Co-ordination of Classifications for Product Modelling and Established Building Classifications

Computer based information management introduces new possibilities and puts partly new requirements on information and classification systems. The rapid develop-ment and dissemination of information technology within the construction sector demands international co-ordination of standards and classification systems. This paper presents the preliminary results of a study of the product model classification systems IFC and POSC/Caesar in relation to the established building classification systems as defined in ISO 12006-2 and the Swedish BSAB 96. The study is part of a project with the aim to analyse the structure, scope and direction of development for these different systems, and to investigate the possibilities of co-ordination and co-operation between them. It shows a need for co-ordination of concepts in the ontological and the domain
