Welcome to the CADTutor forum Rock and thank you for your kind words on behalf of everyone who has contributed in one way or another to a Penn-Foster thread.
I could only take a real quick look but I have a couple of comments.
1. It appears that some vertical rebar is missing in each pier/footing.
2. The siding runs vertically not horizontally (if I recall correctly).
3. It appears that the floor decking is missing. Cannot pour all that nice concrete you are showing without decking on top of the beams otherwise somebody is going to have a big mess on their hands.
4. Depending on which way a "W" shape column/beam is viewed the resultant depiction of it will be different. Looking at the flat face of the flange the web would be dashed. Looking at the same column/beam from a different side one would see the top/bottom edges of both flanges. Understand?
If I get a chance later I'll take a more in-depth look.
