REQUIREMENTS ON 3D BUILDING INFORMATION MODELS AND ELECTRONIC COMMUNICATION EXPERIENCES FROM AN ARCHITECTURAL COMPETITION

Abstract:In 2007 the public clients in Denmark started implementing new requirements on information handling in their construction projects. In the full implementation they will demand that all construction data on public construction projects are digitally managed and interchanged. Tendering shall be effected electronically over the Internet. Design will be based on 3D building models, which are gradually specified to reach different levels of detail. The parties involved in a specific construction project must share and interchange data and documents about the construction project on a common document management system accessed through the Internet. When a construction project is finished, the parties will hand over relevant operation and maintenance data electronically to the client. Detailed requirements have been developed on behalf of the public clients within four main areas: 3D models, Digital Tendering, Project Webs and Digital Handover. Within each of these areas, initial requirements have been tested in specific construction projects. This paper describes experiences from the test of the suggested requirements on 3D models. The requirements were used in an architectural competition on modernizing a cluster of university buildings. Four selected architects were invited to the competition. The proposals from the architects should be prepared as a 3D model in IFC format supplemented with a number of 3D visualizations chosen by the individual architects.
