If the wall or column under construction is near some other property, it will not be possible to spread the footing to both the sides of War or column. In search case which footing is used?

(a) Simple pad footing

(b) Eccentric footing

(c) Isolated footing

(d) Reinforced footing

I have been asked this question during a job interview.

My doubt is from Foundations in chapter Foundations of Construction & Building Materials

Right choice is (b) Eccentric footing

Explanation: Normally, the footing are so designed and proportion that the centre of gravity of the superimposed load coincides with the CG of the base area, so that the footing is subjected to concentric loading, resulting in uniform bearing pressure. However, it may not be possible to do so and hence eccentric loading footings are applied.
