The schemes are designed for dismantling the production building T1 in the axes 1-7 J-N. The dismantled section of the production building is a one-story frame building measuring 36x24m in plan and 10.8m high inside the building. The building frame is made of reinforced concrete structures: columns with a height of 10.8 m and a cross section of 800x400 mm are arranged in increments of 12x18m; trusses have a span of 18m and a height of 3m; ribbed slabs, two sizes 12x3m and 12x1.5m. Building envelope - wall panels (-1.0; 1.2; 1.8m high) 6m long and 300mm thick. The half-timbered columns are reinforced concrete, with a section of 300x400 mm. In the axes 7 J-M section of the wall thickness. 250mm to mark 6.6m is made of silicate brick. Between the columns in the longitudinal direction at around 8.0 m there are horizontal ties representing a rigid spatial metal structure. In the axes 1, 4, 7 J-L are vertical ties, representing a rigid spatial metal structure. Inside the enclosure 7.2 m along the reinforced concrete columns in the longitudinal direction are the metal beams of the bridge crane tracks. The dismantled section of the housing T1 from the side of the axis 7 M-N is adjacent to the housing T2, and from the side of the axis 7 J-N to the body to be dismantled. To carry out the dismantling of frame elements, it is planned to use the RDK-250 crawler-mounted crane (boom-25.3m; rigid jib-5m) as a lifting mechanism, and AGP-18.04 aerial platform as a means of lifting.
