Abstract:
Currently, Ethiopian’s construction industry is in a struggle of undertaking mega projects that
demands huge physical resources, finance and political decisions. However, the lion share of
design preparation and supervision part were goes to the consultant firms. Therefore, the project
consultants play a very significant role in providing services in the production of well-coordinated
design, timely supervision and proper contract administration from the beginning to the
completion of the project. This helps to overcome the very common problems of projects such as
claims, project delay, poor quality product and greater uncertainties of project cost. Beside, when
the consultancy services are not effectively and properly delivered, it is very difficult to ensure the
successful completion of the primarily objectives of the given projects.
Therefore, this study aims to assess the major factors affecting the performance of project
consultants, their impacts on project success and remedial measures in case of Jimma Town. To
