# Rate Analysis of Concrete • Rate analysis of concrete used of reference book IS Code 1200 part 2 (IS Code 1200 part 2 used for measurement), IS Code 2212, and CPWD Part 1.
• All calculations of concrete for rate analysis. This calculation calculates of cement, sand, concrete (Concrete = Cement + Sand + aggregate mixture this call concrete) for materials.
• Concrete is used a sum different proportions 1:0.5:1, 1:1:2, 1:1.5:3, 1:2:4, 1:3:6 etc.(1 cement: 5 Sand: 10 Aggregate). This quantity estimation of concrete is required for the rate analysis.

Important Point

## Important Point in Rate Analysis of Concrete

In this Rate Analysis of Concrete calculation of material, labor, wastage, and other charges in rate analysis.

### Material Calculation for Rate Analysis of Concrete

Material calculation in Rate Analysis like Cement, sand, and aggregate

#### Cement calculation

Dry Cement mortar volume = 1.25 convert Wet cement.(The concrete mortar dry volume of concrete decrease volume of dry cement mortar, so 1.25 time of dry mortar)

Wastage of cement mortar 22 % (1.25) extra

So, Cement calculation requirement of cement = 1 x 1.25 x 1.22 = 1.52 cu.m,

Herer calculation concrete ratio 1:5:10

The required amount of Cement quantity at concrete = 1.52 Cu.m. x (1/(1+5+10))

• = 1.52 x 0.0625
• = 0.095 cu.m. cement requirement
• Cement in k.g. = volume x density cement
• Cement in k.g. = 0.095 cu.m. x 1440 (1440 kg/m Density of cement for 50 k.g)
• = 0.095 x 1440 = 136.8 kg of cement of bag requied ment of cement in k.g.
• = 2.736 / 50 (one cemnent bag weight 50 k.g. only) = 2.74 bag
• So, 10 cu.m. concrete requirement of cement = 2.74 bag x 10 cu.m. = 27.40 bag

#### Sand calculation

Required amount of Sand = 1.52 Cu.m. x (5/(1+5+10))

• =0.475 Cu.m. requierd of sand for 1 Cu.m.

So,

• So, 10 cu.m. concrete requirement of sand = 0.475 Cu.m x 10 cu.m. = 4.75 cu.m.

#### Aggregate calculation

The required amount of Aggregate
= 1.52 Cu.m. x (10/(1+5+10))

• =0.95 Cu.m. required of sand for 1 Cu.m.

So,

• So, 10 cu.m. concrete requirement of sand = 0.95 Cu.m x 10 cu.m. = 9.5 cu.m.

### Labour for Rate Analysis of Concrete

As per calculation of rate analysis in labor consumption per Cu.m. requirement as per our experience or CPWD book, this book public by Central Public Works Department, Government of India for easy calculation of the rate analysis, etc.

As CPWD Mate per cu.m. 0.27 of day bhisti, per cu.m.0.6-day coolie, per cu.m. 0.9-day belder, per cu.m. 0.05-day mason, per cu.m. 0.05-day helper, per cu.m. 0.04-day mate  for water curing

### Extra Work Calculation in Rate Analysis of concrete

Extra Changes in rate analysis as per below

• Scaffolding 1% Extra
• Transportation Cost 1%
• Other Charges 2 % Extra (Electrical, and site extra expense)
• Add for Water Charge @ 1% on Items Marked
• Add for Contractor’s Profit @15% on Items Marked

FAQ

### Rate Analysis for Concrete

• Quantity of material and Its cost.
• Labour cost.
• Cost of equipment or Tools and plants( 1.5%)
• Water charges (1.5%)
• Overhead expenses (2 to 5%)
• Contractor profit (10%)

### Rate Analysis for Cement Mortar

 Labours for 1m³ No’s Amount Mazdoor 0.75 Rs. 375 Bhisti 0.07 Rs. 28 Rs. 403

### Concrete Rate Analysis

For concrete rate analysis, we need first to organize the data we need for calculations. This includes materials, steel, craft, shuttering charge, and water charge.
