The issue of construction project delays is commonplace in Ghana. Major infrastructure projects undertaken by Ghana ports and Harbours Authority experience the issue of delays. Port expansion and other infrastructure improvement projects undertaken by GPHA, have all exceeded their proposed completion dates. This research sought to evaluate the causes of construction project delays using Ghana Ports and Harbours Authority as a case study. The study aimed to find the important causes of delay in construction projects and to identify the critical negative effects of the delays on construction projects undertaken by GPHA. A questionnaire survey was conducted among purposively sampled respondents who have collaborated with GPHA on different construction projects. Quantitative method of research was adopted for data gathering. Using the Relative Importance Index (RII) technique. The findings revealed that the important causes of project delays were, Political interference; Insufficient data collection and surveys before designs leading to errors; Inadequate cash flow due to non-payment; Unexpected ground conditions. Again time overruns, cost overruns and disputes between contracting stakeholders were established to be the critical negative effects of delays on construction projects undertaken by GPHA
