2. a. Compute the number of driven piles with a diameter of 0.8m and a length of 12m that are required to support a building whose permanent and variable loads are 4 MN and 1.5MN respectively. 3 cone penetration tests were conducted and gave an average base resistance of 11 MPa and a shaft resistance of 10MPa (10 marks) b. Using a neat sketch show the pile layout drawing with dimensions given that the building has a footprint of L-15m and W=10m (4 marks) c. Assess the group efficiency if the soil has a cu of 80kPa at the surface and 130 kPa at the 12m depth (6 marks)
