**Rate Analysis For Concrete**

**Rate Analysis** – It is a summary of all the cost involved in doing particular work or unit work. For rate analysis, the details about all the operation involved in carrying out the work should be available.

The quantities of materials required and their cost should be known and the number of different categories of labours required and the capacity of doing work per labour and their wages per day should be known. These can be known only from the experience of particular work.

For calculating the rate per unit of an item following sub-heads are estimated and added together to get the rate per unit of an item.

1. Quantity of material and Its cost

2. Labour cost

3. Cost of equipment or Tools and plants( 1.5%)

4. Water charges (1.5%)

5. Overhead expenses (2 to 5%)

6. Contractor profit (10%)

**Rate Analysis for 1 cum of M15(1:2:4)**

**Quantity of material and its cost**

Cement = 1.54/7 = 0.22 cum × 28.8 = 6.336 bags

Sand = 0.22 × 2 = 0.44 cum

Aggregate = 0.22 × 4 = 0.88 cum

Cement = 6.336 bags @ 300/- = 1900.8

Sand = 0.44 cum @ 1000 per cum (crushed sand) = 440/-

Aggregate = 0.88 cum @ 800 per cum = 704/-

Total Material cost is = 1900.8 + 440 + 704 = 3044.8

**Labour Cost**

0.3 mason and 2 labours for one day are required for carrying out 1 Cum concrete.

Mason @ 600 per day = 0.3 × 600 = 180

Labours @ 300 per day = 2 × 300 = 600

Total Amount of labour = 780/-

Subtotal = 3044.8 + 780 = 3824.8

Add 1.5% water charges on subtotal amount = 3824.8 × 1.5% = 57.372

Add Sundries 3% (Including mixture machine, transportation, tools etc) = 3824.8 × 3%

= 114.74

Add 15% for Overhead and Contractor Profit on subtotal amount = 3824.8 × 15%

= 573.72

Total = 3824.8 + 57.372 + 114.74 +573.72

Total = 4570.632 say 4570.00

So, Rate for 1 cum of **M-15** concrete is = **4570.00**
