I'm interested in knowing how one would go about replacing part of the main beam (basement) of a 1926 house.
I've consulted a structural engineer to figure out the required size/ strength of the new beam (probably steel). He will also be specifying the size of the required column and its footing. I'm currently trying to figure out how the work can be accomplished and would appreciate some input.
The beam to be replaced is made of 3 wooden 3x12. My issue is with the fact that the floor joists are hanging from that beam (as opposed to being supported by it). Sitting on this beam is also a 4-feet section of a load-bearing wall.
I figured that I could support the floor joists with jack posts or some temporary load-bearing wall on both sides of the existing beam, but how can I support the 4-feet section of wall without being in the way of the new beam to put in place?
Whatever I put in place there must be removed in order to put in the new beam, but I can't put in the new beam without supporting that wall... What kind of approach would you suggest to take here?
