Architectural and space-planning solutions

 The design documentation provides for the construction of a residential complex designed on a territory free from development. The residential complex consists of 3 multi-apartment residential buildings (hereinafter referred to as residential buildings), which form an open courtyard space. The entrances to the buildings are designed from the side of the courtyard. Residential building 1 - a detached building of 3 sections with 5 above-ground floors, including an attic floor, with an underground technical underground, without an attic, with a roof gas boiler room. The residential building has an L-shaped broken outline in plan with dimensions in the extreme axes (14,05 + 38,28) x (31,14 + 14,1) m. Residential building 2 is a separate building of 4 sections with 5 above-ground floors , including the attic floor, with an underground technical underground, without an attic, with a roof gas boiler room. The residential building has an L-shaped broken outline in plan with dimensions in the extreme axes (60,17 + 14,06) x (31,13 + 14,11) m. Residential building 3 is a separate building of 4 sections with 5 above-ground floors , including the attic floor, with an underground technical underground, without an attic, with a roof gas boiler room. The residential building has an L-shaped broken outline in plan with dimensions in the extreme axes (60,17 + 14,06) x (31,13 + 14,11) m. In each residential building, the height of the technical underground premises is designed to be 1,80 m. The height of the premises of typical residential floors is 2,74 m (with a floor height of 3,0 m). The height of the attic floor rooms to the bottom of the cover is variable, from 3,17 m to 4,475 m. The height of the roof boiler room to the bottom of the cover is variable, from 2,40 m to 2,90 m. The level of the finished floor of the first floor is taken as a relative mark of 0,000. The greatest height of the vertical plane of the facade from the planning ground level (-1,05 m) to the top of the crowning cornice of the building is 16,00 meters. The height from the planning mark of the ground to the ridge of the building is 18,00 meters. The height from the planning mark of the ground to the ridge of the roof boiler room is 19,47 meters. In each residential building, the technical underground is designed under the entire building, divided into sections and it provides for the wiring of engineering communications, the premises of the ITP, the water metering unit, and the switchboard are designed. Technical undergrounds have independent entrances and exits. On all overlying floors residential premises - apartments are designed. For evacuation and communication between floors in each section of each residential building, a staircase of the L1 type was designed. Access to the roof is provided through metal vertical fire escapes at the ends of the buildings. In sections where roof boiler rooms are designed, access to the roof is from the stairwell. On the height differences of the roof, the installation of metal fire escapes is provided. In each section of each residential building, a passenger elevator with a carrying capacity of 675 kg is designed. The types and number of apartments in residential buildings are accepted in accordance with the apartment layout agreed by the customer. The walls of the technical underground up to the planning ground level are monolithic reinforced concrete, with thermal insulation from extruded polystyrene foam slabs, higher up to the level of 0,000 - monolithic reinforced concrete with thermal insulation from extruded polystyrene foam slabs with a finishing layer of thin-layer plaster with high-strength additives. External load-bearing walls - monolithic reinforced concrete with thermal insulation from mineral wool boards and with a finishing layer of thin-layer plaster. External non-bearing walls - from porous stone with floor-by-floor support on floors, with thermal insulation from mineral wool boards and with a finishing layer of thin-layer plaster. The masonry of the outer walls at the level of the parapet is made of solid brick. Internal load-bearing walls - monolithic reinforced concrete. Partitions - from tongue-and-groove gypsum blocks: single-layer, two-layer - with an air gap through the insulation; from a brick - in technical rooms. Windows and balcony doors - metal-plastic with double-glazed windows, with built-in air inlets. Glazing of balconies and loggias - stained glass system with single glazing. Doors - metal and wooden, glazed and deaf, fire-resistant and conventional. Covering (roof) - gable, flat, combined, with a roof made of metal sheets. Drainage - external organized. In the decoration and details of the facades, a colored decorative Turkish piece of light brown, dark brown and light beige colors is used. The basement is finished with colored decorative dark gray plaster with the addition of stone chips. The premises of the residential floors are designed with finishing and equipment. The interior decoration of the premises and the flooring are designed in accordance with the purpose of the premises: floors - cement-concrete with an epoxy water-emulsifiable coating, with a ceramic tile coating, a carpet of a parquet board, TZI linoleum; walls - with grout or plaster, followed by coating with alkyd paints, ceramic tiles, wallpaper; ceilings - with water-dispersed or adhesive coloring. Roof boiler rooms are designed in monolithic reinforced concrete structures.

Structural and space-planning solutions

 Residential buildings of the complex are designed in monolithic reinforced concrete structures in a cross-wall structural system and are divided by expansion joints into temperature blocks. Wall pitch - from 3,2 m to 4,8 m. Walls - 140 mm thick; 160 mm. Floor slabs and coatings - 160 mm thick. Spatial rigidity and stability of buildings is provided by a system of longitudinal and transverse walls connected by floor disks. The material of above-ground structures is concrete of class B25; F150 (floor slabs and coatings). External walls: non-bearing - floor-by-floor cut based on ceilings and consisting of porous stone 250 mm thick with insulation, load-bearing - monolithic reinforced concrete with insulation, walls of the underground technical underground - monolithic reinforced concrete 250 mm thick with insulation. The calculation of the main load-bearing structures of residential buildings has been completed. The level of responsibility is normal. The foundations of residential buildings are monolithic reinforced concrete slabs 350 mm thick. The base of the foundations is semi-solid silty loam, with gravel and pebbles, with design characteristics ρ=2,07 t/m3, φ= 22°, c=0,39 kgf/cm2, E=130 kgf/cm2. The expected design settlement of buildings is 5 cm. The material of underground structures is B25 class concrete; W8; F150; fittings class 400C. Waterproofing of the technical underground from groundwater: the use of high-grade concrete for water resistance for the foundation slab and external walls, the use of waterproofing pads in the working seams of concreting. The relative mark of 0,000 corresponds to the absolute mark: residential building 1 - 53.90; residential buildings 2; 3 - 54.10.
