Hadn't been his invaluable help even the possible would be impossible. Then I would like to express my sincere appreciation and gratitude to my advisor, Dr.Abraham Assefa for his invaluable guidance, kindness, support, and encouragement throughout the course of my research work. I would appreciate his cooperation in sharing his experience and kindness in treating his student and advisee. Furthermore, I give my special thanks to ERA for sponsoring and funding to conduct research work and to AAiT, Addis Ababa University, for their collaborative effort to provide master‟s program. I would also like to thank all people and organizations and firms who supported and provide me the required data to conduct this study. I give my special thanks to ERA Design management team leader to Engineer Delelegn and north region directorate team leader Engineer Gizachew for their valuable support in providing me data for the research work. Last not least I would thank my beloved wife Meron G/Medhin for her invaluable encouragement and cooperation through this thesis work, and for all of my life. Besides gaining knowledge thorough formal education , what I learned during the post graduate program study is that distance won't matter, what matters is commitment, because I was regularly traveling 47 km to attend morning class at 9.00A.M. I always trust in almighty GOD because everything is possible for him. MSc Thesis-Seyoum Admasu Seifu(AAiT-COTM) Page iv Impact of Design Cost On performance of DBB Road projects: In the case of (Ethiopian Federal Roads) Abstract Design cost is one of the main factors which affects design and project performance; in terms of cost, time and quality. The main objectives of the study was to identify and assess factors affecting design cost and to assess the impact of design cost on design and project performance taking DBB road projects in the case of Ethiopian federal roads. The study had important implication in addressing the impact of design cost on project performance. Seven factors affecting design cost of highway projects have been identified. Among these factors: consultant related factors, market condition related and consultant selection related factors ranked first to third position to highly impact design cost. The study has also identified ten factors affecting design performance of highway projects. Among these; Overall quality of design firm, complexity of the project condition ranked first to second position to impact design performance and both Overall size of design firm and complexity of the project function ranked third position. The impact of design cost on design and project performance was also assessed by this study, and it revealed that design cost highly impact both design as well as project performance. Taking 89 DBB road projects of federal Road Authority as case study, the findings of this thesis revealed that, design cost of DBB road projects of Ethiopian federal road projects is too less relative to its construction cost which is less than 1% of its construction cost. The study has also revealed that design cost per kilometer of DBB road projects has an inverse relationship comparative to its kilometer coverage, which is as project length coverage increases design cost per kilometer for that particular project would substantially decreases.
