In October 1949, the authorities established a General Directorate to oversee both the works and the penal facilities, answering directly to the national leadership. Its first head was Gheorghe Hossu a former mechanic and tractor driver who had been promoted first-secretary of the Romanian Worker's party in Tulcea County and administrator of the State Fisheries. He was replaced in 1951 by Meyer Grünberg, in turn replaced by Mihail Povstanschi under the name of Vasile Posteucă, who held the position from 1952 to 1953. According to historian Adrian Cioroianu, all three were insufficiently trained for the task they were required to accomplish. By 1952, the Directorate came under the direct supervision of the Internal Affairs Ministry, and the Securitate was allowed direct intervention on the construction site.
