Stadium on Krestovsky Island. Difficult decisions of builders

The final stage of the construction of the football stadium on Krestovsky Island involves the use of complex engineering solutions. Vitaly LAZUTKIN, Director General of the General Contractor, Inzhtransstroy-SPb LLC, talks about non-standard approaches to managing this unique project.

Vitaly Vitalievich, this is probably the most unusual project in your practice. How is it different in the first place?
- The peculiarity of the object is not only in its uniqueness, but also in the fact that the work has to be carried out in cramped conditions. On a site of eight hectares, where a sports and concert complex is being built, general construction work is underway, the most complex structures and engineering facilities are being installed. Only in terms of construction and installation works, the project is comparable to the construction of several residential microdistricts.

The category of technically complex can, for example, include the device of load-bearing reinforced concrete structures of non-standard shape. By the way, a special composition of self-compacting concrete was also developed for them. During the construction period, more than 40,000 tons of metal structures were installed at the stadium, some of which have a complex configuration and are unique technical structures in themselves.

– Did you have to make difficult decisions from an organizational point of view?
– Of course, because the construction, design and reconstruction of the facility are going on at the same time. In addition, examinations are carried out in parallel. Now the fifth one is being prepared. The fact is that it was originally planned to build a club stadium. And in 2012, it was decided to host the semi-finals of the 2018 FIFA World Cup here, and the project was revised. The arena's capacity has been increased to 68,000 seats.

As a result of these and other changes, a large amount of restructuring work had to be done. So, in order to increase the capacity of the facility without changing the base and building area, it was necessary to change the dimensions of the places for the passage and evacuation of spectators. Only 7,000 cubic meters of concrete were dismantled.

What exactly needs to be rebuilt?
– First of all, an analysis of the bearing capacity of the piles was carried out. It turned out that during the two years of restructuring, the pile foundation was not loaded according to the design solution and the soils stabilized. However, it was decided that this was not enough. To secure the future building, the thickness of the grillage slab resting on the pile field was increased by 1.5 m along the entire perimeter. As a result, the level of the floor in the lower rooms rose by the same amount, which made it necessary to build additional stairs and ramps.

In addition (between marks 6 and 14) an additional technical floor was introduced. Also up to 40,000 sq. m, the area of ​​commercial premises planned for shops, cafes, restaurants was increased.

- What parameters of the stadium had to be brought into line with FIFA requirements?
- Every year this organization publishes a rendering of the requirements for the host side of the World Cup. The parameters of office premises for accommodating stewards, security, television and radio commentators are changing, as well as the ranking of VIP zones. This, of course, must be taken into account during construction.

In addition, according to the key requirements of FIFA, the angle of the stands was changed by a couple of degrees. Therefore, we had to dismantle and level the previously constructed reinforced concrete structures. In addition, during the initial design, the routes and scope of work for laying communications were not determined. Therefore, subsequently, in the finished walls, the thickness of which in some places reached 1.2 m, it was necessary to punch channels for laying networks.

– Tell us about the unusual technologies and materials that were used in the construction.
- Many of the solutions, some of which were laid down in the initial draft of Kise Kurokawa, and the rest appeared during subsequent editing, are unique. In particular, very complex engineering solutions were applied at the facility. The most difficult from a technical point of view was the installation of a stationary roof. In the course of the work, it was necessary to refine design solutions, recalculate the loads of many load-bearing structures, and reinforce some sections of the roof. In particular, it was decided to increase the rigidity of the translucent elements. That is, we built and designed at the same time, making improvements along the way. And this happened in all areas of work.

Even after the examination of the stage "P" project, improvements were required. Optimization of the project in some places made it possible to reduce the cost and simplify solutions, and in critical places where serious constructs and load-bearing elements were used, on the contrary, we followed the path of increasing the bearing capacity and improving safety. This primarily concerned load-bearing concrete structures, roofs, support posts and pylons. For example, pylons are designed by the architect in the opposite direction from the application of the load, towards the tension of the guys, and therefore are not self-supporting.

From the point of view of process mechanics, this position cannot be called optimal. We needed additional shrouds to hold the pylons, and when installing them, additional supporting structures were used that crossed the entire body of the stadium, right down to the base. This, in turn, did not allow us to fully engage in the laying of engineering networks and the closure of the thermal circuit in the premises where these supporting structures passed. For the sake of the architectural concept of Kurokawa, we had to complicate the work. In principle, this applies not only to inclined pylons, but also to all the original ideas of the concept - to a sliding roof, a roll-out field. All of these solutions have been retained, but the cost and complexity of their implementation is above average.

- Wasn't it obvious at the project examination stage? Why was the architect not offered to replace expensive solutions with optimal ones?
- Complaints have been made. Taking into account the comments, the project was recalculated twice. However, when Kurokawa's project with its concept was approved by the winner of the competition, no one thought about the details. For example, how this architectural solution will work in a northern climate. So, the roof just hung on a system of pylons. At the same time, the architect clearly did not take into account the wind and especially snow loads that occur in our climatic zone.

In 2011-2012, Mostootryad No. 19 began the installation of the roof. When our designers undertook to calculate the parameters of the roof, it turned out that it was not capable of carrying standard loads. The work was stopped, the roof was partially dismantled and counted. Some of the metal structures were deemed unusable, and new structures were ordered. In 2012–2013, the roof support system was also recalculated. In 2014, a new roof project appeared. We redistributed the load. Now the pylons in many ways perform a decorative rather than a supporting function. And the roof structure has become safer, because it rests on the stadium bowl through a system of small pillars. The pylons are designed in such a way that if one of them loses its bearing capacity, the roof will remain in a safe position.

– Did everything go smoothly during the installation of the roof?
- The work was divided into several stages. Installation was carried out by specialists from the Swiss company VSL. In the process, we had to overcome technological difficulties associated with stretching the cables, the system of which is unfastened through the pylons and supports the roof.

We did not have a single model of how the roof would behave, so we monitored the reaction of the metal in real time after the cables were tensioned. For this, a complex step-by-step tensioning system was developed. The strands of the guys were brought into the jacks through a special device. Each strand was stretched strictly for a certain load. In a circle, the cycles of application of tension loads were calculated, and the roof gradually redistributed its weight to the system of cables and pylons. We had to suspend work, in particular, due to jamming of the cables in the locks. In addition, when critical indicators were reached, construction was stopped at the request of scientists and field supervision specialists. With the help of complex mathematical calculations, the load models were recalculated. Therefore, the stretching process lasted a month and a half longer than envisaged by the project.

– A construction site is a living organism, and problems in interaction with contractors are inevitable. How did you solve them?
- Indeed, the interaction of the contractor with subcontractors is important, and sometimes it is necessary to go for non-standard solutions in order not to disrupt the contract. For example, the main roofing contractor was Mostootryad No. 19. In March last year, the company declared itself bankrupt and was unable to continue operating. There was a threat of a stop to construction, as subcontractors and suppliers associated with contracts with this company did not want to take risks and intended to curtail their activities. It took two days to make a decision.

We, as general contractors, promised that we would fulfill all obligations for current work on our own. About 500 people, employees of Bridge Crew No. 19, working at the facility, were brought into our staff. In a month, section No. 2 was deployed, where 12 subcontracting firms also joined. I had to make calculations, examine the amount of work in progress, transfer the library of as-built documentation to Inzhtransstroy, and perform procedures related to the bodies of Rostekhnadzor.

Now, in fact, it turns out that Inzhtransstroy, being the general contractor, carries out the most complex and responsible work on its own. Such a scheme is a rarity. In addition, under the state contract, our company is also a designer and developer of working documentation.

- Surely our readers will be interested in how the retractable field is technically arranged and why such a solution was needed?
– In our climate (and our stadium is the northernmost stadium of its class), football turf, the quality of which is now subject to high demands, is very difficult to maintain. In addition, the arena has high sides of the bowl, a stationary roof, which makes the insolation and illumination of the field minimal. To care for the lawn, the field must be extended.

The retractable field system is a structure weighing 7,000 tons, which is comparable to the mass of a large freight train. But at the same time, it must move quickly, smoothly and safely. The main task was to minimize the cost of moving such a massive structure. Several engineering solutions have been consistently proposed. At first it was about walking hydraulic jacks. An attempt was also made to complete the task at the expense of the winch system. There was even a proposal to make a floating field.

In the course of work, the concept was changed. It was decided to change the system of jacks to a system of electric servo drives. Then an air cushion was added to them. We seal the edges of the field, carry out blowing, which unloads the mass of the field through a system of air blowing fans. As a result, the load of 500 kg is reduced to 100 kg per sq. m. It takes about an hour to move the field. Thus, it is possible to care for the lawn, the half-meter-high pie of which consists of soil stabilized with special fibers. For the same purpose, the field is equipped with automatic heating, aeration, irrigation and drainage systems.

There is another reason for the introduction of a complex retractable system - the dual purpose of the object. It is known that the stadium will operate not only as a football arena, but also as a sports and concert complex. And no other events can be held on the football pitch

The innovative retractable field of the Zenit Arena stadium under construction on Krestovsky Island in St. Petersburg is unsuitable for playing professional football for tournaments under the auspices of international organizations. This became known during the visit of the FIFA delegation, which visited the stadium on October 31, 2016, with a scheduled inspection.

According to FIFA representatives, the roll-out field does not meet the regulatory requirements in terms of vibration, which are exceeded at the Zenit Arena by almost seven times.

“One of the guests decided to just run and jump around the field, and then suggested that other members of the delegation do it,” said a source familiar with the FIFA inspection process. “Of course, you can run and jump there, it just feels a little like running on the roof of a large house, with a metal roof covered with a carpet,” workers who were present at the first lawn tests, which took place at the end of October 2016, share their impressions.

As the builders themselves explain, the whole point is that even after the retractable field is rolled up, its steel base remains on wheels, leaving a void between itself and the concrete floor of the stadium. In addition, either due to design errors or cost savings, the retractable steel structures were found to be light enough to cause the side effect of springback.

Why the Zenit Arena field vibrates and springs

Successful experience in the construction of retractable turf stadiums already exists in Germany, the USA and Japan. But in all cases, a reinforced concrete moving box was used there with a total weight of structures of at least 10 thousand tons. In the case of the Zenit Arena, the builders decided to make the base of the field from steel, and during the construction process they also lightened the structures from the planned 8.4 thousand tons to 6 thousand tons of metal.

Obviously, now the authorities of St. Petersburg will have to decide whether to make a new retractable field or lay out a stationary lawn at the stadium. Given the fact that there is no time or money for the first option, the answer is already obvious.

Recall that now the holding of the traditional Confederations Cup with the participation of the 7 strongest teams in the world - the champions of their continents - is now in doubt. The first match of the Confederations Cup is scheduled at the Zenit Arena on June 17, 2017, and the final match of the tournament on July 2, 2017 is also to be held here.

Previously, the authorities of St. Petersburg called the retractable field of the Zenit Arena the main "highlight" and an innovative solution that will allow the stadium to be effectively used not only for football, but also for mass concerts, exhibition events and folk festivals.

Complex roll-out structures of the field were called one of the reasons that led to a significant increase in the cost of building the Zenit Arena. The well-known Russian actor and avid football fan Mikhail Boyarsky in one of his interviews called the construction of the stadium "the construction of a monument to corruption."

As previously reported in the media,. And in terms of construction, the construction of the stadium in St. Petersburg, which began in 2007, has already exceeded the construction time of the famous Roman Coliseum, created 8 years in the 1st century BC.

As an agronomist from one of the Moscow football stadiums explained to RBC, “Even the best field can be ruined in three days.” According to him, there can be many reasons, for example, improper agrotechnical measures. “Weather conditions also play a big role,” he adds. “The field is a living organism.” In order to give an accurate assessment of what is happening on Krestovsky, the interlocutor of RBC says, it is necessary to take soil samples, check how the lawn was cared for: “Maybe people just went out onto the field and brought the infection with their boots.”

However, the chief agronomist of Zenit, Konstantin Kreminsky, is sure that the matter is not in the weather, but in the contractor who was hired by the previous general contractor, Inzhtransstroy SPb (in August 2016, he was replaced by the Metrostroy company). Kreminsky also mentions the name of that contractor - this is the Bamard company. “For nine months ... aeration has not been carried out even once. In addition, the contractor hired by the city did not prepare the field well for winter - no treatment with plant protection products was done. And when the retractable field was pushed inside the bowl at the end of February and the snow melted, the lawn was ruined. “We saw various fungal diseases, a lot of mold,” sums up the Zenit agronomist.

Small "trough"

Bamard received a contract to create a field for Krestovsky in the spring of 2016, having won a tender announced by Inzhtransstroy SPb. According to a representative of one of the companies participating in the tender, all relevant market players wanted to work in the largest arena of St. Petersburg - Russian Intersportstroy, Sport and Co, Procyon, Bamard, British company SIS, Slovak Engo. “This is a very attractive and status contract,” says RBC’s interlocutor, estimating the cost of designing and installing such a turnkey lawn at €1.8-3 million.

All tender documentation, as well as the conditions proposed by the winner, are commercial secrets. Inzhtransstroy SPb and Bamard refused to answer questions about the cost of the contract.

A representative of the company participating in the tender claims that problems with the field were predictable. And the whole market knew about it, including the contracting company, he says.

“The organizer of the competition, the general contractor for the construction of the Inzhtransstroy SPb stadium, in the terms of reference outlined the parameters that initially made the implementation of the work difficult,” says RBC’s interlocutor in one of the companies. The main problem was the depth of the so-called trough, which houses the lawn with all the "internal engineering". "Pie" of a standard field (grass and at least three layers of sand and gravel with communications that provide drainage and heating. — RBC) has a depth of 45 cm, in the terms of reference for "St. Petersburg" it was 40 cm, - says the interlocutor of RBC. “It requires a non-standard, even unique solution.”

According to the source, the companies participating in the competition drew the customer's attention to this, but the parameters of the terms of reference remained unchanged. RBC’s source in Inzhtransstroy SPb assures that it was impossible to change the terms of reference: “The technical parameters, including the depth of the “trough”, were approved by the customer, St. Petersburg, within the framework of the entire project, and it was impossible to change anything. All dimensions and parameters of the field were specified in the project. Given that the field was planned as a complex retractable structure, it was impossible to change the design parameters, the same depth, so we worked within the framework of an agreed project.”

According to an interlocutor in Inzhtransstroy SPb, the Bamard company proposed a reasonable technical solution to this problem, which was accepted.

Connected Contractor

An RBC source familiar with the details of choosing a contractor for the Krestovsky lawn says that Bamard was "lobbied at the highest level." “The Ministry of Sports has a long history of cooperation with Bamard on a program to build artificial turf fields, and Mutko personally recommended that clubs and regional authorities building new stadiums use the services of this Russian company,” he says. It was not possible to obtain confirmation of this information from RBC. The Ministry of Sports has not yet responded to RBC's request.

Bamard is one of the largest Russian manufacturers of floor coverings for business centers, cinemas, and hotels. The company is indeed one of the five largest suppliers of sports surfaces, a representative of another large company with a similar specialization confirmed to RBC. As follows from the data of the SPARK database, Bamard actively participates in tenders for the conclusion of government contracts, mainly for the supply and installation of artificial fields. Since 2013, the company has won 79 tenders for government contracts worth RUB 1.9 billion. According to Bamarda's website, the company has delivered more than 70 full-sized artificial football fields to sports facilities in different regions of Russia.

However, the company dealt with natural lawns only in a few cases. “They are mainly engaged in artificial football fields, multifunctional sports grounds for basketball, volleyball, handball. Natural turf for football is not their main business,” says a representative of another player in this market. On the official website of Bamard, it is indicated that the company laid natural fields at three major projects - at the Lokomotiv stadium in Cherkizovo, at the Petrovsky stadium in St. Petersburg, at the Khimki Arena in the Moscow region.

Over the past three years, the company has also won tenders for the reconstruction of the Chaika and Lokomotiv stadiums in Voronezh (RUB 12 million), a site in Samara (reserve field of the Metallurg stadium, RUB 44.9 million), and the Trud in Tolyatti (76 million rubles), as well as for the creation of a lawn at the Central Stadium in Yekaterinburg. The stadium in the Urals, like the lawn in St. Petersburg, will host the games of the 2018 FIFA World Cup. The rest of the mentioned fields will be training for the teams participating in the World Cup. According to a Bamard representative, the company also laid natural lawns in Astrakhan (Volgar Stadium) and Krasnodar (Central Stadium). he says.

The field in Yekaterinburg began to be equipped on April 1, the first sowing of grass will take place on July 1. The official deadline for commissioning the entire stadium under the contract is December 31, 2017, and the first matches are scheduled for April-May 2018.

According to media reports, the company laid natural turf in Kazan at the Kazan Arena, but there were also problems with it. The finalists of the Cup of Russia in 2016 - "Zenith" and CSKA - were forbidden to conduct pre-match training on the field, so as not to completely "kill" the lawn. After the match in May 2016, it was decided to re-lay the lawn at the stadium - and this was entrusted to another company. In Bamarda, the “loss of Kazan” is associated with a change in leadership at the local football club Rubin. “The club's new CEO was already working with another turf company, and he ordered the field to be repaved at the Kazan Arena,” he says.

​Ownerless lawn

The general director of Bamard, Alexander Prytkov, told RBC that when the Krestovsky field was handed over, all the necessary engineering systems were in working condition, and the stadium employees have everything they need to maintain the field. “The question is not the technology of sowing this or that lawn; in many ways, the situation depends on the quality and correctness of the application of agrotechnical measures at these facilities,” he said.

This statement contradicts the statement of the Zenit agronomist, who, judging by his words, is sure that until the last moment, that is, until the end of February, Bamard should have been responsible for the quality of the lawn. Prytkov confirms that this was the case, but disagrees with the conclusion of the football club employee. “In June 2016 we sowed the football field, in September we handed it over to the contractor. But even after that, according to the contract, we served him - there is a magazine with a schedule of feeding, watering, - says Prytkov. “Wintering the lawn on the street is a normal practice, the grass can withstand frost even at minus 20 degrees.”

According to Prytkov, the lawn after wintering is in a satisfactory condition. Visible coating imperfections are a natural consequence of winter, and the words of the agronomist of Zenit are explained by the general director of Bamarda with the desire of the football club to "play it safe". “Given that the Confederations Cup games will be held at the stadium, Zenit does not want to take responsibility for the state of the lawn, this is a political issue,” Prytkov told RBC. According to him, the company has the results of independent examinations, which indicate that there is no fungus and mold after wintering the lawn in the soil of the new stadium.

Troubled Stadium

The construction of the new Zenith stadium on Krestovsky Island began in 2007. The building was ordered by the mayor's office of St. Petersburg. Initially, the construction cost was estimated at 14 billion rubles, and the stadium itself was promised to be put into operation in 2009.

However, subsequently the project and its budget were repeatedly adjusted. As a result, Krestovsky has become one of the most expensive stadiums in the world and the most expensive in the history of Russia. By the time of delivery, its cost amounted to about 44 billion rubles.

This amount will definitely increase, recognize in the "Zenith", which took over the management of the stadium. The amount of additional costs depends on the scale of the problems, including with the lawn.

Zenit CEO Maxim Mitrofanov, in an interview with Fontanka, said that Zenit had already invested 1 billion rubles in the “finishing” of its new stadium, and in total, according to the football club, in the first two years of operation, the club budget will need to spend 5 .5 billion rubles to bring the stadium into perfect condition. “We are ready to bring it to mind and plan to eventually make it the home of Zenit, but we understand that objectively this will not happen conditionally before the 2019/20 season,” Mitrofanov said.

Replacing the lawn at Krestovsky, if it is really needed, can cost Zenit the full cost of its development and installation, that is, up to €3 million, according to a representative of one of the companies participating in the tender for the supply of lawn. However, he was unable to name the exact amount. “We don’t know exactly what needs to be fixed,” he says. “A football field is not only a lawn with grass, but also internal engineering communications, several complex drainage layers, their condition cannot be judged from photographs.”

A representative of another company participating in the tender for the supply of the Krestovsky lawn says that it is theoretically possible to lay the field, along with all internal communications, in an insufficiently deep "trough", but this carries potential risks. “You see, there are standard technological solutions for laying football pitches that are used all over the world and by which we can guarantee the high-quality functioning of all systems with proper care,” explains RBC’s interlocutor. - Surely, it is possible to squeeze the “pie” into an insufficiently deep container, but, firstly, fitting technologies to non-standard sizes will cost more, and secondly, no one knows how such a unique lawn will behave during operation: maybe everything will be in order, or maybe you will have to constantly change and repair something. ”

Alexander Prytkov assures that nothing will have to be changed and all internal communications of the lawn will work properly. “This is indeed a very complex engineering facility, the field has a very shallow foundation - there are no analogues in the world, but we are confident in our work,” he says.

Lawn laying specialists interviewed by RBC argue that it is impossible to “fit” the field to standard dimensions at an already built stadium, that is, to make the “trough” deeper, which means that the entire stadium will have to be rebuilt.

Field

The combination of a retractable roof and a roll-out field will be one of the main know-hows of the stadium. The field with dimensions of 120*80 m will move with the help of a system of electric motors, after being lifted up with the help of forced air. During football matches, the field will be located inside the stadium bowl, and for the period of concerts, exhibitions and competitions in other sports, it will be located outside the stadium.

This solution will help to maintain the high quality of the turf throughout the year and avoid the need to replace it repeatedly, which is inevitable for classic football arenas. To maintain a constant temperature and humidity level, the field will be equipped with an aeration and electric heating system. The time required to move the field and all related procedures will be about 6 hours.

Roof

The retractable roof will provide sunlight on days when the football field is inside the stadium: without the proper amount of sun, the lawn will not grow. In addition, according to FIFA regulations, matches must be played outdoors. The retractable segment will satisfy this requirement and provide comfortable conditions for visitors to the arena during the winter period, during which the roof will be closed. But most importantly, the new stadium will create comfortable conditions for visitors at any time, including in winter. In order to close the roof, for example, in case of bad weather, it will take only 15 minutes.

The retractable roof is a complementary technology to the field: it will allow sunlight to enter on days when the football field is inside the stadium.

IT infrastructure

Wireless access

The stadium on Krestovsky is a large-scale IT project that takes into account all the needs and helps to realize all the possibilities of a modern sports facility.

The area of ​​the stadium will be covered by a network of wireless Internet access (wi-fi): the capacity of the projected network is 436 access points. The network will provide unlimited access to the Internet and internal media resources for VIP, VVIP visitors and skybox guests. It will also be available to media representatives and stadium staff. In addition, the network will keep the arena in touch with the staff of the situation center.

Data processing and transmission

The technological capacity of the stadium will be provided by 250 km of fiber optic networks. All information generated at the stadium will be stored in a single data processing center (EDPC) with a capacity of more than 50 TB. Such a powerful infrastructure is able to support the work of any application software that exists today.

The stadium will deploy a data transmission system with 15,000 ports and two Internet connection channels. A separate line is provided to ensure the exchange of data of integrated security systems.

The speed of information transfer between the switches via duplicated optical channels will be 10Gbps. The data transfer rate for connecting user equipment is 1Gbps.

Checkpoint system

The payment and access system of the stadium is a single software and hardware complex for full-fledged automated work with visitors to the arena. It is intended for information and reference services, the provision of specialized paid and free services and the organization of access control for viewers.

The following operations will be carried out using the payment system:

  • sale of tickets, subscriptions and cards using all possible channels, including the Internet and ticket operators;
  • access control of viewers of various categories and registration of unauthorized access attempts;
  • monitoring of spectator access control devices;
  • conflict resolution by employees during automated input control;
  • accreditation of certain categories of visitors;
  • parking automation;
  • issuance, acceptance of parking tickets and collection of payments for parking;
  • billing automation;
  • automation of power points;
  • ensuring sales of goods and services of the stadium with a non-cash payment system;
  • real-time display of system processes, including the process of filling the stadium;
  • obtaining statistical and analytical information about visitors, their interests and their attendance;
  • formation of financial and reporting information and transfer to the accounting system.

In the future, the system can be used to implement a visitor loyalty system.

Stadium security

CCTV

A video surveillance system will be installed at the facility, which allows you to follow any of the spectators from the entrance security cordons to the place on the podium. The system identifies the ticket, appearance and track record of the fan. A total of more than 600 video cameras will be installed in the under-tribune space of the stadium. The main task of video surveillance is to record illegal actions and identify violators.

Security alarm

To protect against unauthorized entry into the stadium by unauthorized persons, the stadium will be equipped with a security alarm system. The project provides for about 3.5 thousand magnetic contact detectors installed on doors and windows, about 200 broken glass detectors and more than 1 thousand optoelectronic detectors that control the volume of premises.

Access control and management system

To organize the access of personnel and visitors to various areas and premises, as well as to protect against unauthorized access by unauthorized persons, an access control and management system will be installed at the stadium. Entrance and exit to the premises of the facility will be carried out using electronic cards, for which the installation of door controllers, electronic card readers and blocking elements is provided. Any door can be unlocked from automated workstations of security posts. More than 1,000 access points will be equipped with an access control and management system.

Fire alarm

The fire alarm system is designed to detect a fire in the initial stage and generate control signals to turn on various systems. In the event of a precedent, a set of measures is provided for at the stadium: notification and operation management (transition of the operation of the facility into emergency mode), starting the smoke exhaust system, turning off the ventilation systems, controlling elevators, turning off technological equipment, etc.

The system will be built on the basis of 16 fire stations located in different parts of the building and united in a local network, which is one decentralized station. More than 10,000 multi-sensor and 2,000 manual call points will be used as sensors.

Fire extinguishing system

Several types of fire protection systems will be installed at the facility. In control rooms - powder fire extinguishing, in switchboard rooms - gas fire extinguishing and water - in all other rooms. Sprinklers are provided in the under-tribune spaces of the arena, and internal and external translucent structures (stained-glass windows, windows, doors) will be irrigated with finely sprayed water in case the system is triggered.

One of the unique features of the facility will be a fire extinguishing system in the stands area - a robotic fire complex. When a signal is received, the fire robot determines the location of the source of fire and performs automatic fire extinguishing with sprayed water. The robot is equipped with "technical vision" consisting of an IR sensor with a scanner and a TV camera. He is also endowed with intelligence: determining the coordinates of the target and pointing at the source of ignition. Fire robots are connected by an information network controlled through a central console and integrated into an integrated security system.

Stadium management

Single control center

A single center is a communication and control center, from where the personnel responsible for the operations of the stadium will monitor the processes taking place in the arena and manage all engineering systems, responding to any situations that arise - both before the start of the event, as well as in its process and after the event.

Monitoring systems

The system monitors all subsystems: security systems, life support systems, fire protection, communication systems, informs the duty personnel of the Center for Monitoring and Forecasting Emergency Situations, the day-to-day management body of the Unified State System for Prevention and Elimination of Emergency Situations (RSChS) about the occurrence of pre-accident, emergency, emergency situations and fires.

Even in crisis situations, the stadium's communication and control system provides guaranteed stable telephone communication between the operational and rescue services, special units and the emergency response headquarters at the facility. The system for monitoring engineering (bearing) structures of the stadium is carried out in real time and allows you to track changes in the state of engineering (bearing) structures.

Stadium remote control system

The automatic stadium remote control system is designed for centralized monitoring, dispatching and control of a number of engineering systems:

  • energy saving
  • sports lighting
  • heating
  • ventilation
  • air conditioning
  • heat supply
  • boiler room
  • thermal curtains

The arena will be equipped with specialized lighting that meets all conditions for the comfort of players, spectators, referees and TV cameras. In particular, to eliminate the flickering effect during slow and super slow repetitions, electronic and high-frequency ballasts were used for spotlights.

The sports lighting project provides for emergency television lighting - the possibility of continuous television broadcasting and the normal conduct of the match in the event of a power outage.

The stadium will be provided with power supply for the lighting installation of the football field according to the first, special category, using an independent backup power source and an uninterruptible power supply. Due to this, 100% of lighting devices remain in working order, providing non-standardized levels of illumination for 3 hours. That is, even if the entire city turns out to be disconnected from electricity, visitors to the stadium can watch the game without noticing any changes.

The lighting equipment of the stadium will be located on a special circular technical bridge, providing unhindered and convenient access to it at any time. The bridge is located in the space between the trusses (“rails” along which the sliding part of the roof moves) and is connected by a system of transitional radial bridges with exits to the roof.

Visitors with limited mobility

At the entrance to the stadium, information stands will be installed with information for people with limited mobility, including indicating the direction of movement to the accessible entrance.

The stadium also provides:

  • special lobbies;
  • elevators;
  • ramps for delivery by auxiliary vehicles;
  • special control devices

To ensure accessibility for people with visual impairments, tactile warning signs are equipped before each flight of stairs. The steps of the stairs are equipped with a protective anti-slip corner profile of a contrasting color on each step along the width of the march.

Bathrooms for people with limited mobility will be equipped with a call system for full-time medical staff on duty. In places where people with disabilities stay, two-way communication with the dispatcher will be installed.

Energy efficient solutions

Comprehensive indicators characterizing the specific value of the consumption of energy resources make it possible to attribute the building to the energy efficiency class A ++ (very high).

All materials and technologies used for the construction of the stadium are environmentally friendly and meet the high standards of the LEED international certification system: cables that do not emit halogen during combustion (HF cable), energy-saving lamps, etc.

The equipment corresponds to the high technical level of the project and has the highest energy efficiency class due to the use of the most advanced technological developments. In particular, the stadium's OTIS elevators are equipped with a ReGen regenerative drive that redirects the generated energy, normally dissipated as heat in braking resistors, back into the building's electrical grid. Thus, clean "green" energy is produced, and energy savings can reach 40-75%.

Fontanka found out the details of plans to move the media campus near the stadium on Krestovsky and roll out the field. The feds will add half of the money for this, and Zenit, apparently, will have to play next spring with CSKA at Petrovsky.

The roll-out field of the stadium on Krestovsky will again become roll-out at the end of December, the city and the federal center have waited for a signal from FIFA. Now they will equally invest in the transfer of the media town, which prevents the lawn from earing in the sun. They will take the field as soon as necessary, there is not enough time. Only next year the lawn will be completely replaced on it again. An unobvious privilege to play on fresh grass should be given to SKA-Khabarovsk in May. According to Fontanka, Zenit will play with the Moscow army team the old fashioned way - at Petrovsky.

Judging by the haste, the decision was delayed after all. The field meeting led by Deputy Minister of Sports Pavel Novikov was held on October 18, according to Fontanka, Komstroy had to approve the project documentation by October 24. In turn, ANO "Arena-2018", which is responsible for meeting the deadlines for the construction of stadiums for the 2018 World Cup, by Wednesday, October 25, must include the dismantling and transfer of the media town to the estimate. The Ministry of Sports will hurry further: a day after the submission of all the necessary documents, it will prepare an order on the transfer from the federal budget to St. Petersburg: the center takes on half of all expenses.

Funding limits are still unknown, the construction committee must form them by November 3. This means that additional funds will be contributed to the draft budget for next year before the second reading, which will take place on the 22nd. Now, 220.3 million rubles have been set aside for various events related to the stadium in 2018. However, during the zero readings of the budget, Komstroy named about 400 million more as additional needs, including for the transfer of the media campus. Then, in the form of a completed application, these figures did not reach the Finance Committee, now they will not go anywhere. Previously, disassembly and transfer were estimated at between 100 and 200 million euros.

Apparently, IC "Mir" will be engaged in the work. She built this media town, and since 2014 she has been decorating the stadium. The company is registered in Moscow, owned by Serbian citizen Slobodan Kovacevic. It was stadium contracts that became the main source of revenue for the company. Around the same years, IC Mir received contracts for the construction of the historical park "Russia - My History" and an indoor skating rink in Strelna for a total of more than 2 billion rubles. By December 19, the media town will be dismantled and moved in parts to the sixth parking lot, slightly shifted to the west, as well as the “TV broadcaster zone”, where mobile television stations come. It will be mounted in a new place by the end of January.

Earlier, Fontanka already wrote that on December 20, the roll-out field of the stadium should leave for the vacant seat. We are talking about a test run, until January 15 there will be time to troubleshoot possible problems. And they are very possible. Previously, the field was running only according to a temporary control scheme, now the regular one should be launched. This, in particular, means that the system can work with the failure of a certain number of drives. But the concrete slab in front of the stadium has not yet been leveled, along which a structure weighing 5,000 tons on 400 wheels should ride. This means that a “full cycle” is excluded, during which the air cushion is turned on and thus the load on the supports is reduced by a factor of three. That is, 36 injection modules will be launched, they will create an impressive roar with their six thousand revolutions per minute, but air will leak out from under the rubber skirt located along the perimeter of the field. The source of the publication, close to the construction, said that for the same reason, additional shelter of the viewing hole is required. It is located in the direction of the field, and if the level difference remains in the closed position, you can forget about tightness.

It is significant that the day of the test rolling can be changed due to weather conditions. The main problem is icing. Tractors simply can not go on slippery ground. And if they go on water, then when the temperature drops, the structure can freeze, this has already happened, they were heated with gas. After rolling out, the field is pushed back.

Nevertheless, the dismantling of the media campus is a settled issue. And not Smolny, who, as in a joke, may or may not dig. “The options that we have included in our multifunctional cultural and sports complex should work,” says Vice Governor Igor Albin. - In addition, the decision was made by FIFA experts. We were ready for any option. If the field acquired a roll-out function after the World Cup, that would suit us too.” The future of temporary structures is unclear. The rush and winter conditions in which the transfer is taking place make it doubtful that the media town will remain at the sixth parking lot for good.

In addition, no one canceled the whims of the "big brother" from among international sports organizations. “We were faced with four different standards for the use of the stadium and everything adjacent to it,” says Albin. - One included in the project; two different FIFA standards - for the Confederations Cup and for the World Cup; and one Zenit. But soon we are waiting for the fifth. In 2020, the European Championship will be held in 13 cities at once, including St. Petersburg. I think that until then the stadium will be operated according to Zenit standards, and we will prepare the arena together for the European Cup standard. So it is possible that the conditional "IC" Mir "in three years will have to move the media town a little more.

A little clearer prospects for the coming spring. Zenit will be forced to return to Petrovsky for at least one match, already inhabited by the Tosno football club. According to Fontanka, from April 16 they should start changing the lawn at the stadium on Krestovsky Island for the World Cup. On May 13, a test match will be held, after which the field will be rolled out of the stadium into the sun and returned back on June 11 for the World Cup. If you look at the schedule of the Russian championship, you can see that right before the "shaving" of the old lawn, Zenit will play two home games - with Krasnodar and Anji. After that, in St. Petersburg, the club has two matches left in the season. April 29 with CSKA, and this game, apparently, will have to be transferred to Petrovsky (Tosno is playing away with Rostov that day). The game with SKA-Khabarovsk is scheduled for May 13 - apparently, this is the same test match. It is not yet known how Zenit feel about the fact that perhaps the decisive match of the championship will have to be played at the old stadium, but the blue-white-blue were preparing for a possible move - it was not for nothing that season tickets were sold at once to two arenas. It is not known, by the way, how the lawn will survive the winter - and already in February, if everything goes well, continue to play in the Europa League.

As Fontanka previously reported, the 2018 Organizing Committee initially assumed that the temporary structures at the Krestovsky stadium would be dismantled after the Confederations Cup in order to be reassembled by the 2018 World Cup. Then information appeared that they could be left until the World Cup. Meanwhile, this meant that the stadium would not be able to take advantage of one of the main technical advantages - a roll-out field. This had a detrimental effect on the condition of the lawn. On April 22, Zenit played their first match at the new stadium, and the unsatisfactory quality of the lawn was evident. As a result, the club played 2 test matches at the arena instead of 3, and for the Confederations Cup the lawn was simply shaved off with a roll. Now the condition of the field is deteriorating again, during the break for national teams, some sections were replaced on it, but they did not begin to lay the whole new “roll”.
