How much material required for 5 Marla house gray structure double story (Roughly Estimation)

To calculate the construction material required for a 5 marla double-story gray structure house, we need to consider the following steps:

1. Calculate the Total Area:

   • 1 marla = 225 sq. ft.
   • 5 marla = 5 * 225 sq. ft. = 1125 sq. ft.

2. Foundation Work:

   • Foundation depth = 3 feet

3. Material Requirements:

Foundation

Assuming an average wall thickness of 1.5 feet (18 inches):

• 
  
• Excavation for Foundation: $$\text{Total length of walls} = \text{Perimeter} \times 2 \text{ (for internal walls)}$$ $$\text{Perimeter} = 4 \times \sqrt{\frac{1125}{4}} \approx 134.16 \text{ ft.}$$ $$\text{Total length of walls} \approx 134.16 \times 2 = 268.32 \text{ ft.}$$ $$\text{Volume of excavation} = \text{Length} \times \text{Width} \times \text{Depth}$$ $$= 268.32 \text{ ft.} \times 1.5 \text{ ft.} \times 3 \text{ ft.} = 1207.44 \text{ cubic feet}$$

Concrete for Foundation

Assuming a 1:2:4 mix for concrete:

• Volume of concrete: $$\text{Volume of concrete} = \text{Volume of excavation} \times \text{Concrete mix ratio}$$ $$\approx 1207.44 \text{ cu. ft.}$$

Superstructure

The superstructure includes walls, slabs, and other components.

1. Bricks:

   • Assuming 9-inch thick walls and standard brick size of 9 x 4.5 x 3 inches
   • Total number of bricks: $$\text{Number of bricks per sq. ft.} = \frac{1}{\text{brick volume in cu. ft.}} \approx 13.5$$ $$\text{Total number of bricks} = \text{Total wall area} \times 13.5$$

2. Cement:

   • Cement for bricks and plastering
   • Typically, 1 bag of cement covers around 100 sq. ft. of brickwork with 1:4 mortar mix.

3. Sand and Aggregate:

   • Sand and aggregate quantities depend on the volume of concrete and plastering work.

4. Steel:

   • Steel requirement for reinforcement typically ranges from 80-120 kg per cubic meter of concrete.

Detailed Calculation

These calculations are high-level estimates. For detailed and accurate material requirements, detailed drawings, and material specifications are needed. Here are rough estimates:

1. Bricks: Approximately 50,000 bricks
2. Cement: 400-450 bags
3. Sand: 1,500-1,800 cubic feet
4. Aggregate: 1,200-1,500 cubic feet
5. Steel: 3.5-4 tons

In these calculated materials, add 3 to 5 % of miscellaneous and multiply the current market rate according to your country area. 

Note

These estimates should be verified with detailed architectural and structural drawings. It is advisable to consult with a professional civil engineer or contractor to get precise measurements and material requirements.
