A view from above
This is a special treat, one of the readers has sent this photo in that shows a view from up above the demolition site. I can't get this kind of vantage point from the street level or from my building, so here's what it looks like directly above. Thanks so much!
In addition, there's some commentary:
They are currently using mini-excavators with pneumatic rock breakers to bore a series of small holes in a grid pattern, then they shatter the concrete so it falls through the re-bar. Very slow work.
