The International Public Organization for the Promotion of Construction Education (ASV) has summed up the results of the competition of final qualification works. SPbGASU students and graduates became its laureates.

Anastasia Babinova won first place in the nomination "Bachelor's project in the field of construction technology and organization" with her work "Design and construction of a complex of buildings and structures of a technopark in the city of Vladikavkaz". Anastasia continues her studies in the Master's program. Her supervisor Sergey Bovteyev, Associate Professor at the Department of Construction Management, tells about the student's work:

– Anastasia Babinova's final qualification work examines a complex of facilities, the architectural solutions for which were fully developed by the graduate herself during her third year of study. She was much assisted by Margarita Aleksandrovna Gurieva, senior lecturer at the Department of Architectural and Engineering Constructions. In addition, the project adopted a number of non-standard organizational and technological solutions, and also used modern calendar-network planning software. Of much help were the knowledge gained from studying the course "Organization of construction", taught by Roman Vladimirovich Motylev, Head of the Department of Construction Management, and Vera Mikhailovna Chelnokova, Associate Professor at the Department of Construction Management.

Tatiana Pletnikova was awarded a diploma for effective participation in the competition in the nomination "Construction technology and management". The topic of her research is "Application of 4D modeling in the organization of construction of a 27-story monolithic residential building". Tatiana Pletnikova's work was also supervised by Sergey Bovteev.

Anna Rerikh's project "High-tech building solutions using nanocellulose" became the second among the research works of masters in the direction of "Production and application of building materials, products and structures". Her supervisor was Georgy Khrenov, Associate Professor at the Department of Technology of Construction Materials and Metrology.

– Anna Vladimirovna demonstrated incredible diligence and perseverance. This allowed her to complete the work at a high level in a short time, publish several articles, including in a journal from the list of the Higher Attestation Commission. But most importantly, she managed to obtain interesting scientific results, determining the rational area of ​​application of nanocellulose in building solutions. Anna Vladimirovna summarized the obtained results and developed a draft of practical recommendations that can be implemented in production, - said Georgy Khrenov.

Timur Aibedulov with his work "Ventilation of the SPbGASU educational building at Serpukhovskaya St., Bldg. 10 (TIM-project)" won second place in the nomination "Heat and gas supply and ventilation (project)". The work was supervised by Kirill Sukhanov, Associate Professor at the Department of Heat and Gas Supply and Ventilation.

As Kirill Sukhanov explained, Timur carried out the work as part of a comprehensive TIM project. The team consisted of several participants: an architect, a designer, a coordinator, an estimator and specialists in engineering sections. As part of the project, a 3D scan of the building was performed, and a full inspection of the facility was conducted.

– Timur conducted a survey of the existing ventilation systems of the building. Based on the data obtained, he created an information model and performed verification calculations of the ventilation system. After creating an information model of the existing facility, a model of the building reconstruction was created. Timur performed the necessary calculations, selected ventilation equipment. Particular attention was paid to the design of the ventilation systems of the atrium and parking. A ventilation system for the assembly hall was also developed while preserving the historical ventilation grille. Research was carried out on the parameters of the microclimate of the assembly hall with various ventilation equipment. The research was carried out using numerical modeling methods. The results obtained allowed to select the optimal equipment that provides acceptable microclimate parameters, - said Kirill Sukhanov.

Kristina Astashkevich with her work "Design of foundations of a multi-storey building with a single-level underground parking in the Kalininsky district of St Petersburg" took third place in the nomination "Bachelor's project in the field of geotechnics". Now Kristina continues her studies in the master's program. Her supervisor is Andrey Boyarintsev, Senior Lecturer at the Department of Geotechnics.

– No construction project can be completed without geotechnical calculations, because each building requires a foundation. Moreover, in dense urban development, there is a need for additional parking spaces. According to current urban planning concepts, underground parking is the best solution for apartment complexes, as it saves above-ground space that can be occupied by public areas or green spaces. However, in the conditions of St Petersburg, underground construction is complicated by weak water-saturated soils, which requires complex engineering solutions for the construction of the facility. It was this case of underground parking construction in a multi-story residential building, erected on weak soils, that was considered in the final qualification work. Now I continue to do geotechnical calculations, including in poor engineering and geological conditions. I am also involved in projects to strengthen the foundations of historical buildings in St Petersburg, - said Kristina. The student is grateful for the help, consultations and important engineering solutions from Andrey Boyarintsev and Anatoly Osokin, Director of the SPbGASU Soil Testing Center, Head of the Department of Geotechnics.

Linda Fortas came in third in the nomination "Master's research in the profile "Heat and Gas Supply and Ventilation"" with the work "Air-thermal curtains for large-sized gates". Her supervisor is Viktor Puhkal, Associate Professor at the Department of Heat and Gas Supply and Ventilation.

– At automobile transport enterprises intended for repair of heavy-duty vehicles, large-sized gates are used for entry and exit. Recommendations and methods for selecting air-thermal curtains for such gates are absent. That is why Linda chose the topic of her master's thesis "Air-thermal curtains for large-sized gates". The work includes studies of temperature and speed fields for various designs, positions and sizes of curtains. The influence of coolant parameters on the efficiency of curtains is also studied. The strengths of the work are the novelty of the research and consideration of issues of energy efficiency of air-thermal curtains, - said Viktor Puhkal.

In the nomination "Master's Research in Geotechnics", Daria Paskacheva distinguished herself with her work "Stress-strain state of flexible enclosing structures in conditions of weak clay soils", taking third place. She was supervised by Ivan Dyakonov, Associate Professor at the Department of Geotechnics.

According to Daria, the high level of development of geotechnics in St Petersburg is associated with the prevalence of “weak” clay soils in the city, which requires a highly scientific calculation approach to ensure safety during construction.

The SPbGASU Department of Geotechnics occupies a leading position in the field of calculations and design in such conditions.

– I chose this topic because I became interested in what needs to be done to ensure the accuracy of geotechnical calculations in St Petersburg's natural conditions. Geotechnical calculations themselves, it seems to me, always include a large share of creative scientific work due to the complexity and relative youth of such a discipline as soil mechanics, - noted Daria Paskacheva.

Currently, Daria continues to develop this topic in graduate school. The main component of her dissertation is the development of her own mathematical model of weak clay soil. In addition, in a team of graduate students and young teachers of the department, she is working on the creation of a software package based on the finite element method, which will allow the implementation of this model.

– I would like to express my deep gratitude to my supervisor in the Master's program, Associate Professor at the Department of Geotechnics Ivan Pavlovich Dyakonov for his support and guidance, which played an important role in my admission to graduate school and continuation of research in this area. I would also like to thank PhD student of the Department of Geotechnics Ivan Borisovich Bashmakov for his inspiration and assistance in choosing geotechnics as the main direction of my scientific and design activities.
