Polymer composite materials: application in the construction of frame-attached shafts of elevators
The possibility of replacing traditional structural materials with polymer composite in the construction and reconstruction of elevator shafts of frame-attached structural solutions has discussed. The experience of using polymer composite materials and traditional materials (steel, aluminum, wood) is investigated as a comparison of their technical characteristics, advantages and disadvantages are given. The purpose of this article is to justify the use of fiberglass-based composite materials in the manufacture of structures and roofs of frame-mounted elevator shafts by comparing the characteristics of polymer composite materials and traditionally used structural materials. In the course of the study, it was found that polymer composite materials based on fiberglass has clear advantages over traditional materials, it is lighter, stronger, more resistant to atmospheric influences, it conducts heat poorly, does not pass water, and fireproof, which confirms the relevance of the chosen research topic.

HVAC design in Autodesk Revit using Dynamo
Explores the possibility of automating the design of a VK section in Autodesk Revit using Dynamo. It shows which regulatory documents are applied at the state level for the application of BIM technology. The logic of the work of visual programming Dynamo is briefly described. Two scripts are proposed for automating the design and execution of design and working documentation for the VK section. The first script shows the calculation of the sewage system in Autodesk Revit using Dynamo according to current standards. The second script shows the automation of the workflow during the design of the HVAC, or rather, the automatic receipt of a designed axonometric system.

Trial tests of domestically produced composite supports in St. Petersburg
Technological progress and the emergence of new materials help people develop innovative solutions to meet the challenges of the time. Currently, a line of lighting supports made of polymer composite materials and new production technologies of such products are being actively developed. This is being done so that physical and mechanical characteristics of composite supports could be improved in order to increase their advantages over reinforced concrete and metal supports, as well as to expand the territorial area of use of such supports in various climatic zones of the Russian Federation. This article discusses a trial test of a support made of polymer composite materials in the city of St. Petersburg. The purpose of this study is to determine the characteristics of the composite support, the possibility of its improvement, and the establishment of the possibility of its further use under the overhead power line. In this study, methods of observation and analysis of the results were used. As a conclusion, it can be said that the physical and mechanical characteristics of the mounted support are in full compliance with the stated requirements for composite supports installed in the city of St. Petersburg. In addition, this support satisfies climatic conditions which is important for the entire period of its operation. According to the review of St. Petersburg State Unitary Enterprise “Lensvet”, it can be concluded that the use of this support made of polymer composite materials is only possible with a combined installation with reinforced supports on small streets, alleys and quarters. This support is generally approved by St. Petersburg State Budgetary Organization "Lensvet" and recommended for operation in the city of St. Petersburg.

BIM by using Revit API and Dynamo. A review
Ways of automation of work with Autodesk Revit software package are considered. The user can automate complex or repetitive operations in BIM software. It is possible to create plugins by coding for working with the Revit API and visual programming in the Dynamo module. Tasks for the formation and export of databases for interaction with sensors and electric motors can be realized through Arduino controllers.

Artificial Materials in Seepage-Control Structures of Embankment Dams: A Review
Introduction. The urgent task of hydraulic engineering as a science is to search for more sophisticated, effective, and safe structures of embankment dams. Wide possibilities in this are presented by the use of artificial materials and structures made of them. To estimate the perspectives of their use, a historical survey was carried out on experience gained in the construction and operation of embankment dams with seepage-control structures (SCS) made of artificial materials. Materials and methods. For the survey the different sources, both modern and those of the past years, were used. There were analyzed SCS which were used in bodies and foundations of embankment dams since the start of the XX-th century. Results. The historical survey showed that over the last 50-70 years significant progress took place in the development of SCS made of artificial materials. First of all, there were used the new types of SCS made of new materials: asphalt-concrete and geosynthetics. Secondly, the new methodologies have been introduced in the construction practice by arranging SCS made of materials based on cement in dam foundations. The experience showed that these methodologies were also used for arranging SCS in dam bodies. Conclusions. In the future, there may be expected further extension in the scope of using artificial materials for the construction of embankment dam SCS. At that, the leading role among artificial materials is played by the materials based on cement (concrete, clay-cement concrete, soil-cement mixes, etc.). At the construction of ultra-high dams, these materials do not have any alternatives. Nevertheless, the most perspective way in improving structural designs of embankment dams SCS is a combination of different artificial materials (cement-containing and other materials), as well as the use of combined SCS.
