Sierra Group FSD | Case Studies: Why is Preventative Maintenance More Effective than Reactive Maintenance?

Facilities management aims to provide efficient and effective facility maintenance services to a company that needs assistance. The service encompasses multiple disciplines to ensure the built environment’s functionality, comfort, safety, and efficiency. 

Most facility management teams will categorize individual tasks as either “reactive” or “preventative.” They may also lean towards a more reactive or more preventative approach toward facility maintenance in general.

In a reactive approach to facility management, a technician identifies and rectifies a problem once the asset has malfunctioned.  

Conversely, a preventative approach involves asset evaluation and management to help avoid failure and degradation.



It is important to know the difference because relying too heavily or solely on reactive maintenance can lead to significant financial losses, or worse, liabilities that can have a catastrophic impact on your brand reputation. Generally, taking a reactive approach to facility management can be 5X more costly than a preventative approach. 

To give you a direct window into real-world ramifications of negligent maintenance, we’ve compiled case studies that will reinforce the importance of preventive maintenance.

Plumbing Failure Shuts Down Server-stacked Data Center

On a popular facility and HVAC maintenance online message board, a data center manager recently shared a story that involved the total destruction of his center’s servers. It all went up in flames due to a short caused by an electrical malfunction. The key point of concern wasn’t that the owners could have avoided this catastrophe with minimal investment; it was the fact that some of the data center managers were fully aware of faults within their plumbing systems and simply neglected the issue until it was too late. 

The investigation following the incident revealed the data center was situated in an older structure with a documented history of minor water leaks. Some in the company’s management had already reported these findings and that the leaks were likely precursors of a major leak in the future. All of the risks involving potentially catastrophic financial and data loss were fully communicated to key leadership in their situation report. All parties understood with clarity that the risk would be significant. Despite understanding the gravity of the situation, they opted to install a monitoring system that could alert data center managers once a leak is detected instead of finding a comprehensive maintenance solution for their faulty plumbing system. 

Making matters worse, even the monitoring system was never implemented due to indecision from the data center’s key leadership, resulting in Murphy’s Law taking full effect. Not long after, with no preventive solutions in place, a severe leak began one weekend that took down millions of dollars worth of servers and customer data, resulting in massive financial losses and damage to the company’s reputation. 

Such a disaster should have never transpired, considering what we know today. A simple pipe inspection with camera monitoring or a hydrostatic test would have shown the areas with active leaks or with a high propensity for leaks. As a facilities manager, if you’re concerned about service and operational disruption, plumbing systems maintenance can be conducted without doing so. Sure there will be costs incurred with preventive maintenance, but they are incomparable to the astronomical costs and irreparable damage to your company’s reputation should a similar event such as this occur at your facility.  

High Voltage Cable Shorts Hospital’s Power

If you’re a patient at a hospital, a power outage with an inoperable backup power system could very well be your worst nightmare because this poses obvious existential ramifications. Simply put, it becomes a life or death situation. 

According to an anonymous message board member, such an incident occurred when a ground fault in a high-voltage cable between switchgear units shorted more than two-thirds of an electricity grid at a hospital in Sweden. Although the outage only lasted 1.5 hours and no harm was done to patients, it took a considerable length of time for key hospital functions to recover. Patients were unable to call for assistance, medical storage secured with digital combinations was made inaccessible, surgeons could not perform, and food distribution was delayed. The hospital’s IT systems too were inoperable long after the outage was fixed. 

So how did this happen? The facility manager of the hospital’s control center was not trained to identify electrical problems or to switch to the hospital’s emergency power system immediately. After extensive investigation, the root cause was determined to be a ground fault. Even the maintenance technicians who called to fix the outage were not immediately effective as they didn’t have the expert knowledge or equipment to pinpoint the location of the fault. Only after emergency power was restored, the fault was located and replaced with a 300+ meter cable. One of the key concerns of this incident post mortem was that the hospital’s maintenance staff working in the control center was not trained to respond correctly based on technical expertise and procedure. They should have been trained to respond to emergencies and identify potential problems before they occur. 

The common-sense solution to these molehills becoming mountains is quite simple: you need to enact a preventive maintenance timeline and schedule. Planned maintenance mitigates minor issues becoming disasters. Reactive maintenance coupled with under-trained staff is a formula for disaster.
