Well, looking at the prints and not knowing the exact dimensions of the steel used in that column, it had to have come from the 80th floor or below. That is where the major transisition was from box column to I beam construction. There was no concrete inside or over those columns. Edited by JFK, Nov 20 2008, 12:01 PM.
