| dc.description.abstract | This study tried to assess the effect of some dominat time and cost overrun factors in Addis Ababa University building constrcuction Projects.The researcher used descriptive research method. A questionnaire with items of 24 was distributed and then collected with a response rate of 100% and the respondents were interviewed to to get further informationon on the specified factors.Moreover, The actual project document showed that there were average 46% of time overrun and 25% of cost overrun within the projects. The findings indicate that the major causes for project time overrun were improper planning and poor scope definition that had significant consequence of design change to implement the project. The other critical factor for the cause was poor communication in which the project stakeholders couldn’t work harmonically to effectively achieve the projects goals. Factors such as wner’s interference and slow decision were also played very significant role in wasting the project time. The contractors’ and consultants’ experiences as well as equipment availability and failure played moderately significant whereas factors like contract management and quality assurance or control had very significant contribution to the overall project time overrun. Similarly, the researcher reviewed the above mentioned six project documents to assess their cost and find if there were variations between the planned and actual costs. The average cost overrun of the total projects was found to be 25%. The planned cost of each project was in millions of birrs and an average of 25% increase from each project indicated so big monetary escalations. As the respondents’ responses, the major causes for the project cost were the factors described in the above table. Change in foreign rate, contractual claims, additional work at owner’s request, design change, quality of materials, cost under estimation and insufficient funds were very significant factors that increase the project cost. Factors like poor schedule management and cost infliation were extremely significant to cause the overrun. Whereas factors like delays between design and procurement phases, tendering maneuvers and decision delay by supervisors were moderately significant in causing project cost so that the sum of the factors contribute to the overall project cost overrun in the project. Future research may investigate in detail including out. | en_US |
