in building a condominium on land adjacent to a lake, a contractor drove piles into the ground to provide a stable base on which to construct the condominium. although the contractor used reasonable care in driving the piles, the vibrations from doing so caused cracks and other major damages to a nearby building. it was foreseeable that driving the piles, which is not an activity commonly engaged in, created a highly significant risk of physical harm, but there was no physical invasion of objects or particles as a result of driving the piles.
