Abstract. Nowadays, almost none of the fields of human activity can do without supply chain management. In addition, implementation of one in construction companies contributes to major economic benefits. The article considers the application feasibility of blockchain in logistics of construction materials through the usage of RFID technology. An example of introduction to the process of manufacturing and delivery of ready-mixed concrete is given. The main advantages, shortcomings, perspectives, as well as difficulties arising in the implementation of blockchain technology in the construction industry are described. Special attention is paid to the applicability of these technologies.
Abstract. The process and methodology of the survey of basements rarely mentioned in the various construction rules and regulations. Basically describes the procedure of conducting a detailed survey of some of the individual elements. These surveys are fundamental in nature, include a large number of estimates and require significant financial and time costs. Usually the purpose of these surveys is to check the state of the building as a whole, it's safe operation or before starting of reconstruction. In the process of selecting areas of investment activity such large-scale survey is not possible. Needed a quick and inexpensive method intended for decision about investment in a particular object. At the same time, the survey should cover all the elements of the basement significantly affect the cost of reconstruction of the basement associated with his penetration. The article presents the general conception of conducting a rapid survey. The described methods and technologies applicable to the examination for the purpose of making decisions about investments in reconstruction of a basement level rooms. The composition of the works and their sequence. A comparison of the advantages and disadvantages of different methods. The practical examples. Scheme of conducting a rapid survey of the basement. The article analyzes the materials used in the construction of historic buildings in St. Petersburg.
To understand the importance of implementing energy-saving technologies in educational buildings, it is necessary to assess current energy consumption. The main goal of the article is to show the level of energy consumption of educational buildings in Russia. The main method of the study is to collect information from various sources and to analyze it in order to identify the factors that have the greatest impact on the volume of energy consumption. The collected information for Federal districts is compared with each other, and the average data for Russia is compared with figures for similar buildings in the European Union and North America. A comparison of the resulting data for the Federal districts of Russia shows that climate is one of the most important factors affecting energy consumption. As a result, according to different estimates, the total energy consumption in educational buildings is from 240 to 400 kWh/m2. It is one of the highest in comparison with developed countries of the European Union and North America.
The main reasons for the high energy consumption of residential multi-apartment buildings in Russia are the lack of motivation of developers in the construction and equipment of new buildings with a high energy efficiency class, as well as the insufficient number of energy metering devices. The main solution to the problem may be state support for energy-efficient technologies, compensation for excessive costs of the developer.
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.
