## Rate Analysis For Gypsum Plaster

Hello friends,

Today in this article We are going to learn, how to do rate analysis for gypsum plaster?

So let’s start

Many brands are available in the market but for rate analysis purpose let’s take an example of gypsum plaster from M/s Saint Gobain offers two different types of gypsum plaster

1. Basic stucco plaster
2. Premixed lightweight plaster (also known as Elite Plaster)

The density of basic stucco plaster is 1000 kg/m3 and the density of gypsum plaster is 700 kg/m3. Here we will consider Elite -90 gypsum plaster which is lightweight plaster as compared to stucco plaster.1 bag of Elite – 90 contains 25 kg of gypsum. The coverage area for Elite-90 is 25 square feet per bag for 13 mm thickness.

For analysis purpose, we will consider the area of 100 square feet of gypsum plaster. First, we have to calculate for 100 square feet area, how many bags of Elite-90 gypsum plaster required.

For 100 square feet area  = 100/25

= 4 Bags

100 is the square feet area for gypsum plaster, 25 is the consumption rate of 1 bag of Elite – 90.

Rate of one bag Elite – 90 is = 250/-

Here make sure that the rate should not contain GST, GST should be extra because anyway at the end, the contractor will be getting the benefit of GST that’s why we have to deduct the percentage of GST.

So, 250 rupees is excluding GST.

Hence the cost of Elite – 90 for 100 square feet area is = 4 x 250

= 1000/-

We will consider 5% wastage = 1000 × 5%

= 50/-

Hence, Total material cost = 1000 + 50

= 1050/-

So this is the material cost we have to add transportation cost, plant and machinery, plant and machinery is not required here but in rate the analysis we consider transportation, tools and tackles consumables at 5% so we have to add this 5% on material cost = 1050 × 5% = 52.5

So, we have to consider the safety also we have to add 1% amount for safety = 1050 X 1%

= 10.5

Now we have to add material, transportation, tools and tackles, shifting that is

Subtotal = 1050 + 52.5 + 10.5 = 1113/-

Now the labour part, while driving the rate of labour we have to consider the productivity of labour. One Mason can complete 100 square feet area of gypsum plaster in 8 hours.

So labour cost for one Mason = 800 rupees.

One helper = 400/-

here we also, have to take into consideration scaffolding cost for scaffolding. I am considering the rate of 20 rupees per square meter. Since we have considered the rate of 100 square feet of gypsum plaster

So, scaffolding cost = 20 x 100 / 10.764

= 185.87

Now the subtotal = material + labour

= 1113 + 1200+ 185.87

= 2498.87

Now, we have to add 15% for overhead and profit = 2498.87 × 15%

= 374.83

The total rate for 100 square feet of elite-90 gypsum plaster is = 2498.87 + 374.83

= 2873.7 say

= 2874.00

So, per square feet rate for elite -90 gypsum plaster = 28.74 say 29/-

Per square meter rate for elite -90 gypsum plaster = (28.74 × 10.76)

= 309.2 say 309/-

The approximate rate for gypsum plaster on the wall will be around 29/- per square feet.

Hear the rate depends on the labour component. In this rate analysis, I have considered only one mason and one helper for ground level in case of high rise building the labour component may change and the per square feet cost for gypsum plaster can also be changed. So, friends, this was the basic rate analysis for gypsum plaster.
