| Bouygues Batiment to renovate highest tower in La Defense Bouygues Bâtiment Ile-de-France, Bouygues Construction's subsidiary operating in the Paris region, has signed a renovation contract worth more than 300 million euros with Axa, Beacon Capital and Cogedim for the CB31 Tower in La Défense. The CB31 Tower (previously known as the Axa Tower), which comprises three wings and stands 155 m tall with 40 storeys above ground, will be raised 10 storeys to reach a total height of 218 m and become the tallest building in La Défense. The works also include 10-storey "levelling" of upper floors. The office floor space will be increased by nearly 10% to 87,000 sq. m. The entire structure will be reinforced and the building envelope will be totally rebuilt with close to 50,000 sq. m of slope glazing and curtain walling, including 30,000 sq. m of naturally ventilated double-skin façade. The CB31 Tower will win High Environmental Quality (HQE) certification as part of a far-reaching sustainable development approach. The renovation work will be carried out by the Rénovation Privée unit of Bouygues Bâtiment Ile-de-France and will last three years. write your comments about the article :: © 2008 Construction News :: home page |
