Geoss Guidelines On Local Practices For Pile Foundation | Design And Construction
Geotechnical engineers, site supervisors, and local building authorities Reference: GEOSS – Geotechnical Operational Safety Standards (working document, version for local practice integration)
From GEOSS table for West Africa: ( q_p = 20 \times N ) kPa (not 40×N). End-bearing: 20×18=360 kPa at 5m. Add skin friction: 0.4×N=7.2 kPa × 5m depth. Ultimate capacity per pile = 108 kN. Required for building load: 18 piles.
