Abstract
Long delays are causing sever influence in the country economy, impeding the country's road improvement efforts. The purpose of this research was to identify the major causes of schedule overrun from the Client, Contractors' & Consultants' side on the East Region projects of Ethiopian Road Construction. The research was descriptive and the research design was survey design. A quantitative research approach along with primary and secondary data sources was adopted for this paper. A structured close-ended was designed and purposively distributed out to the client (ERA), contractors and consultants working under ERA. Since the target population was small respondents were selected using the census method. Out of 63 questionnaires, 52 were able to be retrieved with a response rate of 82.5%. The data gathered using the questionnaire was analyzed with the help of Statistical Package for Social Sciences (SPSS version 20). This paper studied a list of road construction delay causes (25) factors gathered from literature having different types of construction, different countries, different periods and different numbers of delay causes. Relative Importance Index (RII) was calculated and from the overall relative importance index analysis, most critical factors of road construction delay have been identified as (1) Financial difficulties of the client; (2) Delay in progress payment by owner; (3) not implementing the design review during the planning stage; (4) Delay to deliver the site/Right of way; (5) Financial problems faced by the contractor among the top five factors contributing to road construction project time delay in the East Region. Therefore, conducting research in this field will be of utmost importance in order to lessen the incidence of late delivery (schedule overrun) of road projects and, if at all feasible, to prevent it. The main recommendation made by this study for reducing the likelihood of schedule overruns is the implementation of effective proactive project management by the important Contractual parties, more specifically by the Client and the Consultant, beginning with the planning and design phase and continuing through the project's final completion.
