    Up to the blow of the wind

    Alexander Vorozhbitov

    On March 20, the next issue of the Sport-Business-Consulting magazine (No. 1 (40), March 2020) was published, in which two articles were dedicated to the Rhythmic Gymnastics Palace of Irina Viner-Usmanova. Alexander Vorozhbitov, General Director of Metropolis, in the article “With an Accuracy of the Wind” told about the design process, the peculiarities of project coordination, as well as the applied methods and software complexes.

    - Is it a special responsibility to design such a complex and original object?

    The creation of such a sports palace is the result of the well-coordinated work of many companies and specialists. More than 20 specialized design organizations took part in this project. The Metropolis company was engaged not only in designing, but also in coordinating the whole pool of participants. The author's idea of ​​the appearance of the building belongs to Sergey Kuznetsov, and together with Pride we have implemented architectural, planning and technical solutions. In particular, in the area of ​​responsibility of the Metropolis company were structural and engineering solutions. Personally, the project is especially interesting to me because we had to solve many non-standard tasks in a short time, develop complex technical solutions for changing tasks and implement systems that have no analogues.

    - How did you manage to create a roof in the form of a tape?

    On the monolithic frame, we installed arched beams supporting the roof from spatial trusses - metal honeycombs. This shape of the parts made it possible to create a roof-tape, ensuring the bearing capacity in all planes. We have performed tests and calculations for various situations, including exceptional ones in terms of load. Another advantage of this solution is the low weight of the structure. Such structures can be effectively used for coverings with large spans between supports.

    - How long did it take to work on the project?

    Two years. During peak periods, 40 Metropolis employees were involved in it. The examination for a building permit was passed at the first attempt. But the object itself passed the examination 3 times to agree on changes made to the project during construction.

    - What has changed in the project during construction?

    Various aspects: both constructive (replacement of wooden roof structures with metal ones) and engineering solutions, for example, power supply, technological blocks, logistics. New requests were received from the customer and the organizers of future events. We checked their requirements and made the appropriate changes. The project provided solutions that can be universal for all subsequent activities. But a number of activities require an individual, customized approval process.

    - Does a non-standard roof make it difficult to install equipment?

    We have provided technical rooms along the main gym. The height of the technical floor is up to 9 meters. For the first time, our specialists used frame three-level central air conditioners and ventilation units. The standard execution assumes two levels. This solution made it possible to place all the equipment required for the operation of the facility.

    - What else did you have to show your imagination in?

    We had a severe restriction of air movement in the center of the mat to have minimal impact on the gymnastic ribbons. To create the correct microclimate, the CFD mathematical modeling system was used. It is a modern tool for checking design engineering solutions for compliance with a functional task. With a large audience and the active use of electrical appliances, it turned out that warm air rose and formed internal convective currents. As a result, we increased the air exchange rate in the main hall by 50%, redistributed the supply and exhaust devices and set different supply air temperatures in different zones - they can be adjusted independently of each other. All this minimized the heat pressure in the central part of the arena. The solution for the organization of equipment suspensions to the supporting structures of the arena covering turned out to be very interesting, in total there are more than 180 possible fastening points for the implementation of any possible scenarios when carrying out events within a given total load from the equipment of 40 tons (and this is taking into account the maximum snow load). The solution itself was worked out jointly with the rental companies and their wishes were taken into account.

    I can also mention the possibility of modernizing the arena for eSports tournaments. From an engineering point of view, this is a special event, because you need to think not only about the mass gathering of people, but also about the increased requirements for electricity consumption and air conditioning. eSports requires increased power consumption and proper cooling of equipment. It is clear that special connections are made for a specific event, but the building infrastructure must support them.

    - Is the sound and light in the palace unusual too?

    Light can be considered a standard sports light, albeit of the highest quality, not interfering with athletes during competition and training. Special effects equipment is usually additionally installed by event organizers. Regarding sound, I can note the radio frequency sound reinforcement system in the audience seats for the hearing impaired. The equipment itself is professional, suitable for musical performances. There are 28 loudspeakers hanging over the arena, grouped into 16 clusters. It is also worth noting that the arena itself was prepared in terms of building acoustics, and the result turned out to be very decent for indoor sports and concert facilities, which ultimately simplified the work for rental companies when planning the placement of electroacoustic equipment.

    - Can the equipment be brought to the palace by trucks?

    This is implied by the logistics itself, the technology of the building's life, can't do without it. There is a loading area, back office, auxiliary technological rooms, warehouse and other premises.

    - How are the hotel and the medical unit organized?

    The hotel is located in a separate part of the building. This is a full-fledged five-storey hotel, intended primarily for athletes, although anyone can stay there. There are rooms for one, two, three and four people. Each floor has its own design; Irina Aleksandrovna was personally involved in the design. She also supervised the creation of a medical recovery unit, consulted with experts, and chose medical equipment - the best of the existing options.

    - Is there a smart facility management system?

    Yes, the project provides for a Building Management System. BMS is a computerized control system that controls the mechanical and electrical equipment of a building: ventilation, lighting, power supply, fire systems, etc. Various scenarios can be programmed. We always provide for such opportunities in our projects.

    - Did you have difficulties with the foundation due to the proximity of the Moskva River?

    The bearing capacity of the soil is initially not the best. Two solutions were considered - a continuous pile field with a common slab or pile grillages. Based on the results of the calculations, a solution with pile grillages was chosen. We try not to lay too expensive solutions in order to be able to complete the construction on time and stay within the budget.

    In the article "Modern Luxury" about the peculiarities of design solutions in the interior of the palace and the unique capabilities of exploitation, publication said Irina Viner-Usmanova, President of the Russian Rhythmic Gymnastics Federation, Sergey Kuznetsov, Chief Architect of Moscow, Mars Gazizulin, CEO of "Mosinzhproekt", Gennady Rutenburg, Head of construction, Nikolai Gordyushin, Head of the authors team of the creative production association "Pride", as well as Alexander Pankov, Director of the palace.
