Investigation of labour intensity and duration of the assembly processes of structural covering blocks

Abstract

The article considers an approach to determining the labor-intensiveness and duration of consolidation processes during the installation of structural blocks of the covering, which is caused by atypical structural and technological solutions. The relevance of this work is the need for a qualitative analysis of methods for calculating the labor intensity and duration of technological processes when justifying and making decisions regarding the organization and mechanization of assembly processes. Modern technologies of installation of structural blocks of coatings are analyzed. The analysis of labor costs was carried out for the option of using load-lifting assembly modules to reduce the specific share of the use of heavy crane equipment at the construction site. In comparison, the method of installing a structural coating using heavy crane equipment and load-lifting assembly modules is considered. To ensure the principle of comparison of options, the processes of column installation, stand installation, block consolidation, block installation, and installation and movement of a crane or assembly lifting and gathering modules are included in the consideration. All calculations were performed in tabular form according to the formula of the integer normalization method. Based on the results of the study, all the components of the labor intensity and duration of the processes were determined, on the basis of which the schedules of the consolidation and installation of the SBP blocks were built.
