Multipart pile cap for a foundation pile

Abstract

A multiple-part pile cap can include a top portion and a bottom portion that are configured to supply a mechanical interface between a first foundation pile providing a foundation for a structure and a frame of a structure itself. The multiple-part pile cap can be installed onto the first foundation pile of a set of foundation piles driven into the ground to provide the foundation for the structure using the multiple-part pile cap as the mechanical interface between the first foundation pile and the frame of the structure being secured to the first foundation pile. The bottom portion of the multiple-part pile cap can be i) matched in width to a width of a webbing of the first foundation pile and ii) has one or more holes in a first flange of the multiple-part pile cap to be bolted to the webbing of the first foundation pile.
