UW's fundraising is not really different from GT with the exception that the A-T Fund is perceived to be autonomous, which it isn't. The folks at the A-T Fund report to the Office of Development, just like those raising funds like Roll Call for the GT Foundation. UW has the Division of Intercollegiate Athletics under the UW Foundation, which is similar.
The Bylaws of the GT Foundation include the description of their Development Committee, which reads as follows (bold portions for emphasis):
Section 7. Development Committee. The Development Committee is charged with the responsibility of working with GIT, the Office of Development and other fund-raising entities, including the Athletic Association, Alumni Association, the various schools and colleges, and President’s office, to develop and coordinate fund-raising activities, programs and campaigns, including any funding thereof by the Foundation.
