How to Calculate Cost and Quantity of 1000 Sq.ft Concrete Slab?

Cost and Quantity of 1000 Sq.ft Concrete Slab

1000 Sq.ft = 92.93 Sq.mt.

Thickness of Slab = 0.150 Sq.mt.

Volume of Slab = 92.93 X 0.150 = 13.939 cu.mt.

Beam Volume = 20% of concrete Vol. 

                       =13.939 X 20/100 = 2.7878 cu.mt.

Total Slab Volume = 13.939 + 2.7878 = 16.768 = 17 cu.mt.

We know :-

M20 Grade of Concrete (1 : 1.5 : 3) 

Concrete Quantity of 1 cu.mt.

Cement = 8 bags 

Sand = 15 cu.ft 

aggregate = 30 cu.ft 

1 cu.mt Concrete Cost =  4,550 Rs.

So :-

M20 Grade of Concrete (1 : 1.5 : 3) 

Concrete Quantity of 1000 cu.mt.

Cement = 17 X 8 = 136 bags 

Sand = 17 X 15 = 255 cu.ft 

aggregate = 30 X 17 = 510 cu.ft

1000 cu.mt Concrete Cost =  77,350 Rs.

Steel Quantity = 1% of concrete Vol. 

                        =17 X 1/100 = 0.17 cu.mt.

1 cu.mt. Steel wt.= 7850 kg.

0.17 cu.mt. Steel wt. = 1334.5 kg.

Steel Rate = 45/kg. 

                  =1334.5 X 44 = 58,718 Rs.

Total Cost of 1000 Sq.ft. Slab.

=77350 + 58718 = 1,36,068 Rs.
