Q: How does the AI calculate material quantities?

The AI uses IS code-compliant mix design formulas (IS 456 for concrete, IS 2212 for brickwork) calibrated against Buildogram's database of completed Chennai projects. For concrete items, it uses M20/M25 mix designs with standard water-cement ratios. For masonry, it applies standard fly-ash brick sizes (230×115×75mm) with mortar wastage factors.

Q: Are these procurement quantities or BOQ quantities?

These are procurement quantities — inclusive of standard wastage factors: 5–10% for cement, 3–5% for steel, 8–12% for bricks, and 10% for tiles. Always useful for planning material orders before approaching suppliers.

Q: Can I use this to plan material purchases from vendors?

Yes. After getting your estimate, you can request sourcing support for cement, steel, and other items. Current quotations and supplier documentation can be requested where applicable.

Q: Does it account for different IS grades of concrete and steel?

Yes. Select M20 or M25 concrete grade and Fe415/Fe500D steel grade to get grade-appropriate quantity estimates. For higher grade concrete (M30+) used in commercial buildings, our engineers can provide custom estimates.

Q: How accurate are these estimates?

Typical accuracy is ±10–15% for standard residential builds in Chennai. Accuracy improves when you provide exact floor areas, specification level, and foundation type. For procurement planning, always allow a 10% buffer above the estimate.
