What is Rate Analysis?

The basis of arriving at a correct and reasonable rate per unit. Work or Supply for a particular item following its specification and detail survey of materials, labour, equipment, etc. as required for the unit work and their prevailing rates may be called as an analysis of rate.

How to Use Rate Analysis of Plaster Work Calculator?

This calculator is used for rate analysis of plaster work. Here we will see Step by step how this calculator works.

Step – 1. Select Area 

First Enter your Rate analysis area in Sq.m as per shown in the below picture.

Step – 2. Plaster Thickness

Enter your Plaster Thickness in mm as per shown in the below picture.

Step – 3. Plaster Ratio

Enter your Plaster work cement and sand ratio as per shown in the below picture.(cement and sand ratio in different cells)

 

Step – 4. Fill Labour Charges

Enter your Labour Charges Rate like Mason charges, Bhisti charges, and Coolie Charges as per shown in the below picture.( Mason, Bhisti, and Coolie Charges in different cells)

 

Step – 5. Fill Material Rate as Per Actual

Enter your Material Rate like Cement and Sand as per shown in the below picture.( Enter Cement and Sand Both are in different cells)

 

Step – 6. Additional Cost in Rate Analysis

Check your Further details like Wastage percentage, Scaffolding percentage, other extra charges, water charges and contractor profit percentage. if any are changed as per your requirement than change in cells that are shown in below cells.

 

Step – 7. Rate of Plaster as Per the Required Area

After Completing above 6 steps final answer given last two cells that’s are Cost of 100 Sq.m. that are shown in below picture. (round off figure also mention)

Step – 8. Print Button for Print Out

if you required print your plastering work calculation you can use print button option.

Rate Analysis of Plastering Calculator

Material Calcultion of Plaster Work

In this Rate Analysis of Plaster calculator calculates material, labor, wastage, and other charges in rate analysis.

Material Calculation for Rate Analysis of Plaster

Material calculation in Rate Analysis like Cement and sand

Cement calculation

Dry Cement mortar volume = 1.33 convert Wet cement. (The Plaster mortar dry volume of plaster decrease volume of dry cement mortar, so 1.33 time of dry mortar)

Wastage of cement mortar 33% (1.33) extra

So, Cement calculation requirement of cement = 1 * 1.33  = 1.33 cu.m,

Multiplay plaster thickmess  = 1.33 * 0.012 (thick Plaster)

= 0.01596 Cu.m

Herer calculation mortar ratio 1:8

The required amount of Cement quantity at mortar = 0.01596 Cu.m. * (1/(1+8))

= 0.01596 * 0.1111

= 0.001772 cu.m. cement requirement

Cement in k.g. = volume * density cement

Cement in k.g. = 0.001772  cu.m. * 1440 (1440 kg/m Density of cement for 50 k.g)

= 0.001772 * 1440 = 2.552 kg of cement of bag requied ment of cement in k.g.

= 2.552 / 50 (one cemnent bag weight 50 k.g. only) = 0.051033 bag

So, 100 sq.m. mortar requirement of cement = 0.051033 bag x 100 sq.m. = 5.10 bag

Sand calculation

Required amount of Sand = 0.01596 Cu.m. * (8/(1+8))

= 0.0142 Cu.m. requierd of sand for 1 Cu.m.

So,

So, 100 sq.m. mortar requirement of sand = 0.0142 Cu.m. * 100 sq.m. = 1.42 cu.m.

Labour for Rate Analysis of Plaster

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. 0.81 of day bhisti, per cu.m.0.27-day coolie, per cu.m. 0.81-day belder, per cu.m. 0.81-day mason, per cu.m. 0.81-day helper, per cu.m. 0.81-day mate  for water curing
