(b) Impulsive vibration shall not exceed 0.4 inches per second peak particle velocity or its equivalent in displacement or acceleration, on any one of the three mutually perpendicular components of motion except blasting or pile driving, which shall not exceed 2.0 inches per second peak particle velocity.
(c) All vibration recordings shall be made on the ground adjacent to the closest struc ture neither contractor-owned nor leased.
