Urgency of the floor structures replacement is driven by the program of capital repair of the residential buildings adopted by the government and stipulates replacement of wood coverings by armored concrete floors that enable increase of stability, fire-resistance and cost effectiveness. Wood partitions and other elements of planning made of materials with low fire-resistance are also subject to replacement. It has been shown that the use of void formers allows reducing consumption of concrete, reinforcement, reduces duration of building and energy consumption. Thereby the stability and fire-resistance increase of the buildings under renovation is achieved. Solving these tasks is the objective of the represented work. It is worth noting that when renovating buildings the data about the use of not extractable void formers are absent. The technology development is an author’s initiative. The goal of the investigations consists in analyzing the works of the domestic and foreign scientists that make it possible to assess effectiveness of the technology when erecting buildings of cast in-situ reinforced concrete with the use of void formers. The submitted work has carried out the adaptation of the works performance technology in confined spaces of capital repair. Optimization of the void formers selection has been made, node points of the slabs’ resting on brick walls have been developed, the technology of dismantlement, form work, reinforcing, installation of void formers and concrete pouring has been developed. The complex of the works provides for obtainment of floor structures with the lesser consumption of concrete and reinforcement..

Soil Liquefaction is a phenomenon of loss of strength of the granural soil layers due to increased pore water stress caused by earthquake shocks. Soil liquefaction can cause material and life damage if occurs in the developed area. Kulon Progo Regency based on the Atlas of Liquefaction Susceptibility Zones in 2019, has high susceptibility zones, which has the potential for flow liquefaction, lateral spreading, vertical displacement, and sand boil. This study aims to assess the exposure and loss index in liquefaction hazard zone based on the characteristics of land use and social demographic. The exposure index is obtained from overlaying between susceptibility map and liquefaction exposure variables, when the loss assessment is done by simulating the losses in several earthquake moment magnitude scenarios. Study results show that high exposure surrounding the residential zone in the south of the Wates Urban Area and the construction location of the Yogyakarta International Airport. There are settlement areas potentially affected by lateral spreading in Glagah, Karangwuni, Banaran, and Karangsewu Villages. While the results of the loss assessment show that transport infrastructure and residential buildings are the most affected objects when liquefaction phenomena occur due to the earthquake. Managing the expansion of settlement area through zoning regulation and technical engineering approach is needed to reduce losses due to future liquefaction phenomenon.

The development of urban agglomerations as one of the most important urbanization processes in the modern world was considered. The economic expansion, as well as the increase in the motorization level in the middle of the 20th century, changed the vector of urban development from a vertical to a horizontal direction. This direction is also typical for the Belgorod region. The specificity of the development of the Belgorod suburbia is the massifs of individual residential buildings form a dense ring around the center of the region - Belgorod city. Statistical data that characterize the development of social infrastructure (general education and medical institutions), as well as transport infrastructure, were analyzed. It was revealed that in the emerging microdistricts of the suburbias, the transport, social and cultural infrastructure is not fully developed. It was shown that the reorganization of the transport infrastructure of the Belgorod suburbia should include some actions. One of them is the organization of transport interchange hubs as elements of transport infrastructure that can significantly change the current situation: to relieve roads, reduce car commuting, and provide people with the opportunity to comfortably transfer from one mode of transport to another. The organization of transport hubs will allow organizing a comfortable living environment for the population living in the agglomerated Belgorod suburban areas and reduce the load on the city's transport network.

Acoustic Load

Summary. Introduction: Traffic flows cause noise discomfort in 75-80 % of urban territories. Automobile and railway objects located near residential buildings generate indoor noise levels that exceed current standards by 5–30 dB. Approximately 20–25% of the Russian population live in areas of excessive traffic-related acoustic load. Despite the existing methods of acoustic load reduction in residential quarters, the number of complaints about high noise exposures in residential buildings keeps growing. Our objectives was to give a hygienic substantiation of an additional method of acoustic load reduction in residential premises based on the results of analyzing the level of acoustic discomfort. Materials and methods: Measurements, assessment and analysis of the noise level along automobile roads and railways and in the reverberation chamber were carried out in accordance with the current regulatory and technical documentation using a noise/vibration meter and spectrum analyzer “EKOFIZIKA-110A”. Data was processed using the Signal+/110 Utilities software. We studied characteristics of sound insulation of airborne noise with polyester shutters with fire retardant impregnation. Results: The results showed that high noise exposure levels in residential areas with transport infrastructure. Automobile traffic flows form an acoustic load in the range of 71–84 dBA, urban railway traffic flows (trams) – 61–80 dBA, and a train – 66–77 dBA. The excess of hygienic standards at night can reach 32 to 39 dBA. The material with the best sound insulation properties was selected showing an efficiency of 5 dBA. Conclusions: Acoustic discomfort is now registered in urban residential areas with developed automobile and railroad networks. Available methods of soundproofing and noise mitigation are not effective enough or may not be used in the current urban development situation to reduce the risk of negative reactions of the human body to excessive noise exposures in residential premises, especially at night. A 5 dBA acoustic load reduction can lower the risk of negative reactions of the human body to noise exposures.

In the article various variants of the decision of such acute problem, as shortage of parking places in system of a city infrastructure are considered. The necessity and expediency of constructing high-speed mechanized car parks for cars is caused by the acute problem of temporary and permanent storage of vehicles in the conditions of large cities, in places of intensive human flows such as the central part of the city, supermarkets, railway stations, shopping centers, as well as business centers and residential sector cities. To date, most of the real estate (residential buildings, hotels, offices, shopping and entertainment and multifunctional centers) are built with standard parking spaces. During the operation of such standard parking lots, the developer understands that the number of cars exceeds the number of parking spaces provided in the parking lot. The shortage of parking spaces and free parking areas significantly increases the importance of the construction and arrangement of multi-level parking lots. The system of high-altitude automatic parking lots offers a serious alternative to the generally accepted ideas about parking of vehicles [1].

Introduction. In the field of implementation of integrated programs of housing construction as a promising direction from the point of view of solution of the most important problems of modern development of the construction industry (intensive growth of urban areas, low quality and high cost of new housing, poor infrastructure), the key task has been set: rationale of the characteristics of the complex of construction sites taking into account interrelations between the number and characteristics of residential buildings and infrastructure facilities. Based on the results of the analysis of the relevant scientific literature, the conclusion was made that the existing tools are limited and fully take into account the key features of the implementation of integrated programs of housing construction. Relevance of research which objective is development of a method of substantiation of characteristics of a complex of construction sites is substantiated. Materials and methods. The organizational and process characteristics method of the complex of construction sites on the basis of linear fractional programming, which implies the determination of the optimal number of housing construction sites and infrastructure facilities in the context of different instances and categories by the criterion of maximizing the profitability index of the corresponding construction project was developed. The key elements of the developed method are optimization models, which are linear relatively unknown variables and therefore implemented using simplex method in modern software environments of optimization modeling. Results. The developed method is implemented on a practical example using Microsoft Excel software environment and the “Solution Finder” add-in. As a result of performance of corresponding calculation procedures, concrete values of quantity of sites and infrastructure facilities within the limits of the building project have been received. Conclusions. On the basis of adequate results obtained from the implementation of the proposed methodology on practical example, the conclusion was made about the high practical significance of the developed tool. The main shortcomings of the developed method are revealed, connected with the absence of consideration of factors of influence of features of a transport infrastructure and technological resources within the limits of construction procedure on characteristics of the project. In order to eliminate the identified shortcomings, it is planned to improve the methodology at further stages of the research.

Since the beginning of 2020, the "Nurly Zher" housing and communal development program for 2020-2025 came into force in Kazakhstan. Within the framework of this program there are tasks of capital repair and renovation of the housing stock. The passportization of the housing stock was adopted as one of the measures to solve this problem. At the same time there are some discrepancies in the statistical data between the Committee of Statistics of the Ministry of National Economy of the RK and Local Executive Authorities with a simultaneous increase in the volume of housing construction. This article examines the volume of residential buildings commissioned in Nur-Sultan depending on changes in the population of the city. It is assumed that as the number of people in the city will increase the volume of housing stock. To understand the volume of housing in Nur-Sultan in the period of the program "Nurly Zher" in the article gives a forecast increase in commissioned housing by 62% by 2025, compared with the value at the end of 2020. Based on the data obtained it is concluded that for a more effective solution to the problem of capital repair and renovation of housing stock an alternative approach or tool is needed.
