Authors: Fedosov S V , Bakanov V O , Nikishov S N 
Published: September 2020

Abstract
The paper considers the demanded porous building materials, as well as the main stages of their production technology. The advantage of block foam glass as a porous building material compared to other building materials is shown, and the basic technologies for its preparation are considered. It is noted that the priority technology for the foam glass production is a two-stage powder production technology. A schematic diagram of the foam glass production according to the two-stage powder technology is presented, where the cycle of heat treatment of the raw mix for producing foam glass is noted and the sequential steps of the process are considered, in which the raw material charge is exposed to high temperature. The physical and chemical features of the phenomena inherent in the individual phases of the raw mixture transition from heating, foaming and annealing to the finished material (foam glass) are analyzed. Fragmentation of the scientific ideas about the foam glass heat treatment process is noted; it hinders the adequate and optimal technological modes’ development for the foam glass production, which directly affect its further cost. The necessity of developing a general methodological approach to the study and modeling of high-temperature maintenance regimes of the raw material mixture TT for producing foam glass, the creation of rational technological approaches to the producing block foam glass process as a part of its production concept, the identification and study of the TT high-temperature maintenance regimes laws with such models and predicting the final operational properties of the finished material are emphasized.

Development of an algorithm for creating an insolation solution for a building within the construction area
Authors: Epifanov R P , Shilova L A 
Published: September 2020

Abstract
The work is devoted to the issues related to the development of the insolation solution for the building within the construction area. It is worth noting that these aspects are regulated normatively in most of the countries. The paper presents one of the possible approaches to the development of a script that makes it possible to automate the process of developing an insolation solution for a building in the constructionarea redistribution according to the criterion of the insolation duration. The introduction of this algorithm in urban planning practice will give the architect a tool that will allow, at the initial conceptual stage of designing a new building, to find the optimal shape and location for the building from the point of view of the insolation duration, as well as to obtain a parameterized BIM model of the building, to create the apartments’ layout, providing the conditions comfortable for the people to live, or during the additional calculations of the “passive house” project development. At the same time, there is a significant reduction in time and labor costs.

Authors: Shchutsky V L , Nasevich A S , Holodnyak M G , Blyagoz A M 
Published: September 2020

Abstract
A numerical experiment was conducted to study the effect on the restrictions’ cylindrical supports design strength on the crack opening and ultimate strains’ width. The analysis of the effect on the cylindrical supports’ fracture toughness and deformability of the relationship between the prestressed and total reinforcement areas (Asp/As,tot). The research results showed that the dependence of the crack opening width on the ratio Asp/As,tot for all cylindrical racks types is close to linear. The reinforcement coefficient s, tot % does not affect the nature of this relationship. The increase in the torque proportion from the vertical loads Mv/M leads to a significant increase in the crack opening width. The greatest influence on the cylindrical racks’ deflections has the prestressed reinforcement content (Asp/As,tot). In this case, the total reinforcement coefficient practically does not affect the type of function fpr=f(Asp/As,tot).

Geotechnical solutions for high-rise construction in the areas with significant elevation
Authors: Marinichev M B 
Published: September 2020

Abstract
The high attractiveness of the Black Sea coast in the Russian Federation, the ongoing work to create a world-class resort infrastructure lead to the need for the high-rise buildings’ construction and other heavy structures on steep grades that characterize most of the coastal strip. In such cases, they try to find the solutions that do not lead to a significant amount of earthwork when deepening the required number of floors under the stain of a high-rise building. However, with a large steepness of the relief, the excavation volume is always significant. Excavation during the engineering preparation of the territory and the development of deep pits leads to a loss of the slopes’ stability and, consequently, to the complex foundations’ solutions, engineering protection and overhead structures.
The common data environment features from the building life cycle perspective
Authors: Losev K Yu 
Published: September 2020

Abstract
One of the conditions for informational support of the construction projects’ life cycle and, in particular, the capital construction projects is the organization of a common data environment or, as it is called abroad, the Common Data Environment. The common data environment, being an integral part of information modeling technologies in construction, is multilevel in nature. The article draws attention to the fact that the aforementioned research object at present is considered mainly from the standpoint of foreign national standards in the field of information modeling in construction, which considers the common data environment mainly at the level of electronic document management in daily work in the design and operation of buildings and structures. Modern domestic technologies for the organization of construction should necessarily consider buildings and structures in the context of their life cycle, and not the life path, as a sequential set of data state phases. This article discusses the common data environment features from the perspective of managing the buildings’ life cycle. Using the analytical method of similarity and the dialectical method to describe the qualitative change in the model at a new consideration level, it is hypothesized that when moving from the considering interactions within the life cycle stage to the level of interactions between the life cycle stages, the concept of “data” gives a way to the “knowledge” concept. And in order to provide a complete ontology of the buildings and structures’ “life cycle” concept, a model using knowledge share is proposed.

Authors: Furmanov D V , Klochko N N , Tyuremnov I S , Chabutkin E K 
Published: September 2020

Abstract
Cutting off the reinforced concrete piles’ column heads is an important technological operation in the pile foundation construction. High-quality reinforced concrete piles column heads cutting should be performed at a given mark, without cracking concrete below the cut level. At the same time, reinforcing rods of the pile together with concrete are not removed. The rational equipment design for cutting the reinforced concrete piles’ column heads is complicated by the lack of information on the required forces developing on the working body of the machine. The theoretical justification of these forces is not possible, due to the lack of appropriate guidelines. To this end, the article presents the experimental studies’ results to determine the loads on cutting elements when cutting a reinforced concrete pile of square cross section. The experimental work technique is described, the conclusions of the study are presented.

Published: September 2020

Abstract
Practical justification and decision-making in construction is a difficult task. The customers formulate the terms of reference, on the basis of which, using the methods of comparing the solution options, determining their priority based on the degree of influence of organizational, technological, technical, economic and other factors, the solution options are developed and, therefore, a construction management system is formed as a whole.
The development of the required action scenario is aimed at achieving the optimal end result. The decisive factor in this case is the final result of the functioning of the organizational and technical structure.
This approach is fundamental in the formation of the organizational - technological management system, considered as a subsystem in the general system of construction production. Decision making is carried out in order to achieve the optimal (or most rational) end result when choosing a reliable technical or organizational-technological option. The backbone decisive factor is the specific system’s outcome.

Authors: Hayrapetyan Ye H , Petrosyan H S , Sargsyan G A 
Published: September 2020

Abstract
The scheme of a high-precision laser rangefinder with a crystal light modulator, which has the ability to work both on the compensation and on the two-phase mode of the linear measurements modulating method, is considered. The two-phase method is implemented by introducing another electro-optical crystal EOC in the receiving path, rotated 90° relative to the first one around the optical Z axis. In this case, a second signal is formed in the optical channel of the light rangefinder, shifted relative to the first signal by 180°. The measurement of the residual phase cycle occurs when the periodically received signals are equal. A theoretical analysis of the proposed scheme is carried out and in this case it is shown that, the receiving points fixing sensitivity increases, leading to an increase in the accuracy of linear measurements in 3-4 times, estimated by the phase determination error value of mφ = 0.02-0.03 mm.

Abstract
Engineering and geological conditions of the reconstructed territories are the important city-regulating factors in the development of master plans and land use as well as the development rules. They should be taken into account both at the pre-investment stage, and at the stages of the construction projects conceptual and working designs’ development. Data on the exposure degree to hazardous engineering and geological processes make it possible to determine the reconstructed site investment attractiveness degree, choose an effective organizational and technological solution for the urban development reconstruction, and make predictive calculations of changes in the stress-strain state of the buildings and structures depending on changes in soil conditions, such as subsidence and physical and mechanical soil properties.

Authors: Dudnik A E , Samsonova N V , Tupoleva G K , Kushtin V I 
Published: September 2020

Abstract
The article provides the lateral refraction influence factors analysis during the active radar sensing. With the passage of radio waves, a change in the refractive index in the atmosphere affects the radar image geometry due to the radio waves refraction and an increase in the time of their propagation. These factors shift the image in the direction of increasing distance. The solution to the problems of determining the corrections due to the refraction influence in trigonometric leveling is considered. The simulations of the quantities involved in the process obtained by the joint geodetic and meteorological measurements are used. The practical examples show the features of the corrections’ calculation. The formulas for determining the change in the distance ΔRδ due to the curvature of the trajectory of radio waves are given. The analysis of the data presented in the article is based on the data from the studies conducted using different brands of devices. The given indicators are generalized.

Abstract
The research methods of mudflow hazardous areas in the North Caucasus region are determined by the indicators that are priority in the development and study of similar areas. Mudflows require constant updating of their development territories’ maps, as well as the various parameters used to predict the mudflow threats and develop the anti-mudflow measures. The authors of the article present the indicators, values and air regime temperature, amount, composition, intensity, and also the precipitation mode, as well as the size and intensity of the modern glaciation and snow cover melting, the territorial moisture content, the presence of small rivers with large channels slopes and their flood regime. The analysis of the proposed research methods, on the basis of reliable materials and collected as a result of the mudflow phenomena study in the mountainous territory in the Republic of Ingushetia, divides the areas into three categories of mudflow hazard, and presents a medium-scale map of the mudflow hazardous areas in the Republic of Ingushetia at a scale of 1: 500 000.
Methods for displaying data using web technologies for the Arctic region and the continental shelf
Authors: Kopylova N S 
Published: September 2020

Abstract
In this article we discuss the principles of geospatial data design, which underlie the methods of displaying information based on the projection methods for the Arctic region and the continental shelf, using various web technologies. Various cartographic services were stud-ied depending on their functionality, the software development geography, and the associated mathematical system basis. We assessed the metric capabilities of the main projections under-lying the mapping services and determined the search functionality and demonstration tasks that can be solved by means of similar information systems. It is pointed out that it is neces-sary to provide the analytical functions for services and geoportals, which is necessary for mapping tools in making decisions. The principle of increasing accuracy, unification, ease of use was supported by the development of the unified approach for choosing a projection, that is the Unified Isometric Cartographic Projection. The use of this projection will make it possible to approach the data design issue in a unified manner, which, on the whole, will increase the cartographic security of the region and will make it possible to solve the cartographic problems in the unified manner. The accurate evaluation of the data obtained on the basis of this projec-tion showed that the results can be within the two meters accuracy. Such metric parameters are sufficient to make the design decisions on the infrastructure facilities’ development in the Arctic region and the continental shelf. In order to improve and develop the geoportal “The Arctic Spatial Data Infrastructure” (Arctic SDI), the option of improving its mathematical basis is a promising direction. In addition, the use of the Unified Isometric Cartographic Projection in a GIS user environment will remove the issue of the complex search for the optimal projection. Regardless of the tasks of mapping, when choosing the element needed (GIS user environment, 2D and 3D mapping services, databases) that defines the web mapping technology, data de-signing according to the single principle will remove a number of technical issues and incon-veniences, bringing it closer to the best option.
