There's some extensive work being done on the glass panels of the lobby entrance at 4747 Bethesda Avenue. A team was working on the glass-box-design entrance after hours last night. Panels shattering by themselves have been an issue at the new Class A office building previously. It's unclear if that is the reason for the work this time, but it is the same spot as before.
Glass has fallen and/or shattered at many new downtown Bethesda buildings built since the recession, including 4500 East-West Highway, Cheval Bethesda, and the Flats at 8300. The mysterious breakage has been blamed by at least one expert in the field on flawed imported Chinese glass.'
