1. Main construction conditions

The project of organization of the object "" was executed on the basis of

• Engineering specification;

• report on the survey and assessment of the technical condition of the dormitory building No. 4;

• Design and estimate documentation ;

• building codes and regulations in force at the time of project release.

This section is developed taking into account the requirements of SNiP 12012004 "Construction Organization," "Recommendations on the methodology of PIC and PPM compilation," SNiP 12032001 part 1 and SNiP 12042002 part 2 "Labor Safety in Construction," SP "Decisions on Labor Safety and Industrial Safety in PIC and PPR"SanPiN 2.2.3.138403 "Hygienic Requirements for the Organization of Construction Production and Construction Works", MDS 1281.2007 "Methodological recommendations for the development of PIC and PPM," PPB 0103 "Fire Safety Rules in the Russian Federation," PB 1038200 "Rules for the Construction and Safe Operation of Lifting Cranes."

2. Brief description of the building

The renovated dormitory building is a detached, five-story stone, without a basement, rectangular in plan shape with overall dimensions in the axes of 77.2 × 15 m. The height of the building to the top of the cornice is 15.26 m.

The dormitory building was erected according to the standard project of the 13023 series "Student dormitory for 632 students for construction in areas with seismicity of 7 and 8 points," developed in 1959. The hostel was commissioned in 1966.

The structural scheme is a stone building with transverse and longitudinal bearing walls, united by disks of reinforced concrete floors rigid in their plane.

Foundations - tape, of prefabricated concrete blocks and reinforced concrete cushions according to the series II0302. Along the top of the foundations there is a monolithic reinforced concrete belt 150 mm high. The base of the foundations is presumably pebble soils with sand aggregate.

The external and internal walls are stone, designed from full clay brick on cement sand mortar. The thickness of the external walls is 640 mm, the internal longitudinal - 510 mm, the internal transverse - 380 mm. Monolithic reinforced concrete antiseismic belts are provided in the level of floors along all longitudinal and transverse walls.

Partitions - brick 120 mm thick.

Floors - made up of prefabricated reinforced concrete panels according to the catalog of the series JESUS 0302.

The stairs are two-march, composed of prefabricated reinforced concrete ribbed marches and platforms.

Floors in the corridors are mosaic, in toilets and washes - tiled, in classrooms and living rooms - plank with linoleum.

The roof is an attic four-pitched with small tongs on the waltzes. The height in the skate is 3.75 m, counting from the surface of the slabs of the attic floor. Roof of steel galvanized sheets, external drainage arranged.

External decoration - masonry made of full clay brick made with stitching, horizontal belts above window openings are made of silicate brick, end walls are faced with pressed fibrous-cement slabs "Kraspan."

Interior decoration. The surfaces of walls and partitions are plastered, painted or glued with wallpaper, ceilings are plastered and painted.

Engineering equipment. The building provides hot and cold water supply, central water heating, sewerage, power networks.

The level of responsibility of the building according to GOST 2775188 - II is normal.

Reliability factor by purpose - 0.95.

The overhaul project provides for the following measures:
