During the inspection today the client says someone else was going to buy it but said that the floor structure wasn’t done right. My client asked me to do some research. I checked it out and the only thing I could come up with was that the 6x6 wood piers were not fastened at the bottom, there were no positive connections between the wood piers and the beam which is composed of 2-2x12s, some of the joints on the beam don’t rest on top of a pier, and there is a lack of nails connecting the two 2x12s together.
The 6x6s are sitting on concrete footings that have been dug out. I’ll admit that span sizing is a weak area of mine (my background is computers, not construction) so it may be I’m overlooking something that is glaringly obvious. I’m thinking the spans for 12 in spacing o.c. is good for the 2x10 floor joists If I could get a second set of eyes I’d appreciate it.
I’ve attached photos and a diagram that shows the layout and some measurements I took.
