Thumb Rule:
Formula : Covered Area x Thumb Rule
Plywood:
Size = 8 feet x 4 feet
Thickness = 12 mm (1/2 inch)
= 700 x 0.02
= 14 nos.
Wooden ballies (bamboo)
Ballies (bamboo) for Beam bottom plates:
Thickness = 1.5 inch
Formula : Covered Area x Thumb Rule
= 700 x 0.24
= 168 rft.
Ballies (bamboo) for Beam
Beam bottom plates x Thumb Rule
= 168 x 0.5
= 84 nos.
Ballies (bamboo) For slab:
Formula : Covered Area x Thumb Rule
= 700 x 0.16
= 112
Total Ballies (bamboo) = 84 + 112 = 196 nos.
Nails
Formula : Covered Area x Thumb Rule
= 700 x 0.02
= 14 kg
Wooden battens
