If the unit is too noisy after a time of adjustment, will O’Brien and Gere be obligated to adjust it to a level acceptable to the homeowner?
DuPont is required to install the mitigation system so there is not excessive noise or vibration while maintaining the depressurization of the sub-slab. DuPont has used vibration dampeners and remote installations to reduce the noise and vibration of the systems to the homeowner. Since the fan is an electrical device, there will be some noise and vibration, so it will be impossible to eliminate all noise. The installation should be acceptable to the homeowner while maintaining the objective of the mitigation system.
