day 43 plumbing & footers, cement on Tuesday

It is looking more like a house now, instead of a nice compacted pile of dirt. The framing for the retaining wall is what you see all around. The footers for the house have been dug, the plumbing has all been laid. How do you know they did it right? Hmmm. maybe we should measure today? We passed the plumbing inspection. The a/c people come out today to lay the vents for the downdraft in the foundation. The cement should start on Tuesday. The metal building/shop arrived and is in piles on the ground.
