Operational control of construction and installation works. Cards of operational quality control of the main construction and installation works
11.9.1 During the performance 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 by the technological and regulatory documentation applicable to these technological operations;
Compliance with the technological regimes established technological maps and regulations;
Compliance of the quality indicators of the performance 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, should be carried out. object, but in accordance with the accepted technology, they become unavailable for control after the start of the subsequent work, as well as the completed building structures and sections of engineering networks, the elimination of defects of which, identified by the control, is impossible without dismantling 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 may participate in these control procedures. The performer of works not later than three working days notifies the other participants about the timing of the specified procedures.
11.9.3 The results of the acceptance of work hidden by subsequent work, in accordance with the requirements of the design and regulatory documentation, are documented in certificates of survey of hidden work ( Annex M ). The builder (customer) may require a re-examination after the elimination of the identified defects.
11.9.4 To the procedure for assessing the conformity of individual structures, tiers of structures (floors), the performer of the work must submit certificates of survey of all hidden works that are part of these structures, geodetic executive schemes, as well as test reports for structures in cases provided for by the design documentation and (or) building contract. The developer (customer) can perform verification of the reliability of the executive geodetic schemes submitted by the contractor. To this end, the performer of the work must keep, until the completion of the acceptance, the alignment axes and mounting landmarks fixed in kind.
The results of acceptance of individual structures should be documented in acts of acceptance of critical structures ( annex H ).
11.9.5 Tests of sections of engineering networks and installed engineering equipment are carried out in accordance with the requirements of the relevant regulatory documents and are documented in acts of acceptance of critical structures (Appendix H).
11.9.6 If, as a result of phased acceptance, defects in works, structures, sections of engineering networks are detected, the relevant acts should 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 moment the phased acceptance is completed, these procedures should be repeated before the resumption of work 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, decision-making procedures in case of detection of 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 by its administrative documents responsible executors for the performance of operational control, documentation of its results and elimination of defects identified by the control.
The results of operational control should be documented in special work logs.
