Adjustable steel column is raised too high - can I lower it?
Jacking buildings looks simple, but can be complex. I've done quite bit of it for a non-professional, but I happen to be related to a Licensed Professional Civil Engineer who directed the work I've done. As a brash youngster I often could not quite see why we had to take it so slowly - as a somewhat more experienced adult I grasp the fact that you can break a building by jacking it incorrectly.

With "3 levels of condo on top" you'd be well past "fool" and into "darned fool" territory not to have any such work guided by a Licensed Professional Engineer. It only looks simple.

There's also the pesky possibility that the column is right where it should be and other parts of the foundation are sinking.
