QUALITY OF PERFORMANCE OF CONSTRUCTION AND ASSEMBLY WORKS
BUILDING LITERATURE PUBLISHING
Recommendations for the implementation of operational quality control of the construction and installation work were developed by the Central Scientific Research Institute of Industrial Construction of the USSR Gosstroy (executed by engineer E. M. Zolotnikov), NIISP of the State Construction Committee of the Ukrainian SSR (executor by LI Pokrass)
If-III plan ". 1971, M 14
1. These Recommendations establish a general procedure for operational quality control of construction and installation and special construction work during the construction of buildings and structures for various purposes, being built in ordinary areas and in areas with special natural conditions (seismic, the spread of permafrost subsidence and other soils, etc. .).
2. Recommendations are mandatory for construction and installation and specialized construction organizations, regardless of their departmental subordination, as well as for technical supervision of the customer (developer), designer supervision of design organizations.
3. The main tasks of operational quality control of construction and installation and special construction works are:
ensuring the compliance of the construction, installation and special construction work performed with the project and the requirements of regulatory documents for construction. approved or agreed by the USSR State Construction Committee;
timely identification of the causes of defects in the production of work and taking measures to eliminate them;
increasing the responsibility of direct executors (workers, teams) for the quality of work.
4. Operational control of the quality of construction and installation work is assigned to the work producers and foremen who are in charge of the construction of buildings and structures.
In necessary cases, construction laboratories and geodetic and mine surveying services, as well as specialists involved in the control of certain types of work, are involved in operational control;
carried out in accordance with the schemes of operational quality control of work performance (SQC),
attached to the flow charts, which are an integral part of the work production projects (PPR). approved by engineers of construction and installation or specialized construction organizations in accordance with the Instruction on the procedure for drawing up and approving. waiting for projects of organization of construction and projects for the production of work (SN 47-67), approved by the USSR State Construction Committee.
For the construction of facilities for which technological maps are not developed, groups for the preparation of production and design of the production of works of construction organizations are required to issue standard or repeated use of SOKK.
5. Compilation of the SOKK is carried out on the basis of the requirements of regulatory documents for construction and state standards.
6. SOKK should contain:
sketches of structures indicating the permissible deviations according to SNiP, and, if necessary, the main characteristics of the quality of the material or structures (strength, frost resistance, fire resistance, etc.);
a list of operations, the performance of which must be checked by the work supervisor or foreman;
data on the composition of the control, established on the basis of the requirements of regulatory documents for construction and working drawings, indicating what needs to be checked (for example, the cross-section of reinforcement and the location of reinforcing bars; compliance of the actual dimensions of the elements with the design ones; monolithing of floor slabs and coatings, their relationship to each other , as well as with straps and anti-seismic belts, etc.);
an indication of the method of control of the operations performed - how and by what the check should be carried out (visually, instrumentally - the name of the measuring devices and tools, etc.);
the timing of the control;
a list of hidden works to be handed over to the technical supervision representatives of the customer (developer);
the list of operations controlled with the participation of a construction laboratory, geodetic and mine surveying service (compliance with the geometric parameters of the project, the accuracy of transferring design data to nature
etc.), as well as specialists involved in the control of certain types of work;
The scheme is drawn in the format 420X297 mm, which is reduced during reprinting to the required size.
An example of SQC is given in the appendix.
7. The list of hidden works to be handed over to the customer's technical supervision representatives is determined by the drafters of the SOKK on the basis of SNiP and other regulatory documents, while the sequence of delivery of hidden works is indicated (for example, welding of embedded parts before the production of anti-corrosion protection, etc.).
Note. The specified list must necessarily include work on the laying of outlets of reinforcement (anchors) in foundations, supports, ceilings in order to use them when installing anti-seismic belts.
8. When determining the list of operations controlled with the participation of a construction laboratory, a geodetic and mine survey service, as well as specialists involved in the control of certain types of work, one should be guided by the current Model Regulations on laboratories of construction and installation organizations and their production enterprises, the Regulation on the Geodetic and Mine Surveying Service in construction and installation organizations and other regulatory documents approved or agreed by the USSR State Construction Committee.
9. SOKK are developed by orders of contracting construction organizations by Orgtekhstroy trusts (Org-stroy), groups for preparation and design of production of work of construction and installation and specialized construction organizations, and for experimental construction - by design and research institutes.
10. The management of the construction and installation or specialized construction organization, no later than 15 days before the commencement of work, must transfer to the direct supervisor of the construction of a building or structure (manufacturer of works, foreman) of the SOKK complete with PPR and technological maps. SOKK must be presented at the request of persons supervising the quality of construction.
11. The beginning of construction and installation and special construction work must be preceded by a check
manufacturers of works and craftsmen with the participation, if necessary, of representatives of construction laboratories for the quality of building materials, products, semi-finished products, structures (as they are received for construction), as well as the compliance of these passports and certificates for them with the requirements of the projects.
12. All defects identified during the operational control (deviations from projects, standards, requirements of regulatory documents for construction) must be eliminated before the start of subsequent operations (works).
13. The organization of operational control and the establishment of supervision over its implementation are entrusted to the heads and chief engineers of construction and installation and specialized construction organizations (sites, departments, trusts, etc.).
14. Chief engineers of construction and installation and specialized construction organizations must, prior to starting work at the facility, ensure:
instructing the line engineering and technical personnel of construction sites and workshops on the procedure for conducting operational control, drawn up by a corresponding entry in the log of works on the construction of the facility;
the study by all engineering and technical workers and workers of the SNiP requirements when performing construction and installation work in areas with special natural conditions, checking the knowledge of these workers, registering the results of this check;
instructing newly recruited engineering and technical workers on the procedure for implementing operational quality control of work.
15. Engineering and technical workers carrying out operational control of the quality of construction, installation and special construction works are obliged to keep records of production defects and defects identified in the process of this control, and to enter them in the logs of works on the construction of objects.

Technological control consists in checking the compliance of characteristics, modes and other indicators of the technological process with the established requirements. A kind of technological control is operational control. At operational control product quality is checked for compliance with individual regulatory requirements implemented in the course of the next technological operation. Its purpose is to detect and eliminate defects in the process of manufacturing products or erecting buildings and structures. Operational control is performed by production personnel (workers, foremen, foremen). This type of control is considered to be labor quality control.
During operational control, check:
Hidden parameters of the product, the control of which is subsequently impossible or difficult (reinforcing cages, etc.);
Compliance with the technology for performing construction processes specified in the work production projects;
Compliance of the work performed with working drawings, building codes and regulations for the production of work and standards;
Stability of the parameters of products included in the nomenclature for control of finished products;
Product parameters depending on the quality and condition of technological equipment and technological process (thickness of the concrete cover, location of embedded parts, curvature and non-straightness of the surface).
Operational control is carried out according to special schemes of operational quality control (SOKK) for all construction and installation processes attached to the flow charts or workflow charts. SOKK is a project document that defines the performers, composition, method and time of quality control of construction processes for operations. It is developed based on the requirements of regulatory documents and state standards. It lists specific operations and indicates the requirements of the standard (or building codes and regulations) to be followed when performing this operation, and also provides a description of the tool with which the operational control is carried out. The map also indicates who specifically controls (worker, foreman, foreman, technical control department, etc.).
Operational control should be carried out after the completion of production operations or construction processes and ensure the timely identification of defects and the reasons for their occurrence, and
timely adoption of measures to eliminate and prevent them.
Operational control should be carried out by work producers and foremen, and self-control by work performers. Operational control should also involve construction laboratories and geodetic services. The main working documents for operational quality control should be operational control schemes developed as part of work production projects.
The operational control scheme should contain:
- sketches of structures with an indication of the permissible deviations in dimensions and the required measurement accuracy, as well as information on the required characteristics of the quality of materials;
- a list of operations or processes, the quality of which must be checked by the work manufacturer (foreman);
- a list of operations or processes controlled with the participation of a construction laboratory and a geodetic service;
- a list of hidden works subject to certification with the drawing up of an act;
- the requirements of building codes and regulations, and, if necessary, the main characteristics of the quality of the material (structures);
- data on the composition of the control, established on the basis of the requirements of regulatory documents and working drawings, indicating what needs to be checked;
- instructions on how to control the operations performed;
- the timing of the control.
Operational control is entrusted to foremen and foremen, and its organization to chief engineers of construction and installation organizations.
7. Acceptance control.
Acceptance control finished products are carried out at the final stage of the technological process. The number of parameters checked in this case must meet the requirements of standards and building codes and regulations. Internal inspection control is carried out according to the schedule approved by the management of the enterprise, usually at least once a quarter. Acceptance control should be carried out to check and assess the quality of completed construction enterprises, buildings and structures or their parts, as well as hidden works and individual critical structures. All hidden works are subject to acceptance with the drawing up of acts from the certified one. The certificate of inspection of hidden works should be drawn up for a completed process performed by an independent unit of performers. Drawing up certificates of inspection of hidden work in cases where subsequent work should begin after a long break, should be carried out immediately before the production of subsequent work. Individual critical structures, as soon as they are ready, are subject to acceptance during the construction process with the preparation of an intermediate acceptance certificate for these structures. The list of critical structures subject to interim acceptance is established by the project.
In addition to production control in construction and installation organizations (input, operational, acceptance) the quality of construction is monitored by state and departmental bodies of control and supervision, acting on the basis of special provisions on them (fire, sanitary, mining, etc.). In construction organizations, organizational, technical and economic measures should be developed to ensure quality control of construction. These events should, in parity, provide for the creation of construction laboratories, geodetic services, advanced training and skills of performers. At all stages of construction, in order to check the effectiveness of previously performed production control, selectively carry out inspection control... It is carried out by special services, if they are part of the construction organization, or by commissions specially created for this purpose. According to the results production and inspection quality control Construction and installation works are developing measures to eliminate the identified defects, while taking into account the requirements of designer supervision of design organizations and state supervision bodies.
