## Cost of Concrete per Cubic Meter

Concrete work in a project usually holds the maximum in terms of overall cost and work quantity. It becomes an important step to calculate the concrete-related costs while preparing a project estimate.

The cost of concrete making depends upon the cost of materials, mix design, workforce, and machinery. You will be looking for what is **Cost of Concrete Work Per Sq Ft **for the construction of a house or building.

In this, we calculate the cost of 1 cubic meter of concrete and other expenses that occur in the preparations of concrete.

## Factors Affecting the Cost of Concrete per Cubic Meter

Following factors which influence cost of concrete work per sq. ft. in construction;

**1. Material Costs**

Costs of materials and supplies and the associated transportation charges affect the cost of any concrete construction project.

**2. Labor Rates**

The local market labor wages or rate per day specified by the state affect the expenditure of a project.

**3. Site Conditions**

The site condition and location of construction affect the cost of the project and concrete. Low and poor soil quality, wetlands, contamination, utility, environmental and traffic issues are few examples in this category.

**4. Schedule**

If the project duration is too short for the type of work and activities involved, then project costs will be on the higher side. This is true for projects with a significant liquidated damage clause in their contracts.

**5. Contingency**

An accidental amount contingency fund of about 10 % of the total expenditure is generally set aside by contractors to cover unforeseen costs. However, market changes and scarcity of materials and supplies might require a higher contingency of the range of 15-20%. contingency added largely affects the cost of concrete work on the construction site.

## How to Estimate Concrete Cost

To calculate **1 cubic meter concrete rate**, Let’s consider the concrete mix of M 20 (1:1.5:3), where, 1 is the part of cement, 1.5 is the part of fine aggregates and 3 is the part of coarse aggregates having a size of 20mm. The water-cement ratio adopted for the mixing concrete is 0.45.

### 1. Assumptions

**Bulk Density:**

- Cement = 1500 kg/m
^{3} - Sand = 1700 kg/m
^{3} - Coarse aggregates = 1650 kg/m
^{3}

### 2. Materials Calculation For 1 m3 Concrete

- Dry volume = Wet Volume X 1.52
- Volume of Cement = (Dry volume X Cement ratio)/ Sum of ratio
**Volume of Cement**= (1 X 1.52)**/**(1+1.5+3)

= 1. 52/5.5- = 0.28m
^{3} - Weight of the cement = 0.28 X 1500
- = 420 kg.
**Volume of Sand**= (1.5 X 1.54)**/**(1+1.5+3)

= 2.31/5.5

= 0.42m^{3}

Weight of the Sand = 0.42 X 1700

= 714 kg.**Volume of Course Aggregate**= (3 X 1.54)**/**(1+1.5+3)

= 4.62/5.5

= 0.84m^{3}- Mass of the Course Aggregate = 0.84 X 1650

= 1386 kg.

### 3. Cost Calculation

- Cost of cement for 1 m
^{3}=

No of Bags = 420/50

=8.4 Bags - As per present market rate, cost of 1 bag of cement is taken as Rs: 330

= 8.4 X 330

= 2772 Rs - Cost of sand for 1 m
^{3 }=

As per present market rate, cost of 1 m^{3}of sand is taken as Rs: 1200

= 0.42 X 1200

= 504 Rs - Cost of course aggregate for 1 m
^{3 }=

As per present market rate, cost of 1m^{3}of course aggregate is taken as Rs.1500

= 0.84 X 1500

= 1260 Rs - Therefore, total cost for 1m
^{3 }of M – 20 concrete is

=Cost of cement + sand + course aggregate

= 2772 + 504 + 1260 = 4536 Rs.**Say Rs 4500 Rs. or 60 Dollars** - Therefore,
**Cost of Concrete Work per sq. ft. is 4500 for 1 m3 of concrete volume**. **Hence, 1m3 concrete is around 4500 Rs. or 60 Dollars****We can Also calculate 1 cft concrete price from 1 m3 concrete price,**- We know that 1 m3 is equal to 35.3147 cft.
- So, 4500/35.3147 = 127.42 Says 128 Rs. per Cft

**Therefore, 1 cft concrete price is 128 Rs. per Cft or 1.70 Dollars Per Cft** **and** **1 cubic meter concrete cost is 4500 Rs. or 60 Dollars**

## Additional Cost of Concrete

The above estimated cost is just for the raw materials of concrete. The complete cost of concreting work also includes the cost of mixing, transporting, compaction equipment, reinforcement, formwork and labour charges

### 1.Mixing

The cost of transportation of materials into the mixer and the mixer charges are added to the concrete.

### 2. Transportation

The properly mixed concrete is to transported to the concreting location with the help of machines and labours. If ready mix concrete is used then its cost is inclusive of transportation cost.

### 3. Compaction

The machinery like vibration use for compaction of Concerte and other tools are also added up to the total cost of concreting.

### 4. Reinforcement

For reinforced concrete work, the cost of steel and labor charges for the cutting and tieing of rebars is also calculated and added to the concrete works.

### 5. FormWork or Shuttering

Concreting work in beam, columns or slab, the formwork required to hold the concrete is also added.

### 6. Skilled Labour

The Labour force required to mix, transport, place, compact and finish the concrete is added to the concreting work cost.

### Q.1 What is labor cost for concrete work?

The **Labour cos**t for concrete work is around 70 to 75 Rs per cft (cubic foot) or 2500 to 2650 Rs per cubic meter (m3). The **Labour Cost **for PCC **concrete** is around **30 to 35 Rs per sq ft** (square foot) or 320 to 400 Rs per cubic meter (m3).

### Q.2 What Is 1 cft concrete price?

The **1 cft concrete price** is** 128 Rs** or **1.70 Dollars **and **1 cubic meter concrete cos**t is **4500 Rs. or 60 Dollars**

### Q.3 How much does it cost to pour a 20 x 20 concrete slab?

**Approximately $2,400.**

To proceed the concrete work of of poring a 20 x 20 concrete slab it will cost around $2,400 or more. Height of the concrete slab is the flexible factor here on which the cost may vary from project to project.

### Q.4 Is concrete work Expensive?

Before understanding the **expensiveness **of concrete it is necessary to talk about its importance in construction. Apart from its cost, it is one of the most important things in construction. Hence being important it has to be given higher **accuracy **which requires **skilled laborers **and hence making it **expensive **in the **working sense**.
