Useful-life assumptions
The life-cycle inputs used to forecast when building components may need repair or replacement. They link a current condition assessment to an anticipated capital schedule.
Why it matters
Make the evaluation period, component age, observed condition, and treatment of incomplete records clear. Small changes in the assumed replacement year can shift substantial expenditures into or out of a loan term. The assumptions should remain inspectable.
In practice
A project example
A component expected to need replacement just beyond the assessment period should not be described as having no future cost; its timing simply falls outside that forecast.
