Secondary SC (13m): 429 u
The proposed development of the dike involved the installation of stone columns and timber piles to densify the 4200m2 (12m wide section running for 354m from west to east) strip adjacent to the existing FortisBC LNG Plant in Delta, BC. The property is bound by the Fraser River on the North, a commercial lot to its west, and the LNG plant to its South.

The solution ultimately consisted of a combination of Vibro Stone Columns at 28.5m depth using Wet Top Feed methodology and Timber Piles at 13m depth.
The TP, subcontracted to a local contractor, FRPD, was ensuring the lateral stability of the dike in case of an earthquake. They were driven along the northern face of the ground improvement area at every centroid of the SC mesh.
