Foundation (engineering)
A foundation is the element of a structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (Geotechnical engineering) in the design of foundation elements of structures.
Foundation (United States law)
A foundation in the United States is a type of charitable organization. However, the Internal Revenue Code distinguishes between private foundations (usually funded by an individual, family, or corporation) and public charities (community foundations and other nonprofit groups that raise money from the general public). Private foundations have more restrictions and fewer tax benefits than public charities like community foundations.
