Predictive Maintenance vs. Preventive Maintenance: Understanding the Difference
Proactive rather than reactive maintenance is quickly becoming the norm for enlightened facility...
Maintaining healthy indoor environments requires intelligent building maintenance strategies. This means looking beyond a single building system or method and understanding the four phases of planned maintenance. So, what are the four phases of planned maintenance? By exploring the answer, you can develop better, more efficient building maintenance practices.
Planned maintenance can be categorized in many ways but most commonly falls into four categories:
When used together, these offer a comprehensive and efficient approach to building maintenance. Savvy maintenance teams use the most advantageous elements of each, and understanding what these four phases of maintenance are will help stakeholders develop the best plan for each building.
Planned corrective maintenance happens in one of two ways. The first involves conducting maintenance on equipment and systems once they break down, also referred to as run-to-failure maintenance. The second occurs when scheduled maintenance or inspections identify specific issues that require correction.
Benefits of corrective maintenance include:
As part of a broader maintenance plan, corrective maintenance makes the most sense for non-critical building assets that can be inexpensively and easily fixed or replaced, or when systems have redundancies that minimize the risk of complete system failure. However, a corrective approach should never be the sole or even primary component of a maintenance plan.
Preventive maintenance can use three approaches:
Planned preventive maintenance also has numerous benefits.
However, preventive maintenance strategies have disadvantages. Often, stakeholders disagree on whether preventive maintenance is worth the cost and labor. It’s critical to weigh the potential costs of emergency repairs against the cost of preventive maintenance to ensure you are using resources effectively.
This phase involves identifying and analyzing the risk of an event occurring, whether for a minor repair or catastrophic failure, to determine maintenance priorities.
Risk-based maintenance entails:
By assessing risks, plans and processes can be developed to deal with various scenarios.
The rise of Internet of Things (IoT) technology has added a new dimension to maintenance planning. The data gathered by IoT devices allow facilities managers and maintenance personnel to identify problems sooner and resolve them more efficiently. When combined with smart building platforms that provide insights into building performance and conditions, data can guide multiple phases of planned maintenance, but none more so than predictive maintenance.
A smart building platform continuously monitors equipment performance and building conditions. Using machine learning algorithms, it learns how each connected component functions and can identify anomalies as soon as they occur, long before they are noticed by building occupants or even maintenance staff. As it gathers more information, it can also reliably predict future maintenance needs to ensure indoor environments remain healthy.
The benefits of predictive maintenance include:
A predictive maintenance approach complements the other three phases of maintenance and allows stakeholders to develop a more efficient overall strategy for maintaining healthy buildings.
While asking, “What are the 4 phases of planned maintenance?” is a good start, the most important question is “What are the best tools to create a robust maintenance strategy?”
Smart maintenance relies on smart technology. That means selecting a smart building platform with the capabilities you need to implement predictive maintenance, accurately assess risk, and make data-driven decisions. With a cutting-edge platform, like onPoint, you can harness the power of data to transform your maintenance program and support the health of your building.
