ASSESSMENT ON THE PRACTICE OF CONSTRUCTION WORK SCHEDULE PREPARATION AND CONTROL OF PUBLIC BUILDING PROJECTS IN ADDIS ABABA
Construction projects requires a coordinated effort by all teams involved for effective project time management. In Ethiopia, most construction projects fail to be completed within the specified contract time. As a result, the expected services are excessively delayed to provide the intended purposes. This practice needs to improve to manage projects in effective and efficient manner. Therefore, this research focuses on the assessment of construction project schedule preparation and controlling practices. Thirteen Public building projects in Addis Ababa were studied to find out the current practices by adopting the processes of project time management as a study model as well as assessing the factors affecting and improvement parameters based on researchers’ suggestion. The study was carried out through desk study, questionnaires and interviews. Mean Value Analysis and TOPSIS for Multi Criteria Decision Making analysis methods were adopted for data analysis. The results indicate that more than 70% of the projects are behind schedule, due to low practices in establishing procedures to schedule preparation and control, and limited Project Management software application for performance analysis. Factors that mainly affect schedule performance are unrealistic estimates for effort and duration, limited knowledge in performance evaluation and design changes. In addition, required improvement parameters suggested by the respondents are creating a well-planned scheduling process, establishing schedule management procedures, applying appropriate scheduling software, adopting schedule management methodologies and continuous monitoring procedures.
