Challenge

Provide a cost-effective sheet piling solution that needed to be driven through hard material within close proximity of adjacent buildings (10 coffer cells and perimeter sheeting).

ASAP worked closely with the general contractor to develop a cost-effective shoring solution that followed the construction sequence. Material was re-used thus creating cost savings and installation. The removal of sheet piles was tailored to the general contractor needs. All drivelines were pre-drilled prior to installation to minimize vibration and to allow sheet piles to reach minimum tip elevation. The cell closest to the adjacent building was braced to provide further support to the sheet piling and to limit deflection to unnoticeable levels. The entire operation was completed successfully without any issues pertaining to vibrations and/or settlement to adjacent structures.
