I have a question concerning concrete basement walls and backfill according to IRC R404.1.7. If the foundation is backfilled prior to the floor being attached are there any problems, other than the short-term possibility off damaging the wall during the backfill operation?

Steve:
Foundation walls must be supported laterally at both the top and bottom
prior to backfill. This is to prevent any movement/rotation of the wall.
Failure to do this can cause a failure in the wall system. Ideally, the basement slab should be in place and the first floor joist system installed prior to backfill.
