The National Gallery of Art’s East Building in Washington, D.C., is preparing for an emergency facelift. Some of the marble panels on its exterior are tilting outward, indicating problems with its veneer panel support system, according to Deborah Ziska, gallery spokeswoman. The panels are attached to the building’s exterior with stainless-steel anchor and clip supports. Local structural engineering firm Robert Silman Associates recommended the removal of all the gallery’s 16,200 panels, reinstallation with new supports and installation of new gaskets between panels.
