A $500mm500mm$ square column supports a live load of $1000$ kN and a dead load of $1400$ kN $.$ The column is to be supported by a rectangular spread footing, with its width limited to $2\mathrm{.}5$ m and the bottom of the footing located $1\mathrm{.}8m$ below the ground surface. The allowable soil bearing capacity at the base of the footing is $220$ kPa $.$ The soil above the footing has a unit weight of $17k\frac{N}{m^3},$ and the unit weight of concrete is $23\mathrm{.}5k\frac{N}{m^3}.$

For the materials, use:

Concrete compressive strength, f$\text{'}$c $=28$ MPa

Steel yield strength, fy $=275$ MPa

Design the dimensions and reinforcement of the footing, using $25$ mm diameter main bars.
