Developing Framework for Implementing Total Quality Management (TQM) in Sustainable Industrialized Building System (IBS) in Construction Projects

The construction sector is increasingly shifting towards sustainable and efficient methodologies, with the industrialized building system (IBS) playing a pivotal role in this transformation. Despite this, the adoption of total quality management (TQM) in IBS projects faces significant challenges, including a lack of comprehensive understanding of TQM standards and resistance to change within the industry. This study addresses these gaps by developing a comprehensive framework for implementing TQM in sustainable IBS construction projects. The objective is to enhance project quality and sustainability by addressing critical issues such as limited stakeholder awareness and opposition to TQM adoption. Using qualitative methodology rooted in phenomenology, this study explores the lived experiences of key stakeholders involved in IBS projects, including project managers, construction professionals, and government officials. Data were collected through in-depth interviews to capture their perspectives on TQM integration in the IBS context. The findings highlight the crucial role of TQM in fostering continuous improvement, enhancing stakeholder collaboration, and ensuring adherence to quality standards throughout the project lifecycle. The proposed framework incorporates essential TQM principles such as process optimization, employee engagement, and customer focus, providing a structured approach to overcoming the barriers to effective implementation. Furthermore, the framework promotes sustainability by reducing waste and improving energy efficiency in IBS projects. This study offers valuable insights for construction professionals, policymakers, and industry stakeholders, presenting practical solutions to improve the quality and sustainability of IBS construction. Leadership, cultural transformation, and continuous improvement are identified as key factors for successful TQM integration, ultimately leading to more efficient and sustainable building processes in the construction industry.
