A proposed industrial building will carry unfactored column loads ranging from 280 to 1,200 $\mathrm{kN}$ and service loads from 230 to $950 \mathrm{kN}$. The allowable settlements are $\delta_a=30 \mathrm{~mm}$ and $\delta_{D a}=12 \mathrm{~mm}$. It is supported on a cohesionless sand with $\phi^{\prime}=35^{\circ}$ and $\gamma=19.2 \mathrm{kN} / \mathrm{m}^3$. Footings at this site will be at a depth of $2.2 \mathrm{~m}$ and the groundwater table is at $5 \mathrm{~m}$. A dilatometer test run at the site has returned the following modulus profile:
$$
\begin{array}{l|llllllllllll}
\text { Depth (m) } & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & 13 \\
\hline M(\mathrm{MPa}) & 18.3 & 20.6 & 19.0 & 21.1 & 35.2 & 40.0 & 37.3 & 30.1 & 31.9 & 40.0 & 40.8 & 42.0
\end{array}
$$
Prepare both serviceability and bearing capacity design charts, using ASD for ULS analysis. Then, comment on the feasibility of using spread footings at this site.
