Key points
- Steel assumed 2.5% of column volume — heavy sections may go higher.
- M20 concrete by default.
Formula & how it works
Column volume = W × D × H × N (metres).
Steel = volume × 2.5% × 7850.
Worked example
- 8 columns 9" × 12" × 10 ft → ≈ 1.7 m³ concrete, ≈ 335 kg steel.
Expert tips & mistakes to avoid
- Always add a 5–7% wastage buffer — mid-slab shortages cost more than the buffer bags.
- For engineered members (RCC columns/beams), follow the structural drawing over any calculator.
- Order cement in tranches — bags older than 90 days lose strength.
- Confirm the current market rate on WhatsApp before finalising the budget — prices printed here are indicative only.
