1.1 Description of local conditions

The project of the 12-storey 2-section 192quarter residential building is located at the address: Moscow Region, Elektrostal, developed on the basis of the customer's technical assignment.

The design of the building was developed for construction in the area with normal geological conditions 1B of subarea IIB of the climatic area with the following characteristics:

- humidity zone is normal;

- section relief is flat;

- snow area - III;

- design value of snow cover weight - 180 kgf/m2;

- wind area - I;

- standard value of wind pressure - 23 kgf/m2;

- weak activity of groundwater, normative depth of soil freezing - 1.13 m;

- groundwater opened at a depth of 2.2-2.7 m;

- geological conditions are optimal;

- the temperature of the coldest five-day period reaches 26 ° C (Table No. 1. SNiP 23012003);

- the air temperature (outside) of the coldest days reaches 34 ° C (Table No. 1. SNiP 23012003);

- dominant winds: in the winter season - western, and in the summer season - northeast.

The relative elevation ± 0.000 is the level of the clean floor of the first floor of the building.

Design Solutions

The structural diagram of the designed building has a arceless structure with longitudinal and transverse bearing walls, as well as diaphragms and stiffening discs (floor slabs). The main structural elements of the building are:

- foundations - reinforced concrete piles;

- walls - block and monolithic reinforced concrete;

- floors and covering - cast-in-situ reinforced concrete;

- partitions - block and monolithic;

- windows - plastic;

- doors - wooden;

- stairs - prefabricated reinforced concrete;

- roof - roll;

- floors - concrete, ceramic tiles, laminate, linoleum;

- other structures:

o pavement - asphalt;

o elevator shaft - monolithic reinforced concrete.

1.4.2 Walls

The external walls of the building are designed from blocks of cellular concrete "YTONG" with a thickness of 365mm, according to GOST 2152089 with monolithic reinforced concrete elements and insulation from mineral wool slabs "ROCKWOOL."

Outside, the walls are decorated with colored plaster, it looks massive and capital, giving the building tectonic expressiveness.

1.4.3 Floors and covering

Floors and coverings are designed from cast-in-situ reinforced concrete. The use of slabs and coatings made of monolithic reinforced concrete gives the freedom to give the facades and internal layout personality relatively easily. The roof is designed from a three-layer waterproofing carpet made of ruberoid and a protective 4cm layer of cement cloth bracing, which is 1.5 times less laborious than rolling attic roofs and 1015% cheaper than them.

1.4.4 Partitions

Partitions of the building are designed walls from blocks of cellular concrete "YTONG" with a thickness of 200mm, according to GOST 2152089 with monolithic reinforced concrete elements with finishing from gypsum boards with a thickness of 12.5mm, and plaster mortar. But the gypsum partitions are rather fragile and during transportation, storage and installation can collapse due to inept handling.

1.4.7 Roof

Roofing carpets made of guided materials shall be installed in accordance with SNiP 3.04.0187 "Insulation and Finishing Coatings" and "Recommendations for the Design and Construction of Roofs Using Roll Roofing Coating Materials."

1.4.9 Other structures

Blind area

Make asphalt pavement around the building with a slope of at least 3% from the building and a width of 900 mm. Perform paving according to prepared layer of expanded clay gravel (with density of 800 kg/m3) with thickness of 100 mm and width of 900 mm.

Elevator shaft

The shaft walls shall be made of concrete of class B20 in monolithic reinforced concrete. The deviation of the shaft walls from the vertical plane shall not exceed 15 mm. Permissible difference of shaft diagonals in the plan shall not exceed 25 mm. Installation flooring in the elevator shaft shall be installed prior to installation works. Clean floor shall be filled in 50 mm thick machine room after installation of elevator equipment. After installation of the elevator, work must be done to terminate holes for mounting flooring, holes in the area of ​ ​ the lower stop of the elevator.
