Dec 19, 2012  The test section includes two test cells installed by the multi-auger method and three test panels installed by the cutter soil mixing (CSM) method. Foundation soils at depth were determined to be too dense for both the multi-auger method and the CSM method. As a result, pre-drilling was required at all of the column/panel locations.
