Abstract: Efficient information interoperability is the core value of BIM. IFC standards promotes the research of the exchange and sharing of building information at different stages of life. Based on the characteristics of the construction industry and engineering information, IFC standards based scheme design of building electrical systems is proposed. By analyzing the information needs of different actors at the early stages of construction and the overall flow of the project, and according to IFC standards, the electrical system scheme design model is programmed. Meanwhile, the information structure of the process model is studied preliminarily. Scheme design allows project participants have a clear understanding of project information.
