The emerging availability of numerous model-based design and analysis tools promises high interoperability in terms of data exchange, thus shorter planning cycles and higher design quality. However, seamless transfer of digital models across domains without significant data inconsistencies is still a major challenge in the practice. This paper aims to identify the procedural problems in the data transfer between architectural design and structural analysis and propose improvement.

This study reviewed the current data exchange practices, and concluded that data exchange based on the industry foundation classes (IFC) is the most spread in the research and software tools supporting architecture, engineering and construction industry. The study also analyzed the processes which affect the IFC-based data exchange. The interoperability of software tools through IFC files was tested in a comparative study. The testing results are reflected on the processes influencing data exchange, identifying the procedural problems and recommending the improvements.

Upon conducted analysis and testing, the authors propose the following strategies for the systematic improvement of the data exchange: (a) introducing interpretation rules in the data exchange standards; (b) focusing on multiple domain-specific building data schemas instead of on the integrated schema; and (c) developing a new certification process based on the domain-specific building data schema. The improvement proposal supported by the analysis provides a roadmap for the development of model-based exchange between architectural design and structural analysis.
