Introduction to quantit of measure work


 🏗️ INTRODUCTION TO QUANTITY OF MEASURED WORK

Today I bring a short but very basic lesson for craftsmen, managers and homeowners.

In any construction work, it is very important to know the exact amount of materials needed before starting work.

This helps:

✅ Avoid waste of materials

✅ Budget accurately

✅ Control the quality of work

✅ Avoid unnecessary losses

To achieve this, it is necessary to understand the basics of construction materials, especially concrete mixtures.

🧱 CONCRETE STRENGTH

The strength of concrete depends on the ratio of the mixture of cement, sand and gravel (aggregates) as well as the amount of water used.

These are the grades of concrete that are most often used:

1️⃣ Concrete Grade 30

Ratio: 1 : 1 : 2

Water: 25 Liters

👉 Used in columns and areas that carry heavy loads. 

2️⃣ Concrete Grade 25

Ratio: 1 : 1.5 : 3

Water: 27 Liters

👉 Suitable for regular columns and beams.

3️⃣ Concrete Grade 20

Ratio: 1 : 2 : 4

Water: 30 Liters

👉 Widely used in slabs and floors.

4️⃣ Concrete Grade 15

Ratio: 1 : 3 : 6

Water: 34 Liters

👉 Suitable for light-duty applications.

5️⃣ Concrete Grade 10

Ratio: 1 : 4 : 8

👉 Used for blinding or low-load applications.

6️⃣ Concrete Grade 7.5

Ratio: 1 : 5 : 10

7️⃣ Concrete Grade 5

Ratio: 1 : 6 : 12

⚠️ NOTE

• Do not add too much water – it reduces the strength of the concrete.

• Ensure that the measurements are followed correctly.

 • Use clean materials that are free of dirt or debris.

📌 Good construction starts with the right knowledge.

If you understand the measurements, you will save money and get a strong and safe home.

 🏢 Lesson: Building an Apartment in a High-Cost Area (Urban) Many people who buy a small plot in a high-cost city make one very big mistake: They build a bungalow and reduce the real value of their plot. ❗ Very Important Fact If your plot: Is small in size Is located in a commercial area or in the center of the city The price of the plot is higher than the cost of building a small house 👉 The right solution is not a bungalow — it's an Apartment. 🎯 Reasons to Build an Apartment in a High-Cost Area 1️⃣ Better use of land Instead of using the entire 120 meters below, you build 60 meters below + 60 meters above. You use the land wisely, not by habit. 2️⃣ The value of the building increases more than the plot An apartment increases the value of the property two to three times compared to a small house.  3️⃣ Income Property Bottom: Business / Office / Rental Frames Top: Residential or rental apartments The building starts to generate money for you. 4️⃣ The foundation and roof are...
