A LTMP has been proven as the best practice to optimize structural property management. A LTMP implemented correctly will almost immediately start delivering the benefits. Having procured a proper LTMP, is the logical next step to invest in implementing the plan properly.
What can you expect.
You will almost immediately experience a reduction in workload; next you will appreciate the improved quality control, and reduced unit cost of repairs. That is in the first year. By the end of the 2nd year will you realize that the unplanned failures start reducing and a budget surplus. By end of year 3 will your maintenance cost have dropped between 20 and 30 %. At this stage, via the annual LTMP revisions, will pro-active and re-active activities be at normalized levels and the predictive learning start kicking in, further reducing failures , and resulting in more financial and efficiency gains .
It starts with implementing the LTMP well.
Implementing your LTMP has various aspects to it and one of the most important ones is the activity scheduling.
The Book of life itemizes all the planned maintenance that needs to be actioned annually. These are annual cycle recurring activities and non –annual cycle activities to be actioned in a specific year.
The activities from the annual cycle schedule focus predominantly on monitoring and routine maintenance to ensure item/components is and remain in good functional condition. The non-annual cycle activities address selective or general renewal to maximize the life time value (LTV) of structural items/components
The ultimate objective is cost , quality and value optimization. The following activties type are in a LTMP activity framework.
- Monitoring/inspecting activities seeks to validate item condition and inform and enable pro-active, preventative and predictive measures in the scope of the planned & unplanned events.
- Routine maintenance is those activities done pro-actively that ensure sustained & uninterrupted functionality
- Renewal activities are pro-active and seek to minimize life cycle degradation/aging
- Restoration is re-active activities focus ons more intensive mainetance to reverse abnormal degradation/deterioration.
Key principles underpinning LTMP activity scheduling
- Clustering is combining activities of similar type or competency together to actualize scale benefits associated with marginal cost and interruption.
- JIT. This principle means that activities are done just in time, and thus maximizing LTV, optimize cost efficiency and productivity, whilst minimizing wastage. Using the a tolerance indicator can activities be scheduled using a JIT method
