The building provides for an administrative and amenity 2-storey building. The building in terms of plan consists of 2 blocks: a 1-storey block measuring 24x78m (axes 1-14, B-K) and a 1-storey block measuring 12x48m (axes 3-11, A-B). The main entrance to the building is located in axes 8-9 along the K axis through the vestibule. Transportation of goods inside the warehouse is carried out by loaders. Since metal products are supposed to be stored in the warehouse building (category D), storage facilities may not be heated or ventilated. Therefore, the reconstruction project provides for the dismantling and dismantling of the existing ventilation chamber in axes 3-4, B-C. And in place of the ventilation chamber at around +3.600 in axes 7-11, B-C, a storage room is arranged. Delivery of goods to elev. +3.600 is carried out by pallet trucks.
