We were glad to wait for him and his crew. He did our previous move on house and we can't say enough about how professional and how perfect and level his foundations are. He uses this device often to make sure that the blocks are perfectly level and plumb.
We had requested the foundation be about four blocks high on the highest edge, and the foundation crew had to even it out all around. On one corner the blocks are only about two and a half blocks high. They had to build around the iron beams the are still holding up the house.
They also had to build piers under the house to hold it up at critical points.
They left with a beautiful, straight foundation. We called our house movers who came out the next day and set the house down on the foundation. They jacked it up a tiny bit, removed the pilings the beams were setting on and then set it down - corner by corner.
This house had lost most of it's bottom sills when it was removed from it's foundation, so we had to add some 2 x 10 pressure treated boards to the top of the foundation to replace them.
