Excavation:- Quantities are calculated based on the dimensions of the foundation in plans fromthe owner perspective.- Contractors should consider the excess of material excavated to all for safeoperations.- Prices differ based on the soil type, deep of excavation, ground water level, sitelocation, shoring system, Equipment used, etc.- Unit of measurement is cubic meter (volume).- Consider the following example (Figure 2.3).Fig. 2.3: Plan and cross section of building foundationThe length of excavation = 5.4 × 2 + (4.4 – 2) × 2 = 15.6 mDepth of excavation = 1.8 mWidth of excavation = width of plain concrete footing = 1.0 mVolume = 15.6 × 1.8 × 1.0 = 18.8 m 3- Consider another example (Figure 2.4). Plain concrete dimensions (1.2 × 2.0 × 0.2m), reinforced concrete footings dimensions (0.8 × 1.6 × 0.4 m); depth ofexcavation 1.2 m and ground beams cross section is (0.25 × 0.4 m).
