The article deals with issues of necessity of training and development of working staff for construction industry of Russian Federation for creation of competitive construction industry, meeting the high quality and efficiency standards, working in basis of modern financial and economic, technical and management mechanisms. One of the ways to solve this task of innovative development is modernization of architectural and building design, in particular implementation of BIM technology enabling making efficient decisions at all stages of building and structures life cycle – from investment concept till operation and even demolition. In relation to this the industry demands highly qualified workers and engineers (bachelor students) being able not only to get new knowledge but to use them for solving practical tasks of modern construction industry and market. The article present a concept of designing educational programme for training students with major 08.03.01 «Construction» (bachelor degree) focusing on systematized knowledge, skills and tools for training, in particular, through interconnection and continuity during course and diploma papers based on BIM technology.
The paper examines an issue of ensuring reliable power supply to construction facilities, proposes ways to reduce losses in distribution networks and improve power supply reliability. The primary focus is on increasing the transmission capability of power distribution networks and improving power supply reliability and safety of single-phase electricity consumers. Engineering and technical proposal belongs to the field of electrical engineering and in particular concerns power supply to single-phase consumers from three-phase networks, including construction industry consumers, and can be used in three-phase three-, four- and five-wives alternating current power distribution networks.
This article deals with the issues concerning the accidents relevant to the underground pipelines operation. These pipelines transport gas, oil and its derivatives. The statistical analysis results of accidents in underground pipelines operated in Russia, as well as the analysis of the explosion causes in underground pipelines and primarily gasified objects are provided. It is shown that stress corrosion arising as a result of the phenomenon of hydrogenation is the most dangerous for large-diameter gas pipelines. The author proposes the justified and protected by RF patents new engineering solutions for consideration. They are aimed at improving resistance of steel structures against corrosion. Also a method of increasing the hardness, strength and wear resistance of steel parts surfaces by rapid cementation due to saturation of the carbon steel surfaces; a steel alloying method using aluminum to obtain diffusion coatings; and a method of applying a corrosion resistant and stable to acids and alkalis coating on the steel surface are presented. Proposed new technologies are accompanied by an explanation of the physical and chemical processes occurring in steel. The experimental results confirmed the validity of those decisions.
Nondestructive optical methods for measuring of the «thick» films thickness of the order of 0,001-1,00 mm are analyzed. It is shown that using the laser beam radiation and modern optical and electronic schemes possible to decrease the time of single measurement to 1ms and less at the measuring frequency of 10-50 hz. The possibility of measuring thickness and spreading coefficient and evaporation kinetics of liquid films is demonstrated. A new computer method of the data processing aimed to determine the film thickness from the angle dependence of the laser beam reflection coefficient by the film is offered. The offered procedure and the experimental technique realizing it permits to decrease the thickness determination uncertainty to the order of ten.
