Identification of development drivers of using “green” technologies in investment and construction projects of the Russian Federation
Authors: Peshkov A V 
Published: May 2021

AbstractA high level of energy consumption per GDP unit is typical for the territories of the Russian Federation. Technical wear and tear and obsolescence of technological and energetic equipment, high energy losses in buildings and structures are the main reasons that caused a high level of energy intensity of GDP. Rapid population growth and competition for limited resources have further increased the need to design and construct buildings using sustainable construction technologies. These buildings must be able to maintain quality of life and ultimately ensure longterm human survival. The construction industry plays an important role in preserving the environment through the rational use of resources and assets that require the immediate massive implementation of the principles and methods of sustainable construction. One of the components of the principles of sustainable construction is the use of “green” technologies in construction projects, reconstruction, and overhaul of structures. The Russian Federation has a huge potential in reducing the negative impact of the construction industry on the environment and the social sphere. That is why it is very important to develop methodological foundations which are conducive to the successful development of the so-called “green” construction market in all regions of the country. Therefore, it is necessary to identify the main constraints to the development of “green” technologies. This article is intended to identify obstacles to the implementation of the “green” construction from the general contractors’ point of view. The article identifies points of growth based on the identified problem areas. Growth points are needed to form further positive dynamics of construction volumes using “green” technologies. The identified development drivers will contribute to the expansion of demand and provide a multiplicative stimulating effect on related sectors of the investment and construction complex soon.

Published: May 2021

AbstractThe goal of this study was to optimize the technological process of works related to concreting in the winter period to ensure a high-quality overhaul process. Demonstrate by laboratory research the effect of using various methods of concreting on the quality of work performed. To study thermodynamic processes, a stand is used that monitors the temperature fields in the volume of the concrete mixture, as well as heating elements with a positive coefficient of thermal resistance. The distribution of temperature fields in the volume of concrete mixture was studied depending on applied methods of concreting. Studies have shown that in order to reduce the time of repair work in the winter period, it is necessary to heat up the base of structures, and apply additional heating for critical structures. The experiments have shown that the use of heating elements with a positive coefficient of resistance when carrying out concrete work in the winter period of time will provide a high-quality performance of repair and construction work.

Published: May 2021

Abstract
The article examines the ideological influence (party leadership) in the building industry in the post-war period using the material of Siberia. The review reveals a characterization of the role of the Communist Party in the USSR. Further, the applied methodology is disclosed and the historiographic situation is characterized. Playing a leading role through the system of state and public organizations, the Communist Party in the USSR united and directed their efforts towards a common goal, acting by methods of organizational and ideological educational work. Party monopoly in the interpretation of economic processes as a rule was more important than production realities. A detailed study of the Soviet experience is necessary to preserve historical memory and learn lessons from the pages of our history. The relationship between political events and economic indicators is traced.
Features of civil proceedings on capital facilities
Authors: Zhuravlev E G 
Published: May 2021

AbstractIn civil proceedings, cases on classification of facilities into capital or non-capital ones are often heard. As a rule, in these cases, forensic construction and technical examinations are appointed by a judge. The main technical signs of capital facilities are an inextricable ground connection, available utilities, durability and reliability, movability, and demountable nature. The current Russian legislation needs to be amended and supplemented. It is necessary to define the concepts of strong ground connection and disproportionate damage to the purpose in order to correctly classify construction objects.
Specifics of wooden housing construction in Irkutsk
Authors: Rudykh L G 
Published: May 2021

Abstract
Irkutsk is the capital of Eastern Siberia and it can also be called the capital of wooden architecture. Many wooden buildings are of unique cultural and artistic value. Special originality and uniqueness of the city of Irkutsk gives the distinctive wooden architecture. The uniqueness and uniqueness of modern Irkutsk is that to this day it has preserved wooden houses that have come down to us almost unchanged. For a long time, different styles were used in the construction of wooden houses: baroque, classicism, modernism, art nouveau, eclecticism. An interesting fact is that the listed architectural styles in Irkutsk have never been used in their pure form, and samples of the decor of wooden buildings were interpreted by Irkutsk masters independently, which led to the birth of the original original architecture. Some of these technologies are still popular today, for example, decor technologies: relief ornament; slash; overhead; oriental decor. The art of building from wood in Irkutsk has its own specifics, taking into account the nature of the material and construction techniques. The expressiveness of wooden architecture is achieved by simple geometric shapes, natural wood texture, such as pine, larch, oak, fir and others. Construction techniques are determined by socio-economic and climatic conditions. In Siberia, there have long been two structural systems of buildings – log and frame, which are still used today.

Published: May 2021

Abstract
The account of dependence of moisture conductivity coefficient, thermal conductivity coefficient and heat capacity on temperature and moisture is the main peculiarity of the new physico-mathematical model of combined heat and moisture transfer in walls of low-rise wooden insulated timber buildings. This study is aimed at refining and testing such model, including preliminary evaluation of influence of moisture transfer processes on moisture accumulation in insulated timber structures with connectors at low outside temperatures. The study provides approximation dependences that illustrate variation in thermal characteristics of wooden structures made of timber, plywood and insulation. The results of numerical simulation of heat and mass transfer processes occurring in a representative wall fragment made of high-strength profiled timber are given. Temperature and moisture fields are calculated in a selected inhomogeneous fragment. Maximum humidification in insulated profiled timber walls is located on the external surface of the wall. It is found that the use of additional internal longitudinal lamellae in timber with vertical connectors leads to significantly uneven moisture distribution. Based on the calculation results one may conclude that the wall fragment under study has no areas where free moisture can be possibly accumulated.

Abstract
Today, even taking into account the rapid progress, one of the most important problems of any organization is the loss of income due to violations of labor discipline of employees. The solution to this problem can be the use of specialized software and hardware products designed to monitor and control the actions of personnel. The construction industry is the most lagging behind in the issue of automation of accounting for actually worked time due to the complexity and versatility of the processes taking place at the construction site. Failure to meet the construction deadline leads to the accrual of fines, reducing the income from the contract. In addition, objects that are not completed on time spoil the statistics of the construction organization and can reduce the likelihood of receiving a new order, and the absence The importance of the developed system lies in the fact that the information that this system will analyze will allow: discipline, calculate wages for the actual time worked and the amount of work performed, receive factual data on many problems and exceptional situations that arise during the implementation of projects.

Published: May 2021

Abstract
The article considers the problems of enterprises using baromembrane water treatment technologies in technological processes. At present, the basic operational data required to monitor the operation of the equipment and to further analyze the efficiency of its use are collected manually, with the collected parameters recorded in the paper operational statements. To avoid the introduction of erroneous indicators and reduce the labor intensity of the process during manual data collection, it is proposed to develop and implement a software product that allows normalizing the parameters of the reverse osmosis installation by recalculating operational indicators taking into account correction factors. In addition, the developed software product allows you to build graphical dependencies of normalized performance, selectivity and pressure differences of reverse osmosis systems. In the future, the program code of the electronic program tracks critical deviations of the calculated normalized parameters and signals to the user the need for corrective actions. The article presents a study of the operation of the membrane plant for the life cycle of membrane elements (3 years). The results of the study of these processes with the help of the developed software product showed a high efficiency of identifying possible problems during the operation of reverse osmosis plants in the early stages, such as the formation of deposits and contaminants on membrane elements, which will significantly increase the service life of membrane elements in various industries.

Published: May 2021

Abstract
Russia is entering a new technological order. The transfer to the digital technological format will raise the national economy to a new level in the innovative orientation of all companies. At the same time, the digital economy is based on digital transformations of all industries. The implementation of digital technologies into the construction industry is an irreversible process. The digitization can radically transform the construction industry and create new opportunities for its development. Digital construction is based on the use of information and communication technologies for more efficient and high-quality execution of construction and installation works and management of capital construction facilities. Many new information technologies offer numerous opportunities for construction companies. However, to consolidate the position of a single digital space in the construction industry, it is necessary to develop new approaches to the interaction of all participants in the investment and construction activities.

Authors: Balabanov V B , Putsenko K N , Epritskaya N K 
Published: May 2021

Abstract
Concrete is one of the most common construction materials. Strength and frost resistance are the main and most important properties of concrete. Frost resistance of concrete is very important for buildings and constructions erected in Russia, since many regions are characterized by harsh climate conditions. These climatic conditions include: low temperatures, fluctuations of both temperatures and humidity. As a result, concrete saturates with water, and after repeated alternating freezing and thawing, concrete may start damage. The idea of my scientific investigation is to develop a new technology of manufacture of the concrete possessing improved technical and operational characteristics, first of all, frost resistance. Within the frames of the present investigation, we studied the available experience of applying silica fume and polymers in concretes in the capacity of modifying additives used to elevate frost resistance. An optimal ratio of the additives was found, and the optimum composition of polymer concrete modified with silica fume was developed. Investigations bound up with determination of the principal physical and mechanical properties have been conducted.

Published: May 2021

AbstractThe article presents a comparative analysis of water absorption of non-autoclaved foam concretes based on microsilica and autoclaved aerated concretes based on fly ash. It is experimentally established that the water absorption by mass of foam concrete the grade D500 is 19.6 % higher than that of aerated concrete of the same grade. Open porosity, which is numerically equal to water absorption by volume, is also higher for non-autoclaved foam concrete by 30.1 %. Closed porosity for autoclaved aerated concretes based on fly ash the grade D500 is 53.9 % higher compared to non-autoclaved foam concrete of the same grade. The dependences of open and closed porosity of cellular concretes based on technogenic raw materials on their average density are experimentally derived. In the course of research, it was determined that water absorption, open and closed porosity of cellular concretes at the same average density depends on the type of aggregate and on the hardening conditions.

Published: May 2021

AbstractAlmost 150 thousand people live in the central ecological zone of Lake Baikal. However, there are no sewage treatment facilities that would meet the requirements for the discharge of treated effluents into Lake Baikal. The analysis has shown that there are no existing wastewater treatment technologies as applied to Lake Baikal. The work proposes to transfer treated wastewater to other watersheds. For these purposes, we have developed a methodology and methods for optimizing the parameters of pressure-gravity systems for the transportation of wastewater. For this, we have developed a general concept of wastewater disposal from the territory of the central ecological zone of Lake Baikal to other watersheds. We have given the examples and shown the economic efficiency of the proposed methods and programs.
