Noise Reduction Progress to Date
To date, the following progress on reducing the night construction noise at Kaufman Hall can be reported:
- Brookfield Properties is developing their weekly work plans to spread the loudest activities across multiple times throughout the day to break up sustained period of noisy work;
- Brookfield Properties is utilizing drill and rock splitters where ever possible as an alternative to using significantly noisier hoe rams;
- Brookfield Properties has installed a 12-foot-high wall around the site instead of the NYC Department of Building's required 8-foot fence;
- Brookfield Properties is placing noise shrouds over the loudest machinery when they are being used;
- Sound attenuation blankets have been placed adjacent to all work areas;
- Sound jackets are being utilized on jackhammers when practical;
- Brookfield Properties has positioned trailers and equipment along the perimeter of the site to dampen sound;
- Brookfield Properties has enclosed the pressure manifold, a machine that generates significant noise, in a sound protection box;
- Brookfield Properties is monitoring sound with a decibel reading machine at the Kaufman Hall roof and loading dock and they have a sound monitor recording noise at street level;
- Brookfield Properties is now providing a schedule of work to FIT on a weekly basis;
- Brookfield Properties has identified a 24/7 representative with telephone and email contact information for registering suggestions and complaints.
- FIT has retained its own sound engineer to record interior noise from numerous residence-hall rooms on different floors. This monitoring will continue based on the construction schedule.
- This website will provide up-to-date information on construction activity and mitigation efforts.
