Step footing Quantity Survey | Volume Of Concrete | Area Of Shuttering | Area Of Bitumen Paint
1. Step footing Volume Of Concrete Calculation
2. Step footing Area Of Shuttering Calculation
3. Step footing Area Of Bitumen Paint Calculation
F = step‐1 : 0.80m x 0.80m x 0.25m
F = step‐2 : 0.70m x 0.70m x 0.25m
F = step‐3 : 0.60m x 0.60m x 0.25m
C = 0.30m x 0.30m
Solution:
1. 1. Volume of Concrete = Area x Depth
= L
x B x D
Step‐1 = 0.80 x 0.80 x 0.25 = 0.16 m3
Step‐2 = 0.70 x 0.70 x 0.25 = 0.122 m3
Step‐3 = 0.60 x 0.60 x 0.25 = 0.09 m3
Total Volume = 0.372 m3
2. Shuttering
Area = Peripheral Length x Depth
=
(L + B ) x 2 x D
Step‐1 = (0.80 + 0.80 ) x 2
x 0.25 = 0.80 m2
Step‐2 = (0.70 + 0.70 ) x 2
x 0.25 = 0.70 m2
Step‐3 = (0.60 + 0.60 ) x 2
x 0.25 = 0.60 m2
Total
Area = 2.10 m2
3. Bitumen
Paint Area = Peripheral Length X Depth + Top Area ‐ Top Step Area
Step‐1 = (0.80 + 0.80 ) x 2
x 0.25 + 0.80 x 0.80 ‐ 0.7 x 0.70
= 0.95 m2
Step‐2 = (0.70 + 0.70 ) x 2
x 0.25 + 0.70 x 0.70 ‐ 0.60 x 0.60
= 0.83 m2
Step‐3 = (0.60 + 0.60 ) x 2
x 0.25 + 0.60 x 0.60 ‐ 0.30 x 0.30
= 0.87 m2
Total
Area = 2.65 m2
