Architectural planning and space-spatial solutions.

The relief of the site is calm with an average elevation of 3.60. The designed residential building is considered as a single volume with three stairwells, has a U-shaped configuration in plan, 103 m long and consists of an underground parking garage, a ground floor with office space and a 4-storey residential group. The main element of the complex is a round 5-storey part, which is the compositional center of the projected complex. In the courtyard part of the residential building there is an exploited roof located above the underground parking lots. The mark of the operated roof is 1.2 meters above ground level. The parking lot unites the residential building into a single volume, creating the feeling that the entire complex stands on a single platform raised above the ground. Playgrounds, recreation grounds, sports grounds are located in the nearby territories of the quarter due to the tightness of the design site. Vehicle entry to the operated roof is not provided. For pedestrian connection with the ground level, stair descents and a ramp for MGN were designed. On the north side of the residential building is the main road. At the entrance to each main entrance there is a spacious hall with access control, as well as concierge rooms with bathrooms and pram rooms. The entrance to the garage of residents is carried out along the entrance ramp from the side of the driveways, separately from the entrances to the housing. From garages to residential buildings, you can go through the vestibule-gates to the combined lobbies of the first floor, and to the evacuation stairs leading to the roof in operation. Relative elevation ±0.000 (1st floor) corresponds to absolute elevation 5.00. 64 apartments are designed in the building, having from 1 to 3 rooms of various sizes. The architectural and planning solution is dictated by the nature of the existing building and the design task. The space-planning solution made it possible to maximize the use of the area of ​​the plot allocated for construction.

facade solution. Exterior finish.

The solution of the facades is determined by the style of the existing development of the avenue and the space-planning solution. The main articulations and elements of the facades are highlighted with a color solution using continuous glazing elements. The cladding of the walls of the building is made of natural granite (or similar), the remaining floors of the residential part are painted putty on the grid and on the insulation. The use of facade glazing elements gives the building a modern look. Windows, balcony doors and facade glazing - metal-plastic with energy-saving double-glazed windows.

Materials and designs. Constructive decisions.

Constructive decisions

The relative elevation of the finished floor of the first floor of 0.000 corresponds to the absolute elevation of +5.000 m. The load-bearing frame of the building is a monolithic reinforced concrete (B25 concrete), consisting of disks of floors and roofing (mm thick), columns (section mm), beams (section mm), diaphragms ( mm thick). Fittings of class A400 (main) and A240 (transverse) Apertures are evenly distributed along the perimeter of the building. Spatial rigidity and stability are ensured by rigid coupling of diaphragms with ceilings and grillage, as well as monolithic stairwells and elevator shafts. The technical report on engineering and geological surveys for the development of the project for the construction of the agricultural market has been completed. The maximum groundwater level should be expected at a depth of 1.0-1.6 m per abs. marks 3.0-2.4 m. According to the results of chemical analyzes (based on the "Technical report on engineering and geological surveys ...", groundwater in accordance with SNiP 2.03.11-85 is non-aggressive in all respects to concrete and reinforced concrete structures. In this regard. In accordance with GOST 9.602-2005, groundwater has a high degree of corrosiveness in relation to lead and aluminum cable sheaths. Paint waterproofing of the basement walls is provided with rubber-bitumen mastic, which prevents the formation of dampness. The normative depth of soil freezing is assumed to be 1.27 m in accordance with SNiP 2.02.01-83* "Foundations of buildings and structures" Exterior walls: - three-layer, from the inside - reinforced concrete of the supporting frame t = 250 mm, thermal insulation layer (hard mineral wool board) 150 mm thick, air gap 50 mm, curtain wall "Alucobond". - three-layer, from the inside - aerated concrete blocks (D 600 B3.5) t = 250 mm, a layer of thermal insulation (hard mineral wool slab) 150 mm thick, an air gap of 50 mm, a hinged facade "Alucobond". - panoramic structural glazing. Galvanized rectangular profiles with a casing made of rigid PVC and glass-supporting profiles of the Schuco facade system are provided as the supporting frame of structural glazing. The Alucobond curtain wall is fastened to a galvanized frame made of brackets and profiles, which is attached to the outer walls. The wind load is transferred from the facing material through brackets and profiles to the outer wall. The insulation is fixed on the outer surface of the wall with dowels and special profiles. Partitions are made of aerated concrete blocks (D 400 B1.5). Elevator and ventilation shafts are made of monolithic reinforced concrete with a wall thickness of 250 mm. The expected settlement of the building is 5-7 mm, the uneven settlement is 2-3 mm, the displacement of the top of the building along the X axis is 3 mm along the Y axis is 6 mm, the building stability factor as a whole is more than 2.0. As part of the overall calculation, a calculation was made of the stability of the building against progressive collapse during local destruction of the building. One of the load-bearing columns was taken as a suddenly removed element of the design scheme. Based on the results of the analysis of this calculation, a decision was made to locally strengthen the elements that fell into the number of non-working ones after local destruction.
