For the few that may be curious about the scaredy hole I had put in yesterday...
Cool tool alert. This is what a bad ass concrete saw looks like. This thing gets after it.
It did not take him long to get the hole cut. He cut a few slices on one end only to break them up easily.
The back-hoe operator is a master at that thing. It was obvious he did not just watch a Home Depot video and sleep at Holiday Inn last night. He was amazing to watch. In short order the pit was empty and the trailer was full.
Before the drop in
Just set it down.
They have a simple bar that hold the unit in place and can hold it down or lift it up. They use wedges of wood to position the unit into the center of the hole and big C-clamps to hold the unit down so it does not float up in the concrete.
Squared up, level and ready for 2.5 cubic yards of 3,500 PSI concrete.

After the pour just a little smoothing. than more cleanup with a power washer, and final concrete smoothing, and bolt on the back lid. It comes off with two 9/16th bolts. if for some reason I ever wanted an inspection pit.
Ta-da. The handle slips into the square hole in the bottom right of the photo. It has 4 steps to get to the bottom. They are removable to give us more room once down there. There are two bench seats that run the length of the unit. Now we just need to stock it up and hope we never ever need to use it. I hope it is a total waste of time and money and we never need it, ever.
They started at 11:00 and finished ant 4:00.
