As you can see by the answers you have received, it's a costly procedure at
best. There are many structural considerations to take into account, not
just adding additional steel columns (or lallys).

Your best over all approach might be to reconsider how you could lay out the
basement with the existing column in place; perhaps over near a wall or
decorated to partially hide it.

If you still want to remove the existing column and add additional ones, you
have no choice but to hire a local licensed structural or civil engineer and
have him analyze your specific situation. (Remember, even if you sell the
home in the future, you would continue to be responsible for this basement.
Having an engineer sign off on it places the responsibility onto him as far
as the insurance and future lawsuits go.

An excellent summary of the structural issues and future liabilities.

Good show!
