Q$5.(20$P$)$ A $2m2m$ square footing will be constructed with a $1$ m depth from the ground surface. The following soil profile has been determined by the site exploration prior to the construction. The groundwater table is at the ground surface. Laboratory consolidation $($oedometer$)$ tests were performed on the specimens from points A & B$,$ and soils from points of A & B are normally consolidated with the following parameters: $c_{CA}=0\mathrm{.}59,e_{oA}=1\mathrm{.}9$;$c_{cB}=0\mathrm{.}37,e_{OB}=1\mathrm{.}21$

Calculate the total settlement in this soil profile.
