Important causes of delay in public utility projects in Saudi Arabia

This study was conducted to determine the most important causes of delay in public utility projects, based on the frequency and severity of the causes. A survey of randomly selected samples of contractors, consultants, and owners was carried out to assess the frequency of occurrence and the severity of impact of sixty potential delay causes. A frequency index and a severity index were determined for each cause. An importance index for each cause was then computed as the product of the frequency and severity indices. The results showed that the three panics surveyed generally agree on the importance ranking of delay causes. The causes were grouped also into six major categories of delay. The analysis showed lack of agreement among the parties on the ranking of the major categories of delay.
