5 challenges of engineering in the London Olympics 2012
The Olympics are in the center for sport and the world’s eyes are upon the powers which representatives of each country give the best of themselves to reach the goal and overcome their records. However, besides these mega sports are home to major Engineering challenges, which involve installing a million visitors in a city, and give the best conditions for the athletes.
London 2012 are several developments that have been implemented, and maybe sometimes do not see why we are focused on the athletes. These are some of them.
London’s Olympic Stadium has a capacity of 80,000 people (third largest), but London does not really need a big stadium after the Games have finished. The solution reached by the engineers was that part of the Stadium is removable, allowing installation shrink when extra seats are not needed. The stadium has 25,000 seats then fixed and 55,000 who are on a lightweight steel and concrete. The roof is also removable.
The Basketball Arena, installed in the East London area, is even more radical than the Olympic Stadium: can be completely dismantled and removed, and indeed that is what will happen after the Games end. This is the largest temporary building constructed for one of these events.
The Arena is made of 1,000 tons of steel and wrapped in 20,000 square meters of white tarpaulin. At one point he thought that once it was removed the installation can packed and shipped to Brazil to be used in the next Olympics in 2016, however the costs of storage, transport and assembly would not feasible . The site has 12,000 seats and develop there basketball games and handball, rugby and basketball in addition to wheelchair during the Paralympics. It is unclear what will happen to the building when it is removed after completion of these games.
The Aquatic Center is one of the most striking buildings, on the wave-shaped roof 160 meters long and 80 meters wide. Due to its special design, the roof is supported on three concrete supports only. It is built entirely from recycled aluminum.
As in previous cases, after the games end this center will be transformed into a community pool, and a training ground for elite athletes. The two wings of the building will be removed, which will leave 2,500 seats available and could be increased to 3,500 for major competitions. With the wings installed, the building has a capacity for 17,500 spectators.
The center has a 50 meter pool for competitions, one for diving 25 meters and 50 meters for heating. The first is quite special: it has 3 meters deep, to be a pool “fast” – that is, it generates less waves, allowing swimmers to swim better – and the ground is mobile and can increase the depth of the pool if necessary up to 10 meters with ski stations of 5 meters and 7.5 meters.
The pool has three trampolines to 3 meters high, and the sides have some channels that carry excess water generated by the waves caused by swimmers. The idea is to dissipate the waves to affect as little as possible to swimmers, enabling them to achieve higher speed.
The London Velopark was challenging because it was installed in a place that had been a landfill for 100 years. The engineers had to install base to give stability to the building, which led them to dig 26 meters to bury 900 pillars that form the base. Unlike other buildings, the velodrome will be permanent and not removable. Also installed a BMX track on the outside.
The building is energy efficient: it allows the passage of sunlight to reduce the need for artificial light is artificial ventilation and collects rainwater for use in the installation.
The velodrome track is 250 meters and their installation were used 350,000 nails.
