Wubshet Jekale, for his inexorable support, guidance, provides me insight & direction from the beginning of this research in all aspects. This thesis would not have been possible without his extended valuable assistance, energizing motivation, excellent advice and also spending his precious time. I would like to express my appreciation to all questionnaire respondents from contractors, Employer’s Representative and Employer staffs who sacrificed their time in filling the questionnaires and all organizations and individuals who provided the necessary materials and support for realization of this thesis. Especial thanks are forwarded particularly to Kassahun, Shalom Ashuro & Neway for their help while collecting data. I would like to place on record my gratitude to Henon Endale who gave me constant encouragement, without her care and love this thesis would not have been realized. I am indebted to my family, my classmates and friends who supported me. I am also very much thankful to my work cliques & my Company Afro-Tsion Construction P.L.C. for the positive attitude they have towards education and made me felt like the company asset. Finally, I humbly thank the almightily GOD, Good Angels and Saints for giving me good health, wellbeing and strength that enabled me to complete this thesis.
