is used to illustrate the working process of this method, and the result shows that the method is good for the assembly sequence planning of prefabricated buildings.
