Best answer
Correct Answer - Option 2 : 50 cm

Concept:-

  • As per National building code (Group 2), Clause 7.1.4, The depth to which foundation should be carried depends on the following principle factors-
  1. The securing of adequate allowable capacity.
  2. In the case of clayey soil, penetration below the zone where shrinkage and swelling due to seasonal weather changes, and due to trees and shrubs are likely to cause appreciable movements.
  3. In fine sands and silts, penetration below the zone in which trouble may be expected from frost.
  4. The maximum depth of scour, wherever relevant, should also be considered and foundation should be located sufficiently below this depth.
  5. Other factors, such as ground movements and heat transmitted from the building to the supporting ground may be important.
  • All the foundation shall extend to a depth of at least 50 cm below natural ground level.
