Assumptions

• Base rate ₹1800/sqft (national indicative) for Bengaluru.
• Quality multiplier ×1 (standard) maps to STANDARD specifications for detailed BOQ — the ₹/sq ft total remains a quick estimate.
• Floor multiplier ×1.04 for 2 floor(s).
• Location multiplier ×1.12.
• Cost split material 52% / labour 32% / misc 16%.
• Market rates in model: steel ₹55/kg, cement ₹380/bag, labour index 100.
• Contingency 10% on subtotal.
• Category and phase shares are planning allocations, not contractor bills.
• Always verify rates with local contractors and suppliers before budgeting.
• Verify locally with suppliers or contractors before budgeting. These are not live market prices.

Methodology

total ≈ (area_sqft × cost_per_sqft + features) × (1 + contingency%)

1. Start from base location rate (₹1800/sqft) for Bengaluru.
2. Apply quality multiplier (standard: ×1) and attach STANDARD specification mapping (not a substitute for a detailed BOQ).
3. Apply floor multiplier (×1.04).
4. Foundation type left at default (×1.0).
5. Structure type left at default (×1.0).
6. Add optional features (0 item(s), ₹0).
7. Split into material / labour / miscellaneous using configured percentages.
8. Adjust for steel / cement / labour rate overrides vs market defaults when provided.
9. Add contingency (10%).
10. Publish a likely range of ±12% around the mid estimate.
