Square concrete piles are arranged in 3 row by 4 column formation beneath the pile cap. These piles are embedded into several layers of cohesive soil. The first layer is 3.36m deep and the second layer is 3.42m deep. The total depth of the third layer was not fully captured in the geotechnical report and is assumed to extend indefinitely. The piles are 0.45m wide, and are spaced 1.45m apart from each other. Each pile span 11.89m in length. The first layer has c = 60 kPa and α = 1.00. The second layer has c = 87 kPa and α = 0.81. The third layer has c = 85 kPa and α = 0.70. The bearing capacity factor Nc is equal to 8.What is the group efficiency (%) for the pile? Consider ultimate capacities. Please answer this asap.

Compare circular, square and I section piles in terms of usage, cost and advantages/disadvantages?
During geological investigation on a site, it was observed that subsoil contains 7.5 m depth of clay followed by some other incompetent layers. The consultant decided to design a friction pile group which should be economical and able to carry the anticipated load of 1.5 x 10° N excluding the weight of pile cap. Design and draw the plan of the most suitable friction pile group considering the following parameters: = 0.030 N/ mm - 2.25 Cohesion intercept of clayey layer Factor of safety against shear failure Weight of pile cap = 110000N Pile diameter 300 mm %3D
