A $650-kN$ column load is supported on a $1\mathrm{.}5-m$ wide by $2\mathrm{.}0-m$ long by $0\mathrm{.}5-m$ deep spread footing. The soil below is a well$-$graded, normally consolidated sand with $=18\mathrm{.}0k\frac{N}{m^3}$ and the following SPT $N_{60}$ values:

The empirical correlation between Young's modulus $E$ and SPT data can be determined from,

$E={}_0\sqrt[\phantom{2}]{\text{O}\text{C}\text{R}}+{}_1{N}_{60}$

Where ${}_0$ and ${}_1$ are correlation factors can be determined from the following table.
