I actually am almost on my way out the door, I'll respond in more detail later. (Hopefully tonight.) But I did want to make a few comments.

I seem to remember that the floors on the mechanical floors were thicker than the others (7 inches?). I also remember something about the floors in the cores being thicker. You wouldn't happen to know this off-hand, would you?

I don't know about the mechanical floors, but I seem to remember that the concrete was 5 inches thick within the core. Don't recall the source for that right now though.

OK, the roofs:
1..208...208...0,33...0,037...528,25344
2..208...208...0,33...0,037...528,25344
3..64....330...0,33...0,037...257,8752
4..84500.......0,33...0,037...1031,745
5..120000......0,33...0,037...1465,2
6..67000.......0,33...0,037...818,07
..............................4329

I'm not going to go over the numbers right now - I just wanted to give you a hint on displaying tables. You can use the html <pre> tags to preserve the spaces in your text and make all the characters the same width. For example this code:

[font color="#000099"][pre]
      area   thickness  cu. yds.   total
1. 208 x 208    0,33     0,037    528,25344
2. 208 x 208    0,33     0,037    528,25344
3.  64 x 330    0,33     0,037    257,8752
4.     84500    0,33     0,037   1031,745
5.    120000    0,33     0,037   1465,2
6.     67000    0,33     0,037    818,07
[/pre][/font]

Will result in this:

      area   thickness  cu. yds.   total
1. 208 x 208    0,33     0,037    528,25344
2. 208 x 208    0,33     0,037    528,25344
3.  64 x 330    0,33     0,037    257,8752
4.     84500    0,33     0,037   1031,745
5.    120000    0,33     0,037   1465,2
6.     67000    0,33     0,037    818,07

I did the same thing you did for my first few tables, but didn't really like the result. Just thought I'd share that in case you wanted to use it.

I'm going to leave the spandrel beams for now.

Me too! I don't even know where to start - almost no information except the cross-sectional area for those.

Posted by Kevin Fenton:

Fireproofing of perimter beams:
1,5 (width of beam (14 inches) + width of coating in feet) x 0,3 (width of coating in feet) x 4 (sides of column) x 70 (height of basement) x 236 (number of perimter columns) x 2 (number of towers) x 0.037 (conversion to cubic feet) = 2200.

The perimeter columns of the tower were combined in groups of three above ground in the "trees" and then went to the foundation in a reduced number of larger columns. I don't know the numbers and dimensions off the top of my head.

Posted by Kevin Fenton:

My running total is just over 260,000 cubic feet. Where the hell did they put the rest of it? There must be lots of concrete walls in the basement outside the towers, maybe it's there.

I think it's probably all in those spandrel beams. :)

Actually, I'm not sure about a lot of this yet, but I applaud your efforts to work on this estimate with such limited information available. I hope the results will help answer some questions.

More to come...
