The weight restriction of the delicate existing pier deck limited significantly the choice of suitable piling equipment.

The ground conditions consisting of loose sands overlying competent sandstone required a bored piling solution that would be capable of penetrating these soils to provide a socket into the bedrock to resist the significant characteristic lateral design actions.

The traditional cable percussive piling rig, weighing only 1 ton and consisting of a light Sykes winch with an attendant mini crane avoided the the need for a jack up barge and crane mounted piling rig and the considerable cost associated with such a large scale operation, providing a viable solution for this charitable restoration project.
