Static field route #1049

TAB says the system is short on total CFM and I need to walk it

Airflow/TAB Impacts From InstallationV136 field-polished

Use a system walk: equipment → main → branches → dampers → devices. Find restrictions/leaks/closed dampers before calling it design.

Field checklist

Start at equipment/VAV and confirm system/tag.
Walk main duct for crushed sections, leakage, disconnected pieces, or wrong size.
Walk branches for closed dampers, bad takeoffs, flex restrictions, and missing seals.
List each issue by room/grid with photo.
Bring a clean punch list to foreman/TAB before retest.

Ask foreman

TAB says this system is short by [amount]. Do you want me to walk equipment, main, branches, dampers, and devices and bring back a punch list?

Do not

Do not wander randomly or blame design before documenting the installed air path.
