I think I would weld a piece of flat stock from the base of the steel support along the floor over to the wall, then another short piece up the wall or over to where the GEC emerges and tap it there for a lug.
It's still hard to tell in the picture why they did it that way. Looks like two GECs emerging from the slab, is that correct?
