Abstract
Effective evaluation of performance with respect to time and cost of road construction projects should be present and given proper attention in order to attain the projects’ goals. Otherwise, risk
can manifest itself in a variety of ways, including time and expense overruns, financial losses, loss of life, environmental damage, material spending, and a variety of other failures. This research aims to identify the key causes of the Addis Ababa road project's performance with respect to time and cost, and to provide a roadmap for future work in addressing this issue.
