Hekla tower in La Défense
26 December 2018 - New contracts - France
Hines and AG Real Estate have appointed Bateg (VINCI Construction France) to build the Hekla tower.
Designed by architect Jean Nouvel, this 220 m-tall skyscraper will boast six underground levels, a 48-storey superstructure, a 2-storey high entrance hall and a tree-planted roof terrace.
This new office tower, with a surface area of some 80,000 sq. metres, forms part of a project to develop the Rose de Cherbourg area in the heart of the La Défense business district, and will benefit from a landscaped park (1.3 hectares) and a planted walkway above the circular highway. Its façade, composed of 14 km of shading elements, will contribute to the thermal regulation of the building, reducing the amount of air conditioning required while ensuring a comfortable working environment for its some 5,800 future occupants.
Ivy Broomrape, a rare and protected flower, was spotted during earthworks. Bateg teams dug it up and transplanted it with help from a nursery garden. It will be replanted in the tower’s future "Sky Garden" on the 49th floor, in an effort to preserve local biodiversity.
A VINCI Energies joint venture formed by Phibor Opale, Cegelec Tertiaire IDF Grands Projets, SDEL IMTEC, Saga Tertiaire and Uxello Tertiaire Île-de-France is also in charge of the major technical works package.This package comprises the electrical, HVACSE, plumbing and fire safety works. An individual fresh air intake on each storey will make the Hekla tower the first high-rise in Europe to have a decentralised ventilation system – and result in a gain in usable floor space.
The works started during the summer 2018 and will be completed in 2022.
