The roof is flat, ventilated combined. On the upper layer of insulation there are plates OLK30UPO of the company ISOVER with grooves 15x15mm, pitch 10mm, on the lower side of the plate, which form row ventilation channels. Air from the manifolds is discharged to the atmosphere through ventilation pipes with a diameter of 110 mm.

Access to the roof is carried out through the metal fire ladder Lp 1.

Floors - prefabricated reinforced concrete slabs.

Lintels - prefabricated reinforced concrete bars.

Staircase marches - prefabricated reinforced concrete.

Windows - wooden according to GOST 112142003.

Doors - wooden as per GOST 2469881 and GOST 662988, fire fighting as per series 1.2365, v.1.

Floors - linoleum, ceramic tiles, concrete and cement sand. The floor of the first floor is insulated with mineral wool slabs P 175 GOST 957396 b = 220 mm.

In the basement there is a storeroom of harvesting equipment. The basement floor has exits directly outside, not connected to exits from the first floor.

On the first floor there are rooms of the entrance group, exits of staircases. The entrances to the entrances of the building are oriented to the courtyard territory. On each floor there are three apartments. All apartments have premises (living rooms, bedrooms), kitchens, the separate and combined bathrooms, halls. In the apartments located on the second floor, balconies are designed. The time of solar insulation of residential premises meets the regulatory requirements. The electric panel room is located on the first floor in the axes "4" "5."

In the exterior decoration, red brick facing masonry and gray insert (OJSC Glubokinsky Silicate Brick Plant) were used. The basement is plastered with cement sand mortar along a metal mesh.

3.5. Brief description and justification of design solutions.

Design decisions in the working design are made in accordance with the design assignment.

Design decisions were made out of the need to ensure the unity of construction solutions, reduce material consumption, labor intensity and construction cost.
