It looked to me like in the main tower a straight column of glassless windows was there ... and you could see floors where drywall was installed before the window glass panels... did I "see" or understand that correctly? Or are these window glass panels being replaced?
Love the brick coursing patterns on the southwestern podium - will be nice to see the rest of those panels go up! And they used a common brick bond pattern for the podiums of the wellington street buildings - nice touch.
I'm curious how these precast brick panels hold up over the long term. From my memory they are a more recent phenomenon, so I can't think of any buildings that are 10, 15 or so years old to see how they weather. By the looks of the panel edges they are stained or painted, so I imagine the colour will fade over time.
