Architect and Engineer Misalignment
The electrical team shifted their branch raceway in isolation, but uncoordinated mechanical hot water runs maintained the exact same thermal clash inside the corridor ceiling plenum.
Route the conduit away from the hot water pipe.
Thermal interference.
Conduit moved.
Electrical updated, Mechanical did not coordinate.

Resolution Protocol Analysis
One discipline modifying their model sheet without cross-checking the adjacent engineering layers creates false closure records. When the electrical designer shifted the primary feeder line three feet eastward on sheet E-302, the mechanical plumbing layout on sheet M-204 remained pinned in place, leaving the uninsulated domestic hot water main intersecting the new raceway path.
A unilateral drawing change that fails to verify adjacent trade clearances simply relocates the physical conflict rather than closing it.
Using digital overlay tools in Bluebeam Revu 21.10, the lead quality reviewer superposed the newly revised electrical Delta 3 layer directly over the active mechanical HVAC and piping backgrounds. The digital comparison immediately highlighted overlapping color paths, prompting an immediate status rejection before shop drawing submittals went out.
True coordination closure demands that both disciplines co-sign the spatial modification, publish matching revision clouds, and attach a synchronized multi-layer overlay to the submittal record.
