Prefabricated components, as the basic unit of prefabricated buildings, play a decisive role in the quality and cost of the building. At present, the data format and information storage mode of the component model are diversified, which causes the project information to be effectively shared and exchanged, and the phenomenon of information islands is formed. Aiming at this problem, this paper proposes the construction scheme of BIM-based modular building parameterized component library through the comprehensive application of IFC standard and information integration technology, and verifies the component model information extension and component library construction scheme based on IFC standard through examples. Feasibility, providing a reference for standardizing and unifying BIM software data standards.
