How to work out the volume of concrete, area of shuttering and bitumen paint area of raft footing
This construction video tutorial provides complete guidance for making calculation of volume of concrete, area of shuttering and bitumen paint in raft footing.
The calculation is done on the basis of the following dimensions :-
Length of the footing = 13.5 meter
Breadth of the footing = 12.5 meter
Depth of the footing = 1.4 meter
There are various columns in footing which are taken as C1, C2 and C3
Size of column will be determined as length x breadth
Size of column C1 = 0.4 meter x 0.4 meter
Size of column C2 = 0.5 meter x 0.4 meter
Size of column C3 = 0.5 meter x 0.5 meter
To determine the size of the footing, the following formula is applied :-
Length x Breadth x Depth = 13.5 x 12.5 x 1.4 meter = 236.25 m3
Volume of concrete of raft footing = Area x Depth = 236.25 m3
To determine the Shuttering Area the following formula is used :-
Peripheral Length x Depth = (L+B) x 2 x D = (13.5 + 12.5) x 2 x D = 72.5 m2
To find out the column area, the following formula is used :-
Length x Breadth x No. of columns
After putting the value, we get C1 = 0.4 x 0.4 x 3 = 0.48 m2
C2 = 0.5 x 0.4 x 3 = 0.6 m2
C3 = 0.5 x 0.5 x 3 = 0.75 m2
Therefore, total area = 0.48 + 0.6 + 0.75 = 1.83 m2
To find out the bitumen paint area of raft footing, go through the following video tutorial.
