1. 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.
2. Foundation base should be rigid so that differential settlements are minimised, specially for the case when super-imposed loads are not evenly distributed.
3. Faundations should be taken suficient1y deep to guard the building against damage or distress caused by sweelling or shrinkage of the sub-soil.
4. Foundations should be so located that its performaced may not be affected due to any unexpected future influence.
