In Saudi Arabia, different factors affect the quality of delivery of public construction projects. These factors are of major concern for the government and for the construction professionals. Therefore, the aim of this study is to investigate these parameters in Riyadh city, Saudi Arabia. Accordingly, opinions of 50 Saudi construction professionals are collected using questionnaire. The research sample includes participants of different ages, jobs, education and experience.
The results show that the companies of 60% of the sample adopt clear definition of quality. This finding was reported by 88% of the older participants. Similar opinions were reported by 70% of consultants, 65% of contractors and 52% of site engineers. Same finding was reported by 71% of high school, 67% of high education and 55% of university educated participants along with 80% of the experience participants.
