Mmm. I walked by today.
2 questions:
I noticed that there is one type of concrete going down maybe 2 stories, then another type going down maybe 50-60 feet. At least I think it's concrete - it couldn't be granite or original "land" could it? (Yes, much of this area is landfill, right?) And how do they do that? The walls weren't put in after the hole was dug, I don't think. Do they do the walls by forcing concrete into holes that become the walls?
Also, earlier question from poster: Where do they put all that dirt after it's been excavated?
