Around here if the floor is stick built steel columns are typically used (not filled). The columns are set on footings prior to the basement floor being poured. Basement floors are often poured after the house is in the dry. Wood posts aren't used unless the basement will be finished and the posts are part of the framing. They are set on the finished basement floor with a footing underneath.
I believe in pclausen's build that column footings poured separate from and underneath the basement floor could settle at a different rate since the whole house is on a floating gravel foundation. The likelihood of a strong bond between a footing poured and a basement floor poured later is questionable. As constructed, any settling of the foundation will allow the house to settle as a unit. Additionally the weight bearing area is greater than a 2'x2'x12" footing and the house is a relatively light house (no second floor etc).
It appears to be better than adequate construction to me.
Very, very good explanation:thumbsup:
You covered in a few words what we have been bloviating about for days.
Good job.
