Got 4 corners built in 8 hours. Learning surveying pretty well and getting a lot of practice. We needed to pivot the building for clearances. Needed to move one side up 1.5", another side back 1.5". I didn't think pivoting was important so I didn't say anything.
I have a 2nd generation 40 year experience contractor guiding me as I build, I'm posing as the main contractor and he is the support. He's basically teaching me as I go.
So I didn't speak up, and he didn't notice. We got 4 corners in and measured square. When I told him we were off by 5.5" the grin left his face and said "5.5" is tear down, limit's 3". We took a few min to see if we could use various methods to get back to square, but ultimately decided to do it right. Kept one corner and shot everyone off of that. 1.5" left on the front's, 1.5" forward on the right rear.
So that's tomorrow. And I'll need to shoot level as well, again. We're off by 1-2" in every corner and the right rear corner, which has the drain, is the high corner. Go figure.
Note to self, if i know it's going to happen, run it by the pro to make sure it's ok. I'm making all the measurements, I'm good at math and geometry, we lost a half of a day because of me. And I paid for it.
