Rework in Building Information Modelling (BIM)-based construction projects have considerable implications for project timelines, costs, and efficiency. Despite the acknowledged potential of BIM, rework remains a significant and persistent issue, necessitating urgent attention. This study aims to model the relationship between BIM's key effect on rework and its critical strategies to mitigate and prevent such setbacks. The objectives include: (1) identifying key effects of BIM on rework within construction projects; (2) determining critical strategies for rework reduction in BIM-based projects; and (3) model relationship between key effect of BIM on rework in construction projects and its critical strategies. To achieve these objectives, the research methodology combines a comprehensive literature review with surveys conducted among BIM experts. The data analysis techniques encompass mean score ranking, normalization tests, and correlation analysis. Nine critical variables for rework in BIM-based construction projects are identified, with the top three being construction errors due to design misunderstandings, poor quality management by contractors, and poor coordination among design teams. Respondents highlight four critical strategies to reduce rework, including establishing a good communication network between parties, proper production planning, and implementing a quality management system. The insights gained from this study are intended to offer actionable strategies and best practices for reducing rework, ultimately enhancing project performance and profitability. Furthermore, the findings will explore the implications and limitations of the research, providing recommendations for future industry practices and policymakers aiding them in developing regulations that encourage the adoption of BIM practices to minimize rework in construction projects. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
