volume of the excavated material (see Figure 2.4). Distance between centerlines is5 m.Fig. 2.4: Footing foundation plan and cross sectionExcavation for footings = 2 × 1.2 × 2.0 × 1.2 = 5.76 m 3Excavation for smell = (5 – 2 × 1) × 0.6 × 0.25 = 0.45 m 3Volume = 5.76 + 0.45 = 6.21 m 3Backfilling:- Unit of measurement is cubic meter (volume)- Backfilling = Excavation – volume of all works inside the excavated pit (footings,smells, column necks, brickwork, etc.) + amount above GL (or – amount belowGL) as shown in Figure 2.5.Fig. 2.5: Backfilling quantities calculationsCost Estimating 30 Dr. Emad Elbeltagi
