A mechanical pipe route is shown crossing low in front of a switchboard service area. What coordination response best protects the electrical installation?
Correct Answer
A) Reroute or raise the obstruction so the equipment remains safely accessible for operation and service
Electrical equipment access must be coordinated across trades. A low pipe in the service area can block safe operation and maintenance, so the superintendent should resolve the obstruction before installation. Contract boundaries, warning paint, or awkward maintenance workarounds do not preserve usable access.
Why This Is the Correct Answer
Electrical equipment access must be coordinated across trades. A low pipe in the service area can block safe operation and maintenance, so the superintendent should resolve the obstruction before installation. Contract boundaries, warning paint, or awkward maintenance workarounds do not preserve usable access.
Why the Other Options Are Wrong
Option B: Allow the pipe because it is not part of the electrical contract
A GC cannot ignore an obstruction simply because another trade installed it; cross-trade conflicts are exactly what coordination is for.
Option C: The coordinator should paint the pipe a warning color and leave the route unchanged
Warning paint only marks the pipe; it leaves the physical obstruction in the worker's service area.
Option D: Ask electricians to use a shorter ladder during maintenance
Making electricians work around a low obstruction is a maintenance workaround, not a coordinated construction solution.
Memory Technique
Picture a gate on the jobsite; electrical equipment overhead obstructions is solved by the action that leads to Reroute or raise the obstruction so the equipment remains safely accessible for operation and service.
