Accuracy estimate of technological processes as exemplified by construction works

Abstract

The article proposes a calculating method the accuracy of technological processes, taking into account the peculiar features of construction. It gives a graphical interpretation of process accuracy indicators for normal parameter distribution. It shows the differences in approaches to estimating accuracy. It provides actual data on the accuracy of installation works. The method of calculating the process accuracy takes into account the seriousness of defects and the criticality rating of buildings and structures. The article shows the relationship between the indicators of accuracy and defectiveness. The proposed calculation procedure ensures a more accurate estimate of the ratio of the tolerance to the parameter spread. The procedure allows us to estimate the accuracy of construction processes and, if necessary, to adjust the methods of work performance and quality control in order to achieve the specified accuracy.
