This paper presents about the high level of excess pore water pressure. The high excess pore water pressure was monitored during pile driving work at saturated stiff to hard soil layer of Pleistocene. This high pressure zone under the pile toe is considered to destroy the soil texture and generate liquefaction soil. From this case study, liquefaction phenomenon is understood to be developed in any type of soil, if the level of excess pore water pressure is big enough to destroy the soil texture.
