Problem $1$: A site is prepared for construction by adding $1m$ of sand and gravel fill, in a section of the site a $3m$ square footing is installed and applies a load of $450kN$ to the soil below. Assume that the fill and footing are placed at the same time. Perform calculations by dividing the clay layer into $2$ sublayers and estimate the ultimate settlement of the footing due to the combined load of the fill and the footing.

Estimate the settlement of the footing with the $2$:$1$ method.

Work shown in figure $2$ is not the $2$:$1$ method and S$=0\mathrm{.}328$ m value is not known if correct.

Write any assumptions made and write down process along the way
