Supported slab- on-grade with an integral footing - that is a thickened edge. The grade of concrete to be used is M30 and grade of steel is Fe415. Two examples of this failure are.

At the base of footing the allowable soil pressure is 5000psf and base of footing is 5 below the existing ground surface. When footings are to be placed adjacent to existing structure as indicated in figure 411 the line from the base of the new footing to the bottom edge of the existing footing should be 45Or less with the horizontal plane. A foundation in residential construction may consist of a footing wall slab pier pile or a combination of these elements.

Generally footings are designed by following strength design method. 100 Pt from Table 2 of Design Aid 0605. Step-2 Area of footing.
