Construction Nuisances The goal is to minimize constructions impact on abutting residents and businesses, while moving forward with the work on schedule and within budget.
RECEPTOR CONTROLS When all other approaches to noise control fail a program of control at the receiver should be undertaken.
RECEPTOR CONTROLS Window treatment program A receptor located very close to the noise generating activity.
RECEPTOR CONTROLS Resident with health condition Window treatment program Criteria: Hardship situation ( infant, house-bound person)
RECEPTOR CONTROLS Interior glazed storm sash Window treatment program Measures: Replace window with double pane glass Sliding glass storm door
RECEPTOR CONTROLS Window treatment program Cost guidelines on CA/T project: $800 per interior storm sash $2,500 per window replacement $5,000 total per resident
RECEPTOR CONTROLS Temporary relocation In very special cases temporary relocation may be necessary. California - earthquake repair One case I-15 project (medical) Four apartments CA/T project
COMMUNITY RELATIONS Early communication with the public is
COMMUNITY RELATIONS Establishment of good rapport with the community can provide high benefits at low cost.
COMMUNITY RELATIONS Inform the public of any potential construction noise impacts and measures that will be employed to reduce the impacts.
COMMUNITY RELATIONS INFORMATION Identify the work activity and location. Identify the work hours and the duration of the activity.
COMMUNITY RELATIONS INFORMATION Explain what neighbors can expect, sounds, lights and equipment. A statement of concern about the nuisances and that every effort is being made to reduce impacts is important.
COMMUNITY RELATIONS INFORMATION Whenever possible, crews will point lights away from homes and will also try to move heavy equipment so that back-up alarms are angled away from homes.
