Removal of support in basement

Hi. I'd like to remove a support in my basement that is in the worse possible spot in my woodworking shop. It's driven me nuts and it's simply gotta go one way or another.

You can see from the photos that the post is constructed of four 2X4s. The column supports three 2X10 joists across a 14 foot span. Directly above the joists is the wall between our kitchen and dining room and above that is a bedroom. The 2-story wood frame (colonial style) house was built in 1992.

What I'd like to do is place a temporary (18 inch long) 4X4 perpendicular to and underneath the 3 sandwiched joists. The 4X4 would be supported by 2 temporary jacks at each end of the 4X4. This temporary support would allow me to remove the 2X4 column and allow room to run a engineered I-beam or LDL parallel and below the 3 joists. The new beam would be supported on each end by vertical 4X4's attached to each wall.

Because there's ductwork below the 3 joists, there woudl be a 14-inch space between the 3 joists and the new support. I'd add a few short vertical 2X4's between them to support the joists.

Question - does this sound like the way to remove the column? Is there a better way?

You really need someone to come and look at that for you, removing a post without ALL the details is dangerous, things to be considered are span of floor joists, span of beam, whats on top, single, two or three story? you may need to add new posts which require a footing

Hire a local engineer to review.

Nice workshop, but structural work is not a hobby

I guess I agree. I called a structural engineer awhile back and he charges $145/hour - including travel time. Obviously, that's nothing in comparison to the value of the home and peace of mind but I'd rather not spend $450 for the answer.

If anyone can recommend a reasonably priced structural engineer or experienced carpenter in the Zionsville (Indianapolis, Indiana) area, please let me know.

It was probably done that way, so that a wall could be put in later to divide the Utility space from the downstairs living area. Is there any way that you could post 3 other shots (Left, Right, and Other Direction) from the Table saw to show space on those sides?

Total span

The total span (from wall to wall) is 14 feet.
