ABSTRACT:
A reduced skin friction driven pile which reduces the downward frictional force applied to the pile by the settling of compressible soils surrounding the pile after the pile is driven, comprising a pile which may include a friction reduction coating located about a portion of the exterior of the pile which is expected to have soils settling relative to it. Additionally, a friction reduction collar may be placed at a location along the pile which will create a void between the soil and the portion of the pile above the collar when the pile is driven, so that soils may settle relative to the pile with the void providing reduced contact between the settling soils and the pile so that the downward force of settling soils is reduced.
