Traditional methods suffer from poor coordination, resource misallocation, and scheduling delays, compromising structural integrity and increasing costs. This research proposes and validates an integrated operational model that leverages Building Information Modeling (BIM) and Work Breakdown Structures (WBS) to overcome these limitations. A mixed-methods approach was employed. A novel BIM-WBS framework was developed, incorporating best practices and relevant Indonesian regulations. Expert validation, using a modified Delphi technique with five domain experts and qualitative case study analysis, assessed the framework's feasibility and efficacy. Quantitative analysis, utilizing Kendall's W and descriptive statistics, evaluated expert consensus on key aspects. Findings demonstrate that the integrated BIM-WBS framework significantly enhances dam maintenance efficiency. It improves task organization, resource allocation, stakeholder collaboration, and risk management. Expert consensus highlighted significant benefits, including improved communication, reduced operational redundancies (estimated at 15%), and proactive issue detection. However, challenges remain, including high initial investment costs for BIM implementation, the need for comprehensive training to address technical skills gaps, and overcoming resistance to change. This research concludes that the BIM-WBS framework offers a robust solution for optimizing dam maintenance. It addresses critical gaps in current practices by providing a data-driven, collaborative platform for proactive decision-making. Policy recommendations include government support for infrastructure upgrades, the establishment of industry standards, and targeted training programs to facilitate broader adoption. Future research will explore integrating advanced technologies (e.g., AI, IoT) and conducting long-term impact assessments across diverse dam types and geographical contexts.
