What do I do when another trade ties cable or pipe to my duct hangers?

Hanger Systems, Rods, Straps, Trapeze & Anchors🟨 CHECK FIRSTV189 answer-gap expansion

📖 Verified core answer

Duct hangers are for the duct system, not another trade’s cable tray. Document it and coordinate removal before your support system gets overloaded, rattles, or fails inspection.

Field verification checklist

Photo the exact hanger/trapeze being used by another trade.
Check whether the added load is pulling rods, bending strut, compressing insulation, or contacting duct.
Check if seismic bracing, access, or inspection visibility is affected.
Identify the trade and location clearly for coordination.
Ask before removing or moving another trade’s installed work.

Ask foreman

Another trade tied cable/pipe onto our duct trapeze at [location]. I checked for bending/contact and took photos. Do you want me to have them remove it through coordination, or do we need to document it for the GC?

Route options

AMake the field correction only if it is within your assignment and the approved method.

BHold and document the condition if the fix affects airflow, access, life safety, pressure class, rated assemblies, equipment, or another trade.

CBring the foreman/detailer the location, what you checked, and what decision you need before cover, startup, or rework.

Do not do this

Do not let added cable/pipe loads stay on your duct supports just because they are convenient.

Why this matters

Extra unsupported loads can cause hanger failure, noise/vibration, failed inspection, and responsibility disputes.

Verification basis

Approved drawings/specs, project coordination drawings, manufacturer instructions/submittals, shop standards, foreman/detailer direction, employer policy, and AHJ/code requirements.
