You are required to design an individual shallow foundation for two types of office: A single-storey office A. B. A double-storey office Two criteria must be included into your design, which are: 1. 2. Loading i) Estimate the working load (WL) to be transferred to the ground for all types of the office ii) If the loading is directly applied at the center of the footing. iii) If the loading is applied eccentrically but vertically to the center of footing where e = 0.2m at length direction (L-direction). iv) Consider the self-weight of the footing (unit weight = 24 kN/m) and weight of soil above the footing. Your designs are required to meet 2 specifications: 1) The bearing resistance of the soil with over design factor r >2 ii) The total settlement limit is 50mm. Draw the layout of each footing for the two different working loads.
