TOWARDS LINKING VIRTUAL MODELS WITH PHYSICAL OBJECTS IN CONSTRUCTION USING RFID - REVIEW OF ONTOLOGIES

Abstract: Virtual models have in recent years proven their worth in practice relating to building design. Today virtual models of the complete project are created before the project is carried out in practice. The immediate advantages of this are great; it introduces fewer errors, gives a better production basis, improved clarity and enhanced communication methods compared to traditional 2D drafting methods. However, there is still much unutilized potential in the virtual models, especially in the construction and operation phases. It is expected that a digital link between the virtual models and the physical objects in the construction process can improve the information and knowledge handling from design to construction, operation and maintenance. The link can be created by use by use of Radio Frequency Identification (RFID) technology. This paper describes a review and assessment of existing ontologies relevant in relation to creating this link. The ontologies are categorised according to their applicability to specify technical services, resources, organisational relations, business processes and overall frameworks for ontology descriptions and their relations. It is concluded that, with few modifications the technical service and resource ontologies are applicable for industrial use and the meta, organisational and business process ontologies needs further development and industrial maturity to be applicable.

User driven innovative building design

Abstract: During recent years there has been an ever-increasing focus on the possibilities to change the building process to raise quality on the final building products as well as on the activities of actors involved in the building process. One reason for this interest is the new opportunities evolving due to the broad introduction of advanced information and communication technology (ICT). VICMET is a general method for user involvement in every phase of the construction process and with a unique setup for each type of user. VICMET can use already created information in the building process and emphasis that the users are the key to next level of successful building projects. VICMET defines four spaces to support the activities in a innovative/creative design process; The Contextual Inquiry Space, the Conceptual Modeling and Game Space, the Functional Building Systems (FBS) Consolidation Space, and the Solution Space. In addition to these spaces there are supporting artifacts like Idea Bank and Good Story/Best Practice bank as well as Ontology containers and access to Communities of Practice and Interest. The project has so far validated the need for enhanced methods to involve end-users of buildings in a collaborative/participative creative and innovative building design process. The AEC professionals also appreciate development, enhancement and to some extent formalization of existing methods for user involvement in the building process.

FUTURE INTEGRATED DESIGN ENVIRONMENTS

Abstract: We are facing a probable great change in the way we carry through design in future ICT supported environments. The main driving forces are the digitalization of information handling leading to a paramount paradigm shift when information storage and access media are separated, building process and product systems are formalized in digital models, user environments are provided with rich multimedia access to virtual models, virtual collaboration rooms established, and new efficient and effective ICT tools defined and implemented.There are though some barriers putting strains on the development. Among the most important are missing ontologies both on business and Web/Internet service levels as well as their interrelations, poor user involvement in needs and requirements formulations on new ICT tools and continuous user involvement in design and evaluation of new user environments, and lack of interoperability within building process/product models. The general competence level and preparedness for organizational and work change due to global paradigm needs to be increased.The paper presents a system development approach to future development of Integrated Building Design Systems (IBDS) with efforts to specify needs and wishes on future system and resources to support system development. Examples are picked from ongoing global efforts as well as finished and ongoing research at Building Informatics, Aalborg University.
