Aircraft Hangar High-Bay Duct Coordination

Aircraft hangars add high-bay work, fire protection, door clearance, and large-air-volume coordination.

Stop if

• This hangar duct is near door/crane/fire protection clearance. Do we verify clearance envelopes before hanging?

Watch out

• Do not hang below required clearance or in moving door/crane paths.

Check

• Confirm door path, crane/bridge path, fire suppression clearance, aircraft clearance envelope, and lift plan.

Steps

• Identify whether this is normal ductwork or a controlled/special condition.
• Confirm door path, crane/bridge path, fire suppression clearance, aircraft clearance envelope, and lift plan.
• Get the current drawing/detail/spec/submittal before changing routing, material, access, or support.
• Bring photos, location, and what you checked to the foreman before closing or covering the work.
