The Engineering Experiment Station was renamed the Georgia Tech Research Institute in 1984. A separate organization originally called the Industrial Development Council, changed its name to the Georgia Tech Research Institute in February 1946, and finally to the Georgia Tech Research Corporation in 1984. There are legal difficulties when an American university wishes to accept contracts from some entities, especially the federal government, so the second organization is a contracting organization. Most importantly, it allows the university to perform multi-year contracts that are not possible under state law, which requires that money received must be spent in the same fiscal year. The name change coincided with a shift in focus toward obtaining industrial research contracts in addition to its contracts with the federal government. GTRI expanded its footprint in the mid to late 1980s: the Centennial Research Building opened on the north end of the Georgia Tech campus in 1985, providing expanded lab and office space, and the electromagnetic radiation measurement range was established at GTRI's Cobb County research facility.
