The proposed Kutztown University dormitory building was to be built on a site with soils that were unsuitable for the construction of such a structure. The building is a three-story masonry shear wall dormitory on two foot wide strip footings and slab-on-grade. The loads imposed by the dormitory would have created unacceptable settlement of the uncontrolled fill soils at depth. Although several ground improvement options were available to the client, Menard was able to develop an alternative approach of Controlled Modulus Columns (CMC)® rigid inclusions, that saved the client both time and money.
The footing elevations were below the proposed working surface and set at varying elevations. Accordingly, the ground improvement design and installation would need to accommodate the low cutoff of ground improvement elements or inclusions.
