Siraw Yenesew Tesfa
Abstract: It is well known that most road construction projects in Ethiopia and Addis Ababa city are exposed to time and cost overrun or both. It becomes difficult to complete road projects in the allocated cost and time. Therefore, this research was carried out to dig-out information on the factors that cause time overrun on Asphalt road construction projects in Addis Ababa City administration. Questionnaire survey was used to collect data on causes of time overrun. A total of 47 questionnaires from owner (AACRA), contractors and consultants were collected on the common factors to contribute for time overrun on asphalt road construction projects completed from 2000-2005E. c in Addis Ababa city administration by using a purposive sampling technique and analyzed using both descriptive and inferential statistics. Secondary data (asphalt road construction projects completion report) was used to know the real extent of time overrun on the projects understudied. From the result, it was found that 80 % of the projects suffered time overrun. The most important causes of time overrun were found to be slow cite clearance, contractors financial problems, Inflation, progress payments delay by owner, inaccurate cost estimation, and delay in commencement. Spearman rank order correlation analysis was used to evaluate whether consensus of views exists between groups of respondents (owner versus contractor, owner versus consultant and contractor versus consultant). From the analysis of the results, it was found that there is no consensus of opinion between owner versus contractor and owner versus consultant respondents on the factors that cause time overrun but there is consensus between contract and consultant respondents. Lack of adequate literatures on my case study was the limitation of this study.
