A method for forming a foundation wall of a building structure having a building frame seated on the foundation, the method including coupling each of a plurality of elongated vertical members to a floor of the foundation and the building frame so that each of the vertical members extend between the floor and the building frame adjacent to an existing foundation wall, providing at least one elongated horizontal member through apertures of the vertical members such that the horizontal member extends between and passes through respective ones of the vertical members, coupling panels to the horizontal member so as to form, with the vertical members and the horizontal member an integrated self-supporting formwork which, with the existing foundation wall forms a cavity, having disposed therein, the vertical members and the horizontal member, and flowing concrete into the cavity so as to fill the cavity around the vertical members and horizontal member disposed within the cavity.

A retrofit reinforcing structure addition and method for an existing gravity spread foundation for a wind turbine or the like having a central pedestal and a spread section is provided. The retrofit structure addition includes a collar formed around the pedestal of the spread foundation. The collar is formed by a shape sustaining member, such as a CMP, placed around the pedestal to define an annular ring between the CMP and the pedestal that is filled with cementitious material. Radial bolts extend horizontally through the collar and into the side of the pedestal. Soil and/or rock anchor bolts extend vertically through the collar, the spread portion of the foundation and into the underlying soil and/or rock substrate. The radial and anchor bolts are post-tensioned to ensure that the cementitious material of the collar remains in compression and the bolts are always in static tension, strengthening the original gravity spread foundation and extending the fatigue life thereof.

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.

A method for forming a foundation wall of a building structure having a building frame seated on the foundation, the method including coupling each of a plurality of elongated vertical members to a floor of the foundation and the building frame so that each of the vertical members extend between the floor and the building frame adjacent to an existing foundation wall, providing at least one elongated horizontal member through apertures of the vertical members such that the horizontal member extends between and passes through respective ones of the vertical members, coupling panels to the horizontal member so as to form, with the vertical members and the horizontal member an integrated self-supporting formwork which, with the existing foundation wall forms a cavity, having disposed therein, the vertical members and the horizontal member, and flowing concrete into the cavity so as to fill the cavity around the vertical members and horizontal member disposed within the cavity.

A locking track for a wall reinforcement system comprises a top panel, two opposing side panels, a channel defined between the top panel and the two opposing side panels, and locking tabs formed in the two opposing side panels and extending into the channel. The wall reinforcement system further comprises a post. The post comprises a web, two flanges extending transversely from the web, and at least one slot formed in each one of the two flanges. The post is attachable to the locking track, and when attached, the at least one slot formed in each one of the two flanges receives a corresponding one of the locking tabs to lock the post to the locking track.

A steel cap for structurally connecting together a new foundation and an existing tower is disclosed. The new foundation includes at least one foundation element positioned in the ground. The existing tower includes an existing foundation and a tower structure extending from and supported by the existing foundation. The steel cap comprises (a) a first element for connecting the cap to the new foundation element or foundation elements and (b) a second element for connecting the cap to the existing tower and thereby, in use, connecting together the new foundation and the existing tower.
