Standards & Verification Methodology
All construction and material quantity calculators conform to Indian Standards (Bureau of Indian Standards - BIS) and international building estimation manuals:
- Concrete Mix Design: Strict adherence to IS 456:2000 (Plain and Reinforced Concrete - Code of Practice) with standard 1.54 dry volume coefficient and 1,440 kg/m³ cement bulk density.
- Brickwork & Masonry: Compliance with IS 1077 for common burnt clay bricks, incorporating nominal 10 mm mortar joint thickness and standard volumetric batching.
- Finishing & Wastage: Real-world wastage factors (5–10% for concrete and brickwork, 10% for ceramic/vitrified tile cutting) to prevent on-site material deficits.
