The construction sector plays a vital role in national development, yet many projects continue to suffer from schedule delays, particularly in urban areas like Tuguegarao City. The purpose of this study is to provide the construction industry a better understanding of the key factors contributing to time overruns and to assess their effects on project duration. The study utilized survey responses from 20 construction professionals and analyzed the data using Relative Importance Index (RII), Multiple Linear Regression (MLR), and Monte Carlo Simulation (MCS). Results showed that natural disasters, materials delivery delays, shortage of materials, and lack of workforce were the top four significant causes of time overruns. The developed MLR model revealed that natural disasters and lack of workforce increase project duration, while material-related factors showed negative coefficients. The model yielded an R³ value of 0.608, explaining 60.8% of the variation in project duration. The Monte Carlo Simulation, using 1,000 iterations, estimated project delays ranging from 6 to 27 days, with an average delay of 16 days. In general, the results showed that the integration of statistical and probabilistic tools provides a reliable framework for analyzing and predicting construction time overruns
