1. Suppose you are to construct a column footing for your project. The 600x600x250mm footing has its top surface located at 650mm below the NGL. If 50mm is allotted underneath the bottom surface of the footing for its gravel bedding, and that the soil is very stiff that the exact perimeter of footing can be excavated in the ground, what is the total volume of soil that needs to be excavated? 2. Based from the previous question, if you are to put backfill in the excavated column footing given that the column has a 300x300mm cross-sectional dimension, determine the volume of backfill. Assume that the soil is very stiff that the soil does not require being compacted upon backfilling it. 3. Based from the previous question, what is the total volume of concrete required for the column footing? Ignore the volume of rebars in the column footing due to its steel reinforcements. 4. Based from the previously obtained value for the total volume of concrete for the column footing, how many bags of cement is required if Class AA concrete is preferred? Use method 1 in estimating the proportions of concrete components. 5. Based from the previously obtained value for the total volume of concrete for the column footing, how many cubic meters of sand is required if Class C concrete is preferred? Assume that there would be eight column footings required. Use method 1 in estimating the proportions of concrete components. 6. Based from the previously obtained value for the total volume of concrete for the column footing, how many cubic meters of gravel is required if Class D concrete is preferred? Assume that there would be eight column footings required. Use method 1 in estimating the proportions of concrete components.
