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.
Private foundation
A private foundation in Sweden (Stiftelse) is formed by a letter of donation from a founder donating funds or assets to be administered for a specific purpose. A private foundation may have diverse purposes, including collective, familiar, or the purpose of passive administration of funds. Normally, the supervision of a private foundation is done by the county government where the foundation has its domicile, however, large foundations must be registered by the County Administrative Board (CAB), which must also supervise the administration of the foundation. The main legal instruments governing private foundations in Sweden are those that regulate foundations in general: the Foundation Act (1994:1220) and the Regulation for Foundations (1995:1280).
