| description | This study investigates delays in execution of public sector construction projects in Ghana. A review of literature revealed that previous studies on construction projects focused on cost, time overruns, as well as the causes of delays. It is against this background that this study assesses the causes and effects of construction project delays and means of averting such delays. The research design used in obtaining empirical data from a sample of 290 respondents was a survey research design. Questionnaires were used as instruments for data collection, and a Statistical Package for Social Sciences (SPSS) used for the data analysis. The statistical tools employed in the study include frequencies, percentages, Relative Importance Index (RII), Spearman correlation analysis and Chi-Square Test. The findings of the study revealed that some critical contributors to road construction project delay in Ghana during the project execution phase are clients' low cash flow to complete the project, contractors' financial constraints on the project, and improper planning of the project life cycle especially during the bidding phase. Site restriction, weather effects and changes in governmental regulations were found to be the least contributors to projects delays. These delays have a negative impact on project performance, project duration and force project participants to modify and adjust their finances. Investigating the way forward, the study explored strategies that are for averting the delays in executing construction projects. The study found that respondents were undecided in their rating on adequacy of training for project staff on specific requirements of construction projects. Other factors such as adequate of knowledge of contractors on project task, effective mobilization and release of resources, early engagement of project managers as well as adequate and effective supervision of construction activities were each identified as strategies that are applicable and feasible in averting the delays in executing road construction project activities. |
