This study examines and analyses the salient factors that constrain work schedule performance and their contributions to the level of project time overrun in construction industries in Nigeria. The realization of project work schedule objectives is usually not achieved with certainly due to myriads of constraining factors encountered during the implementation stage of project life cycle. The survey method of research design was adopted. The primary data used in the study was captured with the instrument of research questionnaire and measured with Likert five-point scale. The methods of data analyses were the multiple regression and correlation analyses. From the analysis, both F-ratio and student t-test were used in testing the research hypotheses. The results of the analyses indicate that all the constraining factors contributed to poor performance of work schedules during project implementation. The most significant factor is the time constraint that arises due to wrong estimation, unforeseen public holidays, unpredicted whether and climatic changes etc. Other significant constraining factors are materials and machinery arising due to occasional, unavailability, cost escalations and scarcity. The study therefore recommends adoption of in-depth forecasting and scenario analysis of resources, effective project monitoring and control and proactive material management practice.
