I live a block away from the construction site at the corner of Bright and Varick. They started using what I assume is a pile driver this morning and I can feel powerful vibrations through the floor despite being a block away. I can only imagine what the houses that are in closer proximity are experiencing. Is there a way to monitor the vibrations to ensure that no buildings are damaged? When School #3 was being built, our walls sustained deep cracks that took a tremendous amount of time (and money) to repair. We don't want to go through that again.
