IFC-Based Computational Support Tool for Managing and Using Design Planning Information: Case Application and Evaluation

The design process in architecture includes sequential workflows such as planning, feasibility study, schematic design, design development, and construction document phase. The design process depends on design information generated through cooperation after the initial phases of design. As design information generated during the initial phases of a project is interpreted during later phases, errors committed during the initial phase are constantly discovered. Consequently, incorrect initial design information may constitute a significant problem that reduces the quality of design products generated during the life cycle of buildings; in particular, planning information such as design objectives, requirements, and constraint conditions has a significant influence on subsequent phases of the design process. Therefore, it is important that design projects allow for collaboration and adjustment by participants in their initial phases. Moreover, the planning information should be continuously shared, managed, and used during the design process. However, general projects in design offices remain time-consuming and laborious. Problems that arise in design projects include the following.
