The 140m-tall Trinity tower will be constructed for client Unibail-Rodamco along the eastern side of the CNIT building in the heart of La D茅fense. It will stand over the Avenue de la Division Leclerc expressway and the scheme will also require underpinning of the CNIT building and the installation of more than 1,000 micro-piles and piles.
The project, which will get under way early next year and is scheduled for completion in the second half of 2018, will be carried out by three Vinci Construction France subsidiaries, Bateg, GTM B芒timent and Sogea TPI. Vinci Energies will handle a number of technical work packages.
The Trinity tower is designed by Paris-based architecture firm Crochon Brullmann + Associ茅s and will provide 52,000m虏 of floor area over 32 storeys, including 3,000m虏 of new public and service areas.
It will be made up of two offset blades and will have balconies and gardens on every level on its eastern and western facades to channel a maximum amount of fresh air into the building. Rather than being 鈥榟idden鈥� inside, the lifts will be located on the outside of the Trinity building to allow for a better lighting. 聽The tower also aims for the highest environmental certifications: HQE Passeport B芒timent Durable Exceptional Level and BREEAM Excellent.
The main challenge will be build it within the densely populated environment. The high-rise will be built over the Avenue de la Division Leclerc expressway, which has seven traffic lanes that are to remain open throughout the construction work. La D茅fense services (buses, fire brigade, hotel supply, etc.) will also continue to operate normally.
With its fire-resistant concrete structure, the base on which the high-rise building will be built will accommodate an esplanade with an area of more than 3,000m虏 that will create new pedestrian connections.
鈥淭he Trinity tower will be built over the expressway, setting an example in creating additional land in the run-up to the Grand Paris programme, in which the city will rebuild above itself,鈥� said Hugues Fourmentraux, chief executive officer of Vinci Construction France. 鈥淭his ambitious urban high-rise building project is made possible by Vinci Construction France鈥檚 ability to pool its civil engineering and building expertise and capabilities.鈥�
Trinity is due to be completed in 33 months 鈥� 16 months for the esplanade and 17 months for the building.
