Project scheduling plays a vital role in successful completion of a construction project, despite the crucial role of this tool, there still exist many challenges in using it efficiently. Some projects schedules are established at the conception of the project and never evaluated for feasibility until problems arise. Besides, some constructors lack the expertise required for preparing effective project schedule. This study therefore, examines the factors affecting project scheduling and also establishes the severity of these factors. Review of extant literatures revealed the factors affecting project scheduling and these were structured into a questionnaire to get empirical data from the professionals. Statistical tools were used to analyze the empirical data collected. It was revealed that the type, complexity and the materials requirement for the work are the most important factors that determines project scheduling; Poor managerial decision on critical activity, lack of expertise in scheduling and inaccurate estimate of human resources required are the top factors hindering the performance of project scheduling. This study recommends the use of qualified and certified professional in managing project schedule and the use of scientific approach rather than rule of thumb in estimating for labor and materials requirement, as this will enhance the performance of project scheduling in Nigeria construction industry and contribute to the optimal utilization of resources in project delivery.
