Cleaning facilities are provided on all floors. Designed two stairwells (No. 3 and No. 4) for climbing to the 2nd and 3rd floors and evacuation with access directly to the outside. In staircase No. 4 (in axes 9-9/1, A-B) a vertical lift is provided for lifting disabled people from the 1st floor to the 2nd floor. Exterior finishing of facades: basement of the building up to +0,900 - porcelain stoneware cladding, brick or reinforced concrete walls of the building above +0,900 - insulation and porcelain stoneware decoration according to the ventilated facade system or sandwich panels. The covering of the building is flat, combined, with an organized internal drain. The height of the parapet is not less than 0,6 m. There are exits to the roof via external vertical metal stairs. Water intake funnels - with electric heating. Filling window openings - metal-plastic window blocks with double-glazed windows. Stained-glass windows - aluminum with two-chamber double-glazed windows. The decoration of the premises is provided in accordance with their functional purpose. The project documentation provides for measures to prevent criminal manifestations, including: in the lobby on the 1st floor there is a security room for access control, as well as a switching room on the 1st floor and a control room on the 3rd floor. The accessibility of the swimming pool building for students with disabilities, including swimming pools, changing rooms, showers and sanitary facilities (1 and 2 floors of the building) has been ensured. In staircase No. 4, a vertical lift is provided for lifting disabled people from the G floor to the 2nd floor. The evacuation of disabled people from the 2nd floor is provided for in the safety zone in stairwell No. 4 (in axes 9-9/1, A-B).

Structural and space-planning solutions

Pool building.

Building responsibility level - II. The pool building is designed from two blocks (sports and administrative-household), separated by an expansion joint. The building was designed according to the frame structural scheme, the basement was designed according to the mixed structural scheme. The outer walls of the basement are monolithic reinforced concrete 300 mm thick, class B25, R100, Zh6 concrete on sulfate-resistant cement, class A500C reinforcement. The outer enclosing walls are designed as brick, 250 mm thick, insulated with a ventilated facade system (developed at the design and development stage and must have a technical certificate from the State Construction Committee), as well as in the form of stained-glass windows and hinged sandwich panels (thickness 300 mm). Partitions are designed from tongue-and-groove hydrophobized slabs 160 mm thick (2x80 mm). The columns are monolithic reinforced concrete. The main column spacing is 6x6 m in the administrative part and 15,2x6 ​​m in the sports part of the building. Section of columns 400x400, 600x400 and 700x400 mm, concrete B25. Ceilings and covering over the administrative part - monolithic reinforced concrete slabs 200 mm thick on monolithic reinforced concrete beams with a section of 400x350 mm. Concrete B25. The covering over the sports part is precast prestressed reinforced concrete slabs of the TT3000 type, 700 mm high. The spatial rigidity and stability of the building is ensured by the joint work of stiffening frames, stiffening cores formed by the walls of stairwells, hard disks of floors. Pool bowls with dimensions of 10x6 and 25x11m are designed in monolithic reinforced concrete (B25; \U8). The thickness of the walls is 200 and 300 mm, respectively. The bottom of the pool is a beamless slab 200 and 300 mm thick, respectively, based on monolithic reinforced concrete walls 400 mm thick and columns with a section of 400x400 mm. Waterproofing is carried out according to the technology of a specialized organization. Stairs are designed from monolithic reinforced concrete, B25 concrete. The calculation of load-bearing structures was carried out on a computer. The foundations are made of slabs, 500 mm thick, on a natural foundation. Concrete class B25, I00, 'U / b on sulfate-resistant cement, reinforcement class A500C. The relative mark of 0,000 corresponds to the absolute mark of 13.45. In accordance with the report on engineering and geological surveys, light silty semi-solid loams with cp=24°, c=0,28 kg/cm2, E=140kg/cm2 serve as the basis for foundations. The design resistance of the foundation soils is not less than K = 6,26 kg / cm2, the pressure on the foundation soil is not more than p = 0,775 kg / cm2. The maximum groundwater level is near the daylight surface. Groundwater is non-aggressive to concrete of normal permeability. The soils are slightly aggressive towards concrete of normal permeability in terms of sulfate content. In order to protect the concrete of underground structures, the concrete grade for water resistance was adopted \U6 on sulfate-resistant concrete, the concrete surface is protected by coating with bitumen twice. The design solutions provide for the internal waterproofing of the basement by applying the Lakhta waterproofing composition and the outer waterproofing of two layers of Isoplast to the surface. The expected draft of the building is not more than -3,1 cm.
