Decorative concrete refers to a special kind of concrete. Products made of decorative concrete must meet, in addition to the increased requirements for appearance, certain architectural expressiveness and also certain indicators for strength, durability, and environmental friendliness. In addition, one should strive to reduce the cost of both decorative concrete and products made of such concrete. The analysis is carried out, experimental researches of qualitative indicators of industrial man-caused wastes are also studied: carbide lime, fluoride, sludge-lignin, their material and chemical composition. The possibility of using the analyzed industrial wastes as raw materials for production of white and color cements is established. The physicomechanical properties of the obtained cements and decorative concretes on their basis are studied, the economic efficiency of the proposed technology is determined.
The article describes the causes enough active use of the mechanism of the mortgage in order to resolve housing issues. It emphasizes that the problem of formation and development of the property market and the use of such forms of financing investments in real estate as mortgage lending is one of the most urgent today. In this regard, using the experience of developed countries, conclusions about the prospects of development of legal institutions in our country. Consideration of a mortgage as an intangible resource has a high degree of relevance in terms of further regulating mortgage as a banking product, as well as selecting the direction of development of state policy in the field of residential construction.
BIM using is one of the most crucial and integral parts of building management. A complex BIM-model gives a precise picture of the project’s final cost and can be used as a tool of budget measurement. BIM provides an opportunity to calculate all material and instead of manual calculating, it will change project cost estimate automatically if something in the project changes. In addition, it improves project economy and reduces the rate of random mistakes while project documentation assembling. However, experts in the construction industry acknowledge that the challenges that design companies face today in the transition to BIM are becoming more and more urgent. The article is devoted to the formation of a comprehensive view of the information model by stages of the life cycle. Through the implementation of information technologies in the field of investment and construction projects, achievable main problems allow for a new level of digital processing. Based on project lifecycle management, possible solutions to the identified problem blocks are proposed and their effectiveness is evaluated. Taking into account these changes, it will be possible to maximize the effective use of information modeling technologies at all stages of the life cycle of an investment and construction project.
The world building sector is experiencing the global transformation stage. In this process, traditional methods of building and engineering are being refused. Innovative ways to manage investment projects are chosen. They refer to the intangible assets of the enterprise. In the Russian Federation, building digitalization is in its first phase. Nevertheless, the need for the integration of digital technologies is recognized by many brunch subjects and is approved on the state level. Many national projects and development strategies also endorse the course. The following problems caused massive engineering digitalization: the lack of needed information or its distortion that helps to decide on building investment realization, the growth of pressure due to reduced time, and price of projects’ realization. The trend of digitalization of the construction industry determines the need to develop the scientific and methodological basis of the management theory of the introduction of advanced technologies. The article represents characteristics and the main aspects of the Construction 4.0 concept in three directions: intellectual factory, modeling engineering, digitalization, and visualization. It also describes and highlights the main provisions in the implementation of such intangible assets as digital document management and the Internet of Things. It is proved that implementation of control and audit procedures based on intangible assets are parts of the information model of the project and digital platforms. This way, effective systematic investment initiatives’ realization can be provided on every building project control level.
A 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
