In 1961, construction began on two new wings, which were added to the eastern ends of the building, along with additions to the library and physics wing. The expansion, dedicated in October, 1963, was prompted by a $3.4 million contract awarded by the Advanced Research Agency of the Department of Defense. In 1973, a new entrance terrace was dedicated. By the end of the 1980s, the building was again in need of repair. After a $30 million grant from the McCormick Foundation in 1989, the school was renamed in honor of Robert R. McCormick.[3]
In 1999, a ten-year, $125 million renovation of the Technological institute was completed. This renovation, undertaken by Skidmore, Owings & Merrill, included extensive reconstruction of the interior of the original 1940 structure, replacing the mechanical, plumbing, and electrical systems, and reconfiguring the laboratory and research space.[4]
Additional buildings have been constructed around the original Technological Institute, connected together by pedestrian bridges to create what has been called the "Technological Campus". Among them are the Seeley G. Mudd Library for Science and Engineering opened in 1977, the Center for Catalysis and Surface Science in 1986, and Cook Hall in 1989. More recent additions to the "Technological Campus" include Hogan Hall, the Pancoe Life Sciences Pavilion, the Center for Nanofabrication, and the Ford Motor Company Engineering Design Center.
