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.
Open Windows Foundation
Again in collaboration with Developing World Connections, Open Windows builds houses for families in the area. While many families live in homes made of sheet metal with a dirt floor, these new houses are made of concrete blocks and have cement floors, which allow the families to keep them much cleaner. Volunteers work with masons hired by Open Windows to construct one-, two- or three-room houses, which represent a major improvement in the lives of the families.
