“…The specifications were discussed and modified to ensure that a quality end product was delivered. The preconstruction also included a Bench Scale Test that is explained in detail by Bertero et al (2012). This process was a definite asset to the project.…”

“…Due to several factors, the required Validation portion of the project did not start until November 24, 2009 and the DMM was to be complete by March 30 2011. The Validation Phase was to install test elements in 5 different areas spaced equally along the levee to insure the parameters selected for the DMM would produce acceptable results (see Bertero et al 2012). It was originally intended that all 5 areas of the Validation phase were to be completed before actual production started.…”

Although the Deep Mixing Method (DMM) had been applied in the United States since 1986, it was not until the mighty efforts required to quickly and reliably rebuild the levee system in the aftermath of Hurricanes Katrina and Rita that it was used in the New Orleans area. Whereas the soils had long been judged to be amenable to DMM, other traditional methods of ground engineering had previously been used. With what in hindsight can be seen to have been a singularly astute decision, the U.S. Army Corps of Engineers, New Orleans District (USACE) commissioned a full-scale DMM field test in typical New Orleans conditions at the beginning of the decade. Though the test was very successful in all regards, the concept of using DMM in routine construction projects was shelved since it was perceived to not be cost effective. However, the technical and scheduling challenges of the Task Force Guardian projects in 2006 overcame this perception and, from that time onwards, there has been a virtually continuous succession of DMM projects, using both Wet and Dry Methods. This path has culminated in the huge project at Lake Ponchartrain, LPV111, the largest DMM application yet conducted outside Japan.
