TinnerFlow™3rd YearTrade CoordinationRED · Stop / Verify
Stop before flattening or rerouting duct around the pipe. Document the clash, confirm the latest coordination drawing, and get direction on pipe relocation, duct reroute, split duct, or engineered transition.
A pipe installed through a duct route is a coordination problem. Large duct is usually harder to reroute than small pipe, but that does not mean you get to smash, flatten, or detour the duct on your own.
The right move is to document the conflict clearly: trade, system, size, grid, elevation, direction, and whether it was shown on the latest coordinated set. Then the foreman/detailer/super can decide whether the pipe moves, the duct changes, an RFI is needed, or a new detail gets issued.
Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
