Problem $1$

Use the data and soil profile shown below. The construction of the houses can commence on

schedule when consolidation settlement is reached within $6$ months of placing the fill. The fill

comprises of compacted soil with height of $10$ ft and unit weight of $120$ pcf $.$ The total consolidation

settlement due to the applied load from the fill is estimated to be $3$ inches at the ground level $(z=$

$0ft.$ The contractor considers that this can be achieved either by the application of a surcharge

load in the form of an additional layer of fill material, the excess of which would be removed after

the set duration.

Calculate the required surcharge height of the fill material for preloading.
