Ground vibration data, originating from impact hammers and vibrodrivers and compiled by different research workers, have been plotted in scaled distance form and statistically analysed. A quadratic regression curve rather than a linear regression curve provides a better visual fit to the several data sets. In each case, superimposed on the graphical data points are also the one-half standard deviation and the one standard deviation curves. It is argued that the quadratic one-half standard deviation curves, generated from an analysis of all the reliable vibration information compiled by the authors from impact hammers and vibrodrivers, be used for design of piling operations in order to mitigate excessive environmental vibration.
