dgillette,
Are your comments specifically talking about stone columns in silt? It appears to me that moe333's question and comments are speaking more generally.

BigHarvey,
The contractor will only install to a 20 m depth from the working platform, however bedrock is deeper than that in some areas. This is anticipated and taken into account in the design.
dgillette,
Your assumption is correct. The stone columns in the silts are just to reduce...
Does anybody have any experience or could point me to a few papers that discuss the effects of stone columns installed into deep (20 m+ thickness) silt with a dense fill layer.
Should the stone columns be installed before the preload in in place or after the preload is removed?
Thanks.
