What is a key characteristic of corrective maintenance?

The key characteristic of corrective maintenance is that it involves repairs necessary to restore functionality after a failure has occurred. This type of maintenance is reactive in nature, addressing issues that impair a system's normal operations. When equipment or systems break down, corrective maintenance aims to return them to an operational state, ensuring that they can perform their intended functions.

In contrast, predictive maintenance is focused on anticipating potential issues before they lead to a failure, thereby preventing downtime. Scheduling maintenance every month suggests a routine or preventive approach rather than a reactive one. Additionally, limiting corrective maintenance to new construction does not reflect its broader application; it can occur in existing structures and equipment at any point in their lifecycle when maintenance is required.

Thus, the essence of corrective maintenance lies in its focus on immediate repair needs rather than scheduled or predictive interventions.
