Brickwork is one of the most essential and commonly executed activities on any construction site. Whether it’s for walls, partitions, or boundary walls, understanding how to estimate brickwork and carry out a rate analysis is crucial for civil engineers, contractors, and quantity surveyors.
In this blog, we’ll explain:
- What is brickwork estimation?
- What factors are included in brickwork rate analysis?
- Step-by-step rate analysis of brickwork with an example
- Common mistakes to avoid
What is Brickwork Estimation?
Brickwork estimation refers to the process of calculating the number of bricks, quantity of mortar, and cost of materials and labour required for brick masonry. Brickwork is measured in cubic meters (m³) for volume and square meters (m²) for surface finish (like plastering).
Estimating brickwork involves:
- Calculating the volume of brick masonry
- Deducting openings (doors, windows, etc.)
- Estimating materials: bricks, cement, sand
- Calculating labour and overhead charges
Rate Analysis of Brickwork – What’s Included?
To analyse the rate of brickwork per 1 m³, we need to consider:
| Component | Description |
| Bricks | Number and cost per 1 m³ |
| Cement | Bags of cement used in mortar |
| Sand | Volume of sand used in mortar |
| Water | For mortar mixing |
| Labor Charges | Mason, helper, supervisor |
| Sundries | Tools, curing, wastage, etc. |
| Contractor’s Profit | Typically, 10-15% |
Steps in Estimating Brickwork
Quantity of Bricks
Standard size of brick = 190 mm × 90 mm × 90 mm
Including mortar = 200 mm × 100 mm × 100 mm = 0.002 m³
Number of bricks in 1 m³
= 1 / 0.002
= 500 bricks
Add 5% wastage = 500 × 1.05 = 525 bricks
Mortar Quantity
- Volume of 1 m³ brickwork = 1 m³
- Volume of bricks = 500 × 0.19 × 0.09 × 0.09 = 0.77 m³
- Volume of mortar = 1 – 0.77 = 0.23 m³
Dry volume of mortar = 0.23 × 1.33 = 0.3059 m³
Mix ratio = 1:6
Total = 1 + 6 = 7
- Cement = (1/7) × 0.3059 = 0.0437 m³
0.0437 × 1440 = 62.9 Kg ( Unit weight of cement is 1440 )
62.9 Kg / 50 kg = 1.258 ≈ 1.5 Bag
- Sand = (6/7) × 0.3325 = 0.285 m³
Material Cost (as per market rates)
| Item | Qty | Rate (INR) | Amount (INR) |
| Bricks | 525 Nos | ₹8/brick | ₹4,200 |
| Cement | 1.5 Bags | ₹450/bag | ₹675 |
| Sand | 0.285 m³ | ₹1,000/m³ | ₹285 |
| Water | Lumpsum | ₹20 | |
| Total | ₹5,180 |
Labor Cost
| Labor Type | Nos | Rate (INR) | Amount (INR) |
| Mason | 1 | ₹1200/day | ₹1200 |
| Helper | 1 | ₹800/day | ₹800 |
| Total | ₹2,000 |
Add Sundries, Overheads, Profit
- Sundries & tools = ₹50
- Contractor Profit (10%) = ₹605
Final Rate Analysis Summary
| Component | Cost (INR) |
| Material Cost | ₹5,180 |
| Labor Cost | ₹2,000 |
| Sundries | ₹50 |
| Contractor Profit (10%) | ₹718 |
| Total Rate / m³ | ₹7,948 |
So, the rate of brickwork in 1:6 cement mortar per m³ = ₹7,948 approx
Real-Site Example
Suppose you have a wall of size 10 m length × 3 m height × 0.23 m thickness.
Volume of brickwork = 10 × 3 × 0.23 = 6.9 m³
Total brickwork cost = 6.9 × ₹7950 = ₹54,855
Pro Tips for Brickwork Estimation
- Always account for 5–10% wastage in bricks and mortar.
- For plastered surfaces, brick joints can be thicker; therefore, adjust the mortar volume accordingly.
- Use local material rates for accurate estimation.
- Use rate analysis software or Excel sheets for bulk estimation.
Key Takeaways
- Standard 1 m³ brickwork requires ~525 bricks, 1.5 bags of cement, and 0.30 m³ of sand.
- Always add wastage and the contractor’s profit while preparing estimates.
- Labour cost varies depending on region and project size.
- For accuracy, update material rates as per local market prices.

The above brickwork rate analysis is provided for educational and reference purposes only. The material and labour rates used in this calculation are approximate and may vary based on location, market fluctuations, quality of materials, labour availability, and site conditions. Always consult with local contractors, suppliers, or engineers for accurate and up-to-date costing before executing any construction work.
Conclusion
Estimating brickwork with proper rate analysis ensures accurate budgeting and effective cost control during construction. With a standard formula and real-time rates, even site engineers and junior quantity surveyors can quickly arrive at reliable estimates.
