Irrigation projects are vital for enhancing agricultural productivity and ensuring food security. However, delays in their implementation can significantly impact farmers’ livelihoods and economic stability. This study examines the causes of schedule delays in irrigation projects in Oriental Mindoro, Philippines, identifying key contributing factors such as adverse weather conditions, irrigation water delivery schedules, contractor performance, and right-of-way (ROW) issues. Using a descriptive-comparative design, data were gathered from 32 respondents through surveys. Statistical analysis, including independent t-test, was employed to determine variations in perceptions based on respondents’ experience levels. Findings indicate that weather-related disruptions and scheduling conflicts are the most significant contributors to project delays, often resulting in work suspensions and variation orders. Poor contractor performance and ROW disputes were also found to be moderate factors. Based on the findings, this study proposes strategies to mitigate delays, including enhanced project planning, adaptive scheduling, and stakeholder engagement. The research underscores the need for improved project management approaches to ensure timely completion of irrigation infrastructure, ultimately benefiting farmers and enhancing agricultural resilience. Future studies should explore the integration of technology-driven solutions for better project oversight and efficiency.
