The detail of column and pad footing are as under: 
Size of column: 300 mm x 300 mm.
Live load on column: 900 kN.
Dead load on column: 1200 kN.
Soil Bearing Pressure: 180 kN/m² and Depth of footing as 400 mm
Nominal cover: 50 mm and 20 mm diameter bars for reinforcement
iii. Write the reasons for considering the service loads for dimensioning of the footing and factored loads for calculating the factored soil pressure.
