Abstract

A pile installation recording system for driven piles and auger cast piles. The recording system records a variety of parameter data received from sensing devices. The parameter data is stored, analyzed, and displayed to provide the operator with accurate and timely information regarding the pile installation. In addition, the parameter data may be stored on removable media, and further manipulated to generate a variety of reports regarding the pile installation.
