Fire-resistance rated construction - the walls, floor/ceiling assemblies, doors, and penetration firestopping that compartmentalize a building - only performs as intended if it's installed exactly to its tested and listed configuration. Building Code section BC 110.3.4 requires special inspection of this construction to confirm that's actually the case.
ECC's inspectors verify rated assembly installation against approved drawings and listed details, checking penetration firestopping, joint systems, and door/frame assemblies for the specific materials and methods their fire rating depends on.
We provide the special inspection reports and progress documentation DOB requires throughout construction, giving ownership and the design team a clear record that fire-rated construction was installed - and verified - correctly before it's concealed behind finishes.
