In the context of a LTMP(long-term maintenance plan) are deferred activities associated with the Activity framework that underpin the LTMP. More specifically with unplanned or re-active activities (failures/Breakages), that are event-driven .
Deferred maintenance is generally referred to as the practice of postponing maintenance activities such as repairs on both real property (i.e. infrastructure) and personal property (i.e. machinery) in order to save costs, meet budget funding levels, or realign available budget monies.
Differentiating between non-deferrable and deferrable events allows us to evaluate and consider cost optimization .
- A non-deferrable activity is usually associated with higher cost as it needs to be done immidiately as a once- off event.
- A deferrable event allows for clustering and thus scale benefits and thus reduced cost .
For example. A shifted or failed gutter section needs to be repaired or replaced.
Considering certain factors , will render this event deferrable or non-deferrable
- If the structure is stable with no safety or structural risk can the repair be deferred and be incorporated into the annual maintenance event. This has a direct cost saving.
- If structure is unstable and thus a safety and structural risk due to the fact that it can fall and injure a person, or it can damage adjacent infrastructure or escalate the defect, then it renders the event non-deferrable and thus needs to be attended to immediately.
- Consideration can however be given to possibly accelerate the maintenance event to the repair event
