ive been asked if a porta cabin can be jacked up and sub framed under it
to restraighten the structure and also level the building out as well
the structure is something like this and the jacking legs are at full height but still leans and has sagged about 1,1/2" for what i can see it has 2 i beams running the full length of the porta cabin
with the structure holding on the legs only im thinking that the structure can sit on a built subframe underneath it built level then lowered onto the subframe to relevel the whole portacabin
im asking as my idea could be so crap and im not sure if it could be done or not
but thinking in the lines of 2 posts on either side of it with an I beam welded to the top of posts i presume with angles due to load
the i beams would sit on top of the other I beams of the subframe
5/6 posts of the length with tie ins between each post
to restraighten the structure and also level the building out as well
