Thank you I am going to look one up

Unfortunately, structural engineers are big on math, but light on practical solutions. You need a general contractor who is experienced in coordinating his subs.

If you are in Maine I highly recommend TC Hafford Foundations. They REALLY know what they are doing. I don’t know if they go into New Hampshire or not.

Where I am structural engineers not only inspect but also tell you what is needed to rectify the problem and then you get a contractor who does what was reccommended by the engineer. We bought a really old house and the center was sagging the contractor came in and put in a new post with proper footings in the cneter of the basement wall as was suggested by the engineer it worked well but cracked a lot of the plaster and lath on the main floor so be prepared for some issues if your situation is similar to ours

Upload a picture of the beam please if you can.

All the splices that you see must be over the bearing points. You have to replace the lolly columns, the one they use (or if there is more) the one in the picture doesn't belong there.

You need a licensed framing crew to replace the existing beam and install new lolly columns, they will know what to do, this can be done fairly quick you just need a contractor specializing in framing.

Whoever did the work there didn't know what they were doing and they botched everything up.

P.S.

I wouldn't plan to have any parties or too many people at the house, because you don't want to have that floor loaded more than it should be, this has to be fixed right away, because if that beam gives for whatever reason, the middle of the house will cave-in.

There doesn't look like there is a need to replace the beam. String a line on the existing beam from foundation to foundation to see how much it has sagged. You need the appropriate amount of Lally columns installed and possibly footings cut into the floor. I'd replace those screw jack columns too. Easy fix for an experienced contractor.

If there are no issues with the existing beam, and you can get a structural lolly column cap long enough so the beam splices bear over the cap and depend on the load some of them have to be welded to the columns.

Something like this

In any case, they will have to figure out the scope of work in the field, and when I said replace the beam, I meant they need to correct the portions of the beam to make sure the splices are over the bearing points, and it is much easier to do that in comparison adding additional columns, cutting floor, doing footings, etc. Done dozens of repairs like that and replacing a portion of the beam is much easier and faster.

Thank you all for your advise! I have a framer that said he wanted to take out the metal post & jack the beam level and put up 4×4s for 5k. Waiting on a structural engineer to have a look. Here are some more pics. sorry for the mess still trying to do other work to the home

Looking at that block, it looks like the beam was changed, they just miscalculated the seams when they made the girder, the seams end up being off the bearing points. There should also be space around that beam for air circulation and to prevent direct contact with masonry, the ends are usualy wrapped with flashing.

Have your engineer look at it, pretty much he will tell you the same thing and he will tell you how to correct this.

Good luck

I definitely know what to ask about now and know more about what they tell me, dont feel like I'm being going forward! Thanks everyone!!

"he wanted to take out the metal post & jack the beam level and put up 4×4s for 5k"

Instead of installing the appropriate columns in the correct manor? 4x4's is not the answer for sure.
