Ok, so went to observe the crawlspace/house and also swung by the building department prior to putting together a proposal for engineering. Turns out that the house was originally designed as a full basement and appeared that the reason that it was built as a crawlspace is due to high...
The outer wall is existing, inner wall is proposed to create a full basement. So joist span would not change. I have seen this done by offsetting the interior wall enough to minimize the impact from the adjacent footer above (1:1 slope) but there are constraints such as hallways in the...
Also, this is the contractor's concept, he knows that what is designed will be a lot different that what he shows.

As stated above, would NOT to try and transfer moment, just horizontal and vertical forces as if the upper wall would be pinned-pinned. I agree that there is probably a footer there and the contractor just didn't find it. I know I would need to add a cantilered footer at the inside wall...
Sorry, now attached...

A builder I work with is looking at converting a crawlspace to a full basement here in Colorado (snow, wind control loading). The attached concept is what he gave me and I am a little leary of the feasibility of this detail actually working. He doesn't want to go full height as there will be...
Mike,
I would like to have seen your calcs for this. : ) Not that remote, just has a long, curvy driveway, so am not sure that precast is the best option for this. I am looking at some longer spans - 25-50' if we can get it.

What type of structural system is preferred these days for earth sheltered roofs? The project I am working on is in a mountainous rural area, will have about 2' plus or minus of earth on the roof, and will be constructed into a rocky hillside. I am thinking either a steel deck/joist/beam...
