Modeling the residential buildings erection of large-sized blocks

Abstract

Introduction. the development analysis of domestic residential building construction of volumetric blocks, starting from the 60s of the twentieth century to the present time, is given. It is noted the innovative nature of the transition from low- volume blocks to large-sized blocks of high and full factory readiness. The problems that have arisen in this case are indicated, of which one of the most acute is the determination of organizational and technological parameters for the construction of residential buildings. Materials and methods. the role of organizational and technological parameters of the objects’ construction is described — the duration of construction and its stages, the complexity of work, the number of workers. The content of the timing carried out by the MonArch Group of Companies for the installation of large-sized volumetric blocks of a four-story residential building in Yakovlevo–2 village (New Moscow) is revealed. The main installation operations are analyzed with an indication of the time spent on each floor and the roof arrangement. Results. based on the final results of the timekeeping materials generalization, three estimates of the duration of a building construction of large-sized blocks are proposed — pessimistic, satisfactory, optimistic. The found dependences “duration of building construction — the number of large–sized blocks installed taking into account the roof arrangement” are revealed with the corresponding calculation formulas. The formula for calculating the labor intensity of installers work and crane maintenance workers is also given. Conclusions. the prospects for the innovative technology development for the construction of residential buildings of large-sized blocks are substantiated, provided that capital investments are allocated and the efforts of research and design organizations are combined to comprehensively solve the problems that have arisen. To solve the problematic tasks of determining the indicators of organizational and technological parameters of buildings construction of large-sized blocks, an approach and methods for assessing the duration of construction and the complexity of installation work on the assembly of buildings are proposed.
