Do you have room to "build" this beam in place? If so I'd do it that
way.. and the ones that are side by side.. I'd not lag them together
till I got it into position.. if it wasn't too bad to get to..

Yes, there is plenty of room to maneuver the 2x8's into place to create the
built-up beam. I just need to jack up the floor that has sagged so the new
beam will fit where the old one was. :)

Price buying or renting the jacks, plates, etc, and then price having a
floor leveling company do the swapout. Horsing main beams around with few
ways to use any assistace other than maybe a come-along, is hard frigging
work. Those things are HEAVY. Good time to look at whatever holds up the
beam, and upgrade that as needed. Nothing special about the work, other than
making sure the beam and posts are the correct specs. Steel plates on floor,
cribbing or screw columns up to ceiling level, and parallel temporary beams
to catch the load of the floor. (If the lap joints of the floor joists sit
above the beam, you will need to support both sides.) Oh, yeah, got a make a
road to get old beam out and new beam in. (That can get hard if the beam is
longer than the space to the house next door.)
Several of the This Old House projects over the years included beam swaps.
Perhaps their web site has pictures showing a step-by-step.
If this is the centerline beam than runs the full length of house, my
preference would be to replace with steel, sitting on steel columns on
oversize footers puched through the basement slab. Yes, expensive, but it
will Never Sag Again.

Any standard jackpost(s) should do it. Your home building experience
should tell you that.

I'll be watching this with interest. I happen to have a jack supporting a
post beam in my crawlspace that the previous owner left in place. I don't
have any idea what I'm gonna do there, the beam used to sit right at the
location where the french drain he installed now sits. I'll try not to
hijack your thread.
