The research on Design Management of Construction Projects focuses on investigating the application of lean design management principles, agile methodologies, and Building Information Modelling (BIM) within the design process. By integrating these approaches, the aim is to enhance project workflow efficiency while minimizing wastes, errors, and reworks. Additionally, the research seeks to maximize value generation for stakeholders by streamlining the design phase. Through the synergistic application of lean principles, agile strategies, and BIM technologies, this study endeavours to transform traditional design management practices in the construction industry, ultimately leading to more efficient and effective project outcomes.
