Reliant is providing critical civil construction services for the U.S. Army Corps of Engineers on the West Shore Lake Pontchartrain (WSLP) Hurricane and Storm Damage Risk Reduction Project. Valued at $3.7 billion, this project aims to deliver 100-year storm surge risk reduction through structural and non-structural features like levees, floodwalls, and pumps.
A sheet pile barrier structure and a pile-supported temporary work platform will be constructed to excavate, dewater, and modify existing utilities such as installing pipe sleeves. Additionally, sheet pile walls will be hydraulically jacked down and installed at a depth of 40 feet to prevent water erosion of the wall foundation. This will involve driving sheet piles underneath six petrochemical lines of varying sizes between 6” and 10” in diameter carrying chemicals under high pressures and temperatures.
The project also includes a pipeline crossing consisting of a concrete T-Wall with a deep foundation involving over 200 18” steel pipe piles driven to a depth of 130 feet for support. The design integrates large clay preloads to expedite soil consolidation beneath the structure. The piles will have steel connectors welded to the top embedded into the base of the concrete T-wall.
