The foundation is a trapezoidal footing of 6 m length and widths of 6 m and 2 m with burial depth of 3.2 m. The subsoil is gravelly sand with about 7% fines. Measuring from the underside of foundation, soil is liquefiable between 2 and 3 m and again between 6 m and 13 m. Some loose sand may still be present below 15 m. Thank you for your response in advance.

Thank you for the feedback. We think the loose sand may extend beyond the 16.5 m that was investigated. Would you still do piling if the loose sand extends even more than 20 m.

Thank you for all the comments.
Mercycity - Here are the SPT data just beside the footing of 18 ft by 12 ft. Groundwater assume 1.5 m bgl and D = 3 m.
