The article highlights a number of problems that accompany the process of managing the property complex of the territory of the municipality. Issues related to the accounting and analysis of the state of objects of the property complex are considered. The need for systematic research is noted to justify decisions on the use of the city as a resource that provides a comfortable and safe space for life. Improving the process of managing the property complex is an urgent task for the development of cities around the world. An analysis of foreign experience indicates a common understanding of the criteria for the quality of the urban environment and the goals of the reorganization of urban space. When planning the development of urbanized territories, the peculiarities of the city, natural and climatic conditions are not always taken into account, which has a detrimental effect on the quality of the urban environment. It is shown that the effectiveness of the management of the property complex depends on the correct choice of the strategy for involving objects in the economic turnover, restoring their functional significance and ensuring environmental safety. To select effective solutions when solving issues of the use of the territory, it is proposed to use the method based on fuzzy sets, as the most optimal in conditions of high uncertainty and complexity of the processes under consideration.

The article discusses the basic principles of information modeling of building systems that underlie BIM technology, and emphasizes the importance of their interaction, since the correctness and efficiency of the BIM process depends on this. The traditional and some basic curves characteristic of the life cycle of goods (products), which have found application in marketing theory, is given. It is noted that each stage of the life cycle of a construction object requires in-depth study and detailed study, since the analysis of scientific publications and the current regulatory document on information modeling revealed their contradiction to each other in some positions.

Keywords: information modeling, principles, life cycle curves, capital construction object, normative document.

When clearing territories for the construction and / or subsequent maintenance of such infrastructure facilities as construction sites, airfield territories, right-of-way for roads and railways, heat supply routes, and so on, work is often carried out to remove growing undesirable tree and shrub vegetation, At the same time, the problem of assessing the quality of the performance of these works is relevant. The authors of the article consider the issues of mathematical modeling for assessing the quality and effectiveness of the work performed to clear the territories of a number of the above infrastructure facilities, give the boundary values ​​of the criteria for assessing the quality of the measures taken to remove vegetation, and formulate a conclusion about the advantages of the developed mathematical model.

The importance of ensuring reliable operation of steel vertical tanks is emphasized. Based on the analysis of a number of scientific publications and regulatory documents, the most characteristic defects are presented in tabular form by groups, the combination of which determines the choice of the method of overhaul or reconstruction of tanks. In accordance with the data given in the table, the most common methods of overhaul and reconstruction of steel vertical tanks are considered.It is noted the need to develop organizational and technological solutions based on information technology, using servers for monitoring through the GLONASS / GPS systems, which will allow, within the framework of monitoring, to detect defects and damage to structural elements in a timely manner during the operation stage and ensure their elimination in order to increase the residual life of vertical steel tanks .

The work is devoted to the study of the possibilities of ensuring the unconditional achievement of the goals of industrial enterprises with a combination of modal management and linear regulation with cost optimization in the operational and tactical management of quality management systems. The commonality of dependencies in modal control and linear regulation is shown. An approach to the combination of modal control and linear regulation is proposed, including the determination of the possibilities for changing the elements of the system matrix, as well as the search for optimal or rational solutions based on cost accounting. The application of this approach is considered on the example of the activity of an industrial enterprise. It is established that modal control has no advantages over linear control, since it is used to increase the stability of systems. The performance of quality management systems can be ensured when it is transferred to an unstable mode of operation, however, the use of this mode cannot exceed two to three years.

The development of urbanized territories, as a rule, is associated with the expansion of urban space, which, in turn, leads to an increase in the load on transport systems and social infrastructure. Geographically divided areas have weak interconnection due to the lack of highways and public transport. At the same time, the infrastructure of the outskirts differs from the center in scarcity and monotony. An increase in the urban population, a change in the natural and climatic conditions of residence, the environment in urbanized areas, a steady increase in the value of real estate make it necessary to accelerate the pace of the integrated development of urban spaces. The most important task set today for the subjects of management of the municipality is related to the optimization and effective use of the objects of the existing property complex. The renovation process will affect morally obsolete and abandoned facilities that impede the integrated development of the territory, reduce investment attractiveness and reduce the volume of the tax base. Adaptive management will increase the efficiency of the use of existing territorial resources, improve the social and environmental conditions of the urbanized space. Involvement of the existing reserve of real estate objects in the city center will create conditions for the formation of new public and business spaces in the city, which is important for the comfortable living of the population.
