I have updated my Adobe Acrobat from 5 to 7 which does better searches. I don't normally mess with PDF files much. I still haven't found a specification for the concrete in all of these files.

N# is the number of times the word "ton" appears but only in the Metric Conversion Table, it doesn't specify info about the towers.

Someone claims 1-2A pdf pages 103-106 has the info I want but if so it is specified in engineering jargon that I will have to work to decifer.
