Column Master Estimator – Concrete, Steel & Formwork
Quality Inspector
Comprehensive estimator for structural columns. Perfect for site engineers preparing material indents.
📐 Formula & Method
Concrete volume = L×W×H×Qty. Steel weight uses standard density of 7850 kg/m³. Shuttering covers the perimeter of all columns.
Shuttering = Perimeter × Height × Qty
📋 Worked Example
9"x12" column, 10ft high: • Concrete ≈ 0.2 m³ • Steel (2%): 31 kg • Shuttering: 6.5 m²
