National Gallery of Art

Recently Aeon has been working at the National Gallery of Art in DC with Balfour Beatty/Smoot and CA Lindman on the cleaning and restoration of this iconic Modern masterpiece. At one of the curtainwalls we have been focused on cleaning thousands of little yellow and black streaks from the glass and concrete surfaces. After careful analysis we came the conclusion that the staining was organic in nature and suspected that it might be insect related. NGA brought in an entomologist who confirmed that what we were seeing was indeed spider droppings from a colony of Wolf Spiders living in the curtainwall. Information on the project can be found here.
