Disclosed herein are a group anchor system, subsea installation tool and method of install such group anchor systems. The group anchor system includes a template through which a plurality of vertical piles, such as helical piles, are passed, drilled into the seabed at one end and secured to the template at the other to provide a mooring anchor for an offshore asset. The installation tool is a modular tool designed to mate with the group anchor system. Each module including drive mechanism for engaging and driving a pile. The piles may be driven simultaneously, individually, or in groups as required for proper placement and leveling. Methods of using the installation tool are also disclosed.

An erosion control securing apparatus and method is disclosed. For example, an erosion control securing device is provided that includes a main shaft with a hexagonal-shaped head portion at its proximal end and a coil portion at its distal end. In one example, the coil portion of the erosion control securing device includes three turns. Further, a method of using the presently disclosed erosion control securing device for securing erosion control products is provided.

The present invention relates to a building system and a method of making and assembling the building system. In particular, the present invention relates to a footing for a building structure, the footing comprises a plurality of precast concrete layers, each precast concrete layer comprising reinforcement bars and a plurality of apertures. The footing further comprises a base structure comprising a base plate and a plurality of alignment bars protruding from the base plate. The footing is configured such that when the plurality of precast concrete layers are positioned on top of one another, the plurality of alignment bars of the base structure extend through the respective apertures of each precast concrete layer. Furthermore, the present invention relates to a building structure having one or more building modules.

An anchor head mounted to or incorporated into the shaft of conventional tie down stakes and earth anchors. The anchor head eliminates the need to manually drive the earth anchor into the ground and allows the anchor to be placed and removed using conventional powered drill/drivers and hex sockets or wrenches. The anchor head has a hexagonal top section and a hexagonal bottom sectional separated by an integral, central annular shoulder. The top and bottom sections are each configured to have six equilateral side walls and dimensioned to receive two different sizes of wrench or hex socket. The bottom section of the anchor head has a threaded axial bore for receiving the threaded end of the anchor shaft. The bottom section also has a lateral “swage” bore through which a punch is inserted to swage or deform the threads of the shaft to permanently secure the anchor head to the shaft.

Systems and methods to provide pressed aggregate-filled cavities for improving ground stiffness and uniformity are disclosed. According to an aspect, a method includes using a mechanism to press into a ground surface in a substantially downward direction to create a concavity. The method also includes substantially or completely filling the concavity with unstabilized or chemically stabilized aggregate, soil, or sand. Further, the method includes using the mechanism to press the aggregate within the concavity to achieve a desired ground stiffness.

A rotary drive machine for the installation of helical pile sections through installation openings in a slab floor inside of a building perimeter. A vertical frame having an upper end and an open lower end is positioned over an installation opening through which it is desired to rotationally install a helical pile section, and the vertical frame anchored to the slab floor. A rotary power means, attached to the helical pile section moves along a vertical movement guide and is driven by a vertical actuator to rotationally and vertically drive the helical section into the ground. A method of use is also disclosed.
