The purposes of Construction performance evaluation, which involves setting new operating targets and standards has been raised among the majority of water supply construction projects. The thesis was focused on the factors identifying, performance evaluation, and improvement strategy, which makes a water supply construction project focus on identifying improvement areas. The goal of the study is to pinpoint the key elements influencing project performance and provide methods for enhancement. Both qualitative and quantitative methodologies were used in a mixed research strategy. 184 respondents, including clients, contractors, consultants, and community stakeholders engaged in 48 water supply construction projects carried out between 2019 and 2023, provided the data. Project characteristics, labor and material factors, contractual relationships, external environmental factors, client-related issues, contractor and consultant performance, safety and health conditions, leadership, and project procedures were among the categories of factors influencing project performance that were examined in this study. The data was analyzed using regression analysis and descriptive statistics with SPSS software. The findings showed that all of the projects under consideration had some level of cost escalation and delay, and the majority of water supply construction projects had considerable time and cost overruns. Contractor capability, consultant efficacy, project procedures, leadership, labor and material availability, client commitment, and external environmental circumstances are important variables that impact performance. The results demonstrate that while project procedures, quality flaws, and client satisfaction exhibit moderate significance, contractor and consultant-related factors, along with time and cost management, have very significant effects on project performance. The study concludes that modern construction management techniques like lean management, PDCA cycles, and Kaizen principles, as well as strengthening monitoring and evaluation systems and improving stakeholder coordination, can greatly improve project performance. In order to enhance the effectiveness, sustainability, and quality of water supply construction projects in the Oromia region, the study offers contractors, consultants, and project owners useful suggestions.
