Foundation (engineering)
Foundations are designed to have an adequate load capacity depending on the type of subsoil/rock supporting the foundation by a geotechnical engineer, and the footing itself may be designed structurally by a structural engineer. The primary design concerns are settlement and bearing capacity. When considering settlement, total settlement and differential settlement is normally considered. Differential settlement is when one part of a foundation settles more than another part. This can cause problems to the structure which the foundation is supporting. Expansive clay soils can also cause problems.
Foundation (nonprofit)
In some jurisdictions, a foundation may acquire its legal personality when it is entered in a public registry, while in other countries a foundation may acquire legal personality by the mere action of creation through a required document. Unlike a company, foundations have no shareholders, though they may have a board, an assembly and voting members. A foundation may hold assets in its own name for the purposes set out in its constitutive documents, and its administration and operation are carried out in accordance with its statutes or articles of association rather than fiduciary principles. The foundation has a distinct patrimony independent of its founder.
