At the roof level superstructures are designed - ventilation chambers with an entrance from the roof. The building has 4 staircases and two elevators - passenger and cargo-passenger with the possibility of transporting fire departments. All staircases have direct access to the outside. The facades of the building are face brick. The basement of the building is lined with artificial stone. Over the entrances, visors are provided to protect against precipitation. Partitions are designed from hollow and solid bricks (in rooms with wet conditions). The premises of the school are finished depending on the purpose of the premises. All finishing materials are certified. Filling of window openings - a metal-plastic profile with two-chamber double-glazed windows. Stained glass - double-glazed windows. The design documentation provides for a flat, combined, roofing with an internal drain. Access to the roof is provided from the volumes of staircases and external metal stairs. The project documentation provides for measures to prevent criminal manifestations, including a security room and access control; installation of a metal fencing of the territory is also provided. The project documentation provides for measures to ensure access and training of MGN: ramps are provided for climbing to the level of the first floor, an elevator, anti-slip coating on the paths of the disabled, the floors are designed without height differences. The building provides universal sanitary cabins.

Structural and space-planning solutions

Building responsibility level – II (normal). The building was designed according to the combined structural scheme. The building is divided by sedimentary seam into two blocks. The basement floor was designed according to an incomplete frame scheme, with external load-bearing walls. The upper floors - according to the frame-wall structural scheme with a frameless frame. The outer walls of the basement are multi-layer, made of monolithic reinforced concrete 500 mm thick with an inner layer of insulation and an outer layer of reinforced concrete 140 mm thick. The internal walls of the basement are monolithic, 200 mm thick. Ceilings above the basement - monolithic reinforced concrete beamless continuous slabs 250 mm thick. The material of the bearing underground structures is monolithic reinforced concrete, concrete class B25, F100, W6, reinforcement class A500C. The frame columns are designed according to a grid of 6,0 x 6,0 m, the maximum step is 6,6 x 6,6 m. The frame columns have a section of 400 x 400 mm. The walls of the stairwells are monolithic, 200 mm thick, the outer parts of the walls are insulated and lined with bricks. Interfloor floors and roofing - monolithic reinforced concrete beamless continuous slabs 200 mm thick. The coating in the area of ​​the sports and assembly halls provides for the installation of monolithic reinforced concrete beams with a section of 400 x 500 (H) and 400 x 700 (H) mm. The cover over the pools is designed from profiled flooring along steel girders from rolled profiles, laid on steel trusses from closed bent-welded profiles of rectangular and square sections, the maximum span of trusses is 12,0 and 18,0 m, the step is 6,0 m. The coupling of trusses with columns is articulated. The rigidity and stability of the coating structures is provided by a system of vertical and horizontal connections. The structures of the stairs are monolithic reinforced concrete marches and platforms. The elevator shafts are monolithic reinforced concrete. The material of load-bearing ground structures is monolithic reinforced concrete, concrete class B25, F75, reinforcement class A500C. The structures of the bowls of the large and small pools are designed from monolithic reinforced concrete class B25, the thickness of the walls and bottom is 300 mm. The load from the pools is transferred through the monolithic walls to the grillage slab. External walls - self-supporting, lightweight masonry 640 mm thick from porous bricks M150, F50 and facing bricks 120 mm thick. In the pool area - from a solid brick 510 mm thick, a layer of insulation and an external facing brick 120 mm thick. The connection of the layers and the fastening of the walls to the supporting frame is carried out by flexible connections with an anti-corrosion coating. The internal walls are made of clay hollow brick M150 250 mm thick. The spatial rigidity and stability of the building is ensured by the joint work of columns and stiffening diaphragms, united by hard disks of floors. The load-bearing structures were calculated using the Lira 9.6 program, taking into account the joint work of the building with the foundation. The relative mark of 0,000 corresponds to the absolute mark of 26,95. The foundations of the building are piled. Piles - prefabricated reinforced concrete with a section of 35 x 35 cm, length 17 - 20 m, made of concrete of class B 25, W6, F100, immersed by indentation. In accordance with the report on engineering and geological surveys, the lower ends of the piles are immersed in the soils: EGE-8 - dusty gray sandy loam with gravel, pebbles with thickened interlayers of sand, hard (E = 210 kgf / cm2, JL = -0,22, e = 0,386). The expected design draft is 3,0 cm. The calculated pile load of 80 tf was taken on the basis of static sounding. The project provides for control tests of 6 piles. Grillage - slab, 500 mm thick, from monolithic reinforced concrete of class B25, W6, F100. Pairing of piles and grillage is rigid. Under the grillage, concrete preparation is provided from concrete of class B 7,5 with a thickness of 100 mm. In order to protect the concrete of underground structures, the concrete grade for water resistance is W6, waterproofing of surfaces in contact with the ground, and drainage are provided. The project provides for the fencing of the school territory and the installation of a noise barrier along the southern and eastern sides of the site. Bearing elements are designed in steel structures. Foundations for fence posts and screens - columnar, from monolithic reinforced concrete of class B25, W6, F100, on a natural base.
