Aiming at the problems of complex file format conversion, weak data interoperability and low effective information utilization rate in the development and application of industry foundation classes (IFC) standard documents, an implementation method of IFC model data mapping to database, reconstruction of building information model (BIM) on Web side and online visualization analysis of information was proposed. Based on Web framework, the application framework of IFC standard file to relational database was built. Using JavaScript language for deep parsing of IFC standard files, using Python language to store IFC model data and effective information throughout the entire lifecycle of buildings in a relational database. Combining practical cases and analysis, the implementation effect of this application framework was demonstrated and verified. The results show that this method can realize the integrity and high efficiency of project data interaction and support the secondary development of related applications in the whole life cycle of buildings. At the same time, intelligent construction technology and scientific management are integrated to improve the effectiveness of BIM information management and promote the digital development and intelligent application expansion of the construction industry.
