👉Site Engineer Quick Calculation Guide you uploaded, with details for each formula:

📐 Concrete Quantity

- Formula: 0.036 × Built-up Area (m²)
- Purpose: Quick estimation of concrete required based on total built-up area. Useful for preliminary planning.

🪚 Shuttering Quantity

- Formula 1: Concrete Quantity × 6
- Formula 2: 2.4 to 2.5 × Slab Area (m²) (includes column, beam & slab sides)
- Purpose: Helps calculate shuttering material needed for formwork.

🪵 Number of Plywood Sheets

- Formula: Shuttering Quantity × 0.22
- Purpose: Approximate count of plywood sheets required for shuttering.

🪵 Number of Battens

- Formula: Number of Plywood Sheets × 19.62
- Purpose: Estimate of battens needed to support plywood sheets.

🔩 Nails

- Formula: 0.075 × Shuttering Quantity (m²)
- Purpose: Quick calculation of nails required for fixing shuttering.

🧵 Binding Wire

- Formula: 0.075 × Shuttering Quantity (m²)
- Purpose: Used for tying reinforcement bars during concreting.

🛢️ Formwork Oil

- Formula 1: 0.065 × Shuttering Quantity (m²)
- Formula 2: 1 Litre for 15 m² (application rate)
- Purpose: Prevents concrete from sticking to shuttering, ensuring smooth removal.

🔗 Steel (Bars)

- First & Third Floor Slab: 4.425 Kg / Sq.ft
- Above Third Floor Slab: 6.625 Kg / Sq.ft
- Purpose: Quick thumb rule for reinforcement steel consumption depending on floor level.

✅ This guide is designed for site engineers to make fast, practical estimates without lengthy calculations. It’s best used for preliminary planning and quick checks before detailed BOQ preparation.
