Gharplanner: What is Foundation



Building Construction is an Engineering Science, which deals with the technique of construction of buildings. A building is de­fined as an enclosed space covered by a roof. As far as techniques of construction are concerned, for an engineer both are the same. Find some detailed information about building foundation.
Definition of Foundation
Building structure has two component parts “One is called; foundation and the other super-structure. Foundation is that part of the structure which is generally constructed below the ground level. It is often confused that foundation is constructed to take up the load of the structure or to support it. but actually this is not the case. No doubt the structure rests over the foundation but it is not supported by the foundation. The foundation transmits the load of the structure to the sub-soil below it, never a larger area uniformly. The word foundation as applied to buildings is defined as the extended base of walls and pillars carried below the ground level, to distribute the load of the structure over a larger area of the-sub-soil.
The Foundation is the most important part of a structure. The strength and stability of the structure depends upon its foundation. If the foundation fails, the super-structure however strong it may be, cannot stand. Hence for a stable structure, a good foundation is essential.
Objects of Foundation
As stated above, the foundations are constructed to keep the structure in position. However the following are the objectives of the foundations:
1. To distribute the load of the structure over a larger area of substratum and prevent overloading.
2. To prevent tilting and over-turning of the structure and increasing its stability.
3. To prevent the lateral escape of the supporting material.
4. To provide a leveled base for the super-structure.
5. To prevent unequal settlement of the soil and super-structure by loading the sub-soil evenly
