Brickwork is one of the largest BOQ items by volume + cost on most Indian buildings — typically 15-25% of construction cost for residential / commercial. 1st class brickwork uses high-quality clay bricks (IS 1077) in cement-sand mortar — the standard for visible / load-bearing / external walls.
The Rate Analysis builds up the per-m³ rate from materials (bricks, cement, sand) + labour + scaffolding + ancillaries. Used for tender pricing, claim defense, variation order rates.
For brick 230 × 110 × 75 mm + 12 mm mortar joints:
Bricks: 500 bricks/m³ (with 5% wastage = 525) - 1st class brick price: ₹5-10/brick depending on region - Bricks cost: ₹2,625-5,250/m³
Mortar (CM 1:6 cement-sand) — ~25% of volume = 0.25 m³: - Cement: 0.25 × 280 kg/m³ = 70 kg = 1.4 bags @ ₹400-450 = ₹560-630 - Sand: 0.25 × 1.5 (dry/wet bulking) = 0.375 m³ @ ₹1,500-2,500/m³ = ₹565-940 - Mortar cost: ₹1,125-1,570/m³
Labour: - Mason: 0.5-0.7 day @ ₹650-900/day = ₹325-630 - Helper: 0.7-1.0 day @ ₹450-650/day = ₹315-650 - Labour cost: ₹640-1,280/m³
Other: - Scaffolding (for above ground floor): ₹100-300/m³ - Curing labour + water: ₹50-100/m³ - Wastage (already in bricks above): nil - Overhead (10-15%): ₹500-1,000 - Profit (10-15%): ₹500-1,000
Total: ₹5,540-10,500/m³
Note: Variations are significant by region. Bangalore + Mumbai pricing ~30% premium over tier-2 cities.
1. Wrong brick count — varies with brick size. Modular brick (190 × 90 × 90) = 600/m³; conventional (230 × 110 × 75) = 500/m³. 2. Mortar ratio confusion — CM 1:6 vs 1:4 mortar significantly different cement cost. Specify mix in rate analysis. 3. Sand quality assumed — river sand vs M-sand price differs significantly; assume correct source. 4. Wastage too low — site wastage on bricks typically 8-12% (theft + breakage); 5% is optimistic. 5. No scaffolding — external brickwork needs scaffolding; often forgotten in rate analysis. 6. Curing labour missed — 7-14 days curing requires daily water spraying; small but real cost. 7. Productivity unrealistic — assuming 1 mason can build 3-4 m³/day; actual 2.5 m³ in normal conditions, less at height. 8. Material reconciliation gaps — brick consumption per m² differs by orientation (flat vs vertical); rate analysis should use consistent assumptions.
