Rate analysis for M20 concrete, hi guys in this article we know about Rate analysis for M20 grade of concrete – calculate quantity and cost, Rate analysis comprise of sum of material cost, labour cost, overhead expenses, contractor profit and cost of equipment or tools. And also know about cost and quantity of cement, sand aggregate & water required for 1 cubic metre of m20 concrete.
Rate analysis of concrete is average an estimate for quotation and billing purpose by mason, supervisor and contractor and for tendering use.
Rate Analysis for m20 concrete :- It is a summary of all the cost involved in doing particular work or unit work like material cost, labour cost, overhead expenses, water charges & contractor profit. For rate analysis, the details about all the operation involved in carrying out the work should be available.
The quantities of materials cement sand aggregate and water are required and their cost should be known and the number of different categories of labours required and the capacity of doing work per labour and their wages per day should be known. These can be known only from the experience of particular work. Concrete structure is generally PCC por making Road, pavement, flooring, basement and etc
Rate analysis for M20 concrete:- Rate analysis for concrete work summary of all the quantity and cost of material, labours overhead expenses, contractor profit charges and water charges. Rate analysis for concrete is comprise of following:-
● 1) quantity and cost of material ( cement sand aggregate and water quantity and their cost)
● 2) water charges ( 1 tanker)
● 3) overhead expenses (3%)
● 4) cost of equipment and tools (2%)
● 5) contractor profit (10%)
● 6) labour rate and cost.
Rate analysis for 1 cum concrete of M20 (1:1.5:3)
M 20 grade of concrete have cement, sand and aggregate ratio 1:1.5:3 in which one part is cement, 1.5 part is sand and 3 part is aggregate. For quantity and cost calculation for m20 grade of concrete we should follow following steps:-
◆ Dry volume of concrete=1.54 × 1 =1.54m3 :- we have wet volume of concrete is 1m3 and we have to convert wet volume into dry volume ,we will multiply 1.54 in wet volume.
Dry volume = 1.54 × 1 = 1.54 m3.
◆ Cement quantity 8 bags cost of Rs 3200:- we know that cement density is 1440 kg/m3 and 1 bag cement weight is 50 kg
Quantity of cement = 1/5.5 × 1.54 m3 × 1440 kg/m3 = 403 kg, no of bag cement for 1m3 m20 concrete = 403/50 = 8 bags cement.
If rate of cement = INR 400 per bag, then cost of 8 bags cement = 8 ×400 = INR 3200.
◆ Sand quantity as 14.8 cft cost of Rs. 740 :- generally sand measured in CFT and 1m3 = 35.3147
Quantity of sand = 1.5/5.5 ×1.54 × 35.3147 = 14.8 cft, so 14.8 cft sand quantity required for 1m3 m20 grade of concrete
If market rate of sand is consider INR 50 per cft, then cost of 14.8 cft sand = 14.8 × 50 = INR 740, so cost of sand for 1m3 of m20 concrete = INR 740.
◆ Aggregate quantity 29.6cft cost of Rs. 1740:- generally aggregate measured in CFT and 1m3 = 35.3147
Quantity of aggregate = 3/5.5 ×1.54 × 35.3147 = 29.6 cft, so 29.6 cft aggregate quantity required for 1m3 m20 grade of concrete
If market rate of aggregate is consider INR 60 per cft, then cost of 29.6 cft aggregate = 29.6 × 60 = INR 1780, so cost of aggregate for 1m3 of m20 concrete = INR 1740.
◆ material cost of Rs. 5680 :- quantity and cost of material required for 1 cubic metre of m20 grade of concrete is some cost of cement sand and aggregate
Sub total cost of material = cement cost + sand cost + aggregate cost = 3200 +740 + 1740 = Rs 5680.
◆ Labour rate and charges Rs. 600 :- consider one mason and 2 helper completed 1 cubic metre of concrete work in 4 hours, labour cost will be Rs. 600
Sub total cost = 5680 + 600 = INR 6280
◆ Water charges of Rs 94:- quantity of water required in concreting work used for preparing of mix and curing, consider 1.5% cost of water, then 1.5% of 6280 = Rs.94
Sub total cost = 6280 + 94 = Rs 6374
◆ Overhead expenses Rs 125:- consider 2% overhead expenses,then 2% of 6280 = INR 131.
Sub total cost = 6374 + 125 = Rs. 6499
◆ Cost of equipment and tools :- consider cost of equipment or tools is 1.5 %,then 1.5% of 6280 = Rs. 94
Sub total cost = 6499 + 94 = Rs. 6593
◆ Contractor profit :- consider contractor profit is 10%, then 10% of 6280 = Rs. 628
Total cost = 6593 + 628 = INR 7221.
● Rate analysis for M20 grade of concrete Rs. 7221 is cost and rate analysis for 1 cum concrete of M20 (1:1.5:3).
