This thesis is a study of Quality Management, its use, effectiveness and acceptance by the construction industry. The objective of this research is to determine to what extent the Quality Management System (QMS) helps personnel at different levels of organizations perform their tasks. It also examines how the QMS assists them to meet the quality management expectations of their organization and to develop a methodology and appropriate mechanisms (procedures) for evaluating and measuring the effects of quality management. This research was carried out by performing an in-depth examination of the effect and impact of an implemented QMS on Hong Kong construction companies and their personnel at different levels of the organizations. This study has contributed to the knowledge currently available regarding the application of QMS. Its findings will be of general use in the construction sector and also for the industry practitioners as they will be able to apply the methods and processes developed.
