For all intents it was a prefab building using different suppliers for everything from steel to fabrication, even the concrete floors were prefabbed slabs as I had said earlier & was told they were poured. There were also many modifications which cut floors & installed additional stairways between some floors but everything went thru the series of center support from top to bottom & material was decreased at different levels going up. I just wonder now if this method was used in any other buildings & if they are being inspected. http://en.wikipedia.org/wiki/Building_o ... ade_Center

what I found even more interesting was the reference page .!
