This research aims to create preventive maintenance guidelines for electrical components in buildings, especially government buildings, by breaking down electrical components using work breakdown structures so that the identification of electrical components is complete and well-structured. The methodology used in this research uses archive analysis with validation by experts through a questionnaire based on the legislations and applicable research and previous research. The results of this research are guidelines for preventive maintenance for electrical components in government buildings that contain preventive maintenance steps for each component at an alternative design level with a time interval for each component. Preventive maintenance guidelines for electrical components in this building are formed using work breakdown structure described from level 1 to level 4 with their derivatives, namely alternative designs. From the results of the validation, there are 22 (twenty-two) work packages and 45 (forty-five) alternative designs for electrical components in buildings that need preventive maintenance with each activity, procedure and preventive action and time intervals.
