Apparatus and methods for the installation of pipe pilings into the ground for use as structural building foundations, geothermal piles, or both, are disclosed. In addition to specialized fittings for pipe pile assemblies, the inventions include specialized drive mechanisms used in conjunction with rotary or vibratory motors. Methods of installing pipe pilings are further improved with the disclosure of methods of adding grout or similar materials during or after installation of the piles.

Extensible shells and related methods for constructing a support pier are disclosed. An extensible shell can define an interior for holding granular construction material and define a first opening at a first end for receiving the granular construction material into the interior and a second opening at a second end. The extensible shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the extensible shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the extensible shell to form a support pier.

An H-pile caisson includes side tabs that can be gripped by side-mounted clamps on a vibratory hammer so that the caisson may be lifted into position from a horizontal position, oriented vertically, and driven into the ground without readjustment of the clamping of the vibratory hammer. A bolted side-extending base plate provides a mounting surface for a pole while allowing a continuous section of the H-pile to be received directly by the vibratory hammer.
