In 1893 Buinitsky began to teach about fortification in a native university, and became a professor.^[4] He co-operated with the Engineering Magazine, Military Collection, Artillery Magazine, Encyclopaedic Dictionary of Brokgauz-Efron, Encyclopaedia of Military and Marine Sciences, and the Military Encyclopaedia.^[5][6] In 1909, he became a member of the engineering committee, supervising creation of fortresses. His advanced studies have large value for the development of Russian fortifications, for example he was the supporter of the creation of integrated systems of fortifications.
