Operational control of construction and installation works. Operational quality control charts for the main construction and installation works
11.9.1 During the execution of production processes and operations, operational control is carried out in order to identify defects that may be hidden during the continuation of the process or operation, and to take measures to prevent and eliminate these defects.
11.9.2 By operational control the person carrying out the construction checks:
Compliance with the sequence and composition of the technological operations performed with the technological and regulatory documentation that applies to these technological operations;
Compliance with technological regimes established by technological maps and regulations;
Compliance of the quality indicators of the operations and their results with the requirements of the design and technological documentation, as well as the 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 object, but in accordance with the adopted technology, they become unavailable for control after the start of subsequent work, as well as the performed building structures and sections of engineering networks, the elimination of defects identified by control is impossible without disassembling or damaging subsequent structures and sections of engineering networks. Representatives of the relevant bodies of state supervision, architectural supervision, as well as, if necessary, independent experts can participate in these control procedures. The contractor notifies the rest of the participants about the timing of these procedures no later than three working days in advance.
11.9.3 The results of acceptance of works hidden by subsequent works, in accordance with the requirements of the design and regulatory documentation, are drawn up by certificates of inspection of hidden works ( appendix M ). The developer (customer) may require a re-survey after elimination of the identified defects.
11.9.4 To the procedure for assessing the conformity of individual structures, tiers of structures (floors), the contractor must submit certificates of survey of all hidden works that are part of these structures, geodetic executive schemes, as well as test reports of structures in cases provided for by the design documentation and (or) a construction contract. The developer (customer) can check the reliability of the executive geodetic schemes presented by the contractor. To this end, the contractor must keep, until the completion of the acceptance, the fixed axes and installation guidelines fixed in nature.
The results of the acceptance of individual structures must be formalized by acts of acceptance of critical structures ( appendix H ).
11.9.5 Tests of sections of engineering networks and mounted engineering equipment are carried out in accordance with the requirements of the relevant regulatory documents and are drawn up by acts of acceptance of critical structures (Appendix H).
11.9.6 If, as a result of the gradual acceptance of defects in work, structures, sections of engineering networks, the corresponding acts should be drawn up only after the elimination of the identified defects.
In cases where subsequent work should begin after a break of more than 6 months from the date of completion of the stage-by-stage acceptance, these procedures should be repeated before the resumption of work with the issuance of the relevant acts.
11.9.7 Places of performance of control operations, their frequency, performers, methods and measuring instruments, forms of recording results, the procedure for making decisions when detecting non-compliance with the established requirements must comply with the requirements of design, technological and regulatory documentation.
11.9.8 The person carrying out the construction appoints by his administrative documents the responsible executors for the implementation of operational control, documenting its results and elimination of defects identified by the control.
The results of operational control should be documented in special work logs.
