Remarks

Detailed Design of Raft Foundation

It is decided to select Raft footing since the area covered by the individual isolatd footing is more than

50% of the plinth area.

Foundation is that vital-most part of the structure that supports the superstructures-that is what we deliberately build to

our intent. So,the importance of the well-functioning of the foundation can never be overlooked. Since it always lies bur

Civil engineers often site a famous but frustrating paradigm-the most successful civil engineer is buried not after death

the peak of his profession.

The soil testing is done by the method of SPT(standard penitration test) at the 6 nos at a different part of the below of f

and the Structure to be erected is a six-storied complex and the safe bearing capacity suggested is 70 kN/m2 and thequite susceptible to settlements. So,a raft foundation is not only appreciable but necessary too.
