The article is devoted to the study of the interaction of the construction cluster participants, which determines the dynamics of the volumes and paces of construction in the region. The main subjects of this process are construction organizations and manufacturers of building materials. The main requirements of regional construction companies to suppliers of building materials are defined. The factors are revealed reflecting the dependence of the results of the construction companies' activities on the production and economic activities of the companies producing construction materials. Based on the available observations for 7 years, a statistical analysis of the samples was carried out and regression models of dynamics were constructed, the significance and adequacy of the obtained models were checked. The constructed mathematical models reflect the dependence of the volume of performed work in construction from the production indicators of manufacturers of building materials and supply organizations. The conducted research allows us to conclude that the most significant negative factors affecting the volume of work performed are the dynamics of prices for finished metal products and the dynamics of prices for the transmission and distribution of electricity.

The article is concerned with determining the main predictors of bankruptcy in construction organizations in the Russian Federation. Probabilistic prediction of bankruptcy is relevant for both individual companies and sectors of the national economy. Developed a long time ago, the existing bankruptcy prediction methods do not consider the industry specifics of organizations. The article investigates the mechanism for probabilistic prediction of bankruptcy based on logit models. Criteria affecting the bankruptcy probability were substantiated; a mathematical model was proposed to calculate the probability. The provided model was tested in a real company. Based on the sample of small and medium-sized construction companies, the author proposed a logit model reflecting the main factors affecting the financial state of construction companies in Russia and, therefore, the likelihood of their bankruptcy. Testing the model on the actual data from the construction enterprises showed its high predictive power. The study results allow predicting the bankruptcy in construction organizations by means of logit models.

Abstract Construction Industry indicates development of the country and it helps in the economic growth which adds productivity and quality of life of citizens. During the manufacturing and the construction processes, there is use and combustion of fossil fuels which results total 39% of total carbon footprint. So, studying carbon footprint for construction companies becomes very important. Many different studies are carried out with giving number of alternatives to reduce the amount of carbon footprint. However, this research is focused mainly on multi-storeyed residential building in renowned city in India, shows the carbon emissions produced by a construction activity right from the material production to the actual execution process. Different Greenhouse gases contributing carbon footprint were also studied & incorporated. Various activities accounting to emissions were listed and their carbon footprint value (in the form of Carbon Dioxide equivalent) was calculated by bottom-up method. The manufacturing of various construction materials and usage of electricity during execution phases of a building causes very bad impact on the environment. The greatest contributors of the carbon footprint are onsite electricity use and building materials manufacturing. Therefore, use of green concrete, renewable energy, prefabricated construction materials and low emission construction equipment & vehicles can help in reducing the values of Carbon Footprint by the construction industry.

Установлено, что на пути развития строительных организаций существуют проблемы, связанные с финансовыми рисками, а также необходимостью соблюдения экологических требований к строительным материалам и самому строительству. Цель исследования заключается в теоретическом обосновании степени влияния механизма саморегулирования на процесс снижения уровня экологических и финансовых рисков в строительных организациях, что является актуальной задачей. Доказано, что вопросы совершенствования механизма саморегулирования оказывают существенное влияние на динамику рисков в сторону их снижения. Административная реформа, которая начата в Российской Федерации, позволила сформировать институты саморегулирования, позволяющие существенно снижать уровень совокупных затрат в отрасли и уменьшать экологические и финансовые риски. Установлено, что саморегулируемые региональные организации (СРО) России получили дополнительные права в сфере осуществления контроля закупок строительных материалов, что позволит снизить уровень затрат и заставит строительные организации закупать материалы, прошедшие экологическую экспертизу. СРО наделили правом контролировать стандарты на процессы выполнения работ и утверждать квалификационные стандарты специалистов в области архитектурно-строительного проектирования. Предложен комплекс мер по совершенствованию взаимодействия саморегулируемых региональных организаций России с государственными органами и муниципалитетами в вопросах их активного участия в реализации политики государства в области градостроительства и внедрения механизма государственно-частного партнерства в формировании городской среды, а также ликвидации ветхого жилья. It is established that there are problems associated with financial risks, as well as the need to comply with environmental requirements for building materials and construction itself, on the way of development of construction organizations. The purpose of the study is to theoretically substantiate the level of influence of the self-regulation mechanism on the process of reducing the level of environmental and financial risks in construction organizations, which is an urgent task. It is proved that the issues of improving the self-regulation mechanism have a significant impact on the dynamics of risks in the direction of their reduction. The administrative reform initiated in the Russian Federation has allowed the formation of self-regulatory institutions that significantly reduce the level of total costs in the industry and reduce environmental and financial risks. It is established that self-regulating regional organizations of Russia have received additional rights in the field of control of procurement of construction materials, which will reduce the level of costs and force construction organizations to purchase materials that have passed environmental expertise. SRO was given the right to control the standards for the processes of work and approve the qualification standards of specialists in the field of architectural and construction design. A set of measures is proposed to improve the interaction of self-regulating regional organizations of Russia with state bodies and municipalities in matters of their active participation in the implementation of state policy in the field of urban planning and the introduction of a mechanism of public - private partnership in the formation of the urban environment, as well as the elimination of dilapidated housing.

The article actualizes the importance of the development of the construction materials industry in the Russian Federation from the point of view of the need to level the existing imbalances in the socio-economic development of the regions. The main trends, problems and prospects of development of the construction materials industry are analyzed on the materials of the Republic of Bashkortostan – one of the leading subjects of the Russian Federation. In the 1990–2000-ies of economic reform in the construction complex of the country were destroyed centralized management structures, deformed industry and spatial structure of the complex, violated the relationship between suppliers and consumers of building materials and structures, which led to the bankruptcy of most of the largest construction trusts, reducing the volume and pace of construction and installation work. In the Republic of Bashkortostan, the share of private construction companies has increased with a decrease in the share of state-owned enterprises and enterprises of mixed ownership. Due to the crisis situation of a number of Republican manufacturers of building materials, the volume of unfinished construction is growing, the needs of the region in construction materials and structures are not covered sufficiently. The results of the analysis of development of construction complex of the region and substantiates the need for structural and technological modernization of the industry of construction materials based on the structural transformation of the economy of the region, introduction of the latest scientific and technical achievements, advanced machinery and technological processes, effective structural changes and institutional reforms. Taking into account the advanced foreign and domestic experience (Moscow, Moscow region, St. Petersburg, Sverdlovsk, Voronezh, Kaluga, Lipetsk, Novosibirsk, Samara, Saratov regions and the Republic of Tatarstan), the priority directions and mechanisms of structural modernization of the construction materials industry of the Republic of Bashkortostan through the use of the cluster approach are scientifically justified.

Quality of material issues have been a significant source of concern since the dawn of recorded history. Building materials are essential and should be performed according to standard specifications because they cover around 60% of the project cost. Prior to project construction, specific codes, standards, and specifications should be available. Using all required materials does not guarantee a sound building appearance or function. Even with suitable materials, workmanship, and supervision, unexpected output can affect a building. Quality workmanship is a comprehensive approach to bolstering building durability, serviceability, and safety. The study evaluated Ambo University's building construction materials and quality. Convenience and quota sampling techniques were collected from all contractors and consultants involved in building construction via questionnaires and interviews. A comprehensive literature review identified 15 major factors affecting building construction materials quality and workmanship, and respondents ranked them in the order of importance. Defects in existing buildings and ongoing projects had observed due to non-compliance with construction materials and workmanship based on specifications and standards. The results indicated that Ambo University building has no defect free structure, including the degree and type of defects vary. A 94% of the studied buildings had moisture leakage, plastering defects, paint peeling, and cracks. Hence, the consultants and Ambo University project representatives should adhere with the standard specifications, and must exercise their profession according to the ethical code of conduct. All of these, it will play a vital role in the success of construction projects.

Introduction. The article deals with the main traditional outbuildings of the Mordvinians, reported on their functional purpose in economic activity. The forms and types of outbuildings, as well as the main building materials used by Mordvinians are described in details. Their significance in the religious and ceremonial life of the ethnic group is shown. Materials and Methods. The research is based on traditional methods of ethnographic science, such as field observation, survey and interviews, and a comprehensive approach. Among the methods of historical science comparative-historical, historical-genetic, problem-chronological, structural-system were used. Among the general scientific methods of research logical, descriptive, narrative, generalization, classification and systematization were involved. To achieve the results of the study, the materials collected by the authors in the course of field surveys conducted in the Mordovian villages were mainly used. Results and Discussion. Traditional outbuildings were of great importance in the economic activity of the Mordovian ethnic group. According to their functional purpose, they can be divided into the following groups: for livestock and poultry (stable, chicken coop, stable, kalda), sanitary and hygienic (bath), warehouse buildings for storage of food, utensils, firewood, animal feed (barn, cellar, woodshed, hayloft), for processing of grain (sheep, riga, mill). Depending on the welfare and financial capacity of the family, the number of outbuildings was different. As a rule, the wealthier families had more outbuildings than the less wealthier ones. The main building material for the construction of these buildings was wood. Conclusion. Thus, the traditional outbuildings of the Mordvinians occupied an important place in its economic activities. At the same time, each of them had its own purpose and performed certain functions. Some buildings, such as a bath and a barn, had not only economic purpose, but also were the venue for a number of prayers and ceremonies. It is now ordinarily they have banya (bath-house), outdoor courtyard with standing in different places sheds, barn and cellar.

Because the production of aggregates for mortar and concrete is no longer sustainable, many attempts have been made to replace natural aggregates (NA) with recycled aggregates (RA) sourced from factories, recycling centers, and human activities such as construction and demolition works (C&D). This article reviews papers concerning mortars with fine RA from C&D debris, and from the by-products of the manufacturing and recycling processes of building materials. A four-step methodology based on searching, screening, clustering, and summarizing was proposed. The clustering variables were the type of aggregate, mix design parameters, tested properties, patents, and availability on the market. The number and the type of the clustering variables of each paper were analysed and compared. The results showed that the mortars were mainly characterized through their physical and mechanical properties, whereas few durability and thermal analyses were carried out. Moreover, few fine RA were sourced from the production waste of construction materials. Finally, there were no patents or products available on the market. The outcomes presented in this paper underlined the research trends that are useful to improve the knowledge on the suitability of fine RA from building-related processes in mortars.
