Yes, when I said the house would be jacked up, I really didn't mean that
they would elevate it, just that it would be supported by jacks until
support beams (2 parallel, possibly 3, I'm not sure) could be placed and
the house _lowered_ down from the jacks onto the beams. It would rest
there until the foundation was poured and ready for attachment,
presumably to be lowered a tad in the process.

No, I don't think there would be any net lowering at all. The
temporary beams and cribbing would be tight against the floor joists,
and the new foundation would be poured right to the underside of the
new mudsill.
