Rate Analysis for Brickwork — Cost per Sq Ft for 4.5 and 9 Inch Walls

Introduction

Brickwork is the single largest masonry item in most Indian construction projects. Whether you are building a house, apartment, or commercial space, getting the rate analysis for brickwork right determines whether you make a profit or a loss on the job.

This guide breaks down the complete rate analysis — bricks, cement, sand, labour, and overheads — for both 4.5-inch and 9-inch walls. We give you cost per square foot (the way contractors think on Indian sites) and per cubic metre (the way it appears in tenders and BOQs). We also compare brick walls with AAC blocks so you can advise your clients on the better option.

Brickwork Basics

Standard Brick Sizes in India

Brick Type	Size (mm)	Weight	Cost (2026)
Standard modular (IS 1077)	190 x 90 x 90	2.8-3.2 kg	Rs 8-12
Fly ash brick	230 x 110 x 75	2.5-3.0 kg	Rs 6-8
Country/desi brick	230 x 115 x 75	3.0-3.5 kg	Rs 5-8
AAC block (for comparison)	600 x 200 x 100	8-10 kg	Rs 45-60

All calculations below use standard modular bricks (190 x 90 x 90 mm) with 10mm mortar joints unless stated otherwise.

Wall Thickness Options

Wall Type	Nominal Thickness	Actual Thickness	Use
Half brick wall	4.5 inch	100 mm (90 + 10 mortar)	Partition walls, non-load-bearing
Full brick wall	9 inch	200 mm (190 + 10 mortar)	External walls, load-bearing
One-and-half brick	13.5 inch	300 mm	Heavy load-bearing, retaining

Rate Analysis: 9-Inch Brick Wall (Per Cubic Metre)

Let us start with the standard rate analysis for 1 cubic metre of brickwork in 1:6 cement mortar.

Step 1: Brick Quantity

• Brick size with mortar = 200 x 100 x 100 mm (adding 10mm joint to each face)
• Volume of one brick with mortar = 0.20 x 0.10 x 0.10 = 0.002 cum
• Bricks per cum = 1 / 0.002 = 500 bricks
• Add 5% wastage = 500 x 1.05 = 525 bricks

Step 2: Mortar Quantity

• Actual brick volume = 500 x (0.19 x 0.09 x 0.09) = 0.7695 cum
• Wet mortar volume = 1.0 - 0.7695 = 0.2305 cum
• Dry mortar volume = 0.2305 x 1.33 = 0.3066 cum

For 1:6 ratio (total 7 parts):

• Cement = (1/7) x 0.3066 = 0.0438 cum = 0.0438/0.0347 = 1.26 bags
• Sand = (6/7) x 0.3066 = 0.263 cum

Add 5% wastage:

• Cement = 1.26 x 1.05 = 1.33 bags
• Sand = 0.263 x 1.10 = 0.289 cum

Step 3: Material Cost

Material	Quantity	Rate	Cost
Bricks (first class)	525 nos.	Rs 10/piece	Rs 5,250
Cement	1.33 bags	Rs 400/bag	Rs 532
Sand	0.289 cum	Rs 2,400/cum	Rs 694
Water	75 litres	Rs 1/litre	Rs 75
Material total			Rs 6,551

Step 4: Labour Cost

Labour	Rate per Cum
Mason (1st class)	Rs 600-900
Helper/mazdoor (2 nos.)	Rs 400-600
Labour total	Rs 1,000-1,500

We take Rs 1,200 per cum as the average for metro cities.

Step 5: Sundry Charges

Item	Rate per Cum
Scaffolding	Rs 100-200
Tools and tackles	Rs 50-80
Curing (water + labour)	Rs 50-100
Wastage contingency	Rs 100
Sundry total	Rs 300-480

We take Rs 380 per cum.

Step 6: Total Rate per Cubic Metre

Component	Cost per Cum
Materials	Rs 6,551
Labour	Rs 1,200
Sundries	Rs 380
Sub-total	Rs 8,131
Contractor overhead + profit (12%)	Rs 976
Grand total	Rs 9,107 per cum

Converting to Cost per Square Foot

Now let us convert the per-cum rate to per sq ft — the unit most contractors and homeowners understand.

9-Inch Wall (Full Brick)

• Thickness = 0.20 m (actual)
• Volume per sq m of wall = 1 x 0.20 = 0.20 cum
• Volume per sq ft of wall = 0.20 / 10.764 = 0.01858 cum

Cost per sq ft = 0.01858 x Rs 9,107 = Rs 169 per sq ft

Wait — that seems high. Let me break it down more practically. Many contractors quote brickwork rate per sq ft which includes only material and labour (excluding contractor profit):

Practical rate per sq ft (9-inch wall):

• Material + Labour + Sundry = Rs 8,131 per cum
• Per sq ft = 0.01858 x 8,131 = Rs 151 per sq ft

But hold on — in site practice, the effective rate varies. Here is a realistic range:

City	9-Inch Wall (per sq ft)	Including material + labour
Mumbai	Rs 90-110	Higher brick and labour cost
Delhi	Rs 80-100	Moderate rates
Bangalore	Rs 85-105	Higher labour, moderate material
Pune	Rs 75-95	Slightly lower than Mumbai
Tier-2 cities	Rs 65-85	Lower labour and material cost

Note: The theoretical rate analysis gives Rs 150+ per sq ft, but market rates are lower because contractors negotiate bulk brick prices, use slightly leaner mortar, and have optimised labour productivity. The rate analysis serves as a ceiling — your actual tendered rate will typically be 60-75% of the theoretical analysis.

4.5-Inch Wall (Half Brick)

• Thickness = 0.10 m (actual)
• Volume per sq ft = 0.10 / 10.764 = 0.00929 cum

Cost per sq ft = 0.00929 x Rs 8,131 = Rs 75.54

Practical market rates for 4.5-inch walls:

City	4.5-Inch Wall (per sq ft)
Mumbai	Rs 50-65
Delhi	Rs 42-55
Bangalore	Rs 45-60
Pune	Rs 40-52
Tier-2 cities	Rs 35-45

The 4.5-inch wall costs roughly 55-60% of the 9-inch wall per sq ft (not 50%, because labour per sq ft is nearly the same — the mason has to lay the same number of courses).

Quick Reference: Materials per 100 Sq Ft of Wall

Item	4.5-Inch Wall	9-Inch Wall
Bricks	560 nos.	1,125 nos.
Cement (1:6)	1.5 bags	3 bags
Sand	0.31 cum	0.62 cum
Labour (mason days)	0.5 days	1 day
Labour (helper days)	1 day	2 days

These figures are approximate and include standard wastage allowances.

AAC Block vs Brick: Cost Comparison

Many clients now ask about AAC (Autoclaved Aerated Concrete) blocks. Here is a head-to-head comparison for a 100 sq ft wall:

4-Inch AAC Block Wall vs 4.5-Inch Brick Wall

Parameter	Red Brick (4.5")	AAC Block (4")
Units needed	560 bricks	56 blocks
Unit cost	Rs 10/brick = Rs 5,600	Rs 55/block = Rs 3,080
Cement	1.5 bags = Rs 600	10 kg adhesive = Rs 300
Sand	0.31 cum = Rs 744	Not needed (adhesive)
Labour	Rs 800-1,000	Rs 500-700
Material + Labour	Rs 7,744-7,944	Rs 3,880-4,080
Plastering (both sides)	Rs 2,000	Rs 1,200 (thinner plaster)
Total per 100 sq ft	Rs 9,744-9,944	Rs 5,080-5,280
Rate per sq ft	Rs 97-99	Rs 51-53

Key findings:

• AAC blocks are 45-48% cheaper per sq ft when you include plaster savings
• AAC is faster to lay (larger blocks, thin-bed adhesive)
• AAC provides better thermal insulation (lower AC costs)
• However, AAC is weaker in holding heavy fixtures — use special anchors for wall-mounted items

6-Inch AAC Block Wall vs 9-Inch Brick Wall

Parameter	Red Brick (9")	AAC Block (6")
Rate per sq ft (all-inclusive)	Rs 90-110	Rs 65-80
Weight per sq m	400-450 kg	100-130 kg
Construction speed	8-10 sq m/day	15-20 sq m/day

AAC walls are significantly lighter, which can reduce structural steel and foundation costs in multi-storey buildings. Many builders in Bangalore, Pune, and Mumbai have switched to AAC for interior walls while keeping brick for external walls.

Rate Analysis Variations by Brick Type

Fly Ash Brick Wall

Parameter	Per Cum	Difference vs Red Brick
Bricks (460 nos. at Rs 7)	Rs 3,220	-Rs 2,030 (fewer bricks, lower rate)
Cement (1.1 bags)	Rs 440	-Rs 92 (better brick uniformity)
Sand	Rs 650	-Rs 44
Labour	Rs 1,100	-Rs 100 (easier to lay)
Total per cum	Rs 5,410	33% cheaper

Fly ash bricks are a strong alternative for cost-conscious projects. They are lighter, more uniform, and consume less mortar. The main drawback is lower compressive strength compared to first-class red bricks.

Country/Desi Brick Wall

Country bricks are irregular in shape and size, which means:

• More mortar consumption (up to 35-40% of wall volume vs 23% for modular bricks)
• Slower laying speed (more cutting and fitting)
• Thicker plaster needed to achieve a flat surface

Despite the lower brick cost (Rs 5-8), country brick walls often end up costing only 5-10% less than modular brick walls when you account for higher mortar and plaster consumption.

Cost Breakdown by Percentage

Understanding the cost split helps you identify where to save:

Component	9-Inch Wall	4.5-Inch Wall
Bricks	64%	62%
Cement	7%	7%
Sand	9%	9%
Labour	15%	16%
Sundries	5%	6%

Bricks are the dominant cost (62-64%). Negotiating a better brick rate has the highest impact on total cost. A Rs 1 per brick discount on a 9-inch wall saves Rs 525 per cum or about Rs 10 per sq ft.

Practical Tips for Contractors

1. Negotiate Brick Rates in Bulk

Buy bricks in lots of 5,000-10,000 or more. Suppliers typically offer Rs 0.50-1.00 per brick discount for bulk orders. On a house project using 20,000+ bricks, that saves Rs 10,000-20,000.

2. Minimize Brick Wastage

Train masons to handle bricks carefully. Breakage on site can reach 8-10% with careless handling vs 3-5% with proper stacking and handling. That is a Rs 2,000-5,000 difference per 10,000 bricks.

3. Check Brick Quality Before Buying

Test a sample: good bricks produce a clear ringing sound when struck together, have sharp edges, uniform colour, and water absorption below 15%. Poor quality bricks lead to cracking, efflorescence, and rework costs.

4. Use the Right Mortar Ratio

Do not use 1:4 mortar for internal partition walls — it wastes cement. And do not use 1:8 for structural walls — it compromises safety. Match the ratio to the wall function.
