Dynamic replacement is a very popular method for foundation treatment. It is quite difficult to answer your question without the knowledge of: (1) Brief introdution of project and site (2) Subsurface conditions (3) Design requirement (4) Groudnwater table Your question is not at all difficult.

E.g. it is difficult to achieve more than 500kPa if CFG is adopted, though you increaase the ratio of replacement .
