What is lifecycle planning?
Lifecycle planning is forecasting the replacement of building assets over a period and the cost of doing so, so that capital can be planned rather than found at short notice.

</figure>It converts an asset register and condition data into a forward cost profile, which is the form in which building maintenance can compete for funding against everything else.
The profile is more useful than the total. Knowing that three major plant replacements fall in the same year is what allows them to be sequenced before they arrive together.
It needs maintaining rather than producing. A plan built once and not updated with what was actually replaced diverges quickly and quietly.
In practice
A landlord deferring a roof replacement for a third year.
Each deferral was rational on its own. The accumulated consequence is water ingress damaging the floor below, which is now two jobs.
Lifecycle planning is the discipline of making deferrals visible as decisions with consequences rather than as savings.
The deferred item that causes collateral damage is the one worth modelling.
What goes wrong in practice
- A plan produced for a funding round and never maintained.
- Replacements carried out and not fed back, so the plan still forecasts them.
- Statutory and compliance-driven replacements omitted from the profile.
