Site backfill is scheduled before the service grounding electrode work has been inspected. What should the superintendent coordinate?
Correct Answer
C) Verify the grounding electrode/bonding work is installed and inspected before it is concealed
Grounding electrode and bonding work can be concealed by site work, slabs, or finishes, so the superintendent must coordinate installation and inspection before cover-up. Memory notes, post-energization installation, or equipment delivery do not replace inspection of the grounding path.
Why This Is the Correct Answer
Grounding electrode and bonding work can be concealed by site work, slabs, or finishes, so the superintendent must coordinate installation and inspection before cover-up. Memory notes, post-energization installation, or equipment delivery do not replace inspection of the grounding path.
Why the Other Options Are Wrong
Option A: Backfill first and document the location from memory
A memory note cannot verify buried grounding work after it is covered and leaves the project with no inspectable installation record.
Option B: The superintendent should install grounding components only after permanent power is energized
Grounding and bonding must be coordinated as part of the service installation; waiting until permanent power is energized is too late.
Option D: The superintendent should omit the grounding review if the transformer has arrived
Transformer delivery is a logistics milestone, not proof that the grounding electrode and bonding work are complete and inspected.
Memory Technique
Use the phrase "problem, control, result" for grounding electrode coordination; the result side is Verify the grounding electrode/bonding work is installed and inspected before it is concealed.
