Which pilling technique is best for a power plant foundation?

Our engineer’s answer:

It depends on many factors suchas soil conditions, loads from plant structure or neighboring environment. Basedon our experiences, we recommend Hydraulic Jack-in Piling technique for ourseveral plant construction sites instead of conventional pile driving methods.The reason is that those sites located on soft ground area and adjacent toneighboring buildings and factories, so that, to minimize emission of noise,vibration and pollution occurs during the pile driving process, we haverecommended this technique because it meets not only technical requirements butalso environmental protection.
