 Best st pra racti ctices ces on the const struc ructio ion si site:

• Equipment and staging areas shall be located away

from noise-sensitive receivers

• Minimize high impact devices such as jackhammers

and hoe rams

• Utilize lower impact devices such as concrete crushers

and pavement saws

• Refrain from idling of equipment
