Installation of Temporary Retaining Walls in Less than 10-foot Headroom under Interstate Bridges with Pressed-in Pipe Piles
Michael Carter, Blue iron Foundations; Ian Vaz, Giken America Corporation
Summary: This presentation describes how temporary retaining walls were successfully installed in extremely low-headroom conditions beneath Interstate 10 just outside of New Orleans, LA as part of the U.S. Army Corps of Engineers' Hurricane and Storm Damage Risk Reduction Project. It highlights the use of pressed-in, interlocking 36-inch pipe piles installed with a silent, vibration-free piling system that operated with less than 10 feet of overhead clearance. The project demonstrates an effective solution for pile installation in sensitive, constrained environments where traditional vibratory methods are not permitted due to risks to existing structures.
