Engineer says design is wrong but contractor says install is wrong
Stay factual. Your job is to document what is installed, what the drawing/submittal shows, and any deviations or field directions - not to settle the design dispute.
I can document what is installed versus what the approved drawings show. Do you want photos, sizes, tags, and any known deviations packaged for the PM?
Watch out
Do not argue design liability in the field or invent missing documentation.
Check
Collect photos of installed route, sizes, dampers, devices, and access.
Compare installed work to approved drawing/shop drawing/submittal.
List deviations with dates and who directed them if known.
Give foreman/PM a clean factual package.
Let PM/engineer handle responsibility questions.
