A pile is a slender timber, concrete, or steel structural element, driven, jetted, or otherwise embedded on end in the ground for the purpose of supporting a load. A pile is also characterized as deep foundation, where the loads are transfered to deeper subsurface layers.
NOTE Definition according to ISO 6707-1: slender structural member, substantially underground, intended to transmit force(s) into loadbearing strata below the surface of the ground.
NOTE Shallow foundations, which transfer the loads to the ground near its surface, are represented by IfcFooting.
