For everyone else, this is what I am talking about. Am I correct in saying that this would NOT be the way to go and that I need a "line" extending the post to the basement floor??

Sorry Harley...I put your image in my post to give everyone else a little view of what I was thinking. Thanks for making my job easier

Since the post lands right on top of a joist....could I get away with adding the wall and not worrying about the smaller beam. This would give support to the joist so that it would not sag.

If you sistered the current joist a couple times you would in fact have a beam....

Sistering a joist is when you stick another joist beside the current one and glue and screw it into place. When one builds a beam, say out of 2X10's typically a layer of plywood is placed in between the two 2x10's, all glued and screwed together.

You could sister the joist in the manner one would build a beam....meaning current joist, glue and nail piece of plywood to it, stick another joist up there glue and nail that to the plywood, you have in effect built a beam.

Now whether or not that beam will be strong enough is a question I can't answer, since I don't know what (wieght) your post upstairs is holding, but that post has a limit, and if the beam i.e. sistered joist and new wall can support the amount of weight that your post is rated for you should be good.

The beam total weighs close to 200lbs but it also helps support the attic. I will search for an answer.

Okay. My biggest problem...and sorry if I already mentioned this, but it is that the place that I need to support the floor joist is near a floor drain where the concrete slopes. I had thought that I could lay a pt 6x6 on the floor and put an adjustable post on top of the 6x6 and and attach to the floor joist. Is this an option?

To be safe I have decided to go ahead with Glenn's suggestion to make sure there is support directly under the beam. Ideas with the sloping floor. Or would a slight slope in a 6x6 post be okay to rest an adjustable pole on?

You could kill several birds with one stone by busting up the area around the drain, diggin down, pouring a footer that is level on top, and then moving the drain......

I think that would end up killing me by doing all of that.
