Estimation And Rate Analysis of Rubble Soling Work
Let us now calculate the cost of Rubble soling as shown in the below drawing.
Given data:
Length of the rubble soling = 15 ft.
Width of the rubble soling = 8 ft.
The thickness of the rubble soling = 0.75 ft.
The total volume of the rubble soling
= [length × width × thickness]
= [15 ft. × 8 ft. × 0.75 ft.]
= 90 cu ft.

So that you will understand the calculation concept clearly, without any questions.
- Material calculation:
- Volume of rubble stone:
The required volume of stone
= [1.25 × the vol. of rubble soling]
= [1.25 × 90 cu ft.]
= 112.50 cu ft.
- Volume of moo-rum:
The required vol. of moo-rum
= 15% of the vol. of rubble stone.
= [15 × 112.5 cu ft. ÷ 100]
= 16.875 cu ft.
- Labor calculation:
The labor rate per cu ft. of the rubble soling work ranges from INR 9/- to 15/- depending upon the region.
Let us consider an average rate of INR 12/– per cu ft.
The total cost of labor for rubble soling
= total vol. of rubble soling in cu ft. × labor rate/ cu ft.
= 90 cu ft. × 12/-
= INR 1,080/-

Now, let us calculate the total cost of rubble soling in table format.
Sl. no. | Item. | Qty. | Rate.
in INR. |
Unit. | Cost
in INR. |
1. | Rubble stone | 112.50 | 33/- | Cu ft. | 3,712.50 |
2. | Moorum | 16.88 | 12/- | Cu ft. | 202.56 |
3. | Rent of compactor | Lump-sum | 200.00 | ||
4. | Water for flooding | Lump-sum | 100.00 | ||
5. | Miscellaneous | Lump-sum | 100.00 | ||
6. | The material cost = | 4,315.06 | |||
7. | Add 5% wastage = | 215.75 | |||
8. | Total material cost = | 4,530.81 | |||
9. | Labour cost = | 1,080.00 | |||
10. | The total cost of rubble soling work = | 5610.81 |
Note: To get accurate results, insert your regional market rate of materials and labor, in the above table.
- The cost of rubble soling /cu ft.
= [total rubble soling cost ÷ total soling vol. in cu ft.]
= [5,610.81 ÷ 90]
= INR 62.34 /cu ft.

- The cost of rubble soling /cum.
= [62.34 × 35.3147]
= INR 2,201.60 / cum.
( As 1cum = 35.3147 cu ft.)
Note:
If the work is handed over to any contractor, you have to add 10% extra for his profit.
