Stock Photo - ***MARCH 31, 1977, FILE PHOTO*** The Research Institute of Civil Engineering Prague-Hostivar, the Agricultural Building Association Blansko and the Brno plant of Agroprojekt Prague have developed a system that allows designers to design buildings for livestock breeding in 84 variants using a modular system. Almost 1 million kg of steel per year and a commensurate amount of energy, extraordinary transport costs, assembly mechanisms, construction time and, last but not least, agricultural land will be saved by solving a national research task - new construction sets for large-scale agricultural buildings. Frantisek Kucera, a member of the Blansko Regional Council, welds the head of the columns of a new structural system for large-capacity cowsheds using a semi-automatic machine in a protective C02 atmosphere.
