# Construction process & details of reinforcement in column footing

Construction Software

In this civil engineering tutorial, you will get reinforcement details of column footing.

Prior to set up footing, 4 inches PCC bed should be provided. Then covering should be given to all sides with 3 inches thickness to safeguard the reinforcement from rust and provide fire resistance to bars.

After that 4 inches cover block should be provided for the mesh to raise the rebar matrix off the ground in order that concrete can flow below the rebar as well as the erosion of the rebar can be resisted.

The pit size should be 4 feet by 4 feet. It is based on foundation.

The dimension of footing should be as follow:

Length of footing = 4 feet
Breadth of footing = 4 feet
Depth of footing = 1 feet 6 inches

Details of mesh reinforcement:

Size of bar – 10 mm
Spacing among bars @6” center to center
L shaped bend = 4 inches (it is based on corner column)
