We decided on a sixty by one hundred twenty under roof metal building. He had one of his employees make the pad. It's like a table top.
I decided to do it in two pours. The first one will be of the main framework, forty by one twenty. Then I'll do the twenty by one twenty approach on the second pour. This is keep us from needing a pump truck. Besides that the approach won't be laid out to the same specs as the main room.
The pad was so good I decided to have it finished grade for the concrete bed. He had a small trencher which helped with digging the beams. I did the three long beams and the one end. I used his Ford 340 skip loader to remove the tailings. It wasn't that bad and I had help. I used paint to guide the trencher and then I had help making a four inch
cut twelve inches wide.
