I need to poll my peers on this one, so please, serious replies only.

My policy is never to charge for any call that asks me to check my work. I'd much rather go to the site and check, to be sure. I want everyone to feel free to challenge what I did, because that keeps all sides safe. The slightest hint of a suspicion that it might be wrong, I want to know so I can check it immediately. The last thing I want is for anyone to keep quiet while the cost of fixing the problem skyrockets.

Earlier this year I did a topo in a parking lot so they can rebuild the site. Yesterday the client said the layout surveyor had run from the bench mark to the site, and I was off by about three feet. I went out, set up, shot two City of Tucson benchmarks, and my site bench mark. Everything matched within 0.01 feet, which is plenty good enough for a parking lot. I suspect the layout surveyor ran from the bench mark on the west end of the bridge, but used the elevation of the bench mark on the east end of the bridge. That difference is about 3 feet.

Today the client let me know the other surveyor had admitted his error. The client asked me to send him an invoice for checking the work. I explained my policy and emphasized it was for our mutual benefit and protection, but he still wants an invoice. 

What would you do?
