Key points
- PCC bed assumed 75 mm thick.
- Excavation includes 100 mm working space around the footing.
Formula & how it works
Excavation = L × W × D × count × 1.10 (working space).
PCC = area × 0.075 m; RCC = area × (D − PCC).
Worked example
- 8 isolated footings 5 × 5 × 4 ft.
- Excavation ≈ 25 m³, PCC ≈ 1.4 m³, RCC ≈ 15 m³.
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.
Frequently asked questions
How deep should the footing go?
+
Below the loose top-soil layer, resting on firm strata. Typical residential footings are 3–5 ft deep in this belt — always follow your structural engineer.
