An 8-meter clay layer experiences an added stress of 55 kPa at its center. The clay layer extends from the ground surface to bedrock and the groundwater table is found 2 meters below the ground surface. The unit weight of the soil above the groundwater table is \( 16.0 \mathrm{kN} / \mathrm{m}^{3} \) and the saturated unit weight of the clay is \( 18.81 \mathrm{kN} / \mathrm{m}^{3} \). Using the consolidation data shown in the graphic below determine the ultimate consolidation settlement of the clay layer due to the added stress.
