Guidelines for quality control of construction and installation works. Operational quality control Map of operational control of brickwork walls

Technological control consists of checking the compliance of characteristics, modes and other indicators technological process established requirements. A type of technological control is operational control. At operational control product quality checks compliance with specific regulatory requirements, implemented during the execution of the next technological operation. Its purpose is to detect and eliminate defects in the process of manufacturing products or constructing buildings and structures. Performer operational control is production personnel (workers, foremen, foremen). This type of control is considered as labor quality control.

During operational control the following is checked:

Hidden parameters of the product, control of which is subsequently impossible or difficult ( reinforcement cages and so on.);

Compliance with the execution technology specified in work production projects construction processes;

Compliance of the work performed with working drawings, construction codes and work regulations and standards;

Stability of parameters of products included in the control range finished products;

Product parameters depending on quality and condition technological equipment and technological process (thickness of the protective layer of concrete, location of embedded parts, curvature and non-straightness of the surface).

Operational control is carried out according to special operational quality control schemes (OSQC) for all construction and installation processes, attached to technological maps or maps of labor processes. 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 requirements regulatory documents And state standards. It lists specific operations and indicates the requirements of the standard (or building codes) that are observed when performing this operation, and also provides a description of the tool with which operational control is carried out. The card also indicates who specifically carries out control (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 causes of their occurrence, as well as

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. Construction laboratories and geodetic services should also be involved in operational control. The main working documents for operational quality control should be operational control schemes developed as part of work projects.

The operational control scheme must contain:

1. design sketches indicating permissible deviations in dimensions and required measurement accuracy, as well as information on the required quality characteristics of materials;
2. a list of operations or processes, the quality of which must be checked by the work performer (foreman);
3. a list of operations or processes controlled with the participation of the construction laboratory and geodetic service;
4. a list of hidden works that are subject to inspection and the drawing up of a report;
5. requirements of building codes and regulations, and, where necessary, the main characteristics of the quality of the material (structure);
6. 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;
7. instructions on the method of monitoring performed operations;
8. timing of control.

Operational control is entrusted to foremen and foremen, and its organization is entrusted 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 must meet the requirements of standards and building codes. Internal inspection control is carried out according to a 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 of enterprises, buildings and structures or their parts, as well as hidden work and individual critical structures. All hidden work is subject to acceptance with the drawing up of inspection reports. An inspection report for hidden work must be drawn up for a completed process carried out by an independent department of performers. Drawing up inspection reports for hidden work in cases where subsequent work must begin after a long break should be carried out immediately before subsequent work is carried out. Individual critical structures, as they are ready, are subject to acceptance during the construction process with the preparation of an interim acceptance certificate for these structures. The list of critical structures subject to intermediate 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 control and supervision bodies, acting on the basis of special provisions on them (fire, sanitary, mining, etc.). Construction organizations must develop organizational, technical and economic measures aimed at ensuring construction quality control. These activities should, in parity, include the creation of construction laboratories, geodetic services, advanced training and skill of performers. At all stages of construction, in order to check the effectiveness of previously performed production controls, 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 work develops measures to eliminate identified defects, taking into account the requirements of designer's supervision design organizations and government oversight bodies.

11.9.1 During production processes and operations, operational controls are carried out in order to identify defects that may be hidden if the process or operation continues, and to take measures to prevent and eliminate these defects.

11.9.2 With operational control, the person carrying out construction checks:

Compliance of the sequence and composition of the technological operations performed with the technological and regulatory documentation applicable to these technological operations;

Compliance with the technological regimes established technological maps and regulations;

Compliance of quality indicators of operations and their results with the requirements of design and technological documentation, as well as regulatory documentation applicable to these technological operations.

11.9.2 During the construction process, an assessment of the work performed, the results of which affect safety, must be carried out object, but in accordance with the adopted technology become unavailable for control after the start of subsequent work, as well as completed building structures and plots utility networks, the elimination of defects identified by inspection is impossible without dismantling or damaging subsequent structures and sections of utility networks. Representatives of the relevant state supervision bodies, designer’s supervision, as well as, if necessary, independent experts may participate in these control procedures. The contractor notifies the other participants of the timing of these procedures no later than three working days in advance.

11.9.3 The results of acceptance of work hidden by subsequent work, in accordance with the requirements of design and regulatory documentation, are documented in certificates of inspection of hidden work ( Appendix M ). The developer (customer) may require a re-inspection after eliminating the identified defects.

11.9.4 To the procedure for assessing the conformity of individual structures, tiers of structures (floors), the work performer must submit inspection reports of all hidden works included in these structures, geodetic as-built diagrams, as well as test reports for structures in cases provided for in the design documentation and (or) construction contract. The developer (customer) can check the accuracy of the as-built geodetic schemes presented by the contractor. For this purpose, the performer of the work must preserve the alignment axes and installation guidelines fixed in kind until the completion of acceptance.

The results of acceptance of individual structures must be documented in acceptance certificates for critical structures ( Appendix H ).

11.9.5 Tests of sections of utility networks and installed utility equipment are carried out in accordance with the requirements of the relevant regulatory documents and are documented in acceptance certificates for critical structures (Appendix H).

11.9.6 If defects in work, structures, or sections of utility networks are discovered as a result of stage-by-stage acceptance, the corresponding acts must be drawn up only after the identified defects have been eliminated.

In cases where subsequent work must begin after a break of more than 6 months from the completion of phased acceptance, before resuming work, these procedures should be repeated with the execution of the relevant acts.

11.9.7 Places for performing control operations, their frequency, performers, methods and measuring instruments, forms for recording results, the procedure for making decisions when identifying non-compliance with established requirements must comply with the requirements of design, technological and regulatory documentation.

11.9.8 The person carrying out the construction appoints with his administrative documents the responsible executors for performing operational control, documenting its results and eliminating defects identified by the control.

The results of operational control must be documented in special work logs.
