Abstract Industry foundation class (IFC) based building information modeling (BIM) systems has developed rapidly in recent years. However, there are still few methods and tools supporting web-oriented transmissions and queries of IFC model data. This paper describes a web-enabled IFC object model using the JSON format and the IFC data cache with the Redis distributed key-value store for IFC applications in web environment. Stepwise and dynamic parsing of the IFC data enables lightweight, standardized network data transmission with large-capacity, high-speed dynamic parsing of the IFC data. Tests show that the object model and the parsing method are able to support web BIM applications and significantly enhance the efficiency of parsing IFC data files, with double the parsing speed of large (over 30 MB) IFC files.
