I'm going back to working on the building (Robot Factory) and giving the robots a brief rest. I managed to dodge security and take some photos of the building exterior for some reference shots. Here is one of the side wall with windows. There are 20 of these window "modules" across (each "module" contains the three large and three small windows) and three rows of them.
I had a measuring tape with me and measured everything that I could find, so my model is close to spec. Of course, I picked the day with the most wind and I borrowed a thin measuring tape, so the only thing I couldn't get was the height of the smaller window, which I estimated (with some sloppy Photoshop measurements) to be rougly a third of the large window height, which works for me.
