Waqar, For vertical spring values, you need to know deflection of your piles. That is obtained by first calculating load per pile, and calculating the deflection using geotechnical recommendations. Once you have load and deflection of a single pile, you can calculate the spring stiffness by load/ deflection. This is based on un-factored loads. For lateral spring values, geotechnical should provide you the values or lateral k values and you should consider pile group effects. See this discussion:
