747 Wing House
The 747 Wing House was built on the site where existing Duquette structures had burned. Some of the materials from the previous building were used as walkways. The use of the existing pad minimized site grading. The foundation used many of the existing concrete retaining walls but they were rebuilt and reinforced as required to meet new code regulations. This greatly reduced the amount of concrete needed to make the foundation and new walls. Because the wings are only supported in four primary places to the ground, the foundation was further minimized. Both main wings are held up entirely by the four large mounts that the engines originally hung from. By designing the weight distribution on the mounts, it allowed for the outside walls of the building to be made of high efficiency self-supporting glass instead of conventional load-bearing wooden walls. This maximizes solar gain for heating and allows the entire building to be opened to the outside. This also keeps it cool in the summers and minimizes the need for artificial light.
Private foundation (United States)
A private foundation is typically set up as a non-profit corporation that bears the name of its donors, but may alternatively be established as a trust. Donors specify the charitable purpose of the foundation (example: grants for cancer research, scholarships for the needy, support of religious goals) . During their lifetime, they may continue their charitable giving by making tax deductible contributions to the foundation. The foundation may also be funded with a bequest from the donors' will or trust or receive funds as the primary or secondary beneficiary of a qualified plan or IRA.The IRS reports that there were 115,340 private foundations in the U.S. in 2008, of which 110,099 were grantmaking (non-operating) and 5,241 were operating foundations. Approximately 75% of the private foundations file annually with the IRS.
