The design of the building involves the color scheme of the facades, lined with Kraspan aluminum composite panels according to the corporate identity logo. The internal finishing of the external walls (sandwich panels) is carried out under factory conditions, the facade cladding is a ventilated facade (Kraspan aluminum composite panels on the frame). Interior decoration is provided in accordance with the operational requirements of the premises. Ceiling in all main rooms - suspended, type "Armstrong", in sanitary facilities - slatted. Floors - ceramic tiles, non-slip, except for the premises of the manager, staff, mechanic, cash-in-transit (in these premises - a heterogeneous coating). Heated floors are provided at the location of the operator's stand, waterproofing with isoplast is provided in wet rooms and the compressor room. Windows - metal-plastic with double-glazed windows, two-chamber. In administrative and amenity premises - opening. Entrance external door - metal-plastic glazed with a door closer, Other external doors - metal insulated. On the evacuation routes from the trading floor and premises on the second floor - fire-fighting. Internal doors are wooden.

Structural and space-planning solutions

The building of the control room and the canopy are designed in a steel frame. Level of responsibility – II. The constructive scheme of the control room building is a full frame-and-braced frame. In the direction of the letter axes - frames, in the direction of the digital axes - a system of vertical connections. The spatial immutability of the frame of the control room is ensured by the joint work of frames, vertical ties, floor and roof beams, floor and roof hard disks. The ceiling is a monolithic reinforced concrete slab in a fixed formwork made of corrugated board. The thickness of the floor slab in the area of ​​the corrugated board rib is 160 mm, between the corrugated board ribs is 85 mm. Floor slab material - class B20 concrete. The rigidity of the coating disc is ensured by fastening the corrugated board to the beams in each wave on the extreme spans and through the wave on the middle spans. The sections of the main load-bearing structures of the frame were adopted: columns - square pipes according to GOST 30245-2003 from steel C245; roof beams - I-beam according to STO ASCHM 20-93 from steel C245, roof decking - H75-750-0.8 according to GOST 24045-94. As external enclosing walls, hinged wall panels of the “sandwich” type 150 mm thick are used, the coating is corrugated board, laid directly on the upper chords of the coating beams. A fachwerk system has been developed for fixing wall panels. The foundation for the control room building is a non-buried monolithic reinforced concrete slab 300 mm thick, with monolithic reinforced concrete back beams along the contour and under columns 600 mm high made of B25, W6, F150 class concrete. To prevent freezing of the base of the foundation slab, insulation with foam slabs is provided. In accordance with the report on engineering and geological surveys, the base is the EGE-1 layer (silty sandy plastic ferruginous sandy loam), which has the following characteristics: ρн=2.07 t/m3; e=0.575; Сn=0.27 kg/cm2; n =24о; E=110 kg/cm2. The average pressure under the sole of the foundation slab is 0.4 kg/cm2. The design resistance of the base soil is 1.1 kg/cm2. The expected settlement of the foundation slab is 1.0 cm. The spatial invariability of the canopy frame is ensured by the joint work of the columns, rigidly fixed with the portal, and the hard disk of the profiled flooring, which is fastened with self-tapping screws in each wave. The node of support of the main roof beams on the columns is decided to be rigid. Columns - I-beams according to STO ASChM 20-93 from steel C245, canopy beams are designed from I-beams according to STO ASChM 20-93 from steel C245, corrugated board - H75-750-0.8 according to GOST 24045-94 from steel C235. The foundations for the canopy columns are monolithic reinforced concrete columnar and monolithic reinforced concrete slabs 300 mm thick. The material of the column foundations is concrete of class B20, W6, F200, the material of slab foundations is concrete of class B25, W6, F200. Fuel tanks are also installed on the foundation slabs under the canopy columns. In accordance with the report on engineering-geological surveys, the base is the EGE-2 layer (fluid silty sandy loam), which has the following characteristics: ρн=2.01 t/m3; e=0.671; Сn=0.11 kg/cm2; n =18о; E=80 kg/cm2. The average pressure under the base of the foundation is 0.4 kg/cm2, the design soil resistance of the base is 2.0 kg/cm2. Expected draft - 2.0 cm. The design of the foundations provides stability against ascent. The design solutions provide for coating waterproofing of the outer faces of the foundations in contact with the ground. The required fire resistance of the load-bearing frame structures is ensured by painting with a special fire retardant composition of the Joker 521 type. The calculation of the main load-bearing structures was performed using the LIRA 9.6 software package. The maximum horizontal movement of the canopy frame is 1.48 mm. The displacements and deflections obtained as a result of the spatial calculation of the building frame do not exceed the maximum allowable values. The relative mark of 0,000 corresponds to the absolute mark of +15.300. The groundwater level during the survey period was revealed at a depth of 1.3-1.6 m from the earth's surface at absolute elevations of +13.50 - +13.10. The maximum level of groundwater is expected during periods of snowmelt and heavy rainfall is expected on the surface, at absolute levels of +14.80 - +14.70.
