The spatial rigidity and stability of the building in the axes "ZH-M" is provided by the box-shaped structure of the basement, the rigid connection of the columns with the basement structures, the rigidity of the columns united by the disks of the built-in ceilings. Calculations of building structures were performed using a certified software package about the program "SCAD" v.11.5, "Fundation" in a finite element model. The level of responsibility of the building is the second (normal). The estimated service life of the building is assumed to be at least 50 years. The mark of the floor of the first floor, corresponding to the absolute mark of 0,000, was taken as 7.65. The foundations were developed in accordance with the results of engineering and geological surveys. The foundations are piled. Piles - bored, made from the surface of the earth using the CFA auger technology with partial excavation, 450 mm in diameter, 6,15 to 11,75 m long from the bottom of the grillages. Piles - from concrete B25, W6, F150 with reinforcement for the entire length with reinforcement A400 and A240. The absolute mark of the bottom of the piles is taken in accordance with the occurrence of the roof of the bearing layer of soil - minus 2.15, minus 2.60, minus 4.95. Based on the results of soil tests with piles, the design load on piles is assumed to be 55 tf. The base of the piles is silty plastic sandy loam (IGE6) with e = 0,55, E = 10 MPa, φII = 16°, IL = - 0,44, silty sands of medium density (IGE7) with e = 0,65, E = 18 MPa, φII = 30°, silty dense sands (IGE7.1) with e = 0,50, E = 34 MPa, φII = 35°, silty plastic sandy loams (IGE8) with e = 0,475, E = 10 MPa, φII = 18°, IL=-0,33.

Power plate of the floor: in the axes "А-Е" - 200 mm thick, in the axes "Ж-М" - 300 mm thick. Concrete B25, W6, F100, reinforcement A400. To prevent freezing, the foundations and the construction of the blind area along the perimeter of the building are insulated with a layer of foam plastic 50 mm thick. Preparation under grillages - from a layer of monolithic concrete B10 100 mm thick over a layer of crushed stone 200 mm thick. Preparation for the power plate of the floor - from a layer of medium-sized sand 200 mm thick. The maximum level of groundwater of the “perch water” type is possible at the surface of the earth.
