Scope and inputs to reconcile
Identify measurement units, drawing scale, vertical heights and the system/material/size classification for each route.
Workflow and checks
Check a second known dimension, trace route segments and add documented rises/drops. Reconcile overlaps between plans and risers before totaling length.
What the output should show
Record sheet/view, measurement units, horizontal length, vertical basis and resulting system quantity.
Exclusions and unresolved decisions
Do not scale not-to-scale schematics or treat perspective isometrics as undistorted plan views. Stock/cut allowances are separate from measured route length.
Documents to share for a quote
Send current PDF/CAD drawings with dimension references and floor/equipment elevations.
