In this paper, we seek to define the path object and its properties as an instance level of a circulation path between two spaces. We further suggest the practical application of path objects in design review issues using numeric data on building circulation (NDBC) as a complete collection of circulation paths from a given Building Information Modeling (BIM) model. As the use of BIM is increasingly being implemented in architecture, engineering, and construction industries, rich data related to building objects and useful digital representations have been developed for specific circulation review tasks. Among the several benefits observed from such applications, this paper focuses on the BIM-enabled formal definition of the path object and its properties. We further demonstrate the use of several analysis applications using the NDBC. Due to the rich spatial information defined in a BIM model, path objects can be instantiated dynamically, and a specific data model for building circulation paths can be defined with a series of numeric data sets. In this paper, the formal definition of a path object and its properties are explored, and one of its NDBC applications is clarified and demonstrated for further circulation analysis tasks using a software tool developed by us.
