Requirements for surface quality and appearance of monolithic concrete and reinforced concrete structures
To assess the quality of the surface 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 concrete surface class of monolithic structures and the quality of concrete surfaces with special requirements for appearance should be specified in the project documentation. In unspecified cases, the surface class is accepted as A6 or A7 (depending on the purpose).

The project documentation should specify additional requirements for concrete surfaces that are constantly exposed to moving water or other aggressive influences.
Requirements for curved curved surfaces should be specified in the design documentation separately.
On concrete surfaces are not allowed:
- 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 the formwork;
- exposure of steel embedded products without anti-corrosion treatment;

- sinks, chipped concrete ribs for surface class:
- A3 - shells with a diameter of more than 4 mm, a depth of more than 2 mm, chips of a rib 5 mm deep, a total length of more than 50 mm per 1 m of the rib;
- A4 - shells with a diameter of more than 10 mm, a depth of more than 2 mm, chips of a rib 5 m deep, a total length of more than 50 mm per 1 m of the rib;
- A6 - shells with a diameter of more than 15 mm, a depth of more than 5 mm, chips of a rib 10 mm deep, a total length of more than 100 mm per 1 m of the rib;
- A7 - shells with a diameter of more than 20 mm and chipped ribs with a depth of more than 20 mm, the length of the chips is not regulated.
Local irregularities (beads, protrusions or depressions), the dimensions of which exceed the tolerances for surface classes according to Table C.1 at a measured distance of 0.1 m. For surfaces of class A3, nodules and protrusions are not allowed.
On concrete surfaces are allowed:
- for wall structures - holes for tie rods with plastic protective tubes of the tie left in them, holes for anchors (sealing of holes should be specified in the project documentation or PPR separately);
- imprints of boards and formwork elements;
- exposure of reinforcing clamps;
- for the lower surface of the floors - imprints of boards and deck elements, fastening elements of plastic structures, electrical wiring, etc.
To meet the requirements for concrete surfaces of classes A3 and A4, grinding of local protrusions and grouting of local depressions is recommended to achieve the required performance.

The quality of construction and installation works must be ensured by the current control of the technological processes of preparatory and main works, as well as during the acceptance of works. According to the results of the current control of technological processes, certificates of examination of hidden works are drawn up.
3.6 Structures, products and materials used in the construction of concrete, reinforced concrete, steel, wood and stone structures must meet the requirements of the relevant standards, codes of practice and working drawings.
3.7 Transportation and temporary storage of structures (products) in the installation area should be carried out in accordance with the requirements of state standards for these structures (products), and for non-standardized structures (products), the following requirements must be observed: structures should, as a rule, be in a position corresponding to the design (beams, trusses, slabs, wall panels, etc.), and if this condition cannot be met, in a position convenient for transportation and transfer to installation (columns, flights of stairs, etc.), provided that their strength is ensured; structures should be based on inventory linings and gaskets of rectangular section, located in the places indicated in the project; the thickness of the gaskets must be at least 30 mm and at least 20 mm higher than the height of the sling loops and other protruding parts of the structures; in case of multi-tiered loading and storage of the same type of structures, linings and gaskets should be located on the same vertical along the line of lifting devices (loops, holes) or in other places indicated in the working drawings; structures must be securely fastened to protect against overturning, longitudinal and transverse displacement, mutual impacts on each other or on the structure of vehicles; fastenings should ensure the possibility of unloading each element from vehicles without violating the stability of the rest; textured surfaces of load-bearing structures must be protected from damage and contamination; reinforcement outlets and protruding parts must be protected from damage; factory marking must be accessible for inspection; small parts for mounting connections should be attached to the shipping elements or sent simultaneously with the structures in a container equipped with tags indicating the brands of the parts and their number; these parts should be stored under a canopy; fasteners should be stored indoors, sorted by type and brand, bolts and nuts - by strength classes and diameters, and high-strength bolts, nuts and washers - and by lot.
3.8 Facade cladding and roofing structures with textured and other finishes, thin-walled galvanized elements of load-bearing structures, fasteners and parts of load-bearing and enclosing structures, shaped elements of facade and roofing, insulation and vapor barrier materials should be stored in an unheated warehouse with a hard floor covering. Storage of structures, cladding panels and parts in a warehouse is carried out in a packaged form on wooden beams up to 10 cm thick, with a step of 0.5 m. The warehouse must be closed, dry, with hard flooring. It is not allowed to store the structures, panels and parts specified in this paragraph in open areas and together with aggressive chemical products.
3.9 During storage, structures should be sorted by brands and stacked taking into account the sequence of installation.
3.11 To ensure the safety of wooden structures during transportation and storage, inventory devices (lodges, clamps, containers, soft slings) should be used with installation of soft gaskets and linings in places of support and contact of structures with metal parts. Structures should be stored under a canopy to protect them from exposure to solar radiation, alternating moistening and drying.
3.12 Prefabricated structures should be installed, as a rule, from vehicles or enlargement stands.
3.13 Before lifting each mounting element, it is necessary to check: compliance with its design mark; the condition of embedded products and installation marks, the absence of dirt, snow, ice, damage to the finish, priming and painting; availability of the necessary connecting parts and auxiliary materials at the workplace; correctness and reliability of fastening of load-handling devices. Each mounting element must be equipped in accordance with the PPR with scaffolding, ladders and railings.
3.14 Slinging of mounted elements should be carried out in the places indicated in the working drawings, and ensure their lifting and supply to the installation site in a position close to the design one. If it is necessary to change the places of slinging, they must be agreed with the organization - the developer of the working drawings. Lifting operations with thin-walled galvanized structures, facing panels and slabs should be carried out using textile tape slings, vacuum grippers or other devices that prevent damage to structures and panels. It is forbidden to sling structures in arbitrary places, as well as for the release of reinforcement. Slinging schemes for enlarged flat and spatial blocks must ensure their strength, stability and invariability of geometric dimensions and shapes when lifting.
3.15 Mounted elements should be lifted smoothly, without jerks, rocking and rotation, as a rule, using braces. When lifting vertically located structures, one guy is used, horizontal elements and blocks - at least two. The structures should be lifted in two stages: first, to a height of 20–30 cm, then, after checking the reliability of the slinging, further lifting should be carried out.
3.16 When installing mounting elements, the following must be ensured: stability and immutability of their position at all stages of installation; work safety; the accuracy of their position with the help of constant geodetic control; strength of mounting connections.
3.17 Structures should be installed in the design position according to the accepted guidelines (risks, pins, stops, edges, etc.). Structures with special embedded or other fixing devices should be installed on these devices.
3.18 Installed mounting elements must be securely fastened before bridging.
3.19 Until the end of the reconciliation and reliable (temporary or design) fixing of the installed element, it is not allowed to rest on it the overlying structures, if such support is not provided for by the PPR.
3.20 If there are no special requirements in the working drawings, the maximum deviations of the alignment of landmarks (edges or marks) during the installation of prefabricated elements, as well as deviations from the design position of structures completed by installation (erection) should not exceed the values given in the relevant sections of this set of rules.
