Practice shows that today the main trend in the development of the modern construction industry is associated with the expansion of the use of cast-in-situ reinforced concrete. In many cases, cast-in-situ reinforced concrete has better construction and technological properties (compared to precast concrete, metal) and allows you to freely implement a variety of architectural solutions with economic benefits. In turn, modern advances in the technology of concrete work would not be possible without the appropriate technical base. This article analyzes the use of construction machines in the construction of a cast-in-situ reinforced concrete skeleton of civil buildings on the example of objects realized in Yekaterinburg. A study was conducted, according to the results of which the manufacturers of construction equipment were identified, as well as the technologies prevailing in monolithic housing construction in the city. According to the terms and cost of construction, which are the defining elements of the construction sector, one indicator was allocated for a technical and economic comparison, the results of which determined the need to develop a comprehensive feasibility study of the use of construction machines in the construction of cast-in-situ load-bearing reinforced concrete structures, as well as the development of methods for selecting machines, which in the future will reduce the construction time of the cast-in-situ skeleton of the building, increase the payback of monolithic civil housing construction and the efficiency of construction from cast-in-situ reinforced concrete.
