Quality in construction projects is important in terms of providing safe, durable end products at an economical cost, but evaluation of the efficiency of Quality Management Systems (QMS) is a long-standing incongruent issue due to haphazard measures and various implementation processes. The present paper will explore QMS effectiveness in the construction sector by conducting a literature and industry review to determine the outcomes of performance and identifying factors that lead or contribute to success or failure. The goals of the study include assessing the average QMS elements, such as ISO 9001 guidelines and TQM operations, gauging performance through metrics, including defect elimination, cost reduction, and conformity rates, and proposing the strategies to improve the performance of the system. The paper takes a statistical approach to designing the research findings using data aggregated in peer-reviewed journals and reports in the industry. Findings indicate QMS results in 15-25 percent defect eliminated and 10-15 percent cost savings and leadership and training are the main facilitators albeit obstacles remain such as resource insufficiency. The work will also provide construction professionals with a useful reference point in terms of assessing the effectiveness of QMS, facilitate the compatibility when applied together with information technology such as BIM, and facilitate a more sustainable activity by avoiding unnecessary pieces of work on rework.
