The construction industry is a driver of growth in another sector due to its heavy reliance on an extended and varied supply chain. Cambodia as a developing country, the construction industry significantly contributed to the economic development and has created a lot of jobs. The construction becomes one of the important pillars supporting the Cambodian economy. However, construction is also facing many complex issues to challenge foreign companies mostly on quality in construction projects. The quality of construction projects is affected in different ways by various factors. So determining the important factors influencing the quality of construction projects in Cambodia is significant to local Cambodian companies in better quality improvement and also to compete with foreign companies when contracting. The research used a quantitative methodology with 31 sample sizes for the pilot study, 385 sample sizes for the real study with 10 samples for In- depth interviews to confirm the study results. SPSS and AMOS programs were used in this study and the results indicate four important factors for evaluating the quality of construction projects in Cambodia such as avoiding disputes and claims, motivating and empowering employee training, enhancing customer/owner satisfaction, and completing projects on time.
