A system and method for constructing an insulated concrete form (ICF) wall are provided. Vertically-oriented pairs of ICF foam panels of an ICF structure are erected above a footing, with vertical panel supports located along opposed vertical edges of each set of adjacent vertically-oriented panel pairs. An internal brace support, extending longitudinally along the structure, is installed between the individual panels of the panel pairs. Concrete is poured between the erected vertically-oriented ICF foam panels to complete the ICF wall.

A foundation device able to support two different sized posts. The foundation device comprising a platform; a base located below the platform with the base being connected to the platform by an outer support wall; an inner support wall extending upwardly from the platform, the inner support wall being separated into four inner wall sections that define a first beam channel and a second beam channel; and a post recess centrally located within the platform, a floor of the post recess being located lower than that of the platform.

A wind turbine foundation comprising a concrete support slab having a horizontal rebar grid therein, a concrete pedestal integral with the support slab and having vertical post tensioning elements therein and a plurality of concrete ribs on top of and integral with the support slab and integral with the pedestal, the ribs having rebar therein and extend outwardly from the pedestal, the pedestal, slab and ribs are connected to each other to form a monolithic foundation. The foundation design reduces the and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

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.
