I have a small one level ranch new construction being built now. The other
day I got down to the crawlspace to check it out. I am a bit concerned with
the way the floor joists are supported. Being a layman I don't know if this
is the right way to suppor the joist. Not sure if the joists are supported
The lot slopes slightly from back to front. When the foundation walls were
poured the builder said it was necessary to make a "step" in the wall so the
back is about 12" higher than the front (this way driveway wouldn't too
steep). The joists run in back/front direction so now the back ends do not
sit on the concrete. There are 2x4 studs 16" OC just inside the concrete
wall supporting two pieces of 2x4 as beam. The TJI joists sit on the beam.
The total span from back to front is 32'. Two addtional footings with same
type of posts/beam are in the middle to reduce the spans to about 11'.
Concrete wall is about 3' tall.
Is this the right/standard/acceptable way to support the joists in such a
one-level house on a gently sloped lot? This is quite close to a "spec
house" - nearly everything is "standard" grade. But I am a little nervous,
knowing the back end is not sitting on concrete.

is very small gif file (9KB) but quite descriptive.
Thanks in advance for any input.
