Development of a Dynamic Model of Quality Performance in Thai Construction Industry

Many quality performance tools are implemented in the construction industry to enhance the quality performance standard. This paper utilizes an ISO 9001 standard implementation to develop a dynamic model of construction quality performance in the Thai construction industry. The model consists of five sub-models, namely the Leadership, Plan, Do, Check, and Act sub-models. Five levels of performance maturity are also developed in this study to plan for long-term improvement. The simulation results reveal that a company takes seven years to proceed from level 1 to level 2 of maturity as it lacks experience and knowledge. With more experience, the company progresses through to higher maturity levels in a shorter period of time. The model achieves the perfect implementation score of 1,000 points at the end of year 23. This study results can be used to aid the construction industry in the effective planning for long-term quality improvement.
