Project Description

CONTRACT NAME: Des Allemands Breakwater Bulkhead Project

LOCATION: Des Allemands (Lafourche Parish, Louisiana)

APPROXIMATE CONTRACT VALUE:  $2,960,000

OWNER: Lafourche Parish Government

Scope of Work

The Des Allemands Breakwater Bulkhead project was an extremely important project for the residents of Des Allemands.  Situated in a low lying area of the state, this waterside community experienced flooding during most high water and storm events.  Cycle was the low bidder on the project to provide a new steel sheet pile bulkhead, which would provide a higher level of flood protection for the community.   This project was designed to utilize land based construction methods adjacent to many close houses and roadways.  Cycle discovered early in the process that Entergy power lines could not be de-energized or relocated to safely allow installation of the sheet piling and associated H-Pile tie back system.  As a result, Cycle got creative.  The Cycle team was able to develop a plan to use a specialized press-in pile system that would allow the piling to be installed with minimal vibration and noise impact to the adjacent residents.  This press-in system allowed for a much smaller footprint of area needed to install the piling.  Finally, Cycle made the decision to drive all of the H-Piles from a floating plant in the Bayou.   Despite these significant changes to the intended operations, Cycle was able to deliver the project ahead of schedule with no cost increase to the owner as a result of the changes.

Cycle installed approximately 1,200 linear feet of bulkhead consisting of 55,000 sf of steel sheet piles and supporting tie back piling and bracing.
