Seawalls and methods for making seawalls are disclosed. A seawall may include a concrete footing, with a first plurality of anchorages disposed in the concrete footing. A plurality of precast concrete tee beams may include single-tee beams and/or double-tee beams. Flanges of the tee beams may be positioned to form seaward and landward faces of the wall, and stems of the tee beams may be coupled to the footing between the seaward and landward faces. A second plurality of anchorages may be disposed at tops of the stems. Elongate steel components extend through the stems, and are tensioned between the first plurality of anchorages and the second plurality of anchorages. Interior fill may be disposed between the seaward and landward faces. One or more wave deflectors may be disposed above the tee beams.

A building sheltering structure is configured to facilitate the shielding of domicile or building into an underground foundation before an emergency environmental condition arises. The foundation includes a cover plate and/or a second plate that translate horizontally to occlude the at least one domicile upon retraction into a secure cavity of the foundation by a lift assembly in the foundation cavity. The cover plate and second plate offer optimal protection to the domicile thereunder for various extreme conditions. Mounted atop the lift assembly, the at least one domicile can be fully retracted into the foundation cavity and completely shielded. The operation of the lift assembly is commanded and powered by a supply system, of which a processor facilitates emergency warnings and panic transmissions to signal for help. Further, a plurality of solar panels mounted atop the at least one domicile keeps the system charged for the use in emergency.

A system for forming a piling structure includes a hollow casing, a control assembly positioned proximately to the hollow casing, and a pivoting support device connected to the control assembly. A pivoting electrode is connected to the pivoting support device and configured to extend into the hollow casing. A second electrode is connected to the control assembly and extends into the hollow casing within the range of motion of the pivoting electrode. An electric power source is connected to the pivoting electrode and the second electrode, wherein charge on the electrodes produces a current arc between the pivoting electrode and the second electrode. A lift mechanism is positioned proximately to the hollow casing to control the electrodes position within the hollow casing.

A method for installing and deploying concealed mounting points for a davit or jib crane on a roof patio or large balcony covered with stone pavers. Specifically, a metal plate assembly lower flange is affixed to the concrete roof slab with its contact points covered by waterproofing membrane. The metal assembly hard point upper flange holes correspond to the holes in the mounting base of the davit or jib crane. The metal assembly when installed is lower than the pavers supported by metal pedestal transition components. As such, the metal assembly hard point is concealed and covered by a removable cover plate that also sits on top of the metal pedestal transition components and is flush with the top of the pavers.

A building sheltering structure is configured to facilitate the shielding of at least one domicile or building into an underground foundation before an emergency environmental condition arises. The foundation includes a cover plate that translates horizontally to occlude the at least one domicile upon retraction into a secure cavity of the foundation by a lift assembly positioned at the bottom of the foundation cavity. Mounted atop the lift assembly, the at least one domicile can be fully retracted into the foundation cavity and completely shielded by the cover plate. The operation of the lift assembly is commanded and powered by a supply system. A processor of the supply system facilitates emergency warnings and panic transmissions to signal for help. Further, the supply system accommodates a plurality of solar panels mounted atop the at least one domicile to keep the system charged for the use in emergency.

In a general aspect, a method is presented for manufacturing support structures for offshore wind turbines. In some implementations, the method includes constructing a plurality of modular sections that assemble to define the support structure. One or more of the plurality of modular sections are configured to anchor to an underwater floor. At least one of the plurality of modular sections is constructed by operations that include forming a wall along a perimeter to bound a volume, filling the volume with a castable material, and hardening the castable material. In some instances, forming the wall includes depositing layers of printable material successively on top of each other. The method also includes joining the plurality of modular sections to assemble the support structure.

Systems and methods for constructing concrete foundations are provided which allow for rapid and high-precision placement and alignment of anchor bolts across large distances. A frame system is constructed outside of an excavation and then suspended, using supports, over an excavation. The frame system can include a frame having one or more templates for anchor bolts, a form suspended from the frame, and a mat and cage assembly tied to the frame. The frame system can be aligned in proper position and the anchor bolts placed in the frame system before the concrete is placed. In this way, the anchor bolts can be cast in place as the footing is placed.
