Total Length of Beam=106ft.
Let, Proportion=1:2:4
Therefore, D=(3÷8)×(1÷12)=0.03125
Length of Tensile Bar=Length+2×10D
=106+2×10×0.03125
=106.625ft
Total M.S work=(3^2÷24)×106.625×3
=119.95 Pound
=0.54 Quintal
Sum Of Proportion=1+2+4=7
Total R.C.C work=106×(5÷13)×(5÷12)
=18.4 ft^3
Dry Volume=18.4×1.5=27.6ft^3
Requre of Cement=(27.6×1×0.8)÷7
=3.15bags
=4bag
Require of Sand=(27.6×2)÷7
=7.88ft^3
Require of Brick=(27.6×4×9)÷7
=141.94Nos
=145Nos
