# Simple process to calculate shuttering materials for footing

There are various types of formwork materials can be used for footings. You can use plywood, wooden plank or even steel shutter.

Mostly used shutter materials for footing is wooden planks, plywood or wooden board as those are cheap and widely available.

How to Easily Estimate Shuttering Materials for Footing

There are different types of footings in a building. But, all the footings are different. There should be equivalent types of footings. Initially, it is required to summarize the similar type of footings.

Summarizing footings - Generally, the footings are demarcated as F1, F2, F3? etc.

Presume, there are 10 numbers of F1 type footing, 6 numbers of F2 type footing, and 8 numbers of F3 type footing, etc.

Summarize them all. The same types of footings will be summarized based on the footing layout drawing sheet. It is accessible in the structural drawing book.

Once the counting is done for all types of footings, verify the footing layout drawing to find out whether any footing remains unmarked. If there is any, count it also.

Once this step is completed, you?ll get the numbers of all types of footing.

Now, the total number of footings should be counted in the footing layout drawing by marking individually with the pencil.

It is not necessary, to create formwork for all the footings. As for instance, there are 10 numbers of F1 type footings. The sizes of all these footing are equivalent. If you only create one formwork for this type, that can be used again for all 10 footings. In this way, the cost will be saved significantly.

To reduce the cost, it is recommended to utilize wooden shutter materials for footing instead of steel shutter for footings.

Given below, the detail method to measure wooden shutters materials for the footing of a building project.

Step 1: Work out the Periphery Length of Footing.

Assume, the size of the F1 footing is, 4' x 6' x 1'.

Therefore, the periphery length of this footing will be as follow :-

= (4'+6') x 2

= 20'

Step 2: Work out The Periphery Area of The Footing

The periphery area of the F1 footing is,

=20' x 1' (the height of the footing is taken as 1')

= 20 square feet (sft)

Step 3: Workout Shuttering Materials

Wooden plank or plywood : The periphery area of the F1 footing is actually required area of wooden plank or plywood that is 20 square feet. It is required to include 5% extra while giving order for wooden plank or plywood. Therefore, necessary wooden plank or plywood for our footing is, 21 sft.

Wooden batten: Usually, 3"x 2" wooden batten for the formwork of footings is utilized. To make the process simple for calculating wooden batten, just use a thumb rule that is 2 rft (running feet) per shuttering area. So, required wooden batten for the footing will be as follow :-

= 2 x 21

= 42 rft (running feet)

Nail: Similarly, to calculate nail for formwork, just use a thumb rule that is 0.02 kg for one square foot of shuttering area.

Therefore, the required nail for our example footing is,

=0.02 x 21

=0.42 kg (kilogram).

So, the necessary shuttering materials for one formwork of F1 type footing are obtained. Depending on how many formworks will be required for F1 type footing, multiply the shuttering materials with that number.

As for instance, if there are 10 numbers of F1 type footing and it is necessary to create 3 numbers of formwork for this type footing, required shuttering materials for 3 numbers of formwork for F1 type footings will be as follow:-

? Wooden plank or plywood = 3 x 21 = 63 sft

? Wooden batten (3"x2") = 3 x 42 = 126 rft

? Nail = 0.42 x 3 = 1.26 kg.

In the same way, work out the shuttering materials for all several types of footing for your building project and summarize them all.
