Project Delays on Cost Overrun Risks: A Study of Gasabo District Construction Projects Kigali, Rwanda
The purpose of this study was to examine the major causes of project delays and costs/risks that arise from project delays when implementing public construction projects in Gasabo district, Kigali City. The objectives were; to assess the relationship between project expected time and real time, determine project expected cost and real cost, to calculate both project delay and cost overruns and finally to identify the relationship between public construction project delay and their respective cost overruns. The study adopted a descriptive survey research design. Data were collected using open-ended questionnaire. Research samples were randomly selected from a total of 42 public construction project managers, consultants/ implementers for projects that had been ongoing for the period 2009 until 2012. A sample of 38 respondents was taken to assure a 95% significant result. To examine the nature of project delays and cost overruns, project delays and cost overruns were calculated, compared and regressed. The study revealed that 65.7% of public construction projects which were implemented between 2009-2012 were delayed, whereas only 5.2% of these projects faced cost overruns. From the results, the study recommends the use efficient mitigation techniques for planning efficiency rather formalities.
