Calculation of Concrete Quantity and Shuttering of Step Footing

Calculation of concrete quantity and shuttering of Step footing

A step footing, a type of foundation in construction, is designed to support structures on uneven terrain. It consists of multiple horizontal tiers, or steps, each providing a stable platform for the building above. This design effectively distributes the load and counteracts the effects of uneven ground, preventing settling or structural damage. Step footings are commonly employed in hillside construction, where the ground slope requires varying levels of support. By accommodating the topography, step footings ensure the stability and longevity of buildings while minimizing the need for extensive excavation or modification of the natural landscape.

Calculation Concrete Quantity Shuttering


In step footing all the steps are square-shaped, therefore its length and breadth are the same.

Calculation Concrete Quantity Shuttering

Length 1st step (L1)= 1.6m

2nd step (L2)= 1.4m

3rd step (L3)= 1.2m

Depth of all steps (D)= 0.15m

Calculation Concrete Quantity Shuttering

Calculation Concrete Quantity Shuttering



Area of footing = length (L1) x length (L1) = 1.6 x 1.6 = 2.56sq-m

Volume of concrete = area x depth (D1) = 2.56 x 0.15 = 0.384cu-m

Shuttering area of footing = 4 x (length) x depth

= 4 x (1.6) x 0.15

= 0.96sq-m


Area of footing = length (L2) x length (L2) = 1.4 x 1.4 = 1.96sq-m

Volume of concrete = area X depth (D2) = 1.96 x 0.15 = 0.294cu-m

Shuttering area of footing = 4 x (length) x depth

= 4 x (1.4) x 0.15 = 0.84sq-m


Area of footing = length (L3) x length (L3) = 1.2 x 1.2 = 1.44sq-m

Volume of concrete = area x depth (D3) = 1.44 x 0.15 = 0.216cu-m

Shuttering area of footing = 4 x (length) x depth

= 4 x (1.2) x 0.15 = 0.72sq-m

The total volume of concrete (V) = Vol. step-1+Vol. step-2+Vol. step-3

= 0.384+0.294+0.216 = 0.894cu-m

Total shuttering = shuttering ar.1+shuttering ar.2+shuttering ar.3

= 0.96+0.84+0.72 = 2.52 sq-m
