This device (26) for verifying the bearing capacity of a first pile (22a) of an offshore foundation construction comprises a body (28), a first means for connecting the body (28) to a referential element, a second means for connecting the body (28) to the first pile (22a), a means for applying (34) a load on the first pile (22a) in a direction parallel to the axis of the first pile (22a). It further includes a means for measuring a displacement of the first pile (22a).

A solar array support structure includes a first vertical pile extending from a ground to a first pile end, a second vertical pile extending from the ground to a second pile end, and a first pile cap attached to each of the first and second vertical piles, the first pile cap configured to account for a misalignment of at least one of the first vertical pile and the second vertical pile by providing for adjustable attachment locations for each of the first and second pile ends.

Drill bits are provided for a drilling while driving machine. In some cases, the drill bit is a multi-stage bit capable of selectively cutting at two different diameters. In others, the bit is an expanding bit that can be passed through a foundation component while its being driven. The bit has a pair of cutting wings that can move between a retracted orientation where the bit's diameter is narrower than the inner diameter of the driven component, to a splayed orientation where the diameter is equal to or larger than the driven component's outside diameter.

A machine for rotary driving screw anchors into underlying ground and related. The machine has a mast with a rotary driver and a mandrel driver oriented on a common axis. The mandrel driver passes a mandrel through the rotary driver and the screw anchor to allow the mandrel to be actuated ahead of the screw anchor while the rotary driver drives the screw anchor into the ground. Alternatively, the mandrel driver may also drive a hammering drill through the screw anchor to clear a path ahead of it through subsurface rocks.

An alignment and installation jig for a screw anchor driving machine. The alignment and installation jig includes a laser target that can be moved from an alignment position to a driving position. The jig may also include one or more automated crimping assemblies to form permanent connections between overlapping foundation components while the machine is correctly oriented.

Method of building a grid system wherein a plurality of modular apparatuses can be arranged at a structure site. The plurality modular apparatuses can have a central tubular member having an inner bore formed between a proximal end and a distal end, and a plurality of vanes having a lateral width at least equal to a diameter of the central tubular member. The one or more modular apparatuses can be positioned above a surface of the structure site. Each of the plurality modular apparatuses can be connected with at least two adjacent modular apparatuses of the plurality of modular apparatuses via a locking lug on one of the plurality of vanes slidingly engaged with a locking channel on an adjacent modular apparatus. The plurality of modular apparatuses can then be driven into the structure site wherein the inner bore receives earthen formation therein.
