Organization of quality control of earthworks and concreting during construction of the Zagorsk pumped-storage station

Abstract

1. The quality control system created at the Zagorsk PSS mainly provides quality control of construction. However, the repeated transfer of control from one firm to another leads to the loss of primary documents needed for putting the structure into service. 2. The absence of test equipment (tensile-test machines of more than 100 tons, freezers, etc.) does not permit conducting tests in good time and to the full extent. 3. It is necessary to solve the problem of appropriate financing of the control service (at least 1% of the cost of construction and assembly works).
