Abstract: Time overruns are the most common issue in construction projects, which have a significant negative impact on the project and the parties involved. This also applies to National Competitive Bidding (NCB) construction projects in municipalities, jeopardizing project timelines, costs, and quality standards. Poor performance by professionals in rural municipalities has resulted in inadequate infrastructure development in these areas. The goal of this study is to understand the causes and effects of time overruns by employing an exploratory and descriptive research methodology. The data from clients, consultants, and contractors consistently highlights key factors contributing to project delays, including adverse weather conditions, limited involvement from contractor head offices, insufficient consultant experience, inadequate site management, and delays in site mobilization. These delays incur substantial costs related to materials, land acquisition, labor, and market risks. The results included that 52.17% the projects experienced time overruns ranging from 24.4% to 514.71%. Furthermore, 21.73% of projects experienced cost overruns, with the highest at 19.92%. These findings provide critical insights for improving project management and addressing construction time overruns. It recommends conducting national-scale analyses to gain a comprehensive understanding of construction delays and to implement effective mitigation strategies.
