Close to 27 piles will be installed at the margin of the Terminal 5 wharf. Twelve of the 27 piles will be installed using “vibratory methods” according to the Port. The remaining fifteen will be installed using both vibratory and impact pile driving methods. That second method will produce sound that will carry to surrounding areas.
