Re: Installing engineered beams
Yep ---- steel beams are usually my first choice for situations like yours.

In a retrofit situation an under mount beam can work just fine aesthetically and simpler to install---- depending on the depth of the beam ---- typically steel will tend to be not as deep as compared to wood.
This way the beam can be put into place from the inside of the space without ripping the roof open or tearing too much of the ceiling out.
One way to carry the beam point loads down to the foundation ----- set the support column in the exterior wall at one end ------ set the beam on this column ------ lift the other end of the beam and set the other column.
Or ------- you can set your support column on the inside of the exterior wall. This can be a little easier to install the beam since you will have the depth of the framing to push the beam back to allow some wiggle room in setting the other end into place ----- requires only a pocket cut in the wall.
However --- this would likely require to set a support column all the way down to a footing if there is a basement or crawl space underneath ---- for the point loads ------ depends.
Of course temporary support walls will be in place while removing the bearing wall and setting the beam in place.
Just a thought.
