On the mezzanine at around 3,600 are designed: administrative premises, a hall, a negotiation room, a server room, bathrooms and a ventilation chamber. On the third floor at around 8,700, an open-type car park for 26 cars has been designed. A single-track, weather-protected ramp with a slope of 13% was designed for lifting vehicles. For the evacuation of people, a sidewalk is provided along the edge of the ramp. Roof for open type car park - operated with an internal drain. The surface is asphalt concrete. The roof is unexploited with an internal drain. Coating - EKP technoelast with powder. Anti-aircraft lamps and engineering equipment are designed on the roof. External walls - sandwich panel on a metal frame. The main entrance is lined with natural stone (black slate). The plinth is lined with ceramic granite slabs. Filling of window and stained-glass openings - single-chamber double-glazed windows, in administrative premises - with energy-saving glass. The design documentation provides for measures to ensure the accessibility of the facility for people with disabilities and people with limited mobility, including wheelchair users. Entrances to the building, adapted for MGN, are located on the same level with the ground level and do not have thresholds. There are 6 parking spaces for MGN in the parking lot. The width of the parking space is 3,5. On the 1st floor of the parking lot, there are 6 places for MGN with a width of 3,5 m. The accessibility of people with limited mobility to the premises of the 1st floor is provided. The width of the corridors on the path of movement of the MGN is assumed to be at least 1,2 m. On the 1st floor (at elevation 0,000) there is a universal sanitary cabin for MGN. The bathroom for MGN is equipped with special sanitary equipment. Entrance and internal doors are designed as swing doors.

Structural and space-planning solutions

The parking building is designed in a bonded frame and is divided into 3 blocks by temperature-settlement seams. Building responsibility level - II (normal). Spatial rigidity and stability of the building blocks is ensured by the rigid fastening of the columns on the supports, the presence of diaphragms and stiffening cores and hard disks of floors and roofs. Main bearing elements: monolithic reinforced concrete frame columns and piers with a section of 300x500 mm, 300x700 mm, 200x700 mm and 200x600 mm and, in part, steel frames of their box-section elements; walls of stairwells and stiffening diaphragms - monolithic reinforced concrete, 200 mm thick. The material of the above-ground load-bearing structures is concrete class B25, F75, working reinforcement of class A400C and steel C255. External walls - three-layer "sandwich" - panels 150 mm thick with fastening to the frame columns and half-timbered elements and monolithic reinforced concrete walls lined with a ventilation facade system. Structural solutions for fastening the ventilated facade system to the supporting structures of the building are developed in the working documentation in accordance with the current technical certificate of the Ministry of Regional Development of the Russian Federation. Ceilings and roofing in the multi-level parking zone - slabs of monolithic reinforced concrete 230 mm thick along the longitudinal beams, section 500x500 mm. Ceilings and sections of coatings in the area of ​​workshops and in the area of ​​office and administrative premises - beamless slabs of monolithic reinforced concrete with a thickness of 200 mm and 220 mm. Bearing structures of the roof in the area of ​​workshops in axes 15-17 / G-DD - truss trusses of spans of 18 m supported on reinforced concrete crossbars; coating - corrugated board on steel girders. Coatings and in axes 17-20 / F-DD - corrugated board on monolithic reinforced concrete beams. Covering in axes 1-12/A-D – sheeting on steel girders supported by steel frames. The floor slabs of the first floor are made of monolithic reinforced concrete B25, 220 mm thick along strip foundations and ribs, section 250x1200 (h) - 300x1700 (h) mm. Stair structures - from monolithic reinforced concrete (internal stairs) and metal (external evacuation). The calculation of load-bearing structures and foundations was performed using the SCAD 11.3 software package, taking into account the joint work of the building with the foundation. The required fire resistance of reinforced concrete load-bearing structures is confirmed by calculations. The foundations are taken on a natural basis, strip, from monolithic reinforced concrete B25, W8, F150, the thickness of the strips is 300 mm. The depth of foundations is below the freezing of soils. Under the foundation, concrete preparation is provided for a layer of sand and gravel mixture with a thickness of 200 mm. The relative mark of 0,00 corresponds to the absolute mark of 17.050. The basis of the foundations is the EGE-2 soil (semi-solid loams with interlayers of hard-plastic ones) with φ=14 degrees, e=0.31 kgf/cm2, E=11 MPa. The design resistance of the foundation soil is 370 kN/m2. The maximum draft of the building is 4 cm. Impact on the surrounding development is not expected. The project provides for pasting waterproofing of concrete structures in contact with the ground. The building of a one-story boiler house is designed in a steel braced frame. Building responsibility level - II. External walls and covering - three-layer "sandwich" - panels 100 mm thick. Spatial rigidity and stability of the boiler house building is provided by vertical and horizontal connections. The foundation for the boiler building is assumed to be shallow on a natural base in the form of a monolithic reinforced concrete slab 200 mm thick with ribs directed upwards 200 mm high and a pit 2.0 m deep. Concrete B15, W6, F75, class AIII reinforcement. Under the foundation, concrete preparation is provided with a thickness of 100 mm and a layer of crushed stone with a thickness of 200 mm. The project provides for the replacement of bulk soil and the installation of a sand cushion with layer-by-layer compaction 1.75 m thick. The projected chimney is a 20.0-meter-high truss-type lattice tower with two gas exhaust shafts. The load-bearing tower is a three-dimensional triangular vertical structure with the dimensions of the faces in the plan 1.2 m, consisting of steel pipes and lathing from bent box-section profiles. Steel C285. An anti-corrosion coating of the steel structures of the carrier tower is provided. Gas exhaust shafts - two pipes with a diameter of 350 mm made of alloy steel with thermal insulation. The gas exhaust shafts are attached to the supporting spatial structure with a step of 2,6 m. The chimney is designed as a cantilever with rigid fixation into the foundation by means of anchor bolts. The foundation of the chimney is on a natural foundation made of monolithic reinforced concrete, 2,45 m high, dimensions in terms of diameter 4.2 m. Concrete preparation 100 mm thick is provided under the foundation. Foundation material - class B15, F75, W6 concrete, class AIII reinforcement. Loads taken in the calculation of the foundation: М=16,8 t*m, N=3,0 t, Q=1,3 t. The basis of the foundations for the boiler house building and for the chimney is the IGE-2 soil (semi-solid loam with interlayers of hard-plastic) with φ=14 º, e=0.31 kgf/cm2, E=11 MPa. The design documentation provides for coating waterproofing of foundations and a pit. Calculations of the load-bearing structures of the boiler house building and the load-bearing structure of the chimney were performed using the SCAD 11.3 software package. The relative elevation of 0.00 corresponds to the absolute elevation of +17.05 m.
