CO-ORDINATION OF CLASSIFICATIONS FOR PRODUCT MODELLING AND ESTABLISHED BUILDING CLASSIFICATIONS Classification for product modelling

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
