How to Calculate Construction

What is Construction?

Construction calculators cover materials estimation for building projects: concrete volume, brickwork, roofing, timber framing, and structural load calculations.

Formula

Concrete: Volume (m³) = Length × Width × Depth

Step-by-Step Guide

  1. 1Concrete: Volume (m³) = Length × Width × Depth
  2. 2Bricks: (Area / Face area of brick) × waste factor
  3. 3Roofing: plan area / cos(pitch angle) = actual roof area
  4. 4Timber: count linear metres of joists, rafters, and noggins

Worked Examples

Input
Concrete slab: 5m × 4m × 0.15m deep
Result
Volume = 3 m³; at 2,400 kg/m³ = 7.2 tonnes
