Today we will see how to prepare rate analysis for Reinforced Concrete (RCC) work. First step to rate analysis is the estimation of labour, materials, equipments and miscellaneous items for particular quantity of reinforced concrete.

The second step is to determine the component of structure for which the RCC rate analysis is required, as the quantity of reinforcement steel varies with slabs, beams, columns, foundation, RCC Roads etc., though the quantity of other materials like sand, coarse aggregate and cement remain the same with the same mix design (mix proportion) of concrete.

Labour rates for reinforcement work changes with type of structural component as the quantity of reinforcement steel changes. The Quantity of materials like sand, cement and coarse aggregates vary with mix design such as M15 (1:2:4), M20 (1:1.5:3), M25, M30 etc..

Here we will see the rate analysis for 1m^{3} of reinforced concrete.

**Data required for RCC Rate Analysis:**

**1. Estimation of materials:**

Material estimation include sand, cement, coarse aggregate and steel for a particular mix design. Let us consider a mix design of 1:1.5:3 for our estimation practice. The dry volume of total materials required is considered as 1.54 times the wet volume of concrete, due to voids present in sand and aggregates in dry stage. Therefore, for our calculation, we will consider the total volume of materials required as 1.54 m^{3} for 1 m^{3} of wet concrete.

**a) ****Bags of cement required:**

Volume of cement required for 1m^{3} of Concrete =

=0.28 m^{3}

Then number of bags of cement (volume of one bag of cement = 0.0347 m^{3})

== 8.07 bags of cement.

**b) ****Volume of Sand required:**

Volume of sand required = = 0.42 m^{3} of sand.

**c) ****Volume of Coarse Aggregate Required**

Volume of Coarse Aggregate == 0.84 m^{3} of coarse aggregates.

**d) ****Estimation of Reinforced Steel:**

Quantity of steel required depends on components of structure, i.e. slabs, beams, columns, foundations, roads etc. To estimate the steel required, there are two methods.

First method is, when we have the drawing available, we can calculate the total weight of steel required divided by total volume of concrete for different components. This will give us the weight of reinforcement steel per cubic meter of concrete.

Second method is assuming the percentage of reinforcement for different components. Following are the percentage of reinforcement steel generally required per different components. Its values can vary from structure to structure, and can be assumed from past experiences of similar structure.

- For slabs = 1.0 % of concrete volume.
- For Beam = 2 % concrete volume.
- For column = 2.5 % of concrete volume.
- For RCC Roads, 0.6% concrete volume.

Lets take example of RCC Column, where reinforcement required is 2.5% of concrete volume, weight of steel required will be:

=196.25 kg.

**2. Labour Requirement for 1m**^{3} of RCC:

^{3}of RCC:

Labours required are presented in terms of days required by particular labour to complete its work for the given quantity of concrete. Following are the various labours required:

a) Mason: As per Standard Schedule of Rates and Analysis of Rates, One mason is required for 0.37 days.

b) Labours: One Unskilled labours required for 3.5 days.

c) Water carrier: One water carrier required for 1.39 days.

d) Bar Bender: Bar bender requirement depends on weight of reinforcement. Lets consider one bar bender required for 100 kg of steel as for 1 day.

e) Mixer Operator: One mixer operator required for 0.0714 days.

f) Vibrator Operator: One vibrator operator required for 0.0714 days.

**3. Equipments and sundries:**

Equipment and other charges, such as water charges, miscellaneous items, tools and tackles etc can be assumed as some percentage of total cost of materials and labours. Lets say it as 7.5%.

**4. Contractorâ€™s Profit:**

Contractorâ€™s profit depends on place to place, organization to organization and work to work. It varies from 10 â€“ 20%. For our case lets assume it as 15% of total cost of materials, labours and equipments.

We have calculated the quantity of every item in above 1 â€“ 3 steps. For rate analysis of RCC, we need to multiply each quantity with their rates to get the amount for every item of work. Rates vary from place to place and time to time. It is advisable to assume local rates or standard rates of the place.

The sum total of all the four items above will give the rate or cost for 1m^{3} of concrete.

a good guide,thnx a lot

I want to put the amount in UAE dirhams. Therefore please kindly send me the password to unprotect the sheet

Am happy 2 be a quantity surveyor

Very clear information is giving this page Thanks

please tell me missing information,i want became an quantity surveyor sir

athaan enakum theriayala boss

what is 1.54? how it came,please tel me

Wat r da funcsns of coarse aggregate in concrete…?!

with this how can i do rate analysis without shuttering works for concrete items?

can anyone tell us that how i can deduct the steel from concrete and i need the steel in Kg. but i know about this ( fabrication of Mil steel deformed bars grade 40 ) ( total concrete for example 50 c.m 50×7.5 Lbs = 375 pound and 375x 0.453 = 169.875 Kg.) is it correct answer for deduction of steel from any concrete..?? can you guide us …thanks…!

Some missing information but overall good information for beginers

thanks for the update men

short & sweet

around 3% of weight of steel !!!

the excel sheets are awesome !!!! way to go !!!

Please how do I estimate reinforcement steel for drainage and culvert

Sir Julian thanks for this info,very helpful.

very very help full material

good,,,,,work…thanks.

its very useful data,thamks brother

thanks for analysis (rcc) work, but i have esquire! how to estimate 1.54 as factor to consideration of analysis

Very useful subject for Estimation…..tnx a lot

Ya. I presumed that 7850 is the density of steel and not the volume of concrete.

so good,thank you

nice

Gud

where is rate for shuttering? and if we use conveyor system how we will calculate? any one will tell me.

Than x Mr. Mishra

thanks I want information about slab estimation.

do you add wastage in reinforcement steel rate analysis also? how much?

u welcome

Proper things

Very helpful

Data shud be shared owez. Thanx Lt

usefull

nice work

very very good! helps a lot.Thanx.

very very good! helps a lot.Thanx.

very very goo.

Very helpful, Thanks. Kindly let me know that while casting roof slabs & beams, at what locations can concreting be stopped incase of bad weather or any other reason?

1/4 of slab & Beam span and vertical joint should be provide.

greattttt

please expliain first method for calculate reinforced steel.

what abt shuttering rate……

Super, Very Useful to Civil Engineers.Thank you.

Its great………………..

IMRAN BHAI that's for u,,,,,, cutting length of different bars.

main bar & anchor bar = L+18d.

one side bend up bar = L+18d+ 0.42d.

both side bend up bar = L+18d+ 2(o.42d).

stirups = 2(A+B)+24d.

what is 7850?

it is the dencity of steel in kg per meter cube 7850….

ya Mr. professor Akash we 'LL learn if you explain properly..:)

good job wel done.

VERY KNOWEDGEABLE AND IT IS DESCRIBED IN SIPLEMMANNER TO PRQACTICE AND PRATICALIZA.

what is unit of concrete.

M3

I'm doubtful about example that RCC Column where reinforcement required,

Is that possible to 7850 cu.m concrete steel requirement 196.25 kg?

7850 is not quantity of RCC. It is the density of steel..

you r right

Sir this is very useful for my future and all civil engineer's.

nice

thank u sir for this vital information.

Dear Mr.Imran. For getting a cutting length of rebar accurately you should deduct 2d for every 90 deg bend.

Thank you Mr. Raja

Could you please provide lentgh calculation of steel bars with different bends.

cutting length of different bars.

main bar & anchor bar = L+18d

one side bend up bar = L+18d+ 0.42d

both side bend up bar = L+18d+ 2(o.42d)

stirups = 2(A+B)+24d

great

Could you please provide shuttering requirement for different structural components.

gud1!
