All floors shall be made on wooden beams of 150x150 mm bar (spacing 1000... 1200 mm) with laying between them as sounds and heat insulation of mineral wool plates URSA (s = 100... 150 mm).

Rafter roof structures shall be made of sawn softwood.

Roof coating - galvanized roofing steel.

Floors - plank on lags.

Windows - as per GOST 1121486.

Doors: external - metal, internal - wooden.

4 finishing works

All walls of the building on the outside are treated with wood antiseptic under the color of light nut.

Paint window and wooden door blocks with enamels of light tones.

Internal finishing of ceilings shall be made with water-emulsion compositions.

When performing finishing works on the escape route, it is necessary to pay attention to the fire characteristics of the materials and ensure their compliance with the requirements of paragraph 6.25 of SNiP 210197 *.

5 protection of structures against corrosion, rotting and fire

All wooden elements in contact with concrete are laid on two layers of ruberoid.

According to SNiP 3.04.0385, the surfaces of wooden elements are antisepted with an aqueous solution of the preparation BBX3 (composition: technical borax - 61%, boric acid - 39%) of 10% concentration .

Treatment with antiseptics is carried out after mechanical treatment at wood moisture content of not more than 25 %.

The surfaces should be treated by spraying in 2 times, the interval between the 1st and 2nd treatment should be at least two hours at an air temperature of 180-200 C. In winter, the solution should be heated to 400-500 C, and the wood should be treated at a temperature of at least 100 C. In case of violation of the protective coating, the layer should be restored.

6 Construction Supervision

During construction and installation works it is necessary to strictly observe the requirements of the following regulatory documents: SNiP 3.01.0185 *; SNiP 3.02.0187; SNiP 3.03.0187; SNiP 3.04.0187; SNiP 3.05.1085; SNiP 3.05.0385; SNiP 3.05.0485 * and other requirements of state norms, standards and working documentation.

Before the start of excavation, call on the site representatives of organizations operating engineering networks and communications in the construction area.

During performance of works it is necessary to ensure strict control (with preparation of certificates of inspection of hidden works) of compliance to the project of all construction and installation works performed.

All equipment, products and materials must be certified and have Gosstandart permission for use in the Russian Federation.

7 Winter Instructions

The works shall be performed in accordance with the work execution project and SNiP 3.02.0187, SNiP 3.03.0187, SNiP 3.04.0187, SNiP 3.04.0385, SNiP 2.03.1185, SNI2281, SN 29074.
