Building Construction is an Engineering Science, which deals with the technique of construction of buildings.In Building construction, A building is defined as an enclosed space covered by a roof. Buildings in general can be classified into two categories viz. Public Buildings and Resident al Buildings. Public buildings are those which are primarily meant for the use of the general public, such as an office, a school, a college, a hospital, a cinema house, etc , whereas a residential building is only meant either for a single individual or group of individuals, such as an ordinary dwelling house or a bungalow. As far as techniques of construction are concerned, for an engineer both are the same.
In Building construction Every 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.
