Resonant Pile Driving - Part I - The Promise & The Reality - Part II - Soldier Pile Installation - Light Rail Transit - Buffalo, New York - 1. Historic Background.

The Resonant, or as it has more commonly come to be known the 'Sonic' Pile Driver, dates back to the early 1960's, when prototypes were produced by Charlie Guild, of Providence, Rhode Island, and A1 Bodine of Los Angeles, California, these were later to be developed into the unit known as the BRD 1000. Based on this initial work, the Shell Oil Companies of Sonico and The Resonant Pile Corporation, produced and operated 30 of these BRD 1000 machines, which were used throughout the U.S.A. and Canada on a wide range of foundation projects. Subsequent to this, Raymond International and G K N, of England, operated units on programs; the G K N units being of slightly modified configuration. In 1973 Hawker Siddeley Canada Ltd., acquired the license for the Pile Driver and related systems with the intent of promoting the use of the machines to install support pilings on the Alyaska Pipeline Project, but this did not materialize due to problems with the oscillator. After radical redesign and field testing of the oscillator system the unit was employed on a number of test projects principally in Northern Canada and Alaska.
