it sounds like this crew was a bunch of rank amateurs at best. My counters were drilled and cut for the sink at the counter manufacturing facility before they arrived. Of course, lots of measurements were made by the designer for that company ahead of time..
I am sorry to hear this De. Got to be disappointing.. And a little aggravating as well.
Good for your builder calling it out and standing tall for you. Hopefully these folks get their act together, follow directions, take some pride in their work on your house, and get this finished quickly.
Wow...
