Architecture PBL for designing and constructing on-campus facilities by technical college students using digital twins

This is the authors' abstract. We don't add key points for this paper.

In this study, we examined the role and issues of digital twins in architectural Problem Based Learning (PBL) for students, including not only design but also estimate and construction, based on actual cases. As an example, we examined three architectural PBLs-interior renovation and outdoor furniture installation-implemented on the campus of National Institute of Technology, Anan College from the 2020 to 2022 fiscal year. As a result, it was found that the expression of the architectural space, the safety of the construction, and the accuracy of the estimation were improved. An issue we found was that students could not get a realistic sense of scale only on Building Information Modeling (BIM), and it was important to actually perform construction with PBL.
