All the piles we had were laid out, using our own digger, in the order they would be picked up by the piling machine and sunk into the mud of the canal. It picked each pile up by grasping it near the middle and located it, then vibrated it down to depth. We didn't have enough piles for the job so the piling company brought their own too.
