When I saw this operation at the Louvre Pyramid I wondered if I.M. Pei, the designer, had ever considered how the 673 panes of glass would be washed. I’ve since discovered, according to Wikipedia, that it was suggested that the structure include a spire to simplify window washing. Pei objected.
I guess if you’re a world class architect and have a cool vision you let someone else worry about these things. This looks like a tricky job.
Special Note: Celebrating Veteran’s Day today with thanks to the men and women who have served and are serving in the U.S. Armed Forces. I’m grateful for their sacrifices, which are many, great, and often taken for granted.
