How to Prepare Rate Analysis for R.C.C. Work

Q. Prepare Rate analysis for a RCC work with M15 grade of Concrete.

Solⁿ.:-

            Given: - Concrete grade = M15 (1:2:4)  

                                       Take = 10m³ volume for RCC

Add 52% extra for voids to get dry vol^m. Of Concrete.

Volume of dry concrete = 1.52×10

                                                  = 15.2 m³

Quantity of cement = (15.2/(1+2+4) ) ×1

                                         = 2.17 m³

      No. of bags             = 2.17×28.5

                                         = 61.88 bags ≅ 62 bags (say)

Quantity of sand = (15.2/(1+2+4) ) ×2

                                    = 4.34 m³

Quantity of aggregate = (15.2/(1+2+4)) ×4

                                              = 8.68 m³

Let 1% steel of volume

            Quantity of steel = (1/100) ×10

                                                 = 0.1 m³

W.K.T. Density of steel = 7850 kg/m³

Weight of steel = 0.1×7850

                              = 785 kg 

Quantity of Binding wire = 1% of steel

                                         = (1/100 ) ×785

                                          = 7.85 kg

B. Cost of materials

Sr. No.	Material	Unit	Quantity	Rate	Amount
					₹	P.
1.	Cement	Bags	62	350/-	21700	00
2.	Sand	m3	4.34	1000/-	4340	00
3.	Aggregate	m3	8.68	1200/-	10416	00
4.	Steel	Kg	785	40/-	31400	00
5.	Binding wire	Kg	7.85	50/-	393	00
Total Amount = ₹ 68249.00/-

C. Cost of labours

Sr. No.	Labour	Men (nos.)	Rate	Per(Day)	Amount
					₹	P.
1.	Head Mason	1	400/-	Day	400	00
2.	Mason	3	350/-	Day	1050	00
3.	Male Mazdoor	12	200/-	Day	2400	00
4.	Coolie	20	150/-	Day	3000	00
5.	Bhisti	6	250/-	Day	1500	00
6.	T&P	Lump sum	100/-	__	100	00
7.	Blacksmith	8	350/-	Day	2800	00
8.	Mazdoor	8	250/-	Day	2000	00
9.	T&P	Lump sum	100/-	__	100	00
10.	Carpenter	10	350/-	Day	3500	00
11.	Mazdoor	10	250/-	Day	2500	00
12.	T&P	Lump sum	100/-	__	100	00
Total Amount = ₹ 19450.00/-

Total cost = Cost of materials+ Cost of labours

                    = 68249.00+19450.00

Total cost   = ₹ 87699.00/-

Add 1.5% Water Charges of total cost

                                              = (1.5/100) ×87699

                Water charges = ₹ 1315.49/-

Add 10% Contractor’s Charges = (10/100) ×87699

                      Contractor’s Charges = ₹ 8769.90/-

                                                  ____________________________________________

         Grand total = 87699.00+1315.49+8769.90

                                     = ₹ 97784.39/- (say = ₹ 97785/-)

Rate of work per m³ =   ⇒ ₹ 9778.50/-

Hence Rate of RCC work per m³ is ₹9779.00/-
