This article studies territorial transformations, along with the management of rural settlements, carried out by the Russian government in the 19th–early 20th centuries. The methods of historiographic and cartographic analysis, as well as the study of archival sources and statistical data, were used. The work was carried out in two stages: identification of the land-use pattern at the state level within the contem-porary borders of administrative structure; study of the management of the relocation process and def-inition of basic principles in the planning of migration sites. A retrospective analysis of the land use as-sociated with a rural community was presented as diagrams and cartographic materials reflecting the state of territorial development in migration areas. The collected historiographic materials, statistical data and regulatory support reflect the main methods for managing the relocation process and the ex-perience of planning rural settlement at the state level. The migration areas were allocated from free state reserves in the form of individual farms and plots of land. The process management was based on a system of committees involving various specialists, whose tasks included the organisation of so-cial and engineering infrastructure. The performed study of the settlement territory, the allocation of lands for farming societies and minorities, the ordering of the existing land use and the identification of the economic and agricultural potential of the region comprise the methods of the preliminary compre-hensive analysis of the territory during settlement planning. The obtained results are essential for ana-lysing the dynamics of territorial development and studying methods and practices of territorial plan-ning of the rural settlement system.

In this work, the issues arising during the construction of low-rise buildings in Eastern Siberia in 2021–2022 were addressed, including the changes associated with the special military operation and West-ern and the USA sanctions against Russia. Attention was paid to the characterisation of the main tech-nologies used in the construction of low-rise buildings. The necessity of using novel approaches to solving the problems associated with the implementation of engineering infrastructure facilities, in-tended as components of new low-rise construction projects, was substantiated. 90% of low-rise build-ings comprise private suburban wooden houses, most suitable for living in an area characterised by a harsh climate. Among the used construction materials, rounded logs, laminated veneer lumber, bricks, cellular concrete, and aerated concrete should be mentioned. Naturalness, environmental friendliness and low thermal conductivity are among the advantages of wooden constructions. Due to certain limita-tions of the regulatory framework in the construction industry associated with low-rise buildings, it is necessary to improve legislation in this area, as well as strengthen control over the quality of work. The main issues were addressed, including rising prices for construction materials, a reduction in incomes, a delay in obtaining a building permit, weak competition and a small number of modern equipment. The main trends in the development of low-rise construction, the potential of the modern construction in-dustry in Eastern Siberia, its prospects and modernisation were determined.

This work addressed the problems of using information modelling in road facilities. One of the main scientific and technical tasks of implementing information modelling in the field of design and construc-tion of highways and engineering structures lies in its use throughout the entire life cycle of a road facility. It was revealed that such models should include the geometric characteristics of road facilities, local conditions in which they are located and basic data on the occurring processes. The applicability of information models at different stages of construction, reconstruction and reconditioning of roads and engineering structures were considered in order to ensure continuous monitoring of all technical programmes and data amendment. In order to implement the information modelling to design manage-ment, it is necessary to establish interaction between all the design participants by means of a special knowledge library represented by a catalog of standard solutions that can be used in subsequent pro-jects at variable component parameters. Software products used for the design of roads using infor-mation modelling were given. A 3D model of a motorway bridge containing the data on each element was presented, which allowed a spatial model of an engineering structure to be built. It was concluded that the use of information modelling of an object greatly facilitates the work of designers and con-struction workers, allowing for many advantages over previous means of developing road construction projects. This approach offers a combination and coordination of parts of the designed road object developed by different specialists and organisations.

The paper aims to analyze the historical-cultural potential of the Irkutsk city center, to consider the uniqueness and identity of its urban environment, as well as to explore the opportunities and experi-ences associated with the commercialization of historical buildings and relevant measures. The specif-ics of Irkutsk’s cultural heritage, its architectural landmarks, and tourist attractions are discussed in the study. In addition, the work examines the historical center of Irkutsk in terms of its architectural and space-planning features, along with the typology of buildings, comprising the historical and cultural heritage of varying significance. The concepts of identity and authenticity in Irkutsk’s development are defined. As part of the historical site development, it is proposed to commercialize cultural heritage (including wooden structures) through tourism (temporary accommodation), food service, and trade (gift shops, etc.). In order to attract attention to potentially suitable sites, it is suggested to develop new tourist routes connecting Irkutsk’s quarters that feature historical buildings preserved in their orig-inal state. The study presents a route plan proposed in a graduation thesis within the training program Reconstruction and Restoration of Architectural Heritage at the Irkutsk National Research Technical University (author – A. K. Mainovskaya; supervisor – A. N. Prokudin).

This paper addresses the characteristics of road design under permafrost conditions. Economic and mathematical calculations were used along with practical experience of “Svaybur” and “Gidrostroiengineering” companies, involved in road construction and maintenance for a long period. The prices for construction materials for economic and mathematical calculations were determined using the Integrated Construction Price Standards for Capital Construction Projects for Non-Production Uses. ICP 81-02-08-2017. Collection No. 08: Roads. The environmental requirements were based on the recommended practices developed by the Federal Agency “Rosavtodor”. The cost of maintaining and reconstructing a damaged section of road can exceed by several times the estimated construction cost of the whole section, as well as hinder the logistics and transport accessibility of the agricultural land. In some cases, the environment of the surrounding land may be adversely affected, since harmful contaminants that under normal conditions are bound by the top and bottom structures of the road are released into the soil due to its erosion. The paper examines the economic and environmental problems of designing roads connecting important logistics centres under insular permafrost and permafrost conditions. Here, the calculation of construction costs for road reinforced using screw piles if necessary to prevent the erosion of some road sections during spring floods or heavy precipitation is presented, along with a comparative analysis of construction costs for roads under insular permafrost and permafrost conditions.

In this work, a software package was developed in order to investigate the applicability of conductors having different cross-sections for installing internal electrical networks in individual households. A combination of general scientific methods, including circuit theory, numerical analysis and visualisation using MATLAB graphical editor, was used. The state of individual households in the Irkutsk region was analysed. It was confirmed that one of the most common causes of combustion associated with the construction of internal electrical networks of individual households involves unbalanced phase cur-rents, leading to additional heat losses, which give rise to fire hazards. A thermal calculation of the electric network functioning under normal operating conditions was carried out in order to obtain ex-pressions for determining the maximum permissible values of the neutral conductor current of the in-ternal electrical network of the house. These algorithms and programs were used to tabulate the limit values of the zero sequence currents for different cross-sections of the conductor material and tem-perature ranges. The efficiency of using balanced/unbalanced converters to mitigate the negative ef-fects of unbalanced power consumption was demonstrated by a field test. It can be concluded that one of the most efficient ways to reduce fire hazards in individual houses involves balancing the operating modes of the internal electrical network. The obtained data may therefore be used by construction or-ganisations, as well as the Ministry of Emergency Situations of the Russian Federation, which monitors the fire safety of individual houses.

Due to the considerable costs involved in industrial wastewater treatment, the introduction of open (low-discharge) and closed water circulation systems is the most sensible way to prevent environmen-tal pollution at industrial companies. Since the level of circulating water treatment can be much lower than that required for discharge into a water body, the installation of closed water circulation systems can achieve both the economic and total effects of environmental protection. Despite the seemingly obvious advantages of this approach, it requires a serious feasibility analysis. The life cycle costs of a construction project can be estimated according to GOST R 58785-2019 Water Quality. Life Cycle Cost Estimation for Efficient Operation of Water Supply and Sanitation Systems and Facilities. However, at the initial (pre-project) stage, the analysis can be based on benchmarks. Large industrial companies make extensive use of foreign estimation methods. The paper presents the results of a feasibility analysis obtained using different methods to justify investments in the reconstruction of wa-ter treatment facilities at an oil refinery.
由于工业废水处理涉及相当大的成本，引入开式(低排放)和闭式水循环系统是工业公司防止环境污染的最明智的方法。由于循环水处理的水平可以远远低于排放到水体中的要求，因此安装闭式水循环系统可以实现经济和环境保护的总体效果。尽管这种方法似乎有明显的优点，但它需要进行认真的可行性分析。建筑项目的生命周期成本可根据GOST R 58785-2019《水质》进行估算。供水和卫生系统及设施有效运行的生命周期成本估算。然而，在初始(项目前)阶段，分析可以基于基准。大型工业公司广泛使用国外的估算方法。本文介绍了采用不同方法对某炼油厂水处理设施改造投资进行可行性分析的结果。

This article discusses approaches to forecasting the earthquake odds of a given intensity level. This problem is relevant for the earthquake-prone zone in the south of the Irkutsk region characterised by an estimated intensity of shaking of up to 9 points, where large, populated areas having developed industrial and civil construction are located. The intensity values for Irkutsk were obtained using the analysed data on the seismic activity of the Baikal and Transbaikalia regions in 1973–2020 by the equa-tion of the macroseismic field. The algorithm for predicting large and medium-sized earthquakes in-volves mathematical statistics and probability theory. A corresponding empirical distribution was derived on the basis of a sample of the maximum intensity values for the specified period in each year. The potential applicability of common distribution functions for describing the intensity distribution of seis-mic vibrations was considered. It was established that the normal distribution function provides the most accurate description of statistical data. It was concluded that, by using this function, it is possible to determine the high-intensity vibration odds that can lead to serious destruction, as well as their most probable annual peak intensity, which may allow for measures ensuring the resistance of load-bearing structures of buildings to background seismic impacts.

In this work, the anthropogenic influence on the water quality in Lake Baikal was evaluated, since Lake Baikal contains 19% of the total freshwater resources. The use of data on the water quality near the Listvyanka village allows the changes in the content of ammonia, sulphates, nitrates, iron, phosphates and other substances suspended in water to be monitored. The characteristics of collected water samples were compared to previously obtained data. The evaluation of sample quality involved various techniques, including photometry using spectrophotometers, "blue ribbon" filters and desiccators. The obtained results showed that some of the indicators, for example, the amounts of suspended solids, sulphates and nitrates, significantly exceed those obtained in 2016 and 2020. The comparative analysis of samples collected in different years indicated a significant deterioration in water quality over this period. This can be explained by the lack of funds for the development and reconstruction of water and wastewater treatment facilities, along with an unregulated touristic flow, requiring the appropriate walkways, routes and utility systems in order to reduce the anthropogenic impact on the waters of Lake Baikal.

Economic digitalization, along with the transition to a new technological paradigm, has given rise to an ongoing transformation in the Russian Federation, expanding the high-tech industry and driving inno-vation across a wide range of economic sectors. However, the digitization level in the development and construction sectors currently remains one of the lowest among industries, despite the fact that con-struction is involved in creating production capacity and contributes to the growth of fixed assets, which ensures expanded reproduction in the entire economy. Therefore, it is necessary to promote the implementation of digital and innovative technologies in the construction sector, as its digital trans-formation can produce a synergistic effect reducing project costs in general, as well as improving the competitiveness of construction organizations and strengthening their position in the market.
