Square concrete piles are arranged in 5 row by 5 column formation beneath the pile cap. These piles are embedded into several layers of cohesive soil. The first layer is 3.75m deep and the second layer is 4.49m deep. The total depth of the third layer was not fully captured in the geotechnical report and is assumed to extend indefinitely.

Question
Square concrete piles are arranged in 5 row by 5 column formation beneath the pile cap. These piles are embedded into several layers of cohesive soil. The first layer is 3.75m deep and the second layer is 4.49m 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 0.60m wide. Each pile span 12.59m in length. The first layer has c = 61 kPa and α = 0.99. The second layer has c = 82 kPa and α = 0.78. The third layer has c = 81 kPa and α = 0.63. The bearing capacity factor Nc is equal to 8.
What should be the spacing (m) to get a group efficiency of 111%? Consider ultimate capacities.
