Scientific and technical activity Institute specialists participate in the work of the Scientific Coordination and Expert Council on problems of resources and safe maintenance of structures, buildings and machines under Ukrainian government agencies. The institute participated in developing the Concept of State program to ensure technical safety in major metal structures. This Concept helped develop the scientific/technical program “Resource”, as well as also branch and regional programs, for creating a state policy on building safety and maintenance. The technical committee for standardization 301 “Metal building” was established to improve standardization in the building and building materials industries. The institute is authorized to execute functions of this technical committee secretariat. Engineering design activities Bridges The institute has designed pedestrian bridges in the following Ukrainian cities. Kyiv across the Dnieper River Zhytomyr across Teteriv River Korosten across Uzh River The institute also designed suspension bridges across the Angara River and the Ural River. A curvilinear bridge across the Dnieper River, with a lightweight steel roadway, was developed during the reconstruction of passage on the Dnieper Hydroelectric Station dam in Zaporizhzhia One of the important tasks of the institute in the start was the development of the all-welded Е.О. Paton bridge across the Dnieper River in Kyiv, executed in 1953 with the E.O. Paton Electric Welding Institute. In 2001, the design of bridge roadway reconstruction was developed. Towers The institute has designed all-welded high-rise TV towers in Kyiv, St. Petersburg, Yerevan, Tbilisi, and Kharkiv. It has also designed antenna masts that are over 260 m high for broadcasting stations, unified towers for TV re-transmitters and radio relay lines. V.N. Shimanovsky designed the 385 m Kyiv TV Tower for the USSR Ministry of Communications. Leading design, construction, and mounting organizations were involved in the erection of television
