<![CDATA[This study examines the implementation of a Work Breakdown Structure (WBS) in the preventive maintenance of the Total Fire System (TFS) to enhance building safety and reliability. Poor maintenance practices can compromise these aspects, increasing fire risks due to inadequately maintained fire protection systems. Utilizing WBS, the study breaks down maintenance tasks into manageable components, improving clarity and effectiveness in planning, execution, and documentation. The hierarchical WBS framework, validated through expert feedback via the Delphi method, was applied in a case study at the Faculty of Computer Science building at the University of Indonesia. The case study demonstrated significant improvements in operational efficiency and compliance with fire safety regulations. WBS enhances task clarity, allows effective scheduling of maintenance activities, and establishes a reliable documentation system. Key benefits of WBS include optimized resource use, cost savings, improved team collaboration, and extended lifespan of fire safety systems. To implement WBS effectively, the study recommends comprehensive training for maintenance teams, fostering collaboration among stakeholders, and adopting continuous improvement practices. In conclusion, this study illustrates that WBS significantly enhances TFS maintenance effectiveness and can be applied across various building types, promoting structured and efficient maintenance practices to improve safety and reliability. ]]>
