We are excavating our half basement and need to replace the support posts with new ones on new footings. The problem is that 2 of the 3 posts also extend to the 2nd floor. We can't just jack up the joists with temporary shores as in most cases because the beam would be unsupported.
The post goes from the footing block straight up to the 2nd floor and would not be supported by the joists except by nails around it.
This video shows it in the first part.
