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
Viet House Foundation is an effort to raise funds to build basic houses in Vietnam for the poor people, usually impoverished single moms with small children living in deplorable huts. It was launched on the day after Thanksgiving Day in 2014. Within 3 weeks, it received enough donation to build the very first house which was transferred to the recipient in March 2015 in Can Gio, Vietnam. Within 2015, the foundation built three houses and got a start on Viet House #4.
