Reply #38: Could you explain your post in more detail?

What fundamental question do you believe has been resolved?

How did you arrive at your figure of 1,000,000 cubic yards of concrete below ground? Were you planning on just posting a number with no explanation at all?

More than a million cubic yards of dirt had to be removed to make way for the Trade Center's foundations. The excavated earth was placed in the Hudson River adjacent to the site, to create more than 23 acres of new land, land which was donated to the city of New York.

And according to the dimensions that Kevin Fenton previously posted (see Post #6) the entire volume of the "bathtub" would be roughly 1,300,000 cubic yards. Do you feel that the majority of that space was filled with concrete?
