The Challenge
Install a sheet pile wall in pure rock
For Contractors
The contractor contacted us when the test piles for the originally designed king pile system were not able to be installed. Our team quickly identified and mobilized a readily available O-Pile® 102-978 (DTH) domestic pipe sheet pile system that could begin delivery within 30 days.
For Engineers
Mott MacDonald confirmed the general calculation to include permissible deflection for the O-Pile® in X70 steel to replace the lower grade king pile system that could not be installed.
For Owners
The O-Pile® 102-978 was ordered by the contractor and delivered as promised with a performance guarantee ensuring the project would not be delayed due to the lack of sheet pile.
