  1. Common concepts for naming and definition in AEC (Lexicon) The development of common concepts for naming and defining construction terms for international use and in multiple languages starting with Dutch, English, German, Norwegian and French. STABU have also developed tools for collecting and manipulating definitions. Moving IFC product models into use CONCUR has contributed to the the development of IFCs and provided criticism to the developers. The major contribution was in the area of document metadata. The project partners have provided a test bed for trialling the advanced use of IFCs with industrial information. CONCUR has demonstrated early applications of IFC v1.5.1 and IFCv2.0 CAD system translators for IFCs have been tested and feedback has been provided to software vendors. Encouraging software vendors IFCs were originally intended for exchanging information. CONCUR has show that they can also be used for storage. CONCUR has shown how IFCs can be used in in STEP (Express) object databases for both storage and manipulation (Model Merging). The partners showed how XML could be used to interface with models in a STEP database. This showed that models can be used without the need for sophisticated modelling systems. (none CAD tools) The partners developed a prototype IFC/Browser for viewing and extracting information from IFC models. (a none CAD tool) Technical Issues IFCs and their translators are still immature and are very limited in their application. Serious general commercial exploitation is unlikely to happen before 2004. There is a need for funding to develop the depth and breadth of the models, especially in the product area. Currently cost and time are not being supported by vendors. There is a need for JAVA 3D development for viewing to replace the limited VRML. The modelling technology needs to keep pace with XML developments so that IFCs can be integrated with eCommerce applications Technical adoption Vendor uptake and translator production is at least 9 months behind model development. Different vendors are using different versions of IFC which leads to incompatiblity There is an increasing vendor interest in IFCs, especially from the smaller vendors.
