Recent developments in dynamic pile testing

During the last couple of years various specifications on High Strain Dynamic Testing and Rapid Load Testing were reviewed and issued. Because of this activity it seems appropriate to determine what developments have taken place and also to think strategically about future developments of these testing methods. In this paper a summary of these aspects will be presented with the objective to inform about new developments and to guide the development of a new generation of tools that will allow practitioners to perform more accurate testing of the foundations, whether with High Strain Dynamic Testing (HSDT) or Rapid Load Testing (RLT).
