The first objective of this research is to investigate, (1) attenuation of potentially damaging pile driving vibrations with distance and depth, and (2) the effects of distance and age on the quality of concrete exposed to pile driving operations.

The second objective is to use the supporting data to provide recommendations that would enable WisDOT to better define how pile-induced vibrations from different hammers affect the quality of concrete with distance and depth.
