Qualitative Evaluation of 5S Application Considering the Experience of Electrical Construction Experts

The 5S lean tool is one of the most common lean construction techniques, which can lead to safe work environments if used effectively on project sites. The purpose of this study is to provide a checklist to maximize the outcomes of the 5S approach concerning safety requirements. A grounded theory technique was used to analyze the interview data. Eighteen electrical construction experts with the snowball of construction workers, safety representatives, supervisors, site and project managers were interviewed. Ultimately, the present study simplifies 5S implementation for first-time users and outperforms the outputs of the existing users. It is expected that the presented 5S checklist will provide practical actions for safer construction sites.
