Yeah they do that a lot especially for pole barns. I have 2" pvc run for a sink that is it. Probably hard to tell from the picture but the corrugated pipe is on the outside of the wood forms and will be just covered with dirt eventually.I've been in construction my entire life and have never seen a concrete floor poured after the building is erected. I'm a plumber by trade, watcha putting inside plumbing wise? I hate corrugated drain pipe, especially under concrete.
Around here in Michigan it's typically done with footings, then walls, then the slab last (home construction). Pole barns are typically poured with the poles, perlins and siding in place except for maybe a panel or two for the cement truck chute. Use a couple of tongue and groove 2x6 skirt boards at the bottom for attaching the bottom of the siding on the outside and the form for concrete on the inside.I've been in construction my entire life and have never seen a concrete floor poured after the building is erected.
