Problem $9/3$

$0-0\mathrm{.}3m$ : made ground

$0\mathrm{.}3-2\mathrm{.}5$ m : Upper brown boulder clay, $E_v=$

$50$ MPa

$2\mathrm{.}5-10$ m : Upper black boulder clay, $E_v^{\text{'}}=100$ MPa

${}_{\text{m}\text{a}\text{x}}$ centre and ${}_{\text{m}\text{a}\text{x}}$ edge of building? Differential settlement $()$ between centre and edge?

Would you consider these values acceptable?

Assume footings founded directly on upper brown boulder clay
