Architectural and space-planning solutions

The multi-apartment residential building is designed to be divided into three buildings - building 1 (western), building 2 (northern), and building 3 (eastern). Between the buildings, under the yard area, an underground parking lot has been designed. Buildings 1 and 2 from the second to the sixth floors are interconnected by the volume of unheated glazed verandas with a passage between the buildings at the level of the first floor. The dimensions of the building 1 in the axes are 17,6 x 40,9 m (maximum). The height from ground level to the top of the parapet in the 4-storey part is 14,0 m, in the 6-storey part - 19,5 m. The dimensions of the four-six-story building 2 in the axes are 16,4 x 41,2 m. The heights are similar to building 1. The dimensions of the four-story building 3 in the axes are 18,4 x 36,4 m. The height is 13,3 m. Sections of buildings are designed with a shift of the outer longitudinal walls relative to each other by 1,2 m in buildings 1 and 2 and by 2,0 m in building 3. Entrances to residential sections - from the level of the operated roof of the car park. Entrances to the built-in premises in the basement floors of buildings 1 and 2 - from the level of a pit 2,0 m wide running along most of the street facade of building 1 and the entire street facade of building 2. Entrance to the parking lot - in the southern part of the site using a ramp in front of building 3. In the volume of building 3, an elevator is provided to get to the floor level of the parking lot. The basement floor of building 3 provides storage rooms for residents with entrances in the end parts of the building, as well as in the southern half of building 1. The rest of the basement floor of building 1 provides built-in store, office and control room. The basement floor of building 2 will house a shop and three offices. Residential apartments are designed in all buildings from the 1st to the last floor. In the 6-storey sections of buildings 1 and 2, elevators with a carrying capacity of 1000 kg are designed. Stairwells of all buildings - type L1, without garbage chutes. Finishing of the walls of stairwells and non-apartment corridors - front brick with jointing, floors - ceramic tiles. Residential and built-in premises are rented without fine finishing. Glazed loggias are designed in the apartments above the 2nd floor. Balcony railings - aluminum profiles with single glazing. Window fillings - metal-plastic profiles with double-glazed windows. At the level of the 5th floor, at the height difference, in buildings 1 and 2, four verandas with single glazing are designed. The outer walls of the buildings are effective brick with face brick cladding in two colors. Plinth - facing with concrete tiles. The cover is flat. Roof - combined, rolled with internal gutters. The height of the roof railing is 1,2 m. The entrance-exit to the underground car park for 50 cars is designed on a single-track covered ramp with a slope of 18%. The structure of the parking lot includes a security room, a lift for the disabled, a storeroom for fire extinguishing equipment, and a storeroom for cleaning equipment. The project documentation provides for measures to ensure the life of the MGN and the disabled, including ramps to the level of entrances to the basement floors, ramps to the porches of entrances to housing, lifts on the first flights of staircases of residential sections.

Structural and space-planning solutions

Building responsibility level – II (normal). The project provides for the construction of a residential building, consisting of three buildings and an underground parking lot. Sedimentary joints are provided between buildings 1 and 2 and between all buildings and the parking lot. The structural system of residential buildings of the building is cross-walled with a step of transverse walls from 3,0 to 7,3 m. External walls - load-bearing two-layer, made of ceramic stone M150, F50 510 mm thick and front brick M150, F50 120 mm thick. The ligation of the lining with the masonry is provided through four rows of masonry. Internal walls - from hollow ceramic bricks M125, F50 380 mm thick. In the area of ​​ventilation ducts and chimneys - from solid clay bricks M150, F50. The outer walls of the basement floor are made of monolithic reinforced concrete class B20, F100, W6, 380 mm thick with foam insulation 100 mm thick and external cladding. Internal walls - from monolithic reinforced concrete class B20, F100, W6, 380mm thick. Ceilings and coverings - from prefabricated reinforced concrete multi-hollow panels with a thickness of 220 mm. Loggia ceilings - monolithic reinforced concrete of B20, F75 class concrete, 180 mm thick. Terrace ceilings are designed from precast concrete floors on prefabricated reinforced concrete beams. Elevator shafts - prefabricated reinforced concrete 110 mm thick. Stairs - prefabricated reinforced concrete marches and platforms. The spatial rigidity and stability of the building is ensured by the joint work of vertical elements united by floor hard disks. The load-bearing structures were calculated using the SCAD software package version 11.1. The relative mark of 0.000 is taken as the absolute mark of 33,10. The foundations of residential buildings are taken on a natural basis, in the form of monolithic reinforced concrete slabs 450 mm thick, concrete B20, W4, F75. In accordance with the report on engineering and geological surveys, the base of the foundation is EGE-2 soils, dusty yellowish-gray sands of medium density saturated with water with characteristics φ=26º, e=0,748, E=110 kg/cm2i EGE-6, silty gray sands of medium density saturated with water with characteristics φ=32º, e=0,608, E=240 kg/cm2. The calculated resistance of the base soil is 1,2 kgf / cm2, the average pressure under the sole is 1,0 kgf / cm2, the expected draft is 8,0 cm. The car park is a recessed structure with an incomplete frame made of monolithic reinforced concrete of class B20, F100, W6 and with an exploitable roof. Frame columns are designed according to an irregular grid from 4,9 to 7,9 m. The exploited coating is a monolithic reinforced concrete slab 300 mm thick on monolithic reinforced concrete beams with a section of 400 x 600÷870 mm. The spatial rigidity and stability of the car park is ensured by the joint work of the vertical elements, united by the hard disk of the cover and by pinching the columns into the foundations. The foundations of the car park are on a natural base, in the form of a monolithic reinforced concrete slab 500 mm thick, concrete B20, W6, F100. The basis of the foundation is the EGE-6 soils, medium-density silty gray sands saturated with water with the characteristics φ=32º, e=0,608, E=240 kg/cm2 5, E=22 kg/cm0,28). The calculated resistance of the base soil is 1,4 kgf / cm2, the average pressure under the sole is 0,5 kgf / cm2, the expected draft is 3,0 cm. Under the foundations, concrete preparation is provided from concrete of class B7,5 with a thickness of 100 mm. The project provides for the simultaneous construction of the foundations of a residential building and a parking lot. The device for blocking the underground parking lot is made after the construction of the above-ground part of the residential buildings. The project provides for vertical waterproofing of structures in contact with the ground, from Woltex geotextile mats, and horizontal waterproofing along the edge of foundations. The existing development (residential building and school) is located at a distance of more than 25 m. No impact on the surrounding development is expected.
