Storage of structures, cladding panels and parts in the warehouse is carried out in packaged form on wooden beams up to 10 cm thick, in increments of 0.5 m. The warehouse must be closed, dry, with a hard floor covering.
Storing the structures, panels and parts specified in this paragraph in open areas and together with aggressive chemical products is not allowed.
3.9. When storing structures, they should be sorted by brand and laid taking into account the order of installation.
3.10. It is prohibited to move any structures by dragging.
3.11. To ensure the safety of wooden structures during transportation and storage, inventory devices (cradles, clamps, containers, soft slings) should be used with the installation of soft gaskets and linings in places where the structures support and come into contact with metal parts. Structures should be stored under a canopy to protect them from exposure to solar radiation, alternate wetting and drying.
3.12. Prefabricated structures should be installed, as a rule, from vehicles or enlargement stands.

The structures should be lifted in two steps: first to a height of 20 - 30 cm, then, after checking the reliability of the sling, further lifting is carried out.
3.16. When installing mounting elements, the following must be provided:
stability and immutability of their position at all stages of installation;
safety of work;
accuracy of their position using constant geodetic control;
strength of installation connections.

Structures that have special mortgages or other fixing devices should be installed using these devices.
3.18. The installed mounting elements must be securely fastened before unfastening.

In the absence of special requirements in the working drawings, maximum deviations in the alignment of landmarks (edges or marks) when installing prefabricated elements, as well as deviations from the design position of completed installation (construction) structures should not exceed the values ​​​​given in the relevant sections of this set of rules.
Deviations for the installation of mounting elements, the position of which may change during their constant fastening and loading with subsequent structures, must be assigned in the PPR in such a way that they do not exceed the limit values ​​after completion of all installation work. If there are no special instructions in the PPR, the deviation of elements during installation should not exceed 0.4 of the maximum deviation for acceptance.
3.21. The use of installed structures for attaching cargo pulleys, pulley blocks and other load-lifting devices to them is allowed only in cases provided for by the PPR and, if necessary, agreed upon with the organization that made the working drawings of the structures.
3.22. Installation of building structures (structures) should, as a rule, begin with a spatially stable part: a bond cell, a stiffening core, etc.
Installation of structures of buildings and structures of great length or height should be carried out in spatially stable sections (spans, tiers, floors, temperature blocks, etc.).
3.23. Production quality control of construction and installation works should be carried out in accordance with SP 48.13330.
The following documentation must be presented during acceptance inspection:
as-built drawings with introduced (if any) deviations made by the manufacturer of the structures, as well as the installation organization, agreed upon with the design organizations - developers of the drawings, and documents on their approval;

Requirements for surface quality and appearance of monolithic concrete and reinforced concrete structures

To assess the surface quality of monolithic concrete and reinforced concrete structures, four classes are used, determined by the maximum tolerances for straightness and local irregularities given in Table X.1. The classes apply to floors, walls, columns, foundations and other structures with straight surfaces. The main purpose of concrete surfaces is given in Table X.2. The class of the concrete surface of monolithic structures and the quality of concrete surfaces with special requirements for appearance must be specified in the design documentation. In unspecified cases, the surface class is assumed to be A6 or A7 (depending on the purpose).

Concrete surface classes

Table X.2. Appendix X. SP 70.13330.2012

The main purpose of concrete surfaces of monolithic structures

The design documentation must specify additional requirements for concrete surfaces that are constantly exposed to moving water or other aggressive influences.

Requirements for curved curved surfaces must be specified separately in the design documentation.

The following are not allowed on concrete surfaces:

• areas of uncompacted concrete;
• grease stains and rust stains (except for class A7 surfaces);
• exposure of reinforcement, except for working outlets of reinforcement and mounting fasteners of formwork;
• exposure of steel embedded products without anti-corrosion treatment;
• cracks with an opening width specified by the design organization (recommended value 0.1 mm for structures without protection from precipitation, 0.2 mm - indoors);
• sinks, chipped concrete ribs for class surfaces:
  • A3 - shells with a diameter of more than 4 mm, a depth of more than 2 mm, chipped ribs with a depth of 5 mm, a total length of more than 50 mm per 1 m of the ribs;
  • A4 - shells with a diameter of more than 10 mm, a depth of more than 2 mm, chipped ribs with a depth of 5 m, a total length of more than 50 mm per 1 m of the ribs;
  • A6 - shells with a diameter of more than 15 mm, a depth of more than 5 mm, chipped edges with a depth of 10 mm, a total length of more than 100 mm per 1 m of the edge;
  • A7 - shells with a diameter of more than 20 mm and chips of ribs with a depth of more than 20 mm, the length of the chips is not regulated.

Local irregularities (bulges, protrusions or depressions), the dimensions of which exceed the tolerances for surface classes according to Table C.1 with a measured distance of 0.1 m. For surfaces of class A3, bulges and protrusions are not allowed.

On concrete surfaces the following are allowed:

• for wall structures - holes for tie rods with plastic protective tubes of the tie rods left in them, holes for anchors (sealing of holes must be specified in the design documentation or PPR separately);
• imprints of panels and formwork elements;
• exposure of reinforcement clamps;
• for the lower surface of the floors - imprints of panels and deck elements, fastening elements for plastic structures, electrical wiring, etc.

To meet the requirements for concrete surfaces of classes A3 and A4, it is recommended to grind local projections and grout local depressions to achieve the required performance.

Before sending an electronic appeal to the Ministry of Construction of Russia, please read the rules of operation of this interactive service set out below.

1. Electronic applications within the sphere of competence of the Ministry of Construction of Russia, filled out in accordance with the attached form, are accepted for consideration.

2. An electronic appeal may contain a statement, complaint, proposal or request.

3. Electronic appeals sent through the official Internet portal of the Ministry of Construction of Russia are submitted for consideration to the department for working with citizens' appeals. The Ministry ensures objective, comprehensive and timely consideration of applications. Review of electronic appeals is free of charge.

4. In accordance with Federal Law No. 59-FZ of May 2, 2006 “On the procedure for considering appeals from citizens of the Russian Federation,” electronic appeals are registered within three days and sent, depending on the content, to the structural divisions of the Ministry. The appeal is considered within 30 days from the date of registration. An electronic appeal containing issues the solution of which is not within the competence of the Ministry of Construction of Russia is sent within seven days from the date of registration to the relevant body or the relevant official whose competence includes resolving the issues raised in the appeal, with notification of this to the citizen who sent the appeal.

5. Electronic appeal is not considered if:
- absence of the applicant’s surname and name;
