“…Formation of hidden defects (for example, micro cracks) caused by a failure to conform to the technologies of manufacturing, transportation, installation or dismantling works or inappropriate operating conditions is primarily determined by specific metallurgical, physical and chemical properties of the material. [3] Cast iron is an alloy of iron with carbon and other chemical elements. The carbon content in cast iron exceeds 2.14 %.…”

Dynamic expansion of the extensive network of facilities of the Moscow Metro prompts the development of relevant control techniques that would facilitate the commissioning of transport and related facilities in a timely manner and at an appropriate quality level subject to the effective safety and reliability legislative requirements. This article describes the prerequisites for development of comprehensive technical inspection of metro facilities with reference to the supporting regulatory and technical base. The study primarily deals with the criteria, tolerances and control methods with respect to components of tunnel linings and other underground structures of rapid transit systems due to the apparent great significance of these structures in ensuring safety and reliability of future facilities after commissioning. Arguments are also given for the need for such technical surveying with account of the current situation in terms of the quality of prefabricated linings supplied and used in metro facilities.

To optimize the organizational and technological model of construction of buildings and structures in a dense urban environment, it is necessary to take into account the factors that have a destabilizing effect on the process of construction and installation works, and arising from the very definition of " constrained urban development", which involves getting near buildings, structures and linearly extended objects in the zone of influence of new construction or reconstruction. This article highlights a number of destabilizing factors that most strongly affect the time and economic costs that must be considered when developing a construction project.

“…As a consequence, a unified organizational structure can be formalized by separating individual operations therein ( Figure 2). Due to the fact that major facilities subject to industrial area redevelopment are hierarchically structured with different numbers of levels and different target functions (functional efficiency criterion), the most efficient solutions require multi-level and multiobjective systemic optimization with account of links in structural and functional subsystems [2]. However, the necessary assessment level for such links remains beyond the limits of comprehensive analysis due to the difficulties in processing large data volumes.…”

A large number of large industrial cities around the world are characterized by the presence of industrial sites in the Central part of the city and areas close to the center. A significant part of these zones have lost their relevance and are not used as production facilities, but function as rental businesses. The relevance of the study considered in this article is due to the need to create an organizational and technological model for the development of project documentation for the redevelopment of industrial facilities in the absence of Federal and regional programs in Russia that affect this area, as well as the lack of a regulatory framework for regulating the activities of project organizations that develop the above projects. The article deals with the General principles of developing an organizational and technological model that allows evaluating and optimizing the designer’s activity when repurposing industrial objects, as well as aimed at improving the design processes of such objects. For scientific, methodological and system-technical bases of designing organizational structures of enterprises and organization of production processes of modeling re-profiling of industrial territories, it was necessary to solve the following tasks: study and generalization of foreign and domestic experiences of redevelopment of industrial zones; identification of actual problems in the design of redevelopment of industrial territories; study of factors that affect the effectiveness of the designer; establishing the degree of influence of the identified factors on the quality of the project documentation produced. The parameters and organizational principles described in the article are taken into account when re-profiling industrial objects in the urban environment of large Russian megalopolises.
