| dc.description.abstract | Due to the significant importance of road construction for socio-economic development contractors have accomplished projects on time, within budgeted cost, and required quality. In Ethiopia, including Amhara region North Wollo zone various road project suffered in various challenges which is a delay in completion time, cost overruns and poor-quality performances. So, this study mainly focuses on the assessment of road construction project performance in the North Wollo Zone. To solve such problems the research data was gathered in three ways questionaries case studies and interviews in North Wollo Zone actively ongoing road projects were 14 so the population of the studies and from this population 42 questionaries samples were prepared and distributed to the respondents. Thereafter, the questionnaire sample was prepared and collected then the results were analyzed, by RII. And their reliability was calculated through Spearman correlation coefficient ρ & Cronbach alpha (α) so based on the analysis the main factors affecting the performance of road project was mainly in these categories such as cost, time and quality and health and safety factors. So escalation of the material price (RII=0.89),right-off way problems(RII=0.87), underestimates of the contract price (RII=0.84), delay due to material storage (RII=0.82), poor project management (RII=0.81), time extension claims (RII= 0.73), planned time for construction (RII=0.73),lack of experienced workmanship (RII=0.82),quality of equipment’s and raw materials in the project (RII=0.81), Climatic factors, (RII=0.74) Project complexity due overlap (RII=0.68) and soil condition of the site (RII=0.65) are factors that affect the performance of road construction projects. Effects of poor project performance was a delay in completion time (RII=0.87), cost overrun (RII=0.84), decrease in productivity (RII=0.81), suspension of work progress (RII=0.79), those effects can be solved by developing systematic work plans and schedules with (RII =0.89) Learning from best practice and experience of others with (RII=0.89), Adequate funding (RII=0.85), Adherence to developed work plans and schedules (RII=0.84) are mitigation measures that improve poor performance | en_US |
