Formwork shall be measured in square metres as the actual surfaces in contact with the concrete

The formwork or shuttering quantity for the member is measured as per the code of BIS – IS 1200:1982, Part 5- Method of Measurement of Building and Civil Engineering Works.

For Column follow the process

1. Measure the four sides of column at base or in cross-section.

2. Calculate the perimeter of column base.

3. Measure the Colum height.

4. Multiply the perimeter of base and height of column to give the shuttering area of column.

Or other way, add all 4 sides and multiply it by height of column.

For Beam follow the process

1. Take the cross-section of beam and measure the lengths of the two sides and base of beam.

2. Sum the three measurements.

3. Measure the span of the beam

4. Multiply the span length by sum of the three measurements (beam base two vertical sides) gives the shuttering area of beam.

The top side in cross-section of beam is not considered as it will be part of beam.

Or the other way, add the beam height(2 sides) and beam base and multiply it by beam length.

Other important factors to be considered while picking the shuttering quantities.

Answer:Calculation:Cross section I terms of metres (400 200 mm) = 0.4 0.2 m

Width and depth are given in cross section

Area of the framework = (2 0.4 2) + (20.4 0.2) + (2 0.2)

= 2.14

Result:The area of the formwork is = 2.14 .
