Data drives maintenance and vendor accountability
Building Operators, Contractors
Although a contractor provided routine maintenance and service, this shopping mall experienced an increase in the volume and cost of critical issues in RTUs. This resulted in repeated contractor visits, disruption to normal operations and increased tenant dissatisfaction.
Fault Detection and Diagnostics (FDD) was deployed to identify the root cause of equipment issues. Six RTUs were found to have performance scores less than 60%. This required the maintenance contractor to go onsite and repair mechanical and control issues. Using the customized performance scores, the building owner closely monitored the equipment to verify the contractor’s work. FDD determined that two units were still underperforming. The vendor returned to the site to address the remaining issues and completed the job properly.
Utilizing Switch FDD to develop performance scores, RTUs are continuously monitored and immediately identifies potential risk. With ongoing monitoring of the RTUs real-time condition, alerts are sent when certain indicators (alerts) show signs of decreasing performance or upcoming failure. When this occurs, the building operator will create an Event in the Switch platform. With Events, alerts are recorded, updated, shared, commented on and tracked over time to support the action-oriented side of this workflow, turning analysis into real-world actions and work orders. Once the contractor confirms they have corrected an issue, their work is automatically verified by changes to the resulting unit performance scores.
