What Travel Distance does
A measured route record with selected table value, margin and calculation trace.
How it fits into the workflow
- Select the building-use and direction context.
- Record the route as measured segments from the relevant start point.
- Review the matched table row, margin and limitations with the fire strategy.
Where it can save time
Segmented route entry keeps the measured path, selected context, table value and margin together. That makes early option comparisons easier to reproduce and highlights routes that need specialist attention sooner.
Compliance and professional limits
The England mode references Approved Document B and the US context can be reviewed against the selected IBC model-code provision. The tool is an early screen, not a complete means-of-egress, fire strategy or locally adopted code assessment.
Professional boundary: This is an early life-safety screen, not a complete means-of-egress or project fire-safety assessment.
In summary
Travel Distance is most useful when its saved output remains connected to the project decision and is reviewed within the limits described above.
