Shortcuts Construction Materials Quantity Estimation Formula

These formulas are rough estimation shortcuts used to predict construction material quantities from a building’s floor area. However, the values are approximate and must be verified against structural drawings and project specifications.

Steel Quantity: Building area × 25 kg/m² (rough allowance).

Concrete Quantity: Building area × 0.23 m³/m² (project-dependent allowance).

Brick Quantity: Calculate from wall dimensions, thickness, brick size, and openings.

Formwork Quantity: Estimate the contact area of formwork required for concrete.

Interior Plaster: Calculate the internal wall and ceiling surface areas.

Exterior Plaster: Calculate the external wall surface area.

Masonry Mortar: Calculate from brickwork volume and mortar-joint requirements.

Plaster Mortar: Plaster area × specified thickness; for example, 20 mm plaster requires about 0.02 m³ of wet mortar per m² before allowances.

Important: These shortcuts are not universal standards. Accurate quantities depend on building design, materials, dimensions, and local specifications.
