Cutter Soil Mixed Wall Shoring and Seepage Cut Off Office Building near Waterfront
This paper will present several aspects of the soil mixed CSM wall installed as part of an office building project completed in 2009 near the Seattle waterfront in an area underlain by fill and loose beach deposits with a shallow groundwater. The project involved construction of a 5-story office building with below grade parking that extends below the groundwater table. Constraints included an adjacent dry cleaner with a groundwater contamination plume, an adjacent railroad track, adjacent main arterial, loose liquefiable soils, and significant long term costs associated with discharging groundwater into the City storm drain system. A perimeter Cutter Soil Mixed Wall (CSM) was proposed by the contractor and selected. The CSM wall acted as a temporary shoring wall, a temporary seepage cutoff wall and a permanent seepage cutoff wall. The paper presents the basis for the wall design, and a description of various construction aspects including the CSM wall installation, tiebacks and dewatering. Field testing, instrumentation and laboratory testing results are described that provided critical data on wall permeability, dewatering effectiveness, wall deformation, and other aspects of the performance.
