Abstract: This paper is based on the research of BIM mainstream standard IFC (industrial foundation
classes), which has been developing rapidly in recent years. According to the data sharing
requirement of prefabricated components, the production information organization and expression
mode of prefabricated components are studied. In accordance with the IFC standard, this paper
divides the information of the prefabricated components in the production stage into product
information, process information, resource information, cost information and site information, and
establishes the information model of prefabricated components based on IFC standard. Finally, this
paper gives a concrete example of applying the information model of prefabricated components. The
result shows that the information model can effectively improve the management of data information
and the cooperative production efficiency.
