The site consisted of dense sand to depths of up to 12 ft and soft to silty clays to depths of 12 ft to 70 ft.
Driven piles were considered for ground improvement. However, it was determined that CMCs would be more effective in supporting the warehouse’s footings due to the high bearing capacity. CMCs were also more costeffective than driven piles. Menard installed 2,510 CMCs to a maximum depth of 75 ft. Menard designed a layout of CMCs at each footing to support column loads that ranged from 140 to 160 kips. The design provided for 1 in of post-construction settlement, meeting the performance criteria of the building.
Menard faced everything from flooding (due to a tropical storm) to a closed main entrance (forcing it to use an alternative entry) to a poorly maintained working platform to working adjacent to the existing warehouse. Despite these challenges, Menard met the owner’s requirements for quality, safety and schedule.
For a major expansion to a cold storage warehouse at the Port of NOLA, Menard successfully provided ground improvement by installing CMCs.
