As Qatar continues its race against time in delivering construction and infrastructure projects by the fixed deadline of 2022, and later to achieve Qatar National Vision in 2030, project delay is an everyday reality since most of the public construction projects are experiencing widespread delays. These project delays posed strong evidence of the inconsistent performance of Qatari construction projects that warrants a systematic analysis of the delays. This paper aims to assess the delay factors and their impact on construction projects to generate strategic project delay mitigation approaches towards customer satisfaction. Data were gathered through a survey questionnaire. The analysis of data was aided by the use of Statistic Package for Social Science (SPSS) where the scores assigned to each factor by the respondents were tallied and then analyzed with descriptive and multiple regression statistical techniques. The contribution of each of the factors to overall delays was examined, and the ranking of the attributes in terms of their criticality as perceived by the respondents was done by the use of Relative Importance Index (RII). The results revealed that the major causes of delays in Qatar construction projects are external-related factors and contractor related factors. Recommendations for mitigating strategies for risk management system are tailored based on the findings of this research.
