St Petersburg Stadium, Krestovsky Island, Russia
St Petersburg stadium is under construction and will replace Kirov Stadium on Krestovsky Island in St Petersburg, Russia.
The landmark venue has been designed by Kisho Kurokawa and will serve as a multi-purpose destination for various events.
The stadium has been selected to host the FIFA Confederations Cup 2017 and semi-final matches of FIFA 2018 after Russia won the bid to host the international event. It will also be the home to local soccer club FC Zenit St Petersburg.
Completion of the stadium is aimed for mid 2016 with inauguration expected to take place in the same year. The stadium was known by several popular names such as Zenit Arena, Gazprom Arena and Piter Arena before an official name was selected in October 2015.
Background of the stadium
The delayed stadium has been under construction since 2006 after the design architect was selected through an international design competition in 2005.
The lead contractor for the project, Avant, abandoned the project midway, which led to the search for a new contractor.
Certain issues emerged after Russia's winning bid to host the football world cup was announced. Issues relating to the design had to be revised to increase capacity from the earlier 62,000 to 68,000 and also to build a stadium compliant with the highest international regulations.
Complicated by controversies and corruption charges, the construction cost of the stadium inflated from the initial planned sum of RUB6.7bn ($84.9m). Costs increased to RUB34.9bn ($442.7m), making it one of the world's most expensive stadiums.
St Petersburg stadium design
The stadium is designed as a 56.6m-high, seven-storey building with a massive dome and the roof will be held by eight large masts.
A retractable roof and a sliding pitch were included in the design to make the stadium one of the most modern arenas.
The retractable roof will enable the venue to host events throughout the year as temperatures within the stadium will remain moderate. It will also be equipped with a hot air inflated membrane structure that will melt snow during winter.
The innovative design of the sliding pitch will allow the movement of a field with the dimensions of 120m x 80m through electric motors with the assistance of air pillows. This arrangement enables the venue to be used for concerts, exhibitions and other sports as the pitch can be temporarily moved outside the stadium.
Facilities at St Petersburg stadium
The multi-purpose venue will be built in an area of 287,600m² of which 26,000m² will be occupied for commercial operations. The stadium roof will have an area of 71,000m².
Parking will be available for 240 slots inside the stadium, while an additional 2,732 spaces will be available on land adjacent to the stadium.
The stadium will have a capacity for 68,134 spectators during football games and it will be able to accommodate 80,000 theatre and concert goers. Seating will be arranged in two tiers with the lower level having a capacity of 22,000 people and the upper tier equipped to seat 46,000 spectators.
A total of 14,270 seats will be reserved for fans, 560 seats for spectators with limited mobility, as well as 104 luxuriously designed sky boxes. Eight snack bars and eight restaurants will be provided.
The stadium will be easy to access for disabled visitors with special lobbies, elevators and ramps for delivery by service vehicles, as well as warning indicators before each flight of stairs and special control devices.
St Petersburg stadium structure
The structure of the stadium weighs 32,000t, which is equivalent to the weight of four Eiffel towers. The amount of concrete used for constructing the stadium is five and a half times more than that used for erecting the Wembley Stadium.
The steel roof of the stadium is designed as a supporting truss structure that is round in the middle and resembles a concave-convex lens in profile with the playing field at its centre.
Carriageway trusses have been designed above the field to allow the roof to open and close. The roof is supported by eight inclined reinforced concrete pylons and a stay cable system that supports the dome.
The stadium's bowl will feature an exterior of silver-gray that will be achieved from aluminium composite panels, Alubond. Glazing products from AGC will be used to give finishing touches to the stadium's exterior.
The base of the facade will be composed of ceramic metal panel and an anti-graffiti and anti-vandal cover. A translucent ethylene tetrafluoroethylene (ETFE) film will be used for the retractable section of the dome to provide protection from the weather and can be used for projection purposes.
Key players involved
Transstroy was selected as the general contractor for the project in 2008 to replace Avant. Werner Sobek was selected to provide structural engineering and facade planning.
