The column shown apparently is intended to add structural support to the second floor rear wall, which is set back from the 1st floor wall. I noted several issues, the screw jack does not appear to be welded or disabled to prevent movement, not secured to the beam. Also, I thought it should at least be set directly above the center column supporting the beam. The placement of the column may have been a late construction revision. Home built in 2006. Any input would be appreciated.
