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.
Viet House Foundation
The operations of the foundation are simple. It costs about $3000.00 to build a basic house in Vietnam. As soon as the foundation receives enough money to build a house, the candidates' selection in Vietnam begins. It is important to note that 100% of the money raised will go to building houses. All other administrative and travel costs are covered by the family of the founder. Everybody who works in this operation, except for the construction workers, is an unpaid volunteer.
