Work on the €124m (£107m) office tower will be carried out by subsidiaries GFC Construction and Bouygues Bâtiment Ile-de-France.
The Incity Tower, as it will be known, was designed by Valode & Pistre and AIA Architectes and it is being built for Sogelym Dixence. The tower’s spire will reach a height of 200m, making it taller than "The Pencil" in Part-Dieu, currently the tallest building in the city.
Incity will replace the old UAP tower, which has been taken down by Bouygues Construction. The new tower will form part of the transformation of the Part-Dieu business district in Lyon. It will have 44,145m² of floor space on 40 storeys and will accommodate around 2,700 employees.
The tower has been designed in line with the principles of sustainable construction. Incity will feature a thin double-skin facade of internal double glazing and external single glazing, designed to insulate the building while encouraging good airflow. The glazed facade will allow natural daylight to enter and so reduce the need for artificial light.
In all, the building is designed to consume less than 90 kWhPE/m²/year, as compared to between 300 and 800 kWhPE/m²/year for the previous generation of office towers.
Construction will take 32 months, with handover scheduled for late 2015. Roughly 400 people will be working on site at peak periods.
Jean-Claude Condamin, chairman of Sogelym Dixence, said: "I have enjoyed a relationship of trust with the directors of the Bouygues Construction Group for many years. We have managed to create a partnership together based on mutual esteem and respect on the part of both teams. I am particularly happy to be building Incity, an emblematic project for Lyon, with the Bouygues Construction Group."
