I used Ed's technique on a Commercial job a few years ago.
The EC was going on his merry way over my objections. Then we got to the final, with the City Inspector in tow.
He looked at the job, I mentioned to him that it wasn't something that I thought was done right.
He said (and I quote) "Nice Catch" and made the EC rip it out and do it right.
A side benefit was that I had no problems with anyone on the site blowing off my comments from that day forward, knowing that they just might need to do it over on their own dime.
