The basement is designed with load-bearing outer walls 200 mm thick with external insulation with effective insulation 50 mm thick. The material of the outer walls of the basement is concrete of class B 25, W12, F100. The inner walls of the basement are 200 mm thick. The thickness of the walls of typical floors is 160 mm. Pylons - section 300 x 600 mm, 300 x 700 mm. Ceilings above the basement and above the first floor - monolithic reinforced concrete 200 mm thick, interfloor ceilings and roofing - 160 mm thick. The constructive solution of balconies and loggias is a slab monolithically connected with the ceiling. To prevent freezing in the ceilings, thermal inserts made of grade 35 foam are provided, the balcony sections of the slabs are designed from concrete of the frost resistance grade F100. The external load-bearing walls and pylons of the first floor are multi-layered, made of a layer of monolithic reinforced concrete 200 mm thick, a layer of mineral wool insulation 150 mm thick, and facing with self-supporting wall stone 120 mm thick. Enclosing external walls - non-bearing multi-layer, with floor-by-floor support on floors: the walls of the first floor are designed from expanded clay concrete 400 mm thick, grade D 650, B 2,5, F 50, on a thin-layer mortar M100, with a lining of self-supporting wall stone 120 mm thick, on solution M100, with an air gap of 30 mm. walls of typical floors - from expanded clay concrete 400 mm thick, grades D 650, B 2,5, F 50, on a thin-layer mortar M100, and thin-layer plaster on a grid. Fastening of the outer walls to the supporting structures of the building is provided by flexible stainless steel ties with anti-corrosion coating. To reduce thermal deformations of the masonry, horizontal (at the level of the bottom of the floor slab) and vertical - expansion joints are provided. The service life of the structures of the enclosing external walls is 50 years. Stairs - prefabricated reinforced concrete march - platforms. Elevator shafts - from prefabricated reinforced concrete bulk blocks. The spatial rigidity and stability of the building is ensured by the joint work of the transverse and longitudinal internal walls, united by horizontal disks of floors and roofs. The static calculation of the supporting structures of the building, taking into account the joint work of the building with the base, was performed using the SCAD 11.3 software package. Horizontal movement of the top of the building 4,7÷6,5 cm; acceleration of vibrations of the building structures, arising from the pulsation of the velocity pressure of the wind 0,021 ÷ 0,058 m/s2, which does not exceed the maximum permissible values. The main load-bearing structures of the building are designed to meet fire resistance requirements in accordance with STO 36554501-006-2006. The relative mark of 0,000 corresponds to the absolute mark of 3,900. The foundations of the residential building are piled. Piles - driven prefabricated reinforced concrete composite, section 35 x 35 cm, length 24 for sections 1÷5 and length 26 m for section 6, made of concrete class B 30, W8, F100. In accordance with the report on engineering and geological surveys, the lower ends of the piles are immersed in soils: EGE-10 - heavy silty loam with gravel, sandstone fragments, with gravel sand nests, gray-blue solid (E = 160 kgf / cm2, JL = - 0,19, e=0,600). The expected design draft of the sections is 4,0 cm. The calculated pile load of 120 tf was adopted on the basis of pre-design tests of piles with a static indentation load, carried out by Department No. 6 of OP "PKTI" in 2011, No. 7877. The project provides for control tests of 12 piles. Grillage - slab 600 mm thick from monolithic reinforced concrete, concrete class B25, W12, F100. Pairing of piles and grillage is rigid.

The parking lot is designed on an incomplete frame made of monolithic reinforced concrete, concrete class B25, F100. The car park building is divided by sedimentary seams into three parts. The columns of the car park frame are designed according to a grid of 5,05 - 6,4 x 5,55 - 6,4 m, with a section of 300 x 1200 mm, internal walls - with a section of 200÷300 mm. External walls - from monolithic reinforced concrete 250 mm thick, concrete B25, F100, W12. External load-bearing walls above ground level are designed as multi-layered - from a layer of monolithic reinforced concrete 250 mm thick, a layer of effective insulation 50 mm thick and a layer of wall stone cladding 120 mm thick. The operating coating is a monolithic reinforced concrete beamless slab with a thickness of 400 mm, the coating of the ground part is a monolithic reinforced concrete beamless slab with a thickness of 200 mm. The spatial rigidity and stability of the car park is ensured by the hard disk of the pavement, the rigid junctions of the columns with the pavement, and the pinching of the columns into the foundations. The foundations of the parking lot are taken on a natural basis in the form of monolithic reinforced concrete slabs 550 mm thick, made of concrete of class B 25, W12, F100.
