Update Tuesday: The workers were no doing much more demolition today. Rather they were filling up dumpsters with the debris, which was then hauled away to who knows where.
Update Wednesday: Most of the interior of the south wing is now been removed and the north wall of the south wing is gone. The photo below is taken from the west side of the school, and you can see the last of the modules that is along College Ave behind the excavator.
Update Thursday: When I stopped by today the workers seemed to be on lunch break. I walked along the south side of the building and found this sign amusing. If you look through the window you can see the pictures of the planets that are on the walls of the north wing.
