How to calculate the cost of MS window grill?/ Estimation & rate analysis of MS window grill.

 Let us calculate the cost of the MS window grill as shown below.

Given data:

Length of MS grill  = 790mm.

Width of MS grill  = 660mm.

MS grill frame material  👉  MS flat of 30 × 5mm. size.

 MS grill mesh material  👉    MS square bar of 12mm. size.

Holdfast is made of an MS square bar  👉  120mm in length.

 The crossbar of holdfast  👉    2nos., each of  50mm. length 

A. Material cost:

❤ How to estimate the material for the MS grill of a window?

Note:

a. The length of the material (below) is taken from the above-linked article. 

b. The weight of the material (below) is taken from the wt. table chart.

 1.  The required length of MS flat = 2.90m.

      The weight of the MS flat of 30 × 5mm. size. = 1.18kg./m.

 2. The required length of the MS square bar for grill mesh          = 8.7m.

 3. The required length of the MS square bar for a single holdfast = 0.22m

   The total length of the MS square bar

     = [length of MS sq. bar for mesh + ( 4nos. × sq. bar length for holdfast)]

      = [ 8.7m. + ( 4nos.× 0.22m.)]

      = 9.58m.

   The weight of the MS square bar of 12mm. size. = 1.10kg./m.

Let us calculate the total material cost in table format.

Sl. no.	Item.	Length in m.	Weight Kg /m.	Total Wt. in kg	Rate/kg in INR	Total Cost  in INR
1.	MS flat	2.90	1.18	3.42	55/-	188.10
2.	MS square bar	9.58	1.10	10.54	53/-	558.62
3.	The material cost =					746.72
4.	Add transport charges (lump sum) =					100.00
5.	Add 5% wastage =					37.34
6.	Total material cost =					884.06

 

Note: Insert the ongoing market rate of materials in your country to get the correct result.

👀.  Area of the window grill

      = [length × breadth]

      = [ 790mm. × 660mm.]

      = [ 0.79m. × 0.66m.]

      = 0.5214 sq m.

 👀.  Total wt. of the material

       = [wt. of MS square bar + wt. of MS flat]

       = [ 10.54kg. +3.42 kg.]

       = 13.96kg

B. Labor cost:

   a. Labor rate on a weight basis:

  The labor rate of the window grill is between INR 35/- to INR 45/- per kg.

  Let us consider an average rate of INR 40/- per kg.

The labor cost

= [wt. of the material × labor rate/kg.]

= [ 13.96kg. × 40/- ]

= INR 558/-

 b. Labor rate on an area basis:

 The labor rate of the window grill is between INR 800/- to INR 1300/- per sq m.

 Let us consider an average rate of INR 1050/- per sq m.

  The labor cost

   = [area of window grill × labor rate/sq m.]

   = [ 0.5214 × 1050/- ]

   = INR 548/-

Note: The labor rate mentioned above is inclusive of welding rods.

👀. The total cost of MS window grill

       = [ material cost + labor cost ]

      = [ INR 884.06/- + INR 548/- ]

         =  INR 1432/-

👀. The cost of MS window grill / sq m.

      = [ total cost ÷ grill area in sq m.]

      = [ 1432/- ÷ 0.5214 ]

      = INR 2746/-

👀. The cost of MS window grill/ sq ft. 

      = [ grill cost /sq m. ÷ 10.764 ]

       ( As 1 sq m. = 10.764 sq ft.)

       = [ 2746/- ÷ 10.764 ]

        = INR 255/-

      

Note:

1. The cost of the window grill depends upon the window size, volume of work, material rate, & labor rate in the particular region.

2. The purpose of this article is to show the calculation procedure of window grill cost. In no way, you can consider the above-calculated cost as the actual MS grill rate.
