Dig footprint22.00 × 17.00 m
Retained face (shoring / piling area)273 m²

Excavations deeper than about 1.2–1.5 m (4–5 ft) need sloping, benching, shoring or a trench box under most safety rules.

Basement excavations usually need a temporary works design for shoring, dewatering and neighbouring structures.

Working
  1. Footprint = (20.00 + 2 × 1.00) × (15.00 + 2 × 1.00) = 22.00 × 17.00 m
  2. Volume = 22.00 × 17.00 × 3.50 = 1,309 m³
  3. Loose = 1,309.00 × (1 + 25%) = 1,636.25 m³; loads = ⌈1,636.25 ÷ 10.0⌉ = 164
  4. Days = ⌈164 loads ÷ 60 per day⌉ = 3
