EXAMPLE 3.4.1. ESTIMATING WALL FOOTING FOR A WALL

Estimate the wall footing as shown on the plans. CHB thickness is 4" embedded two layers under the ground. Thickness of wall footing is 0.10m. Use class A mixture.


The only given dimension for the wall footing is its thickness = 0.10m. The other dimensions of the wall footing will be standardized (check configuration) from the CHB thickness, that is, the width of the wall footing will be computed as:

                           

                          
                     
                           


Volume method:

               










Per meter length method:  The minimal size of wall footing is 10 x 30. The actual wall footing size is 10 x 20cm. So per meter length method is not applicable.
