    (Addis Ababa University, 2014-11) Ermias, Dereje; Jekale, Wubishet(phD)
    One of the most important responsibilities of construction project management is the planning and scheduling of construction projects. The problem of using improper construction works program in ERA road projects is one of the causes for delay of projects and these have a debilitating effect on parties to a contract in terms of a growth in adversarial relationships, distrust, litigation, arbitration, cash-flow problems, and a general feeling of apprehension towards each other. This study focused on the preparation and implementation of construction works program in ERA road projects. The objectives of the study were achieved through a desk study, interview and questionnaire survey to identify the ways of preparation and implementation of construction works program, challenges and to seek the improvement methods. A ranking system using the Relative Index (RI) method had been adopted to find the most significant factor for each section in questionnaire. Most important tasks identified for the preparation of construction works program were to define the scope of work to be performed using work breakdown structure, estimate durations for each defined task using tender quantities, expected crew-size and historical outputs for similar work, defining working calendars, develop activity dependency. During implementation the most important were work program should be updated to recognize delay, using construction time effectively and applying proper efficiency is critical and proper resource utilization is used to avoid cost overrun. According to the findings from the questionnaire responses, desk study and interview the major challenges in preparation and implementation of construction works program were cash flow problem of contractors, delay in site mobilization by contractor, the climatic condition at site, design change and right of way problem. The results of this study indicated that the most recommended improvement methods were contractor should manage his financial resources and plan cash flow, there should be a continuous, proper planning before construction, so that resources and time are sufficient and there should be a good attitude among professionals regarding construction works program. This study is therefore, to suggest improvement methods which can help to use construction works program properly in road projects. Key words: Preparation and implementation, challenges, improvement, ERA road projects.
