Safe distance between 12" san swr line and pile driving operation
Safe distance between 12" san swr line and pile driving operation
(OP)
The bents for a flyover will be supported by 6-18" square concrete piles driven 62 feet in clay soil.
Is there a method to determine the safe distance between the pile driving operation and a 12" underground sanitary sewer line that is about 12 feet deep.

If the sewer is clay pipe, I would drill. If steel, I would be a little bit less concerned but probably still drill unless I were about 5 feet away.
