A clay sample was tested under your supervision as a Project Engineer in charge of a small apartment complex. The borings show the stratigraphy shown below. As a cautionary design principle your company decides to do a primary consolidation settlement analysis to give recommendations to the client. Per building code specification, a maximum settlement due to primary consolidation of 1 inch is permitted. The data collected from the laboratory consolidation test is shown below on the tables. Find the void pressure plots, the swell and compression index, the preconsolidation pressure, OCR, say if the clay is normally consolidated or overconsolidated and find the primary consolidation settlement. Hint: Remember to calculate effective stress and increase in the stresses caused by the footing load. (
