Item Challenges of Scheduling of Federal Road Construction Projects in Ethiopia(Addis Ababa University, 2022-06) Getu Feyera; Abraraw Chane (PhD)Many road construction projects in Ethiopia are facing challenges of scheduling. Schedules are not usually prepared properly; the schedules are not realistic in most cases; and there are no timely revisions of work schedules. Though there is huge budget being allocated to the road construction industry in Ethiopia, there are prominent delays of completion of projects due to improper scheduling and lack of controlling work schedules. Therefore, this research was conducted to identify the major challenges of scheduling of Federal road construction projects in Ethiopia. Questionnaire survey was used to collect data of challenges of Federal road construction projects. A total of 58 questionnaires from the staffs of Employers, Consultants and Contractors of twenty projects were collected. The data collected was analyzed using descriptive statistics. The results of the study showed that Controlling Schedule, Planning Schedule Management and Estimation of Activity Durations are the major difficulties observed from “Project Time Management Processes”. Respondents rated 12 major challenges of scheduling of road construction projects. The most important challenges observed according to the study were: not considering risks in schedule, improper allocation resources, using similar variables of other projects and absence of training on scheduling. The major negative effects of having unrealistic work schedule were delayed completion time, increased project cost, low profitability of contractor and low satisfaction of Employer. Resource leveling and schedule crashing were not being implemented by 53% of road construction projects. Spearman rank order correlation analysis was used to evaluate whether consensus of opinions exists between groups of respondents. From the analysis of the results it was found that consensus of opinion exists between the groups. It is anticipated that these findings will guide efforts to improve the planning, preparation and controlling of schedules of road construction industry.
