Learn about the definition, advantages, and types of condition-based maintenance and additional tools for implementing a proactive maintenance method for your facility
Published 28 Apr 2022
Condition-based maintenance, also known as CMB, is a proactive maintenance technique that is performed depending on the condition of the asset. CBM doesn’t rely on a schedule-based maintenance, but on indicators that can determine if the asset is about to break down or has broken down.
The equipment maintenance supervisor or facility manager will determine a set of condition-based maintenance (CBM) indicators. In the event that these CMB indicators were met, the maintenance personnel will have to proceed with the maintenance of the equipment or machinery. The facility should have standard operating procedures (SOPs) to provide step-by-step instructions and guidelines on how the issue can be fixed for the maintenance personnel.
Condition-based maintenance is under the preventive maintenance category. What sets it apart from other types of maintenance is that CBM relies on real-time data of an asset’s condition and maintenance parameter levels. CBM is recommended for equipment and machinery that is highly critical for production and costly to repair and replace.
Every maintenance strategy has its strengths and weaknesses. Here are some of the advantages and disadvantages of applying condition-based maintenance:
CBM is performed on a need basis. This means that there can be less time spent on repairs and maintenance and that the personnel can make use of the time saved to do other tasks. This is in comparison to other types of maintenance such as regularly scheduled maintenance.
Another key aspect of condition-based maintenance is that the equipment and machinery can possibly have reduced downtime if the maintenance indicators set in place were appropriate for the facility. These performance measures could alert the maintenance personnel and they’ll know what SOP to follow depending on the affected maintenance indicator.
Lastly, having a reduced asset downtime means that production will run more smoothly and continuously.
Another scenario is that condition-based maintenance on minimal issues can be conducted even without shutting down the equipment, this reduces time on setting the equipment or machine back up again.
Since CMB is a proactive maintenance procedure, issues that could lead to equipment and machinery failure can be caught before they can happen. Once the maintenance measures reach a certain level, maintenance personnel will have to quickly respond by conducting a condition-based maintenance procedure to solve the problem.
Here’s a possibility that something can happen to a machine or equipment that wasn’t part of the maintenance indicators. This could leave the maintenance personnel to not know what to do and how to solve an issue. Furthermore, unpredictable maintenance measures can cause the maintenance team to be on standby, and some personnel will be responsible for observing the assets throughout their shifts. Additionally, there could be instances wherein multiple assets need to be repaired or maintained at the same time.
Maintenance supervisors will have to keep track of the unpredicted maintenance conducted and update the maintenance indicators accordingly to reduce stress on the staff and optimize their time on the job.
In connection with the previous disadvantage, condition-based maintenance will require a level of expertise for their maintenance staff depending on the equipment and machinery of the facility. This facility can also employ additional maintenance tools such as sensors and softwares which would need someone with the technical knowledge to operate the maintenance equipment.
There are 5 common condition-based maintenance strategies available which are:

The strategies mentioned earlier can be too costly and advanced for certain companies, especially for smaller businesses, but there are other ways for you to be able to implement condition-based maintenance such as using checklists tools to aid you during a visual inspection. Checklists tools can also be used for auditing the other CBM techniques—vibration analysis, infrared thermography, oil, ultrasonic, and pressure analysis.
Here’s an example of a facility condition assessment template:
