PERCEIVED CAUSES OF PROJECT IMPLEMENTATION DELAY ON THE CASE OF KALITY WASTE WATER LINE AND TREATMENT PLANT REHABILITATION PROJECT

Abstract

On-time completion and compliance with assigned project time of every project are the most important factors in the success of project plans. Project delays have been critical problems of many projects around the world in general and in Ethiopia in particular. Taking this into consideration, time overruns is one of the major problems in the construction projects. The main objectives of this research are to assess the dominant causes of project delays and, identifying possible and practical measures that can minimize project delays in Kality waste water line and treatment plant rehabilitation project. These objectives are achieved through the implementation of the research methodologies that are mainly literature review and questionnaire survey conducted to identify and evaluate the significant factors contributing to time overruns within the projects of interest. A review of literature have categorized the factors that cause delays in the four categories, those are due to; contractor’s responsibility, Client’s responsibility, Consultant’s responsibility and external factors. The total of 52 questionnaires were distributed and 46 questionnaires were collected from all parties; managers, team leaders, experts and others. From the data analysis and findings of the research; the top main significant causes of project delays are, waiting time for approval of design, Poor engineering estimate and frequent rework. The top ranked impacts of project delays identified by this research are Loss of end users benefit that will be obtained if it has been completed on time, Project time extension, Contribution to the development of the city would be affected has been ranked in the first, second and third position as impacts of project delays. Finally, the study recommended the ongoing project, Kality waste water line and treatment plant rehabilitation project to have committed leadership and management, timely decision process, advanced contract and project management, systematic control mechanism and effective and efficient strategic planning and management.
