Archer Western-Alberici Joint Venture was tasked by USACE to reconstruct, elevate, and reinforce more than five miles of levee outside of New Orleans. The project is a part of the federal government’s efforts to protect New Orleans from hurricanes.
The team also constructed more than 2,000 lineal feet of concrete flood wall. In addition, the team raised the elevation of the levee from an average of +14 to +26 feet using approximately 1.7 million cubic yards of clay embankment in an 18-month period.
Soil below the levee was strengthened through the use of deep soil mixing; a technology that uses large augers to drill holes in which cement is mixed with the soil to create a column of soil and cement that is left in place.
