![]() However, it’s considered acceptable for non-critical items. It’s also referred to as breakdown maintenance or “run-to-failure.” Reactive maintenance is associated primarily with unplanned repairs and high costs for repair or replacement. Other maintenance strategies are generally categorized as reactive maintenance because a component is rectified when it’s defective. ![]() Similar to predictive maintenance, servicing is performed as needed based on the condition of the component. This takes predictive maintenance a step further by utilizing sensors on machinery to allow for real-time results to be fed into preventive maintenance software. During a scheduled shutdown (i.e., a break between college semesters), all known defective and deteriorated components are repaired or replaced. This may also happen at utility companies and continuous process-type facilities. This usually occurs in colleges and schools, and other establishments that have cyclic usage. Such replacements eliminate high costs and unplanned downtime, as happens during a breakdown. It requires replacing worn, broken, or inoperative building components before their failure. This strategy typically involves small tasks, such as changing filters. It includes inspections, cleaning, and machine servicing regularly (weekly, monthly, annually, etc.). Some of the other specific types of preventive maintenance strategies include: Additionally, preventive maintenance requires upfront costs and may be labor-intensive. Excessive maintenance can result in functional degradation to critical assets. The drawback to preventative maintenance is the risk of excessive maintenance. For example, consider the significance of maintaining a fire alarm system in case of emergency, or maintaining the HVAC system to avert spreading Legionnaires’ disease. In addition to cost savings, preventive maintenance is important for building safety, which include its assets, as well as the potential loss of life. Predictive maintenance is analogous to a doctor monitoring a patient’s condition by performing physical checkups and lab work and prescribing some action based on the patient’s current state of health. Those measures aim to prevent costly repairs in the long run and to make the car last longer. Preventive maintenance on a building is analogous to changing the oil and checking the brakes and tires’ air pressure on a car. Some people consider predictive maintenance to be a type of preventive maintenance because they both share the goal of warding off equipment breakdown. Predictive maintenance involves the combined use of various techniques to determine the equipment’s condition, including thermography, vibrational analysis, the application of lubricating oil, and acoustical analysis. It also includes regular inspections to meet the objective of forecasting equipment failure. ![]() Rather than maintenance performed at scheduled intervals, predictive maintenance entails work performed based on a system’s or component’s condition. Predictive maintenance (PdM) differs from preventive maintenance. The objective of preventive maintenance is to prolong service life expectancy and prevent equipment failure, thus minimizing unscheduled downtime and reducing overall maintenance costs by correcting defects at the onset, before they become significant problems. Note that the service completed in this regard isn’t based on the component’s condition. It includes regular inspections and selective service and repairs to the building’s equipment at set intervals based on usage or time. Preventive maintenance (PM) is a proactive strategy for building maintenance that keeps the building’s critical assets in good working order. But of particular importance for preserving buildings, equipment, and the grounds is preventive (or preventative) maintenance. Regardless of the size or type of a commercial property, various kinds of maintenance must be performed, including general upkeep, emergency repairs, and special inspections (such as may be directed by an insurance company).
