Development of the scenario-based evaluation of indoor circulation using BIM-enabled parameters

This paper aims to develop the scenario-based analysis of indoor circulation using BIM-enabled parameterized quantities of a circulation path computed by BIM-enabled applications such as walking distance, spatial topology, number of turns, etc. A building circulation plays an important factor to plan overall spatial configuration based on specific purposes so that it has been one of priorities even in the beginning of the design. As supported by Building Information Modeling (BIM) and its applications, a design review process has been conducted more efficiently and accurately by using computed quantitative circulation-related data, compared to the conventional process performed in manual. However, qualitative factors of building circulation such as efficient route have been excluded practically as a target of the BIM-based design evaluation. As motivated by such fundamentals, precedent research discusses design evaluation approach in a BIM environment focusing on qualitative circulation issues such as 'convenient access to a specific space'. Based on the research, this paper develop the scenario based evaluation framework in terms of a generalization of the evaluation process. Furthermore, the framework is demonstrated using a test model with specific scenario and circulation evaluationpurposed application implemented by the authors.
