Reopening the Grande Arche de La Défense in Paris

A new tourist attraction has arrived in Paris this season. After two and a half years of renovation, eight years after the closure, the roof of the Grand Arc (Grand Arc de la Fraternite) was opened to the public in the Paris area of ​​La Défense. The reconstruction and modernization was carried out by the Eiffage Group companies: Eiffage Construction and Eiffage Énergie, supported by the architectural studio Valode & Pistre.

The Great Bow of the Brotherhood, also called Grande Arche la Défense, was commissioned by French President François Mitterrand. The international competition for the Arc project was won in 1982 by a Danish architect, Johann Otto von Spreckelsen. The building was solemnly unveiled on July 14, 1989, on the 200th anniversary of the French Revolution, when the G7 summit took place in Paris. It was opened to a wide audience on August 26, 1989, on the bicentenary of the Declaration of Human and Civil Rights.

The project of reconstruction and modernization of the Great Arc was carried out in the PPP (Public-Private Partnership) formula. In September 2014, before the renovation works began, Eiffage signed a contract according to which he became the manager of the building for 20 years. Under the contract, Eiffage undertook, among others, for the maintenance of the building and ensuring the current maintenance of the roof availability until the end of the lease period (until 2034).

Planned works, in addition to renovation of the Grande Arche roof, also included the reconstruction and modernization of interiors, façade renovation and the assembly of panoramic elevators. The façade required a complete replacement: the beautiful Carrara marble was not very resistant to acid rain - it was replaced with a cladding made of much more durable granite. After the renovation, in March this year, offices located in the southern wing of the Great Arc were made available to the Ministry of Environment, Energy and the Sea (now: Ecological and Inclusive Transformation).
Currently, you can get to the roof of the Great Arch using panoramic lifts. A promenade bridge 110 meters long and 10 meters wide awaits at the top, from which there is an amazing view of Paris and its surroundings. There is also a restaurant on the terrace, which can host up to 50 people.

Grande Arche de la Fraternité is an almost perfect, hollow cube, 106.9 m wide, 110.9 m high, and 112 m deep. It weighs 30,000. tons and supported on twelve pillars, driven into the ground to a depth of 30 meters. Until 4 April 2010, when, due to the failure of one of the glass elevators, it was closed to the public, it was one of the most visited buildings in Paris.
For its construction, 2.5 hectares of anti-reflective glass and 3.5 ha of Carrara marble - the one used by Michelangelo for his works. The construction is gigantic: the Notre-Dame cathedral, with a spire, could fit under the Great Arch. Under Łuk is a nylon roof stretched on many ropes, called "Cloud", which stretches from 10 to 30 meters.

The companies Eiffage Construction and Eiffage Énergie belong to the Eiffage Group - one of the largest construction groups and concession operators in Europe. The Eiffage Group employs approximately 64,000 employees and generates annual turnover of around EUR 14 billion. All over the world, the Eiffage Group is known for its bold, ambitious and demanding projects. The Eiffage Polska Budownictwo representative is the Eiffage Polska representative in Poland.
