Consolidation test was conducted on a portion of this soil, and the initial void ratio is 1.800 with a compression index of 0.32. A footing that is 6 ft square is to be constructed 10 ft below the ground surface. The footing exerts a total load of 185 tons, which include column load, footing weight, and weight of soil surcharge on the footing. Required: Determine the void ratio (provide 3 decimal places) after primary consolidation settlement, at a point directly under the centre of the footing.
