| Abstract: | Efforts to reduce the delay by mitigation or eliminate the delay by acceleration are measures that depend on the projects being considered for those measures. Based on the general objective of the research to find out the causes of delay in the Addis Ababa Transmission and Distribution System Rehabilitation and Upgrading Project, this study addressed three specific objectives, the magnitude of the causes of delay and project delay, by using descriptive analysis, and also carried out investigation the influence of causes of delay in project life cycle phases by utilizing multivariate regression model. Project life index and multivariate regression diagnostic tests were also carried out. The target population for this study was 452 individuals stratified based on the surveyed project actors where a sample of 212 respondents was established and only 171 responded. Questionnaires were self-administered and were dropped and picked immediately respondents were done filling them. Data collected was then presented using tables and figures. Statistical Package for Social Sciences (SPSS) software was used to analyze data. The findings revealed that the most project delay is towards execution project life cycle followed by planning phase. In addition, it is found out that the occurrence of project delay was rated as high. Lack of communication due to internal project influences has been the top propjet delay source. Further, this study revealed that the most project delay is towards inadequate resources, poor project planning, lack of communication, lack of monitoring and evaluation and client dissatisfaction across each the project life cycle respectively. The study concluded that pitfalls in project life cycle have been a source of transmission project delay. Finally, towards maintaining and improving late execution of the project as compared to the planned completion period and these delays are often as a result of miscommunication, the study recommends: leading, integrating people, and taking decisions to make a project a success and building trust and relationships among team members, as well as propagate desirable personal behaviors and clear communication rules by implementing the identified respective approaches for action. |
