Combined Isolated‐footing Quantity Survey | Volume Of Concrete | Area Of Shuttering | Area Of Bitumen Paint

1. Combined Isolated‐footing Volume Of Concrete Calculation

2. Combined Isolated‐footing Area Of Shuttering Calculation

3. Combined Isolated‐footing Area Of Bitumen Paint Calculation

Footing dimension:

Bottom dimension: L1 = 0.85m; B1= 0.85m

Top dimension: L2 = 0.50m; B2 = 0.50

Depth of Footing = 0.91m

C 1= 0.35 x 0.35

C 2= 0.40 x 0.40

Solution:

1. Volume of Concrete = Area x Depth

Part‐1: = L x B x D

= 2.40 x 1.0 x 0.45

= 1.08 m3

Therefore Average length "L" = (L1 + L2)/2

= (2.80 + 2.0)/2

= 2.40m

Therefore Average Breadth "B" = (B1 + B2)/2

= (1.20 +0.80)/2

= 1.0m

Volume of Concrete = Area x Depth

Part‐2: = L x B x D

= 2.80 x 1.20 x 0.25

= 0.84 m3

Total Volume Of Concrete For The Footing = Vol. Of Part‐1 + Vol. Of Part‐2

= 1.08 + 0.84

= 1.92m3

2. Shuttering Area = Peripheral Length x Depth

Part‐1:

= (L + B) x 2 x D

= (2.40 + 1.0) x 2 x 0.45

= 3.06 m2

Part‐2:

= (L + B ) x 2 x D

= (2.80 + 1.20 ) x 2 x 0.25

= 2.0 m2

Total Shuttering Area For The Footing = Area. Of Part‐1 + Area Of Part‐2

= 3.06 + 2.0

= 5.06 m2

3. Bitumen Paint Area = Peripheral Length X Depth + Top Area ‐ Column Area  Part‐1:

= (L + B ) x 2 x D + L x B ‐ L x B (Column area)

= (2.40 + 1.0 ) x 2 x 0.45 + 2.0 x 0.80 ‐ (0.35 x 0.35 + 0.40 x 0.40 )

= 4.3775 m2

Bitumen Paint Area = Peripheral Length X Depth Part‐2:

= (L + B ) x 2 x D

= (2.80 + 1.20) x 2 x 0.25

= 2.0 m2

Total Bitumen Paint Area For The Footing = Area. Of Part‐1 + Area Of Part‐2

= 4.3775 + 2.0

= 6.3775 m2
