This work is important to study the creative heritage of Le Corbuier as one of the key architects of the 20th century, whose urban planning ideas had a significant impact on the development of modern urbanism. Of particular interest is his activity in India, where he implemented his theoretical concepts in the Chandigarh city project (1950-1960).

Purpose: The aim of this work is to analyze architectural and urban planning solutions of Le Corbusier, incorporated into the Chandigarh project, including his socio-political and aesthetic concepts, as well as their influence on the formation of modern urban planning.

Research findings: The main socio-political and architectural design concepts of Charles-Edouard, are identified. They are incorporated in the general scheme of the master plan, solutions for pedestrian and transport networks, garden and park areas and architectural solutions for the administrative center. The Chandigarh project demonstrates a unique syn-thesis of Western and Eastern modernist ideas, making it an important object of study in the history of architecture and urban planning.

The study of religious building architecture in the small historical town Yuryevets is conditioned by a threat of disappearance of its original appearance.

Purpose: Analysis of the adaptation of the capital's architectural tendency to local conditions in the temple architecture of the small historical town Yurievets at the turn of the 18–19th centuries, revealing the role of state standardization in the formation of a unified image of Russian cities.

Methodology/approach: According to the architectural and stylistic analyses of religious buildings, they are classified by architectural styles. The analysis of architectural solutions of objects built with a focus on the canons of "exemplary" architecture, allows identifying generally accepted stylistic principles.

Research findings: The development stages are shown for masonry construction in Yuryevets. The influence of provincial architects (N.I. Metlin, P.I. Fursov) on the synthesis of classicism with regional peculiarities is shown. Architectural styles of the key objects are analyzed, namely the combination of Baroque elements with the conciseness of classicism, the dominance of symmetry and functionality. It is proved that temples are visual dominants, subordinated to the principles of ordered layout.

Value: Classicism in the Yurievets architecture is an instrument of imperial cultural unification, suppressing local diversity in favor of standardization. Architectural solutions reflect the ideology of centralization, while preserving regional identity through the adaptation of capital’s projects. It is shown that preserved objects require restoration, as they are carriers of historical memory and unique synthesis of styles.

The relevance of research is determined by the insufficient study of historical industrial facilities preserved in the cities of the former Yenisei province – Krasnoyarsk and Achinsk, which is an obstacle in establishing their architectural and urban values and subsequent preservation. The loss of these facilities leads to a disappearance of a valuable element of the historical memory of the industrial development of the region.

Purpose: Identification of industrial buildings built by merchants, the analysis of their historical, architectural and urban values.

Methodology: Bibliographic documents, historical-archival and field research based on methods of historical-architectural, retrospective, cartographic and iconographic analyses.

Research findings: Preserved industrial buildings belonging to local merchants are identified in the cities of Krasnoyarsk and Achinsk and their suburbs: the glass factory near Krasnoyarsk, tanneries and breweries in the city of Achinsk. The technical condition of these facilities is different: the glass factory is destroyed, and the brewery and tannery facilities are in a limited working condition. The risk of loss of historical buildings is high. It is therefore required to take early measures to study buildings, recognize their value and preserve.

The contemporary perspective on wooden architecture requires not only an innovative approach to design, but also careful attention to its historical and cultural heritage. In the context of globalization, the preservation and reproduction of an ecologically favorable living environment for people becomes particularly relevant, which is impossible without considering the traditions and specific characteristics of the region. One of the main directions of this research is the Russian architectural style in Western Siberia cities late in the 19th and early 20th centuries. This topic is of particular importance, as it helps to understand how the diversity and richness of the Russian culture can be utilized to create a comfortable living environment.

Purpose: Identification of the Russian architectural style features in the wooden architecture of Western Siberia and its role in prerequisites for the modern use of wooden architecture. This allows for a deeper understanding of the relationship between all-Russian trends and regional specifics of wooden construction.

Methodology: The historical-architectural analysis, comparative analysis of design solutions and their implementation. Materials from project albums, archival documents, and visual analysis of preserved architectural monuments were used.

Research findings: It is shown that architects in Western Siberia creatively interpret all-Russian ideas, combining principles of modernism, eclecticism, and national-romantic traditions. This allows them to create a unique architectural identity for the region, where folk elements coexist with contemporary artistic solutions.

In the construction industry, building information modeling (BIM) is now the concept developing the fastest both globally and in Myanmar. By increasing the process productivity, efficiency, collaboration, and functionality, BIM enhances project planning and management, and it is progressively taking over as the norm for building projects in many nations. In recent years, Myanmar has begun to adopt the BIM technology. As an alternative to traditional building design and construction, this technology is still being investigated and considered in Myanmar. The BIM technology implementation as a requirement in public works contracts, raises significant issues and challenges. To accommodate the expanding population, the Myanmar government plans to build one million residences through smart city initiatives by 2030, and it intends to use BIM for this purpose. Nonetheless, there are a lot of misconceptions about this technology in Myanmar's construction industry, as some participants in the process lack experience, and its application is extremely cautious.

Purpose: Examining the present and prospective applications of the BIM technology in Myanmar's construction industry. The current condition and developments of BIM implementation in Myanmar's construction industry are briefly reviewed.

Research findings: The developed is the preliminary design of the infrastructure project utilizing BIM modeling tools for seamless design integration, efficient workflow, and precise structural analysis. The results underscore the BIM effectiveness in optimizing design processes while ensuring compliance with safety standards, and BIM's ability to integrate multidisciplinary tasks minimized design errors and improved overall project accuracy.

Practical implications: Recommendations are provided for the future prospects of the BIM implementation in Myanmar.

In the Russian Federation, there is a growing number of tank batteries requiring major repairs to outdoor structures. Insufficient regulatory framework for design and construction of such structures leads to the need to apply standards for the design of anti-filtration screens of landfills for toxic waste disposal, which significantly reduces the efficiency of design and construction, without guaranteeing sufficient reliability.

At the design stage of outdoor structures, it is necessary to take into account various loads. The analysis of Russian and foreign studies of structural solutions for open-air tank batteries shows insufficient development of snow load calculation methods that take into account the specifics of snow deposition at sites, especially in the northern regions of the Russian Federation. The lack of adequate assessment of this factor in combination with other loads (e.g., a spill of petroleum products) can lead to uneven deformation of the load-bearing structural element and potentially dangerous consequences, including environmental risks. This determines the relevance of the study.

Purpose: Verification of the methodology for choosing a constructive solution for open areas of tank batteries in the city of Salekhard, the thickness determination of the bearing element and feasibility study of the chosen site design.

Methodology: The integrated approach, determination of the total load on the construction of open areas, taking into account the layout of reservoirs within the park.

Research findings: The method of choosing rational constructive solutions is proposed for open areas of tank batteries. Based on this method, determined are the thickness of the bearing element, the labor intensity and cost of implementation of the constructive solution of the open areas of tank batteries with regard to different tank layout in Salekhard.

Reliability and accuracy of weighing a moving vehicle by automatic weight-in-motion (WIM) control systems depend on transport and trafficway performance. The experience in using WIM control systems on regional roads shows significant shortcomings in weighing accuracy due to low requirements for smoothness and structural strength of pavement in places of their location. Road irregularities cause additional dynamic loads on the road pavement and weighing sensors. The formation of ruts provokes lateral vibration of trucks, which is critically unacceptable in the area of WIM control system points and reduces the reliability of weighing results. The data analysis of violations registered in the Volgograd Region shows that about 10 % of trucks moving on regional highways exceed the permissible weight by 20 %. This leads to accelerated wear of the road pavement and defect formation.

Purpose: Substantiation of requirements for road pavements at WIM control system points and on approaches to them with regard to operation of the weighing equipment.

Methodology/approach: The analysis of actual conditions of the road pavement, assessment of the live load on the weight sensors, calculation of the minimum permissible values of the elastic modulus, rut depth and longitudinal evenness. Investigations are carried out with respect to sensor specifications and requirements for their operational safety.

Research findings: The maximum rut depth, elastic modulus of the road surface are substantiated, and requirements are presented for the permissible longitudinal evenness at WIM control system points and on adjacent road sections.

In the conditions of limited funding there is an increasing need to improve the winter maintenance system of the regional road network, especially the appropriate distribution of resources.

Research findings: A solution is proposed for the problem of sound management of material and technical resources of a contractor using the developed analytical priority resource system in winter on the regional road network on territories of municipal centers.

The article is devoted to theoretical and experimental studies of the impact parameters of truck wheels on road pavements. Modern systems of air temperature, tire pressure, and axle load monitoring are analyzed and selected. Monitoring of these parameters is carried out during the truck motion on roads at various speed and in different climatic conditions. Changes in the tire temperature and pressure are identified depending on operating conditions. A comparison is made between the actual and calculated internal tire pressure. It is found that the experimentally obtained internal tire pressure significantly exceeds that used in the pavement design. Further research aims at improving the pavement design methodology.

Purpose: The aim is to analyze and experimentally evaluate the impact load of truck wheels on the road surface to clarify the calculated pressure, contact patch size and temperature dependencies.

Methodology: The analysis of modern systems for monitoring changes in air temperature, tire pressure and axle loads, full-scale experiments at various speed and in different climatic conditions. The above parameters are monitored while a truck moves on roads.

Research findings: Temperature and tire pressure changes are identified depending on operating conditions. The internal tire pressure is compared to calculated ones. It is shown that the traditional approach, which assumes constant internal tire pressure, does not correspond to real driving conditions. It is found that actual values of internal tire pressure significantly exceed the calculated values used in the road pavement design.

Value: Research fields are proposed to improve the methodology for calculating road pavements, taking into account actual parameters of the live load.

In urbanized areas of the Russian Federation, the infrastructure of snow landfills does not meet modern environmental, engineering, and economic standards. This fact makes it necessary to carry out a comprehensive modernization of these facilities. The relevance of this study is determined by the problems associated with the utilization of snow masses, as well as the significant disadvantages of existing landfill complexes. The development of upgraded landfills that meet the requirements of sustainable development and environmental safety is a significant scientific task that requires a detailed analysis and systematic approach.

This paper analyzes the problems of snow polygons existing on the territory of the Russian Federation and the consequences of their absence, their current state, and identifies shortcomings in their functioning.

Based on the data obtained, an upgraded version of the snow landfill with an asphalt concrete surface is proposed, provided with a cleaning system that avoids harmful substances and solid waste from melting snow masses into the soil and removing the introduced water from the base and the earthbed under the site.

The proposed upgraded version of the snow training ground was put into operation in Tyumen and is successfully operating.

In Presidential Decree No. 309 of the Russian Federation, approved on 7 May 2024, “On the National Development Goals of the Russian Federation for the Period until 2030 and the Prospect until 2036”, the President decides to establish targets and objectives, the achieve- ment of which must demonstrate the achievement of the comfortable and safe living environment. According to the document, by 2030 the share of roads that meet regulatory requirements should be at least 85 % for federal roads and major urban agglomerations, at least 85 % for the backbone road network, at least 60 % for regional or inter-municipal roads. However, for Western Siberia, there are risks of not achieving the established indicators due to insufficient consid- eration of heaving properties of subgrade soils. Changes to GOST 28622–2012 introduced in 2022 and the emergence of the new instrumentation base for assessing the degree of soil heaving necessitate a comparison of the results obtained by different equipment.

Purpose: The analysis of laboratory test results of soil heaving on installations of various design to assess the feasibility of combining them into a single general set.

Methodology: Comparative tests on devices of different design, methods of mathematical statistics for processing and comparing the obtained results.

Research findings: Significant differences in the test results obtained on different installations are demonstrated. It is shown that combining data obtained on different installations into a single general population to identify new relationships and patterns is inappropriate.
