May 30 - One day after this image by Red Mars, and the shoring machine shown below has left the site - shoring has been completed, and excavation is fully underway, with dump trucks arriving and leaving the site in a steady stream.
From today. It is getting to the fun/serious part of constructing this thing. With large sites, it would take ~ 4 months to excavate 4 levels so we will see how fast this progresses given the small lot and tight location they have to work with. In any event, we should see a crane popping up before Xmas
