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.

The disclosure presents a composite column formwork which utilizes a fiber reinforced polymer (FRP) stay in place container which incorporates horizontally coplanar support chairs bonded to the interior surface, closed ties bonded to the support chairs and a plurality of longitudinal rebar enforcements bonded to the closed ties. All of the components in a preferred embodiment are formed of a fiberglass material.

The disclosure presents a composite concrete structure formwork which comprises stay in place fiberglass profiles and reinforcement to form various building and shelter structures. The structures include an interior container maintained at a set distance within an exterior container to form a void. The void is filled with wet concrete which is allowed to cure. All of the components in a preferred embodiment are formed of a fiberglass material.

The disclosure presents a composite conduit formwork structure which includes a cylindrical outer casing adapted to bond with a cylindrical inner casing which are maintained at a fixed distance apart by a plurality of radial stanchions. The inner casing and outer casing form an interior void which is filled with concrete during manufacture. The outer casing and inner casing remain in place to protect the structure once completed. A novel method of assembly is also provided whereby radial stanchions are rotated between the outer casing and inner casing. All of the components in a preferred embodiment are formed of a fiberglass material.

Embodiments described herein relate to construction of subsurface structural elements that are configured to redirect soil forces. For instance, a form may be used to construct a subsurface structural element such that the subsurface structural element redirects soil forces to vertically displace a foundation rather than have the soil forces crack or otherwise damage the foundation.

A method of constructing a building is disclosed, including selecting a standard dimension less than a wide-load trucking permit limit and designing a building on a grid defined by the selected standard dimension. The building includes a plurality of prefabricated elements, wherein each prefabricated element has a width correspond to the selected standard dimension. The plurality of prefabricated elements includes a wall panel, a roof panel, a laterally resistive frame, and a rebar cage. The method includes fabricating each of the plurality of prefabricated elements at a manufacturing plant and transporting the elements by truck to a building site. The method includes constructing intersecting grade beam footings at the building site and pouring a slab between the intersecting grade beam footings. The grade beam footings include the rebar cage and have a uniform width and depth, the grade beam footings and the slab having contiguous upper surfaces.

The present invention is a modular structural building method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.
