Factors Affecting the Performance of Public Construction Projects: A Study in Selected building construction Projects in Jimma Town, Ethiopia

Abstract

Despite a significant allocation from the annual public budget to public construction projects, achieving alignment with the country's development goals remains a challenge in terms of schedule, cost, and quality. This research delved into the factors influencing the success of public construction projects in Jimma Town. The study, based on a sample of 61 respondents from randomly selected on-going projects, employed quantitative analysis through descriptive and inferential statistics using SPSS version 20. The analysis, which included frequency distributions, mean, and standard deviation, prioritized factors using the Relative Importance Index (RII). Pearson correlation assessed associations between independent and dependent variables, and ordinal regression analysis explored the contribution of selected variables to project performance. The outcomes, represented visually through tables and figures, revealed ten pivotal factors significantly shaping project outcomes. Foremost among these factors is the proficiency and experience of project managers, closely followed by resource availability tailored to project needs and contractors' financial capacities. The study underscores the interdependence of these aspects, wherein experienced team members, committed contractors, and effective on-site management also play substantial roles. Moreover, the research highlights the significance of effective contract administration and managerial skills. In contrast, external factors like economic conditions and political dynamics exhibit a lesser influence on project performance. These findings provide stakeholders with a strategic roadmap to enhance project outcomes. Key areas for improvement include fostering skilled leadership, optimizing resource management, and facilitating effective communication among project contributors. Stakeholders are recommended to prioritize on-going training for project managers, enhance oversight of contractor performance, and develop strategies for managing external factors. By addressing these key aspects, stakeholders can contribute to the successful execution of public construction projects in Jimma Town, aligning them more closely with the nation's development objectives.
