A massive,1.7-million-cu-yd, deep-soil-mixing project is powering up in eastern New Orleans, and veterans of the technique say it’s probably the largest such project ever undertaken.
Joint-venture partners Archer Western Contractors, Atlanta, Ga., and Alberici Enterprises, Overland, Mo., are strengthening a levee maintained by the U.S. Army Corps of Engineers so it can be increased in height to +28 ft from its current +17 ft without widening the base as much as normally would be required. The site is constrained on one side by environmentally sensitive wetlands.
