A Large Crane and lots of Heavy Metal

As I arrived at the sight this afternoon, the first thing that I noticed was a rather prominent crane arm extending well into the air. Closer examination revealed the movement of very large floor supports being put into place. This is a huge advance over the wooden beams prominent in the ceiling of the old basement.

Also prominent on the site today is a large number of rust colored metal grids (see above and below). My best guess is that these will be spread over and suspended slightly above the surface of the subfloor. The metal grid will help hold the concrete together and make the entire structure stronger. Once the floor is poured, I imagine the walls can begin to go up and the 3rd dimension will be revealed.
