I Guess the Elec. Engineer doesn't trust a clean bonding connection to building steel
Seems to me that the Building Steel would have a much lower resistance than multiple driven grounding electrodes. The E.E.
should have utilized at maximum a bonding jumper cadwelded to building steel and attached to the cable tray.
