The buildings are designed from products manufactured by CJSC DSK "BLOK". Basement structures - from monolithic reinforced concrete. Concrete B25, W6, F100, class A-III and A-I reinforcement. The outer walls of the basement are 380 and 480 mm thick, above the blind area - 200 mm thick with insulation and finished with Melikon-Polar concrete stone. The inner walls of the basement are 300 mm thick. Ceiling above the basement - slabs 200 mm thick. Non-bearing external walls - reinforced concrete hinged panels made of B15, F50 concrete 120 mm thick. Bearing external walls - reinforced concrete panels (concrete B22,5, F50) 160 mm thick / External walls - insulated with Rockwool slabs 150 mm thick and finished with the U-KON suspended facade system with porcelain stoneware slabs with an air gap device. Finishing of external walls in the area of ​​stairs - thin-walled plaster with coloring. The hinged ventilated facade system adopted in the project documentation must be developed in the working documentation and have the relevant valid technical certificate of the Ministry of Regional Development of the Russian Federation. Internal walls - prefabricated reinforced concrete panels (concrete B30) 200 mm thick, from the 9th floor and above - 160 mm thick (concrete B22,5). The step of the transverse walls is from 3,0 to 3,8 m. Partitions - prefabricated reinforced concrete panels (concrete B15), thickness 80 mm, made of bricks 120, 250 mm thick and tongue-and-groove slabs. The lintels are prefabricated reinforced concrete. Ceilings - prefabricated reinforced concrete flat slabs 160 mm thick, rigidly connected to balconies (concrete B15, B22,5). Balcony slabs made of concrete B22,5, F75, W2. Floor slabs of transitional balconies made of concrete B22,5, F150, W4. Fittings of all plates - A-III, BP-I, A-I. Bay slabs - prefabricated reinforced concrete ribbed beam-type slabs with a rib height of 250 mm supported on reinforced concrete consoles. The connection of floor slabs to each other - by welding, by welding connecting plates or reinforcing ties to the hinges or embedded parts of the slabs. Sealing of seams - cement-sand mortar M200. Loggias - with structural glazing, with fastening of load-bearing structures made of aluminum to floor slabs. Elevator shafts - prefabricated reinforced concrete volumetric blocks with a wall thickness of 120 mm. Ventilation blocks - prefabricated reinforced concrete three-dimensional blocks, with floor-by-floor support on floor slabs. Sanitary cabins - prefabricated reinforced concrete panels made of B25 concrete, 60 mm thick. Elements of stairs - prefabricated reinforced concrete marches and platforms made of concrete B25, F50. The horizontal joint of the load-bearing panels of the internal walls is platform, with the transfer of forces to the underlying panel through the floor slabs. The panels are mounted using vertical fixation elements (pin fixators) with the wall panel of the next floor (the pins were not taken into account in the shift calculation). Horizontal mortar joint - 20 mm thick, cement-sand mortar M200. The horizontal joint of the single-layer hinged panel of the outer walls is platform, with partial support on the floor slab (overhang - 30 mm). Horizontal mortar joint - 20 mm thick, cement-sand mortar M200 and M100. The vertical joint of the load-bearing panels of the internal walls - keyed joints and horizontal steel ties with the joints sealed with fine-grained concrete B22,5 and B15.

The dowels of the side faces of the panels are 55 mm deep. Vertical junction of non-load-bearing facade panels with panels of internal walls - with fastening of panels with horizontal steel ties that perceive the pull-off force. The fastening of all prefabricated structures to each other is carried out by welding the connecting elements (plates and rolling corners) to the embedded parts. Spatial rigidity and stability of building sections is ensured by the joint work of transverse and longitudinal walls in combination with floor disks. All prefabricated elements produced by CJSC DSK "BLOK" correspond to the loads of an individual residential building. Calculation of residential buildings was performed on the software package "Lira 9,6" by the method of equivalent replacements, taking into account: the pulsating component of the wind load; joint work of the above-ground part of the building and foundations. The maximum values ​​of mutual shifts between walls and ceilings in the platform joint are 0,7 mm. The maximum values ​​of mutual shifts between the walls of the perpendicular direction are 0,1 mm, which does not exceed the maximum allowable values. The level of responsibility of buildings is the second (normal). The service life of buildings is assumed to be at least 100 years. The structural scheme of the six-storey car parks is a frame one (buildings 7 and 9).

The walls of the stairs are made of hollow brick M150 with a thickness of 120 mm. Spatial rigidity and stability of the temperature blocks of car parks is provided by frame junctions of columns and beams of hard disks of monolithic floors. Each of the car parks (building 7 and building 9) is divided in width into two temperature blocks with floors at different levels, with one-sided movable support of the ramp beams on the floor beams of different temperature blocks. Between the car park buildings (7 and 9), building 8 is designed and separated from the car parks by expansion joints. The structural scheme of the two-story building 8 is frame-wall.

Racks - from steel rolling I-beams 20K1. The spatial rigidity and stability of the hull is ensured by the joint work of the reinforced concrete frame and load-bearing brick walls. The calculation of buildings 7, 8, 9 was performed using the Lira 9,6 software package by the method of equivalent replacements, taking into account the pulsating component of the wind load and the joint work of the above-ground part of the building and foundations. The level of responsibility of buildings is the second (normal). The service life of buildings is assumed to be at least 100 years. The mark of 0,000 is the floor mark of the first floor of residential buildings 1-6, corresponding to the absolute mark of 4.80, the floor mark of buildings 7-9 is 3.65. The foundations were developed on the basis of engineering and geological surveys carried out at the construction site. The foundations of the buildings are piled.
