Maintenance refers to the process of preserving, repairing, and ensuring that the building or infrastructure remains in a functional state throughout its operational life. It involves all activities that help preserve the original condition of a structure or system and restore its functionality when parts of it become defective or worn out. The maintenance process is not just about fixing problems as they arise but also includes preventive measures that extend the life of the building and prevent the occurrence of faults in the first place. It is an essential aspect of building management, focusing on ensuring safety, comfort, and functionality for occupants while minimizing operational costs and disruptions. There are different types of maintenance activities, primarily categorized as preventive, corrective, and predictive maintenance. Preventive maintenance is scheduled and performed before a failure occurs. It includes regular inspections, cleaning, lubrication, and replacement of components before they wear out or break down. Corrective maintenance, on the other hand, occurs after a failure has been detected, where repairs are done to restore the system to its intended function. Predictive maintenance involves using advanced techniques, such as monitoring equipment conditions through sensors and analyzing data, to predict when maintenance should be carried out before failures occur. This approach aims to reduce downtime and optimize resource use. The functions of maintenance can be broadly categorized into several key areas. First, it ensures the operational efficiency of the building. Well-maintained facilities function smoothly, with all systems (such as electrical, plumbing, HVAC, and elevators) operating optimally. Maintenance also plays a critical role in safety. By regularly inspecting and repairing systems, it helps prevent accidents such as electrical fires, water leaks, or structural failures. In this context, maintenance is an essential aspect of risk management, ensuring that hazards are identified
