evaluation of damaged steel columns
(OP)
I have a W8x28 column with a 3" slotted hole in the web from a forklift - is there reason for concern? It is being used as a 17 ft column and is axially loaded to 100% of it capacity.
Also hav another column with flanges bent out of plane by as much as 2" over a 4 ft length. Comments??

While you are installing them on the damaged columns, you can put some on the ones that haven't been hit...yet.

Timing has a lot to do with the outcome of a rain dance.

The sonotubes are the best idea if the client is okay with them. They will both strengthen and protect the column.
If that is not an option then I would suggest a welded cover plate over the region of damage.

I would be a lot more concerned about the column with the bent flange. In my mind, that's almost like initiating a local buckling failure.

2. If the column has a pre-existing deflection of 2" and the column is loaded to 100% of it's capacity than I would think there is call for concern from the P-delta effects. Have the additional stresses from this deformation been considered in any analysis.
Have I interpreted your problem correct assuming the column appears warped 2" or is it just local damage to the flanges from accidental impact?

Slot in the web is probably not a problem, but I couldn't justify not fixing a known problem. Flange seems like the larger problem.
