Optimized production of different structural components in a factory makes it possible to keep the construction site dry and clean, as after the components have been unloaded they only need to be assembled, fastened and screwed. Thanks to the use of such support systems as scaffolding and sometimes crane the need to use stationary logistical structures is eliminated. Calculation of the size of all elements, panels and roofs allows accommodating a building site, even in the most inaccessible places without harming the environment.
