1. Raft footing Volume Of Concrete Calculation

2. Raft footing Area Of Shuttering Calculation

3. Raft footing Area Of Bitumen Paint Calculation

 

 

F = 12.5m x 10.6m x 1.40m

C1 = 0.40m x 0.40m

C2 = 0.40m x 0.50m

C3 = 0.50m x 0.50m

 

Solution:

1. Volume of Concrete = Area x Depth

= L x B x D

= 12.5 x 10.6 x 1.4

= 185.50 m³

 

2. Shuttering Area = Peripheral Length x Depth

= (L + B ) x 2 x D

= (12.5 + 10.6 ) x 2 x 1.40

= 64.68m²

 

Therefore column area = L x B x no. Of columns

C = 0.40 x 0.40 x 3 = 0.48 m²

C = 0.40 x 0.50 x 3 = 0.60 m²

C = 0.50 x 0.50 x 3 = 0.75 m²

 

Total Column area = 0.48 + 0.60 + 0.75 = 1.83 m 2

 

 

3. Bitumen paint Area = peripheral length x Depth + top area ‐ Column Area

= (L + B ) x 2 x D + L x B ‐ l x b (Column Area)

= (12.5 + 10.6 ) x 2 x 1.40 + 12.5 x 10.6 ‐ 1.83

= 195.35 m²
