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. The aim of this research is
to assess factors contributing for time overruns on road construction projects in Addis
Ababa city Administration in the views of road construction stakeholders.
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.
Key words: time overrun, causes, factors, asphalt road construction projects, Road
construction project stake holders.
