Your last pics reminds me... They are (finally) completely remodeling the main Engineering building - ENB. The first floor is completely gutted and tarped off. Everything has been ripped out: restrooms, classrooms, even ceilings and floors. Looks like they are doing something similar to how they are remodeling the interior of Cooper Hall. They had a rendering of it, but i failed to take a pic of it. But it looks like a big upgrade.
