Vibrations caused by the work on Pacific

submitted for neighbor who sent this email directly to communityliaison@atlanticyards.com. "I live at 560 Dean Street. I have experienced severe vibrations in our building caused by the work they are doing on Pacific. I have actually gone outside during the vibrations to see the cause, and it appears that the vibrations occur when they are using the large drill-like machine on Pacific that is shoring up the wall. These vibrations are occurring every day, sometimes for minutes at a time. I am concerned that these vibrations are causing structural issues with our building and the building around us. We are a block away from the construction, so I assume that the vibrations are even work for the buildings closer to the construction site."
