The success of infrastructure and development projects largely depends on their authenticity, necessity, and proper implementation. However, weak project site supervision often results in the approval and completion of unnecessary or poorly executed projects, leading to wasted resources, inefficiency, and reduced public trust in governance. This study investigated how project site supervision can be strengthened to ensure that only genuine and necessary projects are funded and completed. The research employed a mixed-method approach, combining document analysis, surveys, and key informant interviews with project engineers, and inspectors. The study evaluated current supervision practices, identifies gaps and challenges in oversight, and examines the relationship between supervision mechanisms and project outcomes. Furthermore, it develops a framework for enhancing site supervision, focusing on transparency, accountability, and compliance with technical and financial standards. Findings highlighted that inadequate monitoring, lack of qualified supervisors, and weak enforcement of standards and specifications are among the key factors that allow non-essential and low-quality projects to proceed. Strengthening supervision practices through stricter monitoring protocols, capacity building, and the use of technology-based monitoring tools can significantly improve project integrity and sustainability. This research hoped to contribute to the field of project management and governance by emphasizing the critical role of site supervision in ensuring that resources are allocated efficiently and that infrastructure projects respond to genuine community needs.
