AB - Projects with storage constraints face issues like unclear material locations, excessive materials shifting, and poor waste handling. Although the 5S concept is not new in the Lean Construction movement, it is not easy to implement on-site. This paper aims to explore the integration of 5S-based storage planning with the visual medium of BIM, which can make it more embedded in the site process. The process follows three steps: using 5S to plan the storage locations, converting the 5S plan into BIM, and finally visualizing the plan on-site using paper media and visual aids. In this paper, BIM was used as a visual management tool, not for automating or managing inventories. The findings suggest improved material flow clarity, reduced unnecessary movement, and better identification of reusable waste materials. The study demonstrates that effective Lean implementation can be achieved through simple planning decisions reinforced by visual tools that connect digital models with physical site practices.
