Based in the results of a static load test, a certain pile has a net toe bearing capacity of 890kN and a side-friction capacity of 2225 kN.

4. Based in the results of a static load test, a certain pile has a net toe bearing capacity of 890kN and a side-friction capacity of 2225 kN. A series of these piles are to be driven in a 3x4 group which will have an estimated group efficiency of 1.15.

a. Compute the allowable downward load capacity of this pile group using a factor of safety 3.0.

b. Assume this group of piles are located in a clay medium and behave as floating piles, explain the steps on calculating the resulting settlement using the Terzaghi Peck method.

i found allowable downward load capacity 14329 Kn

But i dont know how can i approach second part of problem
