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.

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 106 N excluding the weight of pile cap. Design and draw the plan of the most suitable friction pile group considering the following parameters:Cohesion intercept of clayey layer = 0.030 N/ mm2Factor of safety against shear failure = 2.25Weight of pile cap = 110000NPile diameter = 300 mm

A helical pile with 12 in diameter flights and a 2 in square rod is to be installed to a depth of 30 ft in a silty clay. The undrained shear strength is 1,000 lb/ft2 and the groundwater table is at a depth of 40 ft. The individual helixes are located every 5 ft along the length of the pile, and the pile has an average weight of 100 lb/ft (including the embedded soil). Using a factor of safety of 3, determine the ASD allowable uplift capacity, Pup,a.
A square prestressed concrete pile with a 14 inch side is to be driven to the necessary depth. It needs to be able to support 105 kips. It has been determined that the point resistance qp is 120 ksf and the side friction fs is 450 psf. Use formula 12.2 (see attached image) to estimate how long the pile needs to be with a factor of safety of at least 2.5. Round your answer to a multiple of 5 feet. Use L as a variable to calculate the load in formula 12.2. L can be obtained from this equation.
