Airflow/TAB Impacts From InstallationV136 field-polished — distinct TAB/airflow answer

A shortcut that saves five minutes can cost a TAB day. Check airflow consequences before accepting sloppy install.

Field checklist

Name the shortcut: extra flex, tight offset, wrong fitting, closed damper, bad seal, blocked access.
Ask whether it affects airflow, TAB, inspection, or service.
Correct simple install issues before ceiling/insulation hides them.
Document issues that need foreman/coordination approval.
Do not normalize shortcuts just because the duct is connected.

This shortcut at [location] might affect airflow/TAB. Do you want it corrected now or reviewed before we cover it?

Do not treat “it fits” as the same as “it works.”

Airflow problems often start as small install shortcuts that nobody wanted to fix while the ceiling was open.
