I am having a house built for the first time and I am concerned about the quality of the foundation. I drove by the house (pile of dirt) this evening to see what had been accomplished and found that the footing of the slab had been dug and poured. I observed that the footing was dug with a back-hoe and promptly poured. There are no wooden frames or moulds that I would expect to see. Additionally the footings for the wrap around porch were dug at about 10 foot intervals and look like holes left by one big scoop from the back-hoe. Is the "unfinished" quality and approach normal? I noticed that the rebar sticking out of the cement has star shaped cracks radiating out from it. Again, is this normal and acceptable? My assumption is that this is typical post tension slab prep work.
