Decrease in the Quality of Construction Due to the Imperfection of the Regulatory Framework

The problem of quality control and evaluation in construction is becoming particularly relevant today, since the efficiency of quality management services in the construction complex is not high enough. At all stages of the life cycle of construction products, the main goal of the participants in the construction process is to create a safe and reliable capital construction facility, and all actions should be aimed at optimizing business processes and reducing risks at all stages of the life cycle of buildings, etc. The current regulatory requirements for quality control in construction, in particular for concrete and concrete mix, their indicators, permissible deviations and stability of quality indicators were investigated. The absence of the use of statistical tools to ensure the stability of the production of concrete mixtures, control of quality indicators of products and processes producing products has been revealed. The requirements for cement quality indicators, in particular the activity and strength of cement, were also analyzed. It was found that in the latest versions of regulatory documents there are no methods for controlling the strength and uniformity of concrete to achieve the constancy of the production process and the indicators adopted for the concrete grade. Operational control is carried out by filling out electronic forms provided for in the control plan for each type of work and participant in the construction process, including on the basis of operational quality control schemes of technological documentation of construction/ But, the regulatory document does not specify who develops the control plan, questionnaires and in what volume, etc. This must be stipulated in the contract for the performance of work. As a result, the availability of standards approved and applied on a voluntary basis for the manufacture and use of construction materials, the production of construction and installation works due to existing shortcomings does not fully guarantee the creation of a reliable and safe capital construction facility.
