The ConstrCalc materials tab pre-populates typical residential quantities per 1,000 ft². These are conservative South-Asian RCC (Reinforced Cement Concrete) residential norms. For North-American wood-frame, Australian brick-veneer, or European steel-frame construction, override the quantities with your regional standards or use Manual Entry.
Standard Quantities per 1,000 ft²
| Material | Reference Quantity | Unit |
|---|---|---|
| Cement | 400 | Bags |
| Sand | 81.6 | Ton |
| Steel / Rebar | 4,000 | Kg |
| Bricks | 8,000 | Pieces |
| Aggregate | 1,350 | ft³ |
| Paint (2 coats) | 2.5 | Gallons |
Regional Adjustments
Every construction market is different. Adjust in one of two ways:
- Change total area proportionally. If your local cement norm is 300 bags per 1,000 ft², enter 750 ft² for a 1,000 ft² job. Quick but coarse.
- Use Manual Entry to bypass standard quantities entirely. Enter your own material name, quantity, unit, and unit price. Precise.
Standards are for speed. Manual entry is for accuracy. ConstrCalc never claims either is “correct” — you decide.
