Effective supervision of road maintenance projects in the Kingdom of Saudi Arabia based on performance indicators [Master’s thesis, Zarqa University, College of Engineering, Jordan]https://hdl.handle.net/20.500.14154/77919This study aimed to examine the effectiveness of road maintenance project supervision in Saudi Arabia based on performance indicators. A descriptive-analytical approach was adopted, using questionnaires and surveys alongside official project documents to ensure the reliability and accuracy of the collected data. The study sample included supervisors, technicians, and officials from government agencies and specialized companies. Using stratified random sampling, 250 questionnaires were distributed, and 211 valid responses were obtained, representing a response rate of 84.4%. All participants had at least two years of practical experience and participated voluntarily. Descriptive analyses indicated a high level of importance across all dimensions of effective supervision. Performance-based supervision using Key Performance Indicators (KPIs) scored an average of 3.98, while the average overall implementation results were 3.93, and the average road maintenance KPI was 3.91. These results reflect a strong consensus among participants regarding the crucial role of performance-based supervision in achieving effective project outcomes. The study recommends standardizing key performance indicators, implementing real-time monitoring systems, enhancing supervisory efficiencies, ensuring contractor accountability, promoting transparency, and encouraging innovation to improve the effectiveness of road maintenance project supervision.148enEffective supervisionroad maintenance projectskey performance indicators (KPIs)performance-based supervisionKingdom of Saudi ArabiaThesis
