I have an issue that I am currently wrestling with, which I thought I would post for some comments/advice.
A private, in-ground pool is being built in a residential back yard. I was called to do an inspection of the bonding prior to the deck concrete being poured. As I walked the perimeter of the pool, I noticed that in two instances, a single clamp had been used to secure two #8 bonding jumpers to the rebar. I do not believe that the clamps are listed for securing two wires. I tugged on the wires to see if they seemed secure. In one instance, both wires seemed to be secure, but in the other case, one of the two wires was able to slide back and forth in the clamp. (I believe this is one reason that the clamps are not listed for more than one wire).
I wrote a red tag and cited the fact that the clamps are not listed for more than one wire. The pool contractor was not present when I did my inspection, and the homeowner was not home, so I left my report at the front door of the house. The homeowner got the report, but didn't pass it on to the pool contractor until after the deck concrete had been poured.
The pool contractor should not have proceeded until he had confirmation that the inspection had been made and that the bonding had passed. But now, what would have been a simple fix has become a can of worms. The contractor wants to do a continuity check to show that the items requiring bonding are in fact bonded. I don't believe that a continuity check will provide reliable evidence that a good, long-term bonding connection has been achieved.
Is there a practical alternative for ensuring good bonding connections other than the removal of some concrete and the installation of new bonding jumpers? Would I be over-reactive, hard nosed, unrealistic, to require this?
