Foundations should be constructed to satisfy the following requirements
The foundations shall be constructed to sustain the dead and imposed loads and to transmit these to the sub-soil in such a way that pressure on it will not cause settlement which would impair the stability of the building or adjoining structures.
Foundation base should be rigid so that differential settlements are minimized, Specially for the case when super-imposed loads are not evenly distributed.
Foundations should be taken sufficiently deep to guard the building against damage or distress caused by swelling or shrinkage of the sub-soil.
Foundations should be so located that its performed may not be affected due to any unexpected future influence.
Foundations should be such that it can easily carry dead load and imposed load of the structure and transfer the loads to the soil.
Foundation base should be strong enough to reduce the unequal settlement of soil if imposed load is not distributed equally to the soil.
It should have a definite depth so that structure may not be damaged due to expansion or compression of soil volume beneath the foundation.
Foundation should be strong and designed with safety factor so that structure may not be damaged due to unexpected effects.
