1. **Problem Statement:** Calculate the measurement for site clearance for the substructure of a warehouse using the given foundation plan dimensions. 2. **Given Data:** - Foundation outer dimensions: 50.00 m (width) x 30.00 m (height) - Foundation includes a boundary area between inner and outer rectangles (details not numerically specified) 3. **Formula and Explanation:** Site clearance typically involves clearing the entire site area where construction will occur. Area of site clearance = Length × Width 4. **Calculation:** $$\text{Area} = 50.00 \times 30.00 = 1500.00\, \text{m}^2$$ 5. **Interpretation:** The site clearance area is 1500 square meters. --- 1. **Problem Statement:** Calculate excavation and earthwork volume for the foundation. 2. **Given Data:** - Foundation footing dimensions: 450 mm wide, 300 mm high - Foundation length and width are not explicitly given; assume full foundation perimeter equals outer rectangle perimeter minus inner rectangle (not numerically specified) 3. **Formula:** Volume = Area of foundation footing × Depth (height) 4. **Assumption:** Assuming foundation perimeter equals the outer rectangle perimeter: $$\text{Perimeter} = 2(50 + 30) = 160\, \text{m}$$ Assuming footing width = 0.45 m, height = 0.30 m Volume = Perimeter × Width × Height 5. **Calculation:** $$\text{Volume} = 160 \times 0.45 \times 0.30 = 21.6\, \text{m}^3$$ --- 1. **Problem Statement:** Calculate disposal volume. 2. **Explanation:** Disposal volume equals the volume of excavated material minus volume used for filling or construction. 3. **Assumption:** Assuming disposal volume equals excavation volume (21.6 m³) minus volume of concrete and hardcore. 4. **Concrete volume:** - Floor slab thickness = 0.3 m - Hardcore thickness = 0.45 m - Area = 50 × 30 = 1500 m² Concrete volume = Area × thickness = 1500 × 0.3 = 450 m³ Hardcore volume = 1500 × 0.45 = 675 m³ 5. **Disposal volume:** Assuming all excavated material is used, disposal volume = 0 m³ --- 1. **Problem Statement:** Calculate filling to excavations volume. 2. **Given:** - Hardcore layer thickness = 0.45 m - Area = 1500 m² 3. **Formula:** Volume = Area × Thickness 4. **Calculation:** $$\text{Volume} = 1500 \times 0.45 = 675\, \text{m}^3$$ --- **Final answers:** - Site clearance area: 1500 m² - Excavation volume: 21.6 m³ - Disposal volume: 0 m³ (assumed all material reused) - Filling volume: 675 m³
