How to calculate Rcc slab quantities concrete and steel

Question

Steel quanties

Answer 1

U can use to calculate the steel like this,

S.No	Description	Sets	Bar Shape			Rod Dia	Actual Cutting Length of rod	No. of Rods	Total No. Of Rods	Bar Weight			Total	Remarks
										10	12	16
						mm	m			0.617	0.889	1.580	Kg
#347
1	Top haunch	1		1.031	0.176	12	1.383	128	128		157.374		157.374
			0.176
2	Slab Bottom	1				12	2.600	128	128		295.859		295.859
				________
				2.600
3	Slab Top	1				12	4.376	64	64		248.977		248.977
			0.888	|________|	0.888
				2.600
4	Links - Slab	1				10	0.450	640	640	177.696			177.696
			0.100	/________\	0.100
				0.250
5	Slab Distributors	1				10	13.043	28	28	225.331			225.331	Lap Length 50D
				________	_____
				12.543	0.500
6	Chair	1		0.500		16	1.500	9	9			21.33	21.330
			0.200	__|"""|__	0.200
			0.300		0.300

 

Answer 2

It is vary simple process, we need the drawing.

If the area of the slab is known, then multiply it from the the thickness of the slab.

Get the bar schedule (if not prepare a one), we can find the total length of each bar from it. Multiply the area of the bar from total length of the bar and density of it. That is the answer.
