Today we are going to discuss the rate analysis of concrete along with an example calculation for M25 Concrete. Before that, you must understand the steps involved in **rate analysis**. We have already discussed the rate analysis basics.

**How to do rate analysis for concrete?**

To get almost nearby accurate rate analysis, you have to consider the following things,

- Material Estimation
- Labour Estimation
- Power consumption
- Water consumption
- Tools and equipment
- Contingencies
- Overhead & Profit

**1. Estimation of Materials**

Assume We need 1 m3 of wet volume concrete of M25 Mix, (Mix Ratio, M25 = 1: 1 : 2)

So **Total Parts = 1+1+2 = 4 Parts** which gives Dry volume that means before adding water content

Volume of concrete = (1 Cement Part)/4 + (1 Sand Part)/4 + (2 Coarse Aggregate Part)/4

Therefore,

- Volume of Cement = 1/4 x 1.55
- Volume of Sand = 1/4 x 1.55
- Volume of Coarse Aggregate = 2/4 x 1.55
- From the IS Code standard, Assuming the water-cement ratio for M20 is 0.5

The reason for that 1.55 has been already discussed in theconcrete ingredients calculationtopic.

So the required

- Cement Volume –
**0.3875 m3 or 11.16 Bags** - Sand Volume –
**0.3875 m3** - Coarse Aggregate –
**0.775 m3** - Required Water –
**193.75 Litres**

We have estimated the material requirement.

**2. Labour Estimation**

As per our Labour Output Thumb Rule estimation. We assume that we need approx manpower in terms of days as below

- Foreman – 0.05
- Mason – 0.3 Day
- Male Coolie – 1 Day
- Female Coolie – 1 Day
- Waterman – 0.1 Day

We had covered the crucial task and we shall add a certain percentage for water, power consumption, etc.,

**How do you calculate the rate analysis of m25 grade concrete? **
