Thumb Rules for Shuttering Material Calculation

Thumb Rules for Shuttering Material Calculation is explained in detail

Thumb rule to calculate the Shuttering area: 

Shuttering costs 15-18% of the total construction of the building. Shuttering is framed to bring the concrete in Shape. The Thumb rule to calculate the shuttering required is 6 times the quantity of concrete or 2.4 times of Plinth area. 

Suppose, the concrete quantity is 0.5m3 then the shuttering area required is 0.5 x 6 = 3m2 

Components of Shuttering:- 

Shuttering Ply, Battens, Nails are components of Shuttering. 

Shuttering Ply Quantity calculation: 

The shuttering Ply has a length, width & depth of 2.44 x 1.22 x 0.012 

The No. of Shuttering Ply sheets = 0.22 times of Shuttering

 Suppose, the area of shuttering required = 3m

Then the Shuttering Ply required = 0.22 x 3 = 0.66m2 

Battens Quantity Calculation: 

Shuttering batten usually have a length & width of 75mm x 40mm. Batten Quantity = 19.82 x No. of Ply Sheets

if the construction requires 25 Ply sheets, the total quantity of Battens are 19.82 x 25 = 495 Battens

Nails & Binding Wire Quantity in Shuttering: 

75gms of Nails are used for 1m2 of Shuttering 

75gms of Binding wire is consumed for every 1m2 of Shuttering. 

Thumb rule for Shuttering oil Quantity: 

Shuttering oil is used to de-frame or de-assemble from the concrete easily. Total required Shuttering oil is = 0.065 x Total Area of Shuttering 

(or) 

For every 15m2 of shuttering 1 litre of shuttering oil is consumed.

 Example : 15m2 is total area of shuttering, then Shuttering oil required = 0.065 x 15 = 0.975
