Construction Outside the Bedroom Window

I'm going to make a photo blog of the building construction that's going on outside the bedroom window and down a block or two.
I find it amazing that the construction guys seem to be doing all the work without any power tools of any sort. So far, the most advanced equipment they've used is some sort of pump and hose to pour the cement.
I watched them put the floor in on Tuesday. They've spent the rest of the week adding to the steel skeleton that becomes the central pillars.
Kind of hard to tell in the next picture, but you can see some guys walking on blanks between two of the pillars. No cranes - they carry all of this stuff up from the ground.
(you can see a picture of what the building will/should look like at the bottom of the image.)
