I would call for an engineer in the above case for a few reasons. The beams that were cut are part of the support structure. I believe that there was more than one cut.

An engineer could design the appropriate support corrections to prevent the floor from sagging, or to jack it up into its original place if the floor was sagging. Then, any old "Bubba" should be able to follow the plans. And, I emphasize "Should"!

Here, that kind of work would require a permit and plans to complete. It would also have to be inspected.

I don't care how much it costs anyone in the transaction. I try to do everything I can to make sure that whoever does the repairs, at least my Client knows how it should be done.

I still get paid to be suspicious when I got nothing to be suspicious about!
