||The development of the Industry Foundation Classes (IFC) started from the vision that an integrated building product model would cover all necessary information for a buildings’ entire lifecycle: from requirements management, through different design processes to construction and maintenance processes. Although the IFC model specification covers a substantial part of the required information, AEC projects still have encountered many problems putting this model into practice. AEC professionals still find it difficult to have dynamic, lossless, truly effective data flow amongst the different participants and applications. It is obvious that file based data exchange alone is not a feasible solution - some other solution for integrating project information is necessary. This workshop discusses some viewpoints and potential solutions to the above issues and problems.
