Abstract: Testing frozen soils in the dynamic mode requires the use of special equipment designed specifically for these purposes. Using devices of the standard design in this case will lead to low-precision results. The first recommendations for the development of a domestic resonance column for frozen soils are given in the previous publication [1]. This article presents data from foreign colleagues on modifying a dynamic triaxial compression device for testing frozen soils. On the basis of foreign experience and taking into account the analysis of the dynamic properties of frozen soils [2], some recommendations for developing a dynamic stabilometer for frozen soils are proposed.

Keywords: frozen soils; dynamic properties; laboratory tests; dynamic triaxial compression; devices.

Abstract: The article considers a way of building retaining walls for the creation of deep foundation pits and large-diameter wells. This method involves the use of Russian serial drilling rigs of the PBU-1 and LBU-50 types, as well as the use of tracked mobile drilling rigs in tight urban conditions in the case of soft water-saturated sandy-clayey soils having quick-soil properties.

Keywords: foundation pit; large-diameter well; retaining wall; soft water-saturated sandy-clayey soils; quick-soil properties; borehole; narrow cut in ground; I-beam; concrete wall; metal reinforcement skeleton.

Abstract: In recent years, we have seen a steady increase in the volume of new road construction. Moreover, nowadays, the implementation of very ambitious and complex projects is beginning from an engineering-geological point of view, for example, the construction project of the new Dzhubga-Sochi high-speed highway. In order for such projects to be implemented on time and at the same time without increasing their cost, it is very important to perform high-quality engineering surveys. Alexey Bershov, the general director of the Petromodeling Group of Companies, a lecturer at the Department of Engineering and Environmental Geology of the Geological Faculty of Lomonosov Moscow State University, tells about what is currently happening in the field of engineering surveys and about how the information obtained at this stage of construction affects the further course of work. The original material was published in № 4 of the “Avtomobil’nyie dorogi” (“Motor roads”) journal in 2024.

Keywords: motor roads; engineering surveys; design; construction; safety; reliability; cost; time constraints.

Abstract: Meetings can be successful and unsuccessful, necessary (as it seems to the managers) and unnecessary (as subordinates sometimes think). Meetings can contribute to the search for effective solutions and, on the contrary, they can stultify the participants, take away their strength. The editorial staff of the “Geoinfo” journal asked some experts about how the communication systems are built in their companies, how often meetings are held there, what problems there are, as well as how to communicate in order to get the desired results, and how to act in difficult situations.

Keywords: meetings; frequency; duration; goals; results; moderator; business communication ethics; trainings; individual approach.

Abstract: Elena Chegotova, advisor to the chairman of the St. Petersburg Construction Committee, often speaks at industry events and talks about the digital reform. In her opinion, every building company has its own digital technologies. The gaps between the regions, between Moscow and almost all the regions are very large. As for St. Petersburg, it also has its own digital technologies. In some ways, this city is even a digital leader. You can learn a lot of information from Elena Chegotova’s speeches, but many questions still arise. So, the editorial staff of the “Geoinfo” journal invited her for an interview.

Keywords: construction industry; digital reform; digitalization; crisis situation; really working tool; transparency of business processes.

Abstract: The Ministry of Finance of the Russian Federation has developed a draft law on tax amnesty for business fragmentation. All the violations for 2022–2024 will be forgiven in exchange for good behavior in 2025–2026. This document is still being improved in the State Duma. At that, business representatives think that it will still remain evaluative, because the Federal Taxation Service considers that the possession of more than one company by one owner may indicate tax evasion. Therefore, when creating several enterprises, the owner must be ready to defend his or her position in the Federal Taxation Service. The editorial staff of the “Geoinfo” journal asked some entrepreneurs about why they divided or did not divide their businesses, and asked a tax consultant how to work correctly in such cases.

Keywords: business fragmentation; business fragmentation criteria; tax burden; tax evasion; tax amnesty; business consolidation.

Abstract: The state is trying to increase the tax consciousness of entrepreneurs in every way: it reminds them of payment deadlines and responsibility for hiding incomes, it gives tax amnesty for business fragmentation. At that, one of the goals of digitalization of construction is to make all the financial processes transparent. The editorial staff of the “Geoinfo” journal invited some experts to talk about how to save on taxes without exceeding the limits of what is allowed, and how to respond to claims from employees of the Federal Taxation Service.

Keywords: construction company; taxes; tax evasion; tax reduction; tax minimization; legal scheme; illegal scheme.

Abstract: The publication is devoted to a comprehensive project for engineering protection of the Tuluchi-Akur section on the Baikal-Amur Mainline in the Vanino District of the Khabarovsk Territory. This 2 km long section, which is located in a mountainous area, is characterized by high risks of rockfalls and snow avalanches. The paper considers the implementation of its engineering protection in 2023–2024 according to the project carried out by the SpetsProektPut company with the participation of PC TRUMER LLC, with construction and installation work carried out by the TransGeoService company. The article describes the conducted surveys of the area, including geological and geodetic studies. It also describes details of the implementation of design solutions for the installation of anti-rockfall and anti-avalanche barriers. The article emphasizes the importance of accuracy of engineering surveys and professional approaches to the implementation of engineering protection projects on hazardous sections of railway tracks.

Keywords: hazardous slope processes; engineering protection; engineering surveys; slope terracing; anti-rockfall barriers; anti-avalanche barriers; railway tracks; Baikal-Amur Mainline; Tuluchi-Akur section.

Abstract: Perhaps, there are not more controversial, debatable and endlessly debated types of research than geophysical ones. And the work performed with the help of ground penetrating radars (GPR) stands apart among them. Someone conducts them everywhere, and someone considers them pure “shamanism”. We have made one more attempt to understand the corresponding issues with the help of specialists. Nurbulat Amangel’diyevich Duysinaliyev, the general director of “Interrascan” LLC, and his deputy Georgiy Vasil’yevich Bychkov told the editorial staff of the “Geolnfo” journal how to orientate oneself in the Russian market of GPRs, what opportunities these devices provide, how they facilitate the work of engineering surveyors and when they can or cannot be relied upon.

Keywords: engineering surveys; geophysical technologies; georadiolocation; ground penetrating radars (GPR); deep GPR; radio pulses; reflecting media interfaces; radargram; drilling.

Abstract: Participants of professional chats are discussing the new draft law on the transition to single-stage design during the construction and reconstruction of linear facilities. The corresponding law will come into force in the autumn. The authors of the document are confident that then pipelines, power lines, railways and motor roads will be built and reconstructed faster and cheaper. The engineers who will implement this idea view it as “one more experiment” and are debating whether it will be successful or unsuccessful. The editorial staff of the “Geoinfo” journal prepared an overview of the discussions from professional chats and additionally asked some experts about the new draft law.

Keywords: draft law; single-stage design; construction cost reduction; construction acceleration; engineering surveys; design; financing; expenses; cost; timeframes; risks; safety; quality.
