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)
The Tax Reform Act of 1969 defined the fundamental social contract offered to private foundations. In exchange for exemption from paying most taxes and for limited tax benefits being offered to donors, a private foundation must (a) pay out at least 5% of the value of its endowment each year, none of which may be to the private benefit of any individual; (b) not own or operate significant for-profit businesses; (c) file detailed public annual reports and conduct annual audits in the same manner as a for-profit corporation; (d) meet a suite of additional accounting requirements unique to nonprofits.
