Quantities of Step|Isolated|Pile -Footings

Step and Isolated Footing Formulas
1. Volume of Concrete = Area x Depth
= L x B x D

2. Shuttering Area = Peripheral Length x Depth
= (L + B ) x 2 x D

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

Pile-under- Footing Formulas
1. Volume of Concrete = Area x Depth
= π/4 x d2 x D
2. Shuttering Area = Peripheral Length x Depth
= 2 x π x r x D
3. Bitumen paint Area = peripheral length x Depth + bottom area
= 2 x π x r x D + π/4 x d2
