- obtaining of normal coefficient of development at fulfillment of sanitary and fire safety standards.

This project provides for the placement of the following utility sites:

- site for waste collectors;

- site for carpet knocking out;

- linen drying area;

- playground;

- two sites for personal transport.

Vertical layout of the site is solved by the method of design elevations taking into account natural conditions, construction requirements, conditions of organization of surface water runoff. The main factors that determined the high-altitude solutions of the site are the terrain, the conditions for the organization of drainage, the existing development. Surface water removal from the site is designed taking into account runoff in the trays of the roadway of the on-site driveways with subsequent discharge to the relief. The design slope is 0.3%.

To ensure normal sanitary and hygienic conditions on the site of a residential building, improvement and landscaping measures are provided:

- Areas free from development and coverage are landscaped and landscaped;

The structural diagram of the building is a arceless building, with transverse load-bearing walls connected by floor reinforced concrete floor panels. Foundations of precast reinforced concrete and concrete blocks. External walls of three-layer reinforced concrete panels. Floor and covering of prefabricated reinforced concrete panels with thickness of 160mm size per room. All apartments have loggia. A basement is provided in the house, where premises for housekeeping are previously located. In all apartments the entrances to the premises are isolated.

Building capital - Grade II; fire resistance - grade II; durability degree - II.

The residential building is solved by a 7-story 2-section with a basement.

The building in the plan has a complex shape due to the protruding and declining loggia. The dimensions of the building are 51.2x12m. Floor height 2.8m. Basement height 1.98 m.

Number of apartments 56, on floor 8, 4 in each section.

1.3 Architectural and Structural Solution

1.3.1 Architectural Solutions

The exterior of a multi-storey residential building is closely related to its internal layout, structures, materials and construction methods.

The decisive influence on the appearance is made by multi-family, a combination in one volume of a large number of repeating apartments. This combination creates a kind of mesh construction of the facade.

In this 7-story building, the details of the facade - the grouping of windows of various sizes, loggia, decoration elements determine the rhythmic construction of the facade, betraying the house with a characteristic appearance.

The solution for the exterior decoration of the building: three-layer panels with a textured layer - are provided taking into account the color and textures of the existing development of the microdistrict.

When designing the structure, the reliability factor is adopted.

The structural diagram of the house is a system of mutually perpendicular reinforced concrete walls. The floor is supported in the outline of the room. To ensure spatial rigidity of the building and reduce deformations, the project developed a set of measures aimed at engineering preparation of the base and increasing the rigidity of the building. Prefabricated reinforced concrete items are accepted according to TK201 catalog. 5984. Base preparation is made by layer of crushed stone (50 mm). The foundations are designed prefabricated, reinforced concrete, in the form of cross belts with monolithic sections made of heavy concrete B15 on Portland cement according to GOST 1017876 with mineral additives with coating waterproofing with bitumen in 2 passes. Basement walls are made of prefabricated concrete blocks as per GOST 1357978 .

During the construction of the underground part of the building, the following measures are provided: organization of cavities for the commissioning of communications and the organization of a heat station.

External and internal walls are made of three-layer wall panels.

Partitions are accepted from small-sized gypsum plates as per GOST 64. 2883, bathrooms from volumetric blocks.

Slabs of continuous cross-section for a room with a thickness of 160 mm according to the 1.141-13 series. 60, 64. Stairs prefabricated reinforced concrete platforms according to series 1. 151. 1-3 marches in series 1. 131. 1-6.

Loggias are designed from standard and individual reinforced concrete structures.

The openings of the building are filled with window blocks, balcony and entrance doors blocks. The ends of all carpentry products are antiseptic with antiperene, hydroinsulated with bitumen mastic and law-abiding with packs.

1.4.1 exterior decoration of the building

The exterior decoration of the buildings is designed in accordance with the current standards, taking into account local materials, construction capabilities, linkage with the surrounding development and protection of the surrounding structures from atmospheric impacts.

The decoration of the facades is adopted as follows - embossing and embossing of seams, installation of decorative plastic fences of balconies and loggias. The basement and corners of the walls are faced with wild stone. Door bindings are painted with enamel paint.
