Temporary barriers of sufficient height with skid footing and a cantilevered upper portion shall be erected within a short distance from stationary plants,

and at practicable distance from mobile plants. The minimum effective height of the noise barriers should be as such that no part of the noise sources associated with the operation of construction machinery should be audible from the target receptors to be protected. Barriers should have no openings or gaps, and preferably have a superficial surface density of at least ten kilograms per square meter (kg/m2). The locations of the temporary noise barriers

shall be adjusted where and when necessary taking into consideration the locations and type of receptor involved and the machinery intended to be protected. Use of the proposed noise barriers, as other construction site equipment, should take into account the following

standard requirements:

 A minimum of 4.5-meter wide thoroughfare with not less than 4.5-meter vertical clearance to be maintained at all times for the free passage of fire appliances;

 The barrier shall not be located where it prevents access to community facilities, residential areas, and places of work or access routes.

 Provide public notification of construction operations prior to construction works.

 Ensure that sensitive receptors shall be avoided as possible from aggregate crushers, operators, etc. Non vibratory rollers (for compaction) shall be used near sensitive receptors such as schools and cultural resources.

 Ensure that all exhaust systems shall be maintained in good working order; properly designed engine enclosures and intake silencers shall be employed; and regular equipment maintenance shall be undertaken.

 Ensure that stationary equipment shall be placed as far from sensitive land uses as practical; selected to minimize objectionable noise impacts; and provided with shielding mechanisms where possible.

 Schedule operations to coincide with periods when people would least likely be affected; work hours and work days shall be limited to less noise-sensitive times. Hours-of-work will have due regard for possible noise disturbance to the local residents or other activities.

 Adopt the necessary and appropriate measures to minimize noise associated with pile driving.

 Construction activities will be strictly prohibited between 6 PM and 6 AM in the residential areas.
