Methods for calculating technological and functional tolerances in the manufacture and installation of steel structures are described. An experimental installation of the structure was carried out to make it possible to clarify the tolerances, and the foundations of the methodology for assessing the qualitative and quantitative manufacturability of assembly elements were put forward to simplify the processes of manufacturing and assembling the structure.
