Quality Control of Repair and Construction Works in Ensuring the Operational Safety of Buildings and Structures

Abstract

AbstractThis article describes the developed testing procedure in the laboratory and on the construction site as part of the incoming quality control. The “testing” procedure is carried out within the framework of the developed rules, according to ISO 9001 and ISO / IEC 17025, and is presented in the form of an algorithm, which is described using the IDEF0 methodology and the PDCA cycle. The decomposition of the testing process determines the steps of testing, which allows any laboratory scientist to understand and follow this approach in a detailed study of the job description. If inconsistencies are identified in the procedure, corrective and preventive measures are taken. In order to plan and analyze the results of quality control of the testing, periodic retests between laboratory scientists (internal proficiency testing) should be carried out. The final step of the testing procedure is the preparation of a protocol, which is filled out based on job history cards or workbooks. The content of the test protocol must strictly comply with the requirements set out in ISO/IEC 17025 «General requirements for the competence of testing and calibration laboratories». The test protocol must be signed by the persons who conducted the tests, approved by the head (deputy head) of the testing laboratory and sealed by the testing laboratory. The developed procedure for conducting tests during the implementation of incoming control makes it possible to identify discrepancies in time and makes it possible to eliminate the risks of using low-quality materials, which significantly increases operational safety during the facility operation.KeywordsOperational safetyQuality controlConstruction control
